    SUMMARY: The Federal Trade Commission (``Commission'') proposes 
    commencing a rulemaking proceeding to amend its Trade Regulation Rule 
    Concerning the Labeling and Advertising of Home Insulation (``R-value 
    Rule'' or ``Rule''). The purpose of the rulemaking is to streamline and 
    increase the benefits of the Rule to consumers and sellers, minimize 
    its costs, and respond to the development and utilization of new 
    technologies to make American homes more energy efficient and less 
    costly to operate. This document: First, summarizes public comments the 
    Commission received in response to a request for comments about the 
    need for the rule and its benefits and burdens; second, proposes 
    amendments to recognize technological advances in R-value testing and 
    specimen preparation procedures, and to clarify and streamline the 
    Rule's requirements; and third, solicits comments on the proposed 
    amendments and additional issues.
    
    DATES: Written comments must be submitted on or before November 15, 
    1999.
    
    ADDRESSES: Five paper copies of each written comment should be 
    submitted to the Office of the Secretary, Federal Trade Commission, 
    Room 159, 600 Pennsylvania Ave., N.W., Washington, D.C. 20580. All 
    comments also should be submitted, if possible, in electronic form, on 
    a 3\1/2\ inch personal computer diskette, with a label on the diskette

    SUPPLEMENTARY INFORMATION:
    
    I. Introduction
    
        According to the U.S. Department of Energy (``DOE''), the typical 
    U.S. family spends close to $1,300 each year on energy bills. DOE 
    statistics show that, typically, 44% of a homeowner's utility bill goes 
    for heating and cooling costs. DOE states that homeowners may be able 
    to reduce their energy bills from 10% to 50% by taking certain 
    steps.\1\ One of the major steps is increasing the amount of thermal 
    insulation in their existing homes, or purchasing additional insulation 
    when purchasing new homes.
    ---------------------------------------------------------------------------
    
        \1\ The amount of energy savings a particular homeowner can 
    save, of course, will vary depending on individual circumstances. 
    DOE provides recommendations about the amount of insulation 
    homeowners need, based on local heating and cooling costs and 
    climate conditions. DOE's recommendations are based on the cost-
    effectiveness of the recommended insulation levels. for more 
    information, see http://www.eren.doe.gov/consumerinfo/
    energy__>savers/ on the Internet, or telephone the U.S. 
    Department of Energy's Energy Efficiency and Renewable Energy 
    Clearinghouse (``EREC'') at (800) 363-3732.
    ---------------------------------------------------------------------------
    
        To assist consumers in reducing energy bills, the President of the 
    United States announced in 1998 the Partnership for Advancing 
    Technology in Housing (``PATH''). PATH is a public/private sector 
    initiative that seeks to expand the development and utilization of new 
    technologies in order to make American homes stronger, safer and more 
    durable; more energy efficient and environmentally friendly; easier to 
    maintain and less costly to operate; and more comfortable and exciting 
    to live in. The PATH effort is expected to result in, among other 
    things, improved energy efficiency and the increased market acceptance 
    of new housing technologies.
        The FTC has long recognized the importance of energy expenditures 
    on housing to homeowners and other consumers. In 1979, the Commission 
    promulgated the R-value Rule, 16 CFR Part 460. The R-value Rule 
    requires that thermal insulation manufacturers and other sellers 
    disclose the thermal performance of their products, based on uniform 
    testing procedures adopted by the thermal insulation industry. The 
    purpose of this Rule is to provide consumers with information about 
    thermal insulation products, based on uniform standards, that allows 
    them to make meaningful, cost-based purchasing decisions among 
    competing products. As part of its ongoing program to review all its 
    rules and guides to ensure that they provide the maximum benefits at 
    the lowest cost, the Commission reviewed the R-value Rule in 1995 and 
    adopted amendments in 1996 to support the use of the most current 
    testing procedures available and to streamline the Rule.
        To increase further the benefits of the Rule, reduce its costs, and 
    support PATH's goals to make American homes more energy efficient, and 
    less costly to operate, the Commission now proposes to consider 
    amending the Rule to recognize the latest technology available. At this 
    time the Commission proposes only a few limited amendments, which are 
    designed to clarify the Rule, make disclosure requirements consistent 
    for competing types of loose-fill insulation products, require the most 
    current procedures for preparing R-value test specimens and conducting 
    R-value tests, delete disclosures for a type of insulation that no 
    longer is sold, and reduce disclosure requirements for retailers. 
    Regarding these issues, the Commission believes that there is 
    sufficient information to propose amendments. Regarding other issues, 
    the Commission is not proposing amendments at this time, but seeks 
    additional comment that could ultimately result in proposed amendments. 
    The Commission, therefore, requests comments on additional issues, such 
    as whether the Commission should revise the Rule to cover additional 
    products or to require the disclosure of in-use performance values (as 
    opposed to laboratory tests that are conducted under static, uniform 
    conditions) or of the performance of building systems. In addition, the 
    Commission requests comments on whether it should adopt additional test 
    specimen preparation requirements for specific types and forms of 
    insulation products to account for various factors that affect R-
    values; adopt additional or updated testing requirements; and revise 
    the disclosure requirements for manufacturers' label and fact sheets, 
    advertisements and other promotional materials, and for professional 
    installers, new home sellers, and retailers.
    
    II. The R-Value Rule
    
        The Commission promulgated the R-value Rule on August 29, 1979 \2\ 
    under section 18 of the Federal Trade Commission Act (``FTC Act''), 15 
    U.S.C. 57a. The Rule became effective on September 30, 1980. The Rule 
    specifies substantiation and disclosure requirements for those who sell 
    thermal insulation products for use in the residential market, and 
    prohibits certain claims unless they are true. The primary
    
    [[Page 48025]]
    
    disclosure required is the insulation product's ``R-value'' ``R-value'' 
    is the recognized numerical measure of the ability of an insulation 
    product to restrict the flow of heat and, therefore, to reduce energy 
    costs. R-values may be expressed per unit of thickness (e.g., one inch) 
    or for the total thickness of a particular insulation product or 
    installation. The higher the R-value, the better the product's 
    insulating ability.
    ---------------------------------------------------------------------------
    
        \2\ Final trade regulation rule (``Statement of Basis and 
    Purpose'' or ``SBP''), 44 FR 50218 (1979).
    ---------------------------------------------------------------------------
    
        On April 6, 1995, as part of its ongoing regulatory review program, 
    the Commission solicited public comments about the economic impact of 
    and current need for the R-value Rule.\3\ 60 FR 17492 (1995). At the 
    same time, the Commission solicited comments on a petition 
    (``Petition'') from Ronald S. Graves, who at that time was a Research 
    Staff Member, Materials Analysis Group, Martin Marietta Energy System, 
    Inc. (which operates Oak Ridge National Laboratory (``ORNL'') for the 
    U.S. Department of Energy (``DOE'')). The Petition requested that the 
    Commission approve an additional (fifth) R-value test procedures, as an 
    optional test procedure for determining the R-value of home insulation 
    under the Rule. The test procedure had been issued by the American 
    Society for Testing and Material (``ASTM''), a voluntary industry 
    standards organization.
    ---------------------------------------------------------------------------
    
        \3\ The Commission previously reviewed the Rule in 1985 under 
    the Regulatory Flexibility Act, 5 U.S.C. 610, to determine the 
    economic impact of the Rule on small entities. Based on that review, 
    the Commission determined that: there was a continuing need for the 
    Rule; there was no basis to conclude that the Rule had a significant 
    impact on a substantial number of small entities; there was no basis 
    to conclude that the Rule should be amended to minimize its economic 
    impact on small entities; the Rule did not generally overlap, 
    duplicate, or conflict with other regulations; and technological, 
    economic, and other changes had not affected the Rule in any way 
    that would warrant amending the Rule. 50 FR 13246 (1985).
    ---------------------------------------------------------------------------
    
        In response to the request for comments, the Commission received 42 
    comments from manufacturers of cellular plastics, cellulosic, mineral 
    fiber, and reflective insulation products; manufacturers of structural 
    insulated panels; trade associations comprised of manufacturers of 
    insulation products and structural insulated panels, professional 
    installers, and roofing contractors; independent technical consultants 
    to industry; a government contractor; and individual consumers.\4\
    ---------------------------------------------------------------------------
    
        \4\ The April 6, 1995 request for comments is filed as document 
    number B172394. The comments filed in response to the request for 
    comments are listed in the attached Appendix, alphabetically 
    according to the citation abbreviations used in this notice. The 
    comments are filed as document numbers B17239400001, B17239400002, 
    etc. In today's notice, the comments are cited as #01, #02, etc. 
    They are available for inspection in Room 130 at the Commission's 
    Headquarters at 600 Pennsylvania Avenue, NW, Washington, DC.
    ---------------------------------------------------------------------------
    
        Thirty of the 31 comments that addressed the current need for the 
    Rule stated that there is a continuing need for the Rule (and its 
    requirements that manufacturers and other sellers substantiate and 
    disclose the R-values of home insulation products). Twenty-four 
    comments described benefits that the current Rule, and the disclosure 
    of R-values and related information, confer on consumers and home 
    insulation sellers, including: (1) Giving consumers the basic thermal 
    performance information (i.e., R-values) they need to select products 
    with the R-value they want; (2) giving consumers R-value information in 
    a uniform manner that facilitates easy comparison of competing 
    products; (3) requiring that R-value claims be substantiated so 
    consumers receive what they are promised; (4) helping consumers save 
    energy (and heating and cooling costs) by preventing misrepresentations 
    about R-values of insulation products; (5) saving consumers money by 
    eliminating marketing practices that lead them to over- or 
    underinsulate; (6) improving the quality and consistency of home 
    insulation and encouraging the development of advanced products; and 
    (7) creating a ``level playing field'' for competing insulation 
    sellers.\5\ Most of the comments stated that the costs the Rule imposes 
    on consumers and sellers are minimal.
    ---------------------------------------------------------------------------
    
        \5\ In addition to these benefits, one comment explained that 
    utility companies have embraced the Rule and developed their own 
    energy savings programs that depend on the Rule to protect 
    consumers. The comment also stated that state departments of 
    consumer affairs have used the Rule as a model in writing their 
    regulations, which has led to state enforcement that has generated 
    publicity and educated consumers.
    ---------------------------------------------------------------------------
    
        Based on the comments, the Commission determined that there is a 
    continuing need for the Rule, published its determination to retain it, 
    and adopted several technical, non-substantive amendments to support 
    the use of the most current testing procedures available and to 
    streamline the Rule.\6\ 61 FR 13659, at 13659-62, 13665 (1996). The 
    comments also discussed other issues and recommended that the 
    Commission consider additional Rule amendments. These comments, the 
    Commission's discussion of the issues the comments raised, proposed 
    revisions to the Rule, and objectives and regulatory alternatives to 
    the proposed revisions, are summarized in Part IV.
    ---------------------------------------------------------------------------
    
        \6\ These amendments: (1) Revised section 460.5 of the Rule to 
    allow the use of an additional ASTM test procedure as an optional, 
    but not required, test procedure to determine the R-value of home 
    insulation; (2) revised section 460.5 to require the use of current, 
    updated versions of other ASTM R-value test methods cited in the 
    rule; (3) added an Appendix summarizing the exemptions from specific 
    requirements of the Rule that the Commission previously granted for 
    certain classes of persons covered by the Rule; and (4) revised 
    section 460.10 of the Rule to cross-reference the Commission's 
    enforcement policy statement for foreign language advertising in 16 
    CFR 14.9 and deleted the previous Appendix to the Rule because it 
    merely repeated the text of 16 CFR 14.9.
    ---------------------------------------------------------------------------
    
    III. Overview of the Rule \7\
    ---------------------------------------------------------------------------
    
        \7\ This part of the notice outlines the coverage and 
    requirements of the R-value Rule. Home insulation sellers should be 
    aware, however, that additional Commission rules or guides may also 
    apply to them. For example, the Commission's rules concerning 
    Disclosure of Written Consumer Product Warranty Terms and 
    Conditions, and the Pre-sale Availability of Written Warranty Terms, 
    16 CFR Parts 701 and 702, specify requirements concerning warranties 
    for home insulation products; the Commission's Guides for the Use of 
    Environmental Marketing Claims, 16 CFR Part 260, address the 
    application of section 5 of the FTC Act, 15 U.S.C. 45, to 
    environmental advertising and marketing claims (e.g., claims 
    concerning the amount of recycled material a product contains). 
    Further, section 5 of the FTC Act declares that unfair or deceptive 
    acts or practices are unlawful, and requires that advertisers and 
    other sellers have a reasonable basis for advertising and other 
    promotional claims before they are disseminated. See Deception 
    Policy Statement, Letter from the Commission to the Honorable John 
    D. Dingell, Chairman, Committee on Energy and Commerce, U.S. House 
    of Representatives (Oct. 14, 1983), reprinted in Cliffdale Assocs., 
    Inc., 103 F.T.C. 110 (1984); Statement of Policy on the Scope of the 
    Consumer Unfairness Jurisdiction, Letter from the Commission to the 
    Honorable Wendell H. Ford, Chairman, Consumer Subcommittee,

    Representatives, and the Honorable John C. Danforth, Ranking 
    Minority Member, Consumer Subcommittee, Committee on Commerce, 
    Science, and Transportation, U.S. Senate (Dec. 17, 1980), reprinted 
    in International Harvester Co., 104 F.T.C. 949 (1984); and Policy 
    Statement Regarding Advertising Substantiation, 49 FR 30999 (1984), 
    reprinted in Thompson Medical Co., 104 F.T.C. 839 (1984).
    ---------------------------------------------------------------------------
    
    A. Products Covered
    
        The R-value Rule covers all ``home insulation products.'' Under the 
    Rule, ``insulation'' is any product mainly used to slow down the flow 
    of heat from a warmer area to cooler area, for example, from the heated 
    interior of a house to the exterior during the winter through exterior 
    walls, attic, floors over crawl spaces, or basement. ``Home 
    insulation'' includes insulation used in all types of residential 
    structures. The Rule automatically covers new types or forms of 
    insulation marketed for use in the residential market, whether or not 
    they are specifically referred to in the Rule. The Rule does not cover 
    pipe insulation, or any type of duct insulation except for duct wrap. 
    The Rule does not cover insulation products sold for use in commercial 
    (including industrial) buildings. It does not apply to other products 
    with insulating characteristics, such as storm windows or storm doors.
        Home insulation includes two basic categories: ``mass'' insulations 
    and
    
    [[Page 48026]]
    
    ``reflective'' insulations. Mass insulations reduce heat transfer by 
    conduction (through the insulation's mass), convection (by air movement 
    within and through the air spaces inside the insulation's mass), and 
    radiation. Reflective insulations (primarily aluminum foil) reduce heat 
    transfer not through the mass of the product, but, when installed 
    facing an airspace, by increasing the thermal resistance of the 
    airspace by reducing heat transfer by radiation through it. 44 FR at 
    50219. Within these basic categories, home insulation is sold in 
    various types (``type'' refers to the material from which the 
    insulation is made, e.g., fiberglass, cellulose, polyurethane, aluminum 
    foil) and forms (``form'' refers to the physical form of the product, 
    e.g., batt, dry-applied loose-fill, spray-applied, boardstock, multi-
    sheet reflective).
    
    B. Parties Covered
    
        The Rules applies to home insulation manufacturers, professional 
    installers, retailers who sell insulation to consumers for do-it-
    yourself installation, and new home sellers (including sellers of 
    manufactured housing). It also applies to testing laboratories that 
    conduct R-value tests for home insulation manufacturers or other 
    sellers who use the test results as the basis for making R-value claims 
    about home insulation products.
    
    C. Purpose of the Rule
    
        The main reason consumers purchase home insulation is to reduce 
    energy expenditures to heat and cool their homes. To assist consumers, 
    the Rule requires sellers (including insulation manufacturers, 
    professional installers, new home sellers, and retailers) to disclose 
    the insulation product's R-value and related information, prior to 
    retail sale, based on uniform, industry-adopted standards. This 
    information enables consumers to evaluate how well a particular 
    insulation product is likely to perform, to determine whether the cost 
    of the insulation is justified, and to make meaningful, cost-based 
    purchasing decisions among competing products.
    
    D. Basis for the Rule
    
        The Commission issued the R-value Rule to prohibit, on an industry-
    wide basis, specific unfair or deceptive acts or practices. When it 
    issued the Rule, the Commission found that the following acts or 
    practices were prevalent in the home insulation industry and were 
    deceptive or unfair, in violation of section 5 of the FTC Act, 15 
    U.S.C. 45: (1) Sellers had failed to disclose R-value, and caused 
    substantial consumer injury by impeding the ability of consumers to 
    make informed purchasing decisions, 44 FR at 50222-23; (2) the failure 
    to disclose R-values, which vary significantly among competing home 
    insulation products of the same thickness and price, misled consumers 
    when they bought insulation on the basis of price or thickness alone, 
    Id. at 50223; (3) sellers had exaggerated R-values, often failing to 
    take into account factors (e.g., aging, settling) known to reduce 
    thermal performance, Id. at 50223-24; (4) sellers had failed to inform 
    consumers about the meaning and importance of R-value, which consumers 
    need to understand R-values, Id. at 50224; (5) sellers had exaggerated 
    the amount of savings of fuel bills that consumers could expect, and 
    often failed to disclose that savings will vary depending on the 
    consumer's particular circumstances, Id.; and (6) sellers had falsely 
    claimed that consumers would qualify for tax credits through the 
    purchase of home insulation, or that products had been ``certified'' or 
    ``favored'' by federal agencies, Id.
    
    E. Requirements of the Rule
    
        The Rule requires that manufacturers and others who sell home 
    insulation determine and disclose each product's R-value (and related 
    information--e.g., thickness, coverage area per package) on package 
    labels and manufacturers' fact sheets. R-value ratings vary among 
    different types and forms of home insulations and among products of the 
    same type and form. The Rule requires that R-value claims to consumers 
    about specific home insulation products be based on uniform R-value 
    test procedures that measure thermal performance under ``steady-state'' 
    (i.e. ``static'') conditions.\8\ Mass insulation products may be tested 
    under any of the test methods, reflective insulation products must be 
    tested according to either ASTM C 236-89 (1993) or ASTM C 976-90, which 
    can determine the R-value of insulation systems (such as those that 
    include one or more air spaces).\9\ The tests must be conducted at a 
    mean temperature of 75 deg.F. The tests on mass insulation products 
    must be conducted on the insulation material alone (excluding any 
    airspace).
    ---------------------------------------------------------------------------
    
        \8\ Section 460.5 of the Rule requires that the R-values of home 
    insulation products be based on one of the following R-value test 
    procedures adopted by ASTM: (1) ASTM C 177-85 (Reapproved 1993): 
    Standard Test Method for Steady-State Heat Flux Measurements and 
    Thermal Transition Properties by Means of the Guarded-Hot-Plate 
    Apparatus (``ASTMC C 177-85 (1993)''or ``Guarded Hot Plate''); (2) 
    ASTM C 236-89 (Reapproved 1993): Standard Test Method for Steady-
    State Thermal Performance of Building Assemblies by Means of a 
    Guarded Hot Box (``ASTM C 236-89 (1993)'' or ``Guarded Hot Box''); 
    (3) ASTM C 518-91: Standard Test Method for Steady-State Heat Flux 
    Measurements and Thermal Transmission Properties by Means of the 
    Heat Flow Meter Apparatus (``ASTM C 518-91'' or ``Heat Flow 
    Meter''); (4) ASTM C 976-90; Standard Test Method for Thermal 
    Performance of Building Assemblies by Means of a Calibrated Hot Box 
    (``ASTM C 976-90'' or ``Calibrated Hot Box'')); and (5) ASTM C 1114-
    95; Standard Test Method for Steady-State Thermal Transmission 
    Properties by Means of the Thin-Heater Apparatus (``ASTM C 1114-
    92''or ``Thin-Heater Apparatus''). R-values determined according to 
    ASTM C 177-85 (1993) or ASTM C 518-91 must be reported in accordance 
    with ASTM C 1045-90: Standard Practice for Calculating Thermal 
    Transmission Properties from Steady-Heat Flux Measurements (``ASTM C 
    1045-90''). The Commission gave manufacturers and others the option 
    of choosing among those test procedures because it determined that 
    all are highly accurate and reproducibly steady-state test methods 
    that yield uniform and reliable results. 44 FR at 50226; Final rule, 
    55 FR 10053, at 10054 (1990); Final rule, 61 FR 13659, at 13662-63 
    (1996). ASTM reviews and revises each of these procedures 
    periodically. Under section 460.7 of the Rule, the Commission will 
    accept, but not require, the use of a revised version of any of 
    these standards 90 days after ASTM adopts and publishes the 
    revision. The Commission may, however, reopen the rulemaking 
    proceeding during a 90-day period or at any later time to consider 
    whether it should require use of the revised procedure or reject it 
    under section 460.5 of the Rule. 61 FR at 13663.
        \9\ The R-value of a single-sheet reflective insulation product 
    may be determined according to an alternative method. See Part 
    IV.D.2, infra.
    ---------------------------------------------------------------------------
    
        When it promulgated the Rule, the Commission found that certain 
    factors, such as aging or settling, affect the thermal performance of 
    home insulation products. 44 FR at 50219-20, 50227-28. To ensure that 
    R-value claims take these factors into account, the Rule mandates that 
    the required R-value tests for polyurethane, polyisocyanurate, and 
    extruded polystyrene insulation products be conducted on test specimens 
    that fully reflect the effect of aging,\10\ and for loose-fill 
    insulation products on test specimens that fully reflect the effect of 
    settling.\11\

        \11\ See Part IV.C.2.a, infra.
    ---------------------------------------------------------------------------
    
        Specific disclosures must be made: (1) By manufacturers on product 
    labels and manufacturers' fact sheets; (2) by professional installers 
    and new home sellers on receipts or contracts; and (3) by 
    manufacturers, professional installers, and retailers in advertising 
    and other promotional materials (including those on the Internet) that 
    contain an R-value, price, thickness, or energy-savings claim, or 
    compare one type of insulation to another. Manufacturers and other 
    sellers must have a ``reasonable basis'' for any energy savings claims 
    they make.\12\
    ---------------------------------------------------------------------------
    
        \12\ Although the Rule does not specify how energy savings 
    claims must be substantiated, the Commission explained that 
    scientifically reliable measurements of fuel use in actual houses or 
    reliable computer models or methods of heat flow calculations would 
    meet the reasonable basis standard. 44 FR at 50233-334. Sellers 
    other than manufacturers can rely on the manufacturer's claims 
    unless they know or should know that the manufacturer does not have 
    a reasonable basis for the claims.

    IV. Discussion of Comments, Proposed Amendments, Objectives, and 
    Regulatory alternatives
    
        This part of the notice summarizes and discusses the issues raised 
    by the comments, including suggestions that the Commission revise the 
    Rule. In analyzing the comments, the Commission has considered whether 
    the suggested revisions would further the Commission's objective of 
    ensuring that consumers receive information about home insulation 
    products prior to purchase in a uniform, reliable, and substantiated 
    manner, so that they can evaluate how well a particular product is 
    likely to perform and make meaningful, cost-based purchasing decisions. 
    In addition, the Commission has considered alternatives to amending the 
    Rule to impose new requirements on an industry-wide basis, such as 
    dealing with questionable claims or practices on a case-by-case basis, 
    or exploring other mechanisms such as consumer and business education 
    or industry self-regulation. Below, the Commission explains, on an 
    issue-by-issue basis, whether it proposes amending the Rule as 
    suggested by the comments. Both Parts IV and V include specific issues 
    and questions on which the Commission solicits public comments.
    
    A. Disclosing Thermal Performance of Additional Products
    
    1. Residential Pipe and Duct Insulations
    
    Comments
    
        Dr. Kenneth E. Wilkes, for ORNL, recommended amending the Rule to 
    include pipe insulations and all types of duct insulations, and listed 
    the applicable ASTM test methods that apply to these products. Dr. 
    Wilkes stated that the disclosure of R-value information would provide 
    important information for purchasers of these products.\13\
    ---------------------------------------------------------------------------
    
        \13\ ORNL/Wilkes, #29, at 3.
    ---------------------------------------------------------------------------
    
    Discussion
    
        The Commission excluded pipe insulation based on uncontroverted 
    evidence in the original rulemaking proceeding that it was used 
    primarily to prevent moisture condensation on low temperature lines, 
    not for energy conservation; that R-value was not a reliable basis for 
    comparing the performance of pipe insulations; and that pipe 
    insulations were not commonly advertised in terms of energy-savings 
    potential.\14\ Similarly, it excluded duct insulations other than duct 
    wrap because only duct wrap was used extensively in the residential 
    setting. 44 FR at 50238 n.170. The Commission's staff has reviewed 
    current consumer advertising for these products and found no 
    information to indicate that these facts have changed. Unless 
    interested parties have information that sellers are misrepresenting 
    the thermal performance of these products to consumers, the Commission 
    will not propose extending the Rule to cover them.

    Proposed Trade Regulation Rule (16 CFR Part 460), July 1978 (``Staff 
    Report''), at 21-22, 188.
    ---------------------------------------------------------------------------
    
    2. Non-residential Insulations
    
    Comments
    
        Two comments suggested extending the Rule to cover insulation 
    products used in all buildings, not just residential applications. Dr. 
    David W. Yarbrough, for Tennessee Technological University (``TN 
    Tech.''), asserted that extending the Rule to cover commercial building 
    insulations would improve the energy efficiency of buildings and would 
    contribute to the nation's energy conservation effort without imposing 
    a measurable increased cost on manufacturers.\15\ Dr. Wilkes, for ORNL, 
    stated that the Rule has improved both the marketplace and the 
    technology for home insulations and contended that similar improvements 
    are needed in the commercial market and would occur if the Rule's 
    coverage were expanded.\16\ In contrast, Celotex stated that the 
    Commission should not extend the Rule to cover commercial applications 
    because commercial insulations are purchased primarily by professional 
    architects, engineers, and specification writers.\17\

    ---------------------------------------------------------------------------
    
    Discussion
    
        Although applying the Rule to thermal insulation products used in 
    commercial buildings might provide information to purchasers that could 
    improve the energy efficiency of buildings, and otherwise prove useful, 
    the comments do not demonstrate that sellers of commercial insulations 
    are engaged in unfair or deceptive acts or practices that would justify 
    expanding the Rule. Furthermore, in many instances, thermal insulation 
    purchasing decisions for commercial building applications are made by 
    architects or engineers. These professionals may require R-value and 
    other performance information based on circumstances different than the 
    uniform approach the Commission determined was necessary to provide 
    accurate and understandable information to individual consumers to 
    compare competing products and make purchasing decisions.
        In limiting the disclosure requirements to materials distributed 
    ``for consumer use,'' the Commission recognized that insulation 
    manufacturers often prepare detailed, technical data for building 
    industry professionals, who should already be informed concerning 
    thermal insulation performance. The Commission also recognized that 
    manufacturers may wish to provide these professionals with additional 
    information or with information in a different form from that required 
    for consumer use. 44 FR at 50225.
        For these reasons, the Commission does not propose extending the 
    Rule to cover sales to the commercial market. If interested parties 
    have evidence that sellers in this market are misrepresenting the 
    thermal performance of insulation products or are engaging in other 
    unfair or deceptive practices, however, the Commission invites them to 
    submit this information.
    
    B. Disclosing In-Use Thermal Performance Values
    
    1. Performance of Insulations in Actual Use
        Eleven comments discussed seasonal and other variables that can 
    affect the R-value of insulation products in actual use, and suggested 
    that the Rule does not sufficiently account for these factors.\18\

    Comments Regarding Factors That Affect Performance in Attics During 
    Winter Conditions
    
        Ten of these comments discussed the reduction in R-value of very 
    low density fibrous insulations (e.g., those at approximately 0.7 
    pounds per cubic foot or less) installed in open or vented attics that 
    can result from convective currents when the outside temperature (and 
    that in the attic) is particularly low.\19\ CIMA stated that when the 
    Rule was promulgated it was assumed that R-
    
    [[Page 48028]]
    
    value was relatively unchanging over a wide range of temperatures. CIMA 
    asserted that subsequent research by ORNL has shown a reduction of 
    steady-state R-values caused by convective heat loss in very low 
    density fiber insulation materials during very cold periods, when the 
    temperature difference (delta T) between the heat area of a home and 
    its cold attic becomes particularly great. CIMA stated that this 
    phenomenon can reduce the steady-state R-value of affected products 
    from 10% of a delta T of 50  deg.F to 55  deg.F (17  deg.F to 25  deg.F 
    in the attic of a home heated to 72  deg.F) to as much as 40% at a 
    delta T of 90  deg.F (-18  deg.F in the attic of a home heated to 72 
    deg.F), which can occur during the most severe winter conditions in 
    some portions of the United States. CIMA recommended that the 
    Commission require that insulation manufacturers provide winter design 
    correction factors in coverage charts to compensate for R-value erosion 
    due to convective heat loss, and require that, if insulation material 
    is not subject to R-value loss under cold conditions, the manufacturer 
    state on the package label that the insulation is not subject to 
    convective heat loss at winter attic temperatures above -20  deg.F.\20\

        \20\ CIMA, #19, at 3-4.
    ---------------------------------------------------------------------------
    
        Dr. Wilkes, for ORNL, pointed out that tests on very low density 
    loose-fill fiberglass insulations with an airspace above the insulation 
    (as in an open attic application) gave R-values that decreased by more 
    than 50% from those determined at a mean test temperature of 75  deg.F 
    value, when they were tested with a delta T greater than 72  deg.F and 
    a mean test temperature of 70  deg.F. Dr. Wilkes explained that ASTM is 
    developing a method of determining the thermal performance of attic 
    insulations during winter conditions, ASTM C 1373,\21\ and suggested 
    that the Commission incorporate it into the Rule when it is adopted. 
    This method is still under consideration by ASTM.
    ---------------------------------------------------------------------------
    
        \21\ Standard Practice for Determination of Thermal Resistance 
    of Attic Insulation Systems Under Simulated Winter Conditions 
    (``ASTM C 1373'').
    ---------------------------------------------------------------------------
    
        Mr. Tranmer, for GreenStone, asserted that several factors in 
    addition to R-values that are determined under steady-state conditions 
    have a major effect on product performance, such as air permeability 
    and temperature differential. Mr. Tranmer stated that a measurement 
    known as the Rayleigh number \22\ provides a more complete indication 
    of the effect that the combination of R-value, air permeability, and 
    temperature differential have on insulation materials under specific 
    conditions, and that it represents a more accurate measure of 
    insulating capabilities than R-value alone. He suggested that the 
    Commission require the Rayleigh number on packages and promotional 
    materials to give consumers a better measure of the overall 
    effectiveness of insulation products.\23\
    ---------------------------------------------------------------------------
    
        \22\ The Rayleigh number is a measure of the tendency of air to 
    move. In the context of very low density thermal insulations 
    installed on the floor of an open attic during very cold periods, 
    the Rayleigh number is a ratio between the buoyant force of warmer 
    air (the air at the bottom of the insulation near the heated 
    interior of the house) attempting to move upward and the resistance 
    of the insulation fibers against that upward air movement. The 
    higher the number, the stronger the buoyant force, and the greater 
    the reduction of the insulation's steady-state R-value.
        \23\ GreenStone/Tranmer, #20, at 2-3, See also GreenStone/Smith, 
    #32, at 2 (Rule leads consumers to believe that R-value is the most 
    important factor in comparing insulations; not sufficient merely to 
    state that other factors may affect insulation thermal performance 
    if other important factors can be quantified; require testing for 
    air permeability, R-value, and temperature difference to enable 
    disclosure of a relative insulation performance factor (Rayleigh 
    Number)), Hamilton, #22, at 2 (effects of convective heat loss on R-
    value could be communicated to consumers by an ``air resistance 
    index'' number to give them a reference to compare insulation for 
    certain applications; bag label should include warning about 
    convection effect on lighter-density materials below 20  deg.F); 
    Tascon, #35, at 1-2 (require determination of the effects of air 
    convection on R-value and depiction of that effect at representative 
    temperatures on coverage charts; require disclosure of the Rayleigh 
    number); Regal, #16, at 3 (insulation performance and cost 
    effectiveness should address not only R-value, but also resistance 
    to heat flow and to convective effects under winter design 
    conditions.).
    ---------------------------------------------------------------------------
    
        Mr. Tranmer also recommended that the Commission specify testing 
    with the ORNL Large Scale Climate Simulator to provide more accurate 
    information for all attic insulation products, and that these products 
    be tested at temperatures from -20 deg.F to +120 deg.F to provide 
    consumers with performance information specific to a particular climate 
    zone. He stated that, while the cost of testing in this apparatus is 
    approximately $20,000 (significantly more than the usual R-value test), 
    the benefits through increased energy savings would more than offset 
    the increase in testing costs.\24\
    ---------------------------------------------------------------------------
    
        \24\ GreenStone/Tranmer, #20, at 2-3.
    ---------------------------------------------------------------------------
    
        Citing research that heating energy consumption can vary 25% to 38% 
    in structures insulated to the same nominal R-value with different 
    insulation materials, CIMA similarly asserted that, by focusing only on 
    R-value, the current Rule has the effect of misleading consumers into 
    thinking that R-value is the only consideration when buying or 
    specifying insulation. Recognizing that presently there is no perfect 
    solution to this dilemma, CIMA suggested that Commission expand the 
    Rule to require manufacturers to disclose Rayleigh numbers for 
    materials under specific conditions. CIMA asserted that the Rayleigh 
    number combines the effects of R-value, air permeability, and 
    temperature difference to produce an expression of relative insulation 
    performance.
    
    Comments Regarding Factors That Affect Performance Under Winter Versus 
    Summer Conditions
    
        One commenter, Superior, contended that the R-value test procedures 
    presently required as the primary means of identifying heat transfer 
    are no longer valid, because they were developed almost exclusively for 
    winter conditions. Superior asserted that, with the post-World War II 
    advent of air conditioning and a higher concern for summer comfort, the 
    primary mode of heat transfer that should be measured is radiant heat. 
    Superior explained that R-value is a component of conductive heat 
    transfer, while radiant heat should be measured by its emissivity,\25\ 
    and contended that reflective insulations with one-half or less the 
    steady-state R-value of fiberglass will stop more heat transfer into 
    the home during summer conditions. Superior recommended that the 
    Commission require manufacturers of all insulations to disclose winter 
    and summer performance values, with the summer value determined 
    according to a test procedure other than R-value tests, which have very 
    little significance for radiant heat transfer during summer 
    conditions.\26\
    ---------------------------------------------------------------------------
    
        \25\ ``Emissivity'' is a numerical measurement of the ability of 
    a surface to reflect back radiant heat transfer. It is expressed as 
    a number between 0.0 and 1.0. The lower the emissivity, the greater 
    the ability to reflect radiant heat back. The inverse of emissivity 
    is the product's ``reflectivity'' (also called the ``reflectance'').
        \26\ Superior, #27, at 1.
    ---------------------------------------------------------------------------
    
    Discussion
    
        The Rule requires that R-values be determined according to ASTM 
    test methods that provide R-value measurements under ``steady-state'' 
    or ``static'' laboratory conditions. These test methods do not take 
    into account transient environmental factors, such as air circulation, 
    that can have a significant effect on insulation performance in actual 
    use (i.e., on site, or in situ). When it promulgated the Rule, the 
    Commission determined that, notwithstanding this limitation, these 
    steady-state tests were the most reliable and accurate test methods 
    available. In addition, evidence on the rulemaking record indicated 
    that, although environmental conditions might affect the R-value number 
    determined in steady-state tests, these conditions would affect 
    competing home insulation products in approximately the same manner. 
    Accordingly, the Commission
    
    [[Page 48029]]
    
    determined that use of the ASTM steady-state R-value test methods would 
    permit fair comparisons of product R-values on a standardized basis to 
    provide consumers with a reliable, uniform, and comparative base for 
    their purchasing decisions. 44 FR at 50225-26. At the same time, while 
    the Rule requires that R-values claimed must be based on the uniform 
    test methods specified in the Rule, manufacturers and other sellers may 
    provide additional, truthful, substantial information voluntarily to 
    consumers about the manner in which their products perform in actual 
    use.
        The Commission recognizes that the testing of insulation products 
    by means of steady-state laboratory testing procedures may not 
    duplicate precisely the performance of an insulation product in situ. 
    The thermal performance of any insulation product in actual use, 
    however, is a highly complex subject that involves a broad range of 
    parameters, including the design characteristics of the building and 
    the specific application in which the product is installed (e.g., open 
    attic, enclosed wall cavity), the geographical location, outside and 
    inside temperatures, air and moisture movement, proper installation, 
    and other variables. Determining the disclosing R-values under these 
    varying circumstances, only some of which may apply to a particular use 
    by a specific consumer, could result in multiple R-value disclosures 
    that might overload rather than assist consumers in comparing 
    insulation products and making purchase decisions. For these reasons, 
    the Commission does not at this time propose specific amendments to 
    require disclosures regarding in situ performance or multiple R-values 
    for different uses.
        Consumers, however, could benefit from the most up-to-date, 
    accurate, and useful information, based on the best available research 
    and substantiation. For example, in areas where a significant delta T 
    is predictable, consumers might want to install additional insulation 
    to take into account the reduction in R-value that might occur during 
    extreme conditions, or consider installing a higher density product. 
    The Commission, therefore, solicits comments on the alternatives to 
    steady-state R-values (e.g., Rayleigh numbers, R-value disclosures 
    based on temperature ranges for different regions of the country or for 
    different applications) suggested by the commenters, or other 
    alternatives, that would provide consumers with accurate, meaningful, 
    and understandable information relevant to their individual 
    circumstances. The Commission requests that commenters address: (1) 
    Specific alternative measurements that are available to describe the in 
    situ use of home insulation products better than the steady-state R-
    values required by the rule; (2) which in situ conditions should be 
    accounted for (and why); (3) whether (and how and to what extent) 
    different types or forms of home insulation products perform 
    differently under specific in situ conditions, and how significant this 
    different performance is under specific circumstances (e.g., how much 
    would the difference in performance in actual use make on the 
    consumer's annual fuel bill); (4) whether accepted test methods are 
    available to measure in situ performance (and the identity of specific 
    test methods); (5) how the results of in situ performance measurements 
    could be described in a meaningful manner to consumers; and (6) the 
    benefits and costs to consumers and sellers that would be associated 
    with the use of the alternatives. Among other things, comments are 
    requested to include data such as consumer research that demonstrate 
    whether disclosures of in situ performance would be meaningful and 
    understandable to consumers.
    2. Performance of Building System Components That Include Insulation
    
    Comments
    
        Four manufacturers of structural insulation panels (building 
    systems products that include insulation as a major component) \27\ and 
    a trade association representing such manufacturers \28\ supported 
    requiring the thermal efficiency testing of insulation systems, rather 
    than testing only individual insulation products. These comments 
    asserted that the Structural Insulated Panel (``SIP'') industry is 
    penalized by reporting R-values of the insulation components as the 
    measure of the thermal efficiency of panel system because such R-values 
    do not adequately represent the energy efficiency and thermal 
    effectiveness of the panel systems in comparison to insulated panels 
    may appear to have the same total R-value as some fiberglass batts used 
    in stick construction, ``[in a typical installation, using EPS foam in 
    a structural insulated panel, the EPS panel outperforms [a] fiberglass 
    batt by 20%.''

    ---------------------------------------------------------------------------
    
        Three of the manufacturers \29\ and the trade association, however, 
    apparently recognized that additional research and development would be 
    necessary before the Commission could require the testing and 
    disclosure of systems performance values. These comments recommended 
    that the Commission, along with several other federal agencies, work 
    with industry to develop consensus testing procedures to consider 
    factors such as air infiltration, thermal bridging, and moisture 
    effects on the performance of building systems, and provide resources 
    for testing and evaluation of the thermal performance and energy 
    efficiency of construction systems.

    Discussion
    
        The Rule covers home insulation products, including products made 
    up of home insulation and other components (such as structural 
    insulation panels) when they are marketed primarily to slow down the 
    flow of heat. These comments appear to be concerned primarily that the 
    Rule may penalize them by requiring that they disclose the R-value of 
    the insulation component of their panels, instead of the thermal 
    performance of their panels compared to the use of competing home 
    insulation products in other types of building construction. Although 
    the Rule requires that those who market home insulation test and 
    disclose the R-value of their insulation, it does not restrict sellers 
    from providing additional information about how their products perform 
    in actual use, if they are able to substantiate their claims. The 
    comments acknowledge that additional research would be required to 
    develop the procedures necessary to implement a requirement that 
    sellers include in their R-value disclosures information about how 
    their products perform in various types of construction, which would 
    depend on multiple variables. Even if such procedures were developed, 
    as a practical matter, it might be extremely difficult, and perhaps 
    impossible, to draft testing and disclosure requirements that could 
    take such variables into account in a manner that would be meaningful 
    to consumers, and where the benefits (e.g., better information for 
    consumers) outweighed the additional costs (e.g. for additional testing 
    and disclosures) that would be imposed.
        Accordingly, while the commission acknowledges the concerns 
    underlying these comments, it has determined not to propose amending 
    the Rule at this time to require the disclosure of insulation 
    performance based on testing of home insulation products in different 
    types of applications. The Commission
    
    [[Page 48030]]
    
    encourages interested parties to pursue the additional testing and 
    research that support a system-type disclosure format, and the 
    Commission's staff is available to provide advice about the type of 
    documentation that would be necessary for the Commission to propose 
    formal testing and disclosure requirements that include these 
    applications.
    
    C. Disclosing R-values that Account for Factors Affecting R-value
    
        The comments described in this section addressed issuers relating 
    to the Rule's R-value test specimen preparation requirements for 
    specific types and forms of home insulation products. All home 
    insulation products are covered by the Rule, regardless of whether they 
    are specifically referred to in the test specimen preparation 
    requirements or other provisions of the Rule. That is, they must be 
    tested for R-value under the test procedures specified in section 460.5 
    of the Rule and the R-value results of those tests must be disclosed to 
    consumers. In some instances the Rule specifies how test specimens must 
    be prepared for R-value tests. In other instances it does not, either 
    because the Commission determined it was not necessary to specify R-
    value test specimen preparation requirements, or because those products 
    were not being sold when the Commission conducted the original 
    rulemaking. These comments suggested adopting updated test specimen 
    preparation requirements or specifying test specimen preparation 
    requirements not currently required by the Rule.\30\
    ---------------------------------------------------------------------------
    
        \30\ In some instances, comments suggested that a specific test 
    specimen preparation procedure, although appropriate for the most 
    products of a certain type and form, might not be appropriate for a 
    specific product, for example, a loose-fill cellulose insulation 
    product with a lower than normal initial density. In such instances, 
    these comments suggested that use of in situ data to determine test 
    specimen preparation might be preferable to the specific procedure 
    designated in the Rule. Although the Commission is not proposing to 
    amend specific test specimen preparation requirements in the Rule to 
    include such a provision, manufacturers may file petitions for 
    exemption from the Rule's test specimen preparation requirements 
    under section 18(g) of the FTC Act, 15 U.S.C. 57a(g). Petitioners 
    should submit evidence substantiating why the test specimen 
    preparation procedure required by the Rule is not appropriate for a 
    particular product and why an alternative procedure or method would 
    be appropriate. The Commission will determine whether to grant an 
    exemption based on the petition, substantiating evidence submitted 
    with the petition, and public comments.

    1. Aging
    
    a. Cellular Plastics Insulations
    
        Certain types of cellular plastics insulations (polyurethane, 
    polyisocyanurate, extruded polystyrene boardstock insulations) are 
    manufactured in a process that results in a gas other than normal air 
    being incorporated into the voids in the products. This gives the 
    product an initial R-value higher than it would have if it contained 
    normal air (as do other types of insulations). A chemical process, 
    known as aging, causes the R-value of these insulations to decrease 
    over time as the gas is replaced by normal air. 44 FR at 50219-20. The 
    length of this aging process, which may continue over several years, 
    depends on whether the product is faced or unfaced, the permeability of 
    the facing, how well the facing adheres to the product, and other 
    factors.
        The Rule addresses this aging process by requiring that R-value 
    tests be performed on specimens that ``fully reflect the effect of 
    aging on the product's R-value.'' Section 460.5(a)(1) of the Rule 
    accepts the use of the ``accelerated aging'' procedure in General 
    Services Administration (``GSA'') purchase Specification HH-I-530A 
    (which was in effect at the time the Commission promulgated the Rule) 
    as a permissible ``safe harbor'' procedure, but also allows 
    manufacturers to use ``another reliable procedure.'' 44 FR at 50227-28. 
    The ``accelerated'' procedure was designed to age these insulations in 
    a shorter period than they would age under normal usage conditions. 
    Under the ``accelerated aging'' method in the GSA specification, test 
    specimens are aged for 90 days at 140  deg.F dry heat.
        GSA amended its specification in 1982 to allow the use of an 
    optional aging procedure (in addition to the ``accelerated'' method) 
    under which test specimens are aged for six months at 73 
    deg.F 4  deg.F and 50 percent 5 percent 
    relative humidity (with air circulation to expose all surfaces to the 
    surrounding environmental conditions). An industry group, the Roof 
    Insulation Committee of the Thermal Insulation Manufacturers 
    Association (``RIC/TIMA''), specified the use of similar conditions in 
    a technical bulletin it adopted at about the same time. In response to 
    adoption of the alternative aging procedure by GSA and RIC/TIMA, the 
    Commission's staff advised home insulation sellers that the alternative 
    procedure appeared to be reliable and could be used to age cellular 
    plastics insulations. The staff cautioned, however, the manufacturers 
    of insulations faced with materials that significantly retard aging may 
    need to age test specimens for a longer period of time, and that the 
    staff would consider whether the alternative procedure was acceptable 
    for specific products on a case-by-case basis.\31\
    ---------------------------------------------------------------------------
    
        \31\ See, e.g., staff opinion letter dated May 5, 1983, to 
    Manville Corporation. GSA thereafter rescinded its specification 
    (along with other insulation specifications) and now requires that 
    insulations purchased by the federal government comply with ASTM 
    insulation material specifications.
    ---------------------------------------------------------------------------
    
    Comments Regarding Which Aging Procedures Should Be Required
    
        Ten comments addressed how the Rule should treat the reduction in 
    R-values that occurs when cellular plastics insulation products 
    age.\32\ Two recommended requiring the use of aging procedures in 
    current ASTM specifications; one recommended requiring the use of a 
    different method being developed by ASTM; and one association 
    (representing 37 manufacturers) and two manufacturers appear to 
    question the accuracy of current aging procedures in determining long-
    term performance.

        Celotex and PIMA \33\ recommended deleting the reference to the

    unfaced polyisocyanurate and unfaced polyurethane),\35\ and ASTM C 578-

    contained in the revised GSA specification, although ASTM C 591-94 
    specifies that aging must be conducted according to the 180-day 
    procedure.

        Dr. Wilkes, for ORNL, stated that the Rule's aging requirement 
    should be improved and modified to account for technological changes. 
    He reported that ASTM was developing a new method of determining the 
    aged R-value of unfaced cellular plastics board stock insulations and 
    those with permeable facings based on R-value tests of thin samples 
    sliced from the center of the boards (which ASTM has now adopted as 
    ASTM C 1303-95).\37\ Under this method, a thin
    
    [[Page 48031]]
    
    test specimen is sliced from close to the center of the insulation 
    board. R-value measurements are taken over time, normally a 180-day 
    period, and the test specimen is kept in an environmental chamber when 
    R-value tests are not being conducted. The resulting R-values over time 
    are converted into an average value according to a specific 
    mathematical formula. Dr. Wilkes recommended that the Commission adopt 
    this ASTM method as the required procedure for deriving aged R-values 
    for these insulation products.

    ---------------------------------------------------------------------------
    
        Dr. Wilkes asserted that a satisfactory aging method for these 
    boardstock insulations with impermeable facers (e.g., aluminum) has not 
    yet been developed. He recommended that the Rule state this fact and 
    require ``direct'' aging of products with impermeable facers (i.e., 
    aging over time of samples as they are produced--at full thickness and 
    with facers attached). Finally, Dr. Wilkes recommended that the 
    Commission delete the phrase ``or another reliable procedure'' because 
    of its lack of specificity.\38\

        AMF, for itself and its 37 manufacturing partners, stated that the 
    reporting of different R-values for insulations that use gases, and 
    that are known to lose R-value over time as those gases diffuse, has 
    frustrated the original objective of the Rule to provide, a ``level 
    playing field.'' \39\ Plymouth Foam Products complained that ``[s]ome 
    [cellular plastics] foam insulation manufacturers are allowed to 
    represent their products with installed R-values of as high as eight 
    per inch, when, in fact, that value will reduce substantially over the 
    life of the product/structure.'' \40\ These comments recommended that 
    the Rule require testing and disclosure of R-values that more 
    accurately reflect the effect of aging on the R-value of cellular 
    plastics insulation products.

        Big Sky and Western contended that the practice of aging a test 
    specimen for six months, even at an elevated temperature, does not 
    provide a true picture of the R-value a consumer can expect over the 
    full life of the product.\41\ Big Sky suggested three options: (1) A 
    six-month accelerated aging process, with an additional 18-month hold 
    on the test specimens before they are tested for R-value; (2) 
    accelerated aging for 18 months; or (3) holding the test specimens for 
    three years. Western suggested that the Commission adopt an accelerated 
    aging test either from ASTM methods or the Corps of Engineers System.

    an aged R-value, when in fact it is only an R-value for insulation

    true indication of the in-service R-value, which can drop over 30% 
    within three years); Western, #14, at 1-2 (because polyisocyanurate 
    insulation has been sold based on R-values derived after six months 
    of aging under RIC/TIMA 281 or PIMA 100, consumers have been duped 
    into believing they are purchasing insulation that will deliver an 
    R-value of 7.2 per inch for the duration of its service; although 
    the true aged R-value of polyisocyanurate cannot be agreed upon, 
    5.56 per inch is often used and would be a more realistic figure).
    ---------------------------------------------------------------------------
    
    Discussion Regarding Which Aging Procedures Should Be Required
    
        Requiring manufacturers to age their insulation products for 
    several years before being able to test and market them would impose a 
    significant burden. Instead, the Rule allows the use of the GSA 
    ``accelerated aging'' procedure, or another reliable procedure. Because 
    some of the comments question whether the GSA accelerated aging 
    procedure or the procedures in ASTM specifications are adequate for all 
    types of cellular plastics insulation products (particularly those with 
    less permeable facers), the Commission solicits comments regarding the 
    length of time over which specific types and forms of cellular plastics 
    insulations age (including both unfaced products and those with 
    different kinds of facings); the effect of the aging process on 
    specific types and forms of cellular plastics insulations (i.e., the 
    overall reduction of R-value over time); the accuracy of different 
    aging procedures to reflect long-term aging of specific types and forms 
    of cellular plastics insulation products; which aging procedures the 
    Commission should require for which types of cellular plastics 
    insulation products; the burdens that would be imposed on manufacturers 
    and other sellers by requiring the use of specific aging procedures; 
    and how the Commission should deal with products for which adequate 
    aging procedures do not currently exist (e.g., those with relatively 
    non-permeable facings).
    
    Comments Regarding Which Cellular Plastics Insulations Should Be Aged 
    for R-value Testing
    
        NAIMA recommended requiring R-value testing on aged samples of 
    ``other foam plastic insulation'' products (in addition to the types 
    currently enumerated) and recordkeeping of the age of the test 
    specimen. NAIMA asserted that present and future foam insulations not 
    currently covered by the aging requirement should be tested and labeled 
    to reflect the effects of aging, but did not submit data to demonstrate 
    whether other existing cellular plastics, or foam, insulations are 
    subject to aging. According to NAIMA, the requirement would impose no 
    extra testing or labeling burdens on manufacturers of insulations that 
    are not subject to aging.\42\
    ---------------------------------------------------------------------------
    
        \42\ NAIMA, #24, at 2, 4.
    ---------------------------------------------------------------------------
    
    Discussion Regarding Which Cellular Plastics Insulations Should Be Aged 
    for R-value Testing
    
        The Commission required R-value testing of aged specimens only for 
    extruded polystyrene, polyurethane, and polyisocyanurate insulations 
    because these were the only types of insulations discussed during the 
    rulemaking proceeding that included blowing agents subject to the aging 
    process. The Commission agrees that manufacturers of additional types 
    of cellular plastics, or foam, insulations that are subject to the 
    aging process should be required to test aged specimens and disclose 
    aged R-values, and to maintain testing records identifying the aging 
    procedure used. The Commission, therefore, solicits comments on what 
    additional types or forms of insulations are subject to the aging 
    process.
    
    b. Reflective Insulations
    
    Comments
    
        NAIMA recommended that the Commission require that reflective 
    (aluminum foil) insulation products be tested for emissivity and R-
    value ``using samples that fully reflect the effect of aging'' on the 
    product's emissivity and R-value. NAIMA asserted that thermal 
    performance claims for reflective insulations, as for cellular plastics 
    insulations, should reflect the effects of aging (in this case, the 
    accumulation of dust or corrosion of the foil). NAIMA did not submit 
    evidence that dusting or corrosion is a problem that degrades the R-
    value of reflective insulations in actual applications, and did not 
    suggest a specific test method or procedure that should be used to 
    determine the effects of this type of aging on reflective 
    insulations.\43\

    ---------------------------------------------------------------------------
    
    Discussion
    
        The Commission believes that claims for all types of home 
    insulation products should take into account factors that affect the 
    products' thermal performance. The Commission, therefore, invites 
    interested parties to comment on whether dusting or
    
    [[Page 48032]]
    
    corrosion of reflective insulations in actual applications is a problem 
    resulting in lower R-values than claimed, the extent of any degradation 
    of R-value, and how the effect of dusting or corrosion on R-value could 
    most accurately be determined.
    2. Settling
    
    a. Loose-fill and Stabilized Insulations in Attics
    
        In the original rulemaking proceeding, the Commission determined 
    that all dry-applied loose-fill insulation products tend to settle 
    after being installed in open (or unconfined) areas such as attics. 
    Settling lowers the product's thickness, increases its density, and 
    affects its total R-value.\44\ The amount of settling depends on 
    several factors, including the raw materials and manufacturing process 
    used, and the installer's application techniques (which affect the 
    insulation's initial thickness and density).
    ---------------------------------------------------------------------------
    
        \44\ Settling of loose-fill cellulose insulation reduces the 
    product's total R-value, often decreasing it proportionate to the 
    amount of settling. Settling of loose-fill mineral fiber insulation 
    also affects the product's total R-value, but the reduction in total 
    R-value may be less than the reduction in thickness. E.g., ORNL/
    Yarbrough, #28, at References 1, 2; ORNL/Wilkes, #29, at References 
    9, 10.
    ---------------------------------------------------------------------------
    
        To ensure that claims made to consumers are based on long-term 
    thickness and density after settling, the Rule requires that the R-
    value of each dry-applied loose-fill home insulation product for these 
    applications be determined at its ``settled density.'' The Rule 
    requires that manufacturers of dry-applied loose-fill cellulose 
    insulation for attic applications test and disclose the R-value (as 
    well as coverage area and related information) at the long-term, 
    settled density determined according to paragraph 8 of ASTM C 739-91, 
    commonly referred to as the ``Blower Cyclone Shaker'' (``BCS'') 
    test.\45\ Because a consensus-based test procedure had not been adopted 
    for determining the long-term, settled density of dry-applied loose-
    fill mineral-fiber insulation for this type of application, the Rule 
    does not specify the procedure for determining the density of the R-
    value test specimen, but it requires that R-values claimed to consumers 
    be based on long-term thickness and density after settling.\46\
    ---------------------------------------------------------------------------
    
        \45\ Standard Specification for Cellulosic Fiber (Wood-Base) 
    Loose-Fill Thermal Insulation (``ASTM C 739-91'').
        \46\ At the time the Commission promulgated the Rule, GSA had 
    proposed adopting a settled density test procedure for loose-fill 
    mineral fiber insulation products similar to the one it had adopted 
    for loose-fill cellulose insulation products. Mineral fiber 
    manufacturers contended, however, that they took settling into 
    account in their coverage charts, and that if their insulations were 
    installed according to their coverage charts, consumers would 
    receive the R-values they claimed. The Commission imposed a general 
    requirement that R-values of dry-applied loose-fill mineral fiber 
    insulations be based on tests that take the adverse effects of 
    settling into account, but did not specify how the settled density 
    was to be determined. 44 FR at 50228. GSA never adopted a procedure 
    for determining the settled density of mineral fiber insulations.
    ---------------------------------------------------------------------------
    
        Since the Commission promulgated the Rule, new forms of loose-fill-
    type home insulation products have been introduced for use in attic 
    applications, including ``stabilized'' cellulose. ``Stabilized'' 
    cellulose refers to a form of loose-fill cellulose insulation that 
    contains a glue binder and is applied on attic floors with a small 
    amount of liquid. Application of the insulation with the glue binder 
    and liquid purportedly results in lower-density cellulose insulations 
    that do not settle like dry-applied loose-fill cellulose insulations. 
    The Rule does not currently specify a procedure for determining the 
    long-term, settled density of stabilized cellulose insulation.
    
    Comments
    
        Dry-applied Loose-Fill Cellulose. Dr. Wilkes, for ORNL, stated that 
    settling decreases the R-value obtained when a loose-fill insulation 
    product is applied, although limited information exists about the 
    amount of settling that occurs. Dr. Wilkes supported use of the BCS 
    test procedures to determine the settled density of dry-applied loose-
    fill cellulose insulation. He suggested that the BCS procedure may be 
    inappropriate for new products such as those with initial densities as 
    low as 1.0 to 1.5 pounds per cubic foot. For such products, Dr. Wilkes 
    stated that in situ data would be more appropriate than the BCS 
    procedure in determining long-term, settled density, and recommended 
    that the Commission permit manufacturers to submit in-situ data to 
    demonstrate the actual settled density of their products.\47\

        Dry-applied Loose-Fill Mineral Fiber. Eleven comments addressed how 
    the settled density of dry-applied loose-fill mineral fiber insulation 
    products in open attic applications should be determined for R-value 
    testing.\48\ Regal contended that the Rule's objective of creating a 
    level playing field has been compromised because of the failure of GSA, 
    ASTM, and the mineral fiber industry to develop a uniform standard for 
    determining the settled density of dry-applied loose-fill mineral fiber 
    insulations.\49\ Other comments agreed.\50\ Three stated that this 
    uneven playing field (i.e., requiring cellulose manufacturers, but not 
    mineral fiber manufacturers, to use a specific test procedure) imposes 
    a competitive disadvantage for the cellulose industry.\51\ CIMA, for 
    example, stated that the BCS test typically produces 30% settling for 
    loose-fill cellulose, while long-term studies of actual installations 
    rarely find cellulose settling as much as 20%. CIMA asserted that the 
    Rule places the cellulose industry at a competitive disadvantage of as 
    much as 10% to 15% compared to loose-fill fiberglass, and that, if this 
    discrimination has affected the cellulose market share by as little as 
    5%, it has resulted in an annual revenue loss of approximately $50 
    million for cellulose producers.

        Four comments stated this uneven treatment is unfair to 
    consumers.\52\ GreenStone/Smith, for example, stated that mineral fiber 
    manufacturers have not developed a standard test method to measure the 
    settling of loose-fill mineral fiber insulations, but instead claim 
    that if their products are installed at the density they recommend, the 
    amount of settling will be minimal (less than 5%). He asserted that the 
    mineral fiber manufacturers construct coverage charts at this density 
    and represent to consumers that no settling is expected. According to 
    GreenStone/Smith, installers who desire to minimize costs can install 
    loose-fill mineral fiber insulations at less than the density claimed 
    by manufacturers (and at a lower total R-value than claimed), without 
    consumers' knowledge, and thereby save time and material and defraud 
    consumers of the energy savings they anticipate.

        As a short-term solution, five comments recommended that the 
    Commission impose a settlement factor of up to 10% or more for dry-
    applied loose-fill mineral insulation products, pending the adoption of 
    a suitable industry standard to address how much these products 
    settle.\53\ Dr. Yarbrough,

    determining the settled density of stabilized cellulose insulation. Dr. 
    Yarbrough explained that ``stabilized'' cellulose insulation contains a 
    binder, or other means, for bonding particles in the insulation to 
    reduce settling, and that the fan used in the BCS test breaks the bond. 
    Dr. Wilkes and Dr. Yarbrough recommended allowing the use of in situ 
    observations of the degree of settling to establish the settled density 
    at which the R-value of a stabilized cellulose product must be 
    determined. Dr. Yarbrough stated that a methodology for obtaining in 
    situ data is available.\57\ He explained that an ASTM task group is 
    working on a material specification for stabilized cellulose insulation 
    that he expects will include a method for determining settled density, 
    and recommended that the Commission consider requiring the use of the 
    ASTM standard when it has been adopted by ASTM.\58\

        NAIMA recommended requiring that R-value tests on stabilized 
    cellulose insulations be ``done on samples that fully reflect the 
    effect of settling on the product's R-value.'' NAIMA stated that ASTM C 
    1149 \59\ has been modified to include products containing an adhesive 
    that is mixed with water during installation and is intended for use in 
    attic applications. NAIMA stated that a task group is developing a

    Discussion
    
        Dry-applied Loose-fill Cellulose. Although the rule requires 
    manufacturers of dry-applied loose-fill cellulose to determine the R-
    values and coverage of their products at the settled density determined 
    according to the BCS procedure, manufacturers who can demonstrate that 
    the BCS procedure is inappropriate for their products can petition the 
    Commission for an exemption that would allow them to determine the 
    settled density of their products according to a more appropriate 
    methods. See note 30, above.
        Dry-Applied Loose-fill Mineral Fiber. The Rule specifies the 
    procedures to be used in determining the settled density only for 
    cellulosic, and not mineral fiber, insulation products. When the 
    Commission promulgated the Rule in 1979, it expected that GSA soon 
    would adopt a specific test procedure for determining the settled 
    density of dry-applied loose-fill mineral fiber insulation products. 44 
    FR at 50228, 50239 n.239. GSA did not do so, and now accepts the use of 
    ASTM standards, which do not specify procedures for determining the 
    settled density of dry-applied loose-fill mineral fiber insulations.
        Reports of studies conducted by Oak Ridge National Laboratory 
    during the 1980s demonstrate that certain loose-fill mineral fiber 
    insulation products can settle following installation, resulting in a 
    reduction of R-value.\61\The results differed in the amount of 
    settling, and the effect of settling on the R-values of the specific 
    insulation products studied, depending on the type of mineral fiber 
    insulations studied (fiberglass versus rock wool products) due to 
    differences in density.

        The Commission agrees that it would be preferable to specify a 
    uniform procedure for determining the long-term, settled density of 
    dry-applied loose-fill mineral fiber insulation products. 
    Unfortunately, none of the comments suggested a specific procedure that 
    the Commission could adopt at this time. In addition, the comments that 
    suggested requiring an across-the-board settlement factor of 10% have 
    not submitted documentation that would justify the Commission imposing 
    it on all dry-applied loose-fill mineral fiber insulation products.
        The Commission, therefore, solicits comments on specific reliable 
    and uniform procedures that would be appropriate for determining the 
    long-term, settled density of dry-applied loose-fill mineral fiber 
    insulation products, and the submission of data to demonstrate that 
    those procedures will result in uniform and accurate results. For 
    example, the Commission requests any data that demonstrate that any of 
    the following, currently available test procedures, or others, would 
    produce accurate and reliable, long-term settled density results for 
    mineral fiber insulation products in attic applications: the BCS test 
    procedure in ASTM C 739-91 (which currently is required for dry-
    applied, loose-fill cellulose insulation products); the ``Canadian drop 
    box procedure,'' which previously was proposed by GSA for loose-fill 
    mineral fiber insulations under Federal Specification HH-I-1030B; \62\ 
    the British Standard Vibration Test; and the procedure developed in 
    Scandinavia by Dr. Svennerstedt. In the meantime, the Commission will 
    continue to examine the data specific manufacturers use to substantiate 
    their R-value, long-term settled density, and coverage claims.

    ---------------------------------------------------------------------------
    
        Stabilized Cellulose. Because of the manner in which stabilized 
    cellulose insulation is installed, the Commission agrees that the BCS 
    test procedure may not be appropriate for determining its long-term, 
    settled density. Further, the Commission does not believe that the 
    procedure for determining density in ASTM C 1149, which NAIMA 
    suggested, is the appropriate measure of the long-term, settled density 
    of stabilized cellulose insulations installed in attic applications. 
    ASTM C 1149 is designed for insulations sprayed onto walls (most often 
    being applied to metal walls in commercial buildings, where they are 
    left exposed, without being covered by an internal wall), and requires 
    that these insulations be able to support themselves in that type of 
    application. The settling characteristics of stabilized cellulose 
    insulations in attic applications are different from those of self-
    supported insulations sprayed onto walls. ASTM has not yet adopted a 
    specific method for determining the long-term density of stabilized 
    cellulose insulation for attic applications. When ASTM, or others, 
    adopt an appropriate procedure, the Commission will consider whether to 
    require its use. In the meantime, under section 5 of the FTC Act, 
    manufacturers must have a reasonable basis for the density at which 
    they conduct the R-value tests required by the Rule and make R-value 
    claims to consumers.
        Loose-fill and Stabilized Insulations Used in Manufactured Housing 
    Attics. No comments addressed whether the procedures currently used to 
    determine the settled density of dry-applied loose-fill insulations or 
    stabilized insulations when they are used in attics of site-built homes 
    are appropriate for determining
    
    [[Page 48034]]
    
    their settled density when they are used in attics of manufactured 
    housing. Industry members have raised this question separately, 
    however, with the Commission's staff. At issue is whether these 
    insulations, which are installed in attic assemblies in a factory and 
    then transported to the site where the manufactured home will be 
    located, settle more, or differently, than those used in site-built 
    homes because of additional vibrations and other factors during 
    transportation. The Commission solicits comments regarding the extent 
    of settling of dry-applied loose-fill insulations and stabilized 
    insulations when they are used in attics of manufactured housing, the 
    density at which the R-value of these insulations should be determined 
    for use in attics of manufactured housing, and how that density should 
    be determined.
    
    b. Loose-fill and Self-supported Insulations in Walls
    
        Dry-applied loose-fill insulations and spray-applied, self, 
    supported insulations can be installed in walls in residential 
    applications. Dry-applied loose-fill insulations normally can only be 
    applied to existing wall cavities (primarily in retrofit applications). 
    Spray-applied, self-supported insulations can be applied to open wall 
    cavities before installation of internal walls.
        Dry-applied loose-fill insulations may settle when blown into a 
    confined area, such as an enclosed wall cavity, leaving a gap at the 
    top of the wall cavity if they are not sufficiently compressed during 
    installation. Manufacturers who claim an R-value for a dry-applied 
    loose-fill insulation must disclose the R-value at the applied density, 
    determined according to the R-value test procedures specified in the 
    Rule. The Rule, however, does not specify how manufacturers must 
    determine that density because there was no standard procedure for 
    measuring the applied density in wall applications for all products at 
    the time the Commission promulgated the Rule. Because dry-applied 
    loose-fill insulations installed in closed wall cavities must be 
    compressed during application to ensure that they do not settle, the 
    applied density in wall applications is likely to be greater than the 
    settled density of the product when it is installed in an open attic.
        Self-supported, spray-applied insulations, mixed with water and 
    adhesives (also referred to as ``wet-spray'' insulations), are 
    installed pneumatically on-site by professional installers. They may be 
    made of either cellulose or mineral fiber. When applied, this form of 
    insulation requires no support other than the insulation itself or the 
    substrate to which it is attached. These products most often are used 
    in walls in commercial applications, where they may be left exposed 
    after they are installed. They are rarely used in residences, primarily 
    because this application requires the use of more insulation material 
    for a given thickness (i.e. the insulation is installed at a higher 
    density and cost), often without any increase in total R-value, and 
    sometimes at a reduced R-value. They are not used in attics because of 
    their additional weight (and cost). Because these products are applied 
    at a greater density than either dry-applied loose-fill or stabilized 
    insulations, they are not likely to settle. Although this form of 
    insulation was not discussed during the original rulemaking proceeding 
    and the Rule does not specify how R-value these specimens must be 
    prepared, it is covered by the Rule if it is sold for use in the 
    residential market. Because the density at which these insulations are 
    applied affects their R-values, the Commission's staff has advised 
    industry members that they should prepare test specimens according to 
    the manufacturer's installation instructions, using equipment, 
    materials, and procedures representative of the manner in which the 
    insulation is applied in the field.
    
    Comments Regarding the Use of Dry-applied Loose-fill Insulations in 
    Wall Cavities
    
        Two comments recommended requiring the disclosure of R-values and 
    related information for loose-fill insulations intended in walls or 
    other enclosed cavities. NAIMA recommended requiring that coverage 
    charts for these products include R-values maximum net coverage area, 
    and minimum weight per square foot for the thicknesses of common 
    cavities (e.g. 3\1/2\''). NAIMA asserted that separate disclosures for 
    installations of these insulation products in enclosed cavities is 
    necessary to provide guidance about the proper amount of material that 
    must be installed.\63\ Mr. Smith, for GreenStone, agreed and suggested 
    requiring disclosure of a coverage chart for ``Gross Coverage,'' for 
    cavities using 2x4 and 2x6 on 16'' center construction. He recommended 
    requiring the disclosure of the density at which the loose-fill 
    insulation should be installed, along with a statement that 
    applications below this density may be subject to settling and may 
    create gaps at the top of or within wall cavities that may 
    significantly reduce the insulating value of the product. Lastly, he 
    stated that the R-value for each of the wall thicknesses claimed must 
    be determined at the applied density the manufacturer recommends.\64\

    Discussion Regarding the Use of Dry-applied Loose-fill Insulations in 
    Wall Cavities
    
        The Commission agrees that specific requirements for determining 
    the appropriate density for the R-value test specimen and for 
    disclosures on coverage charts for applications in enclosed wall 
    cavities would be appropriate and desirable. GreenStone's suggestion of 
    requiring a statement of ``applied density'' could provide helpful 
    information to installers in determining whether they have installed 
    the requisite amount of insulation material, but it does not address 
    how that density should be determined. The Commission, therefore, 
    solicits comments on whether there are reliable procedures that could 
    be used to determine the density of dry-applied loose-fill insulations 
    when installed in enclosed wall cavities, and the specific disclosures 
    that should be required (e.g., how coverage area for enclosed wall 
    cavities should be described).
    
    Comments Regarding the Use of Self-Supported Insulations in Wall 
    Cavities
    
        ECI recommended adopting the test specimen preparation procedures 
    in ASTM C 1149 when testing insulations that are sprayed into wall 
    cavities.\65\ England recommended requiring use of either HUD UM-80 
    \66\ or ASTM C 1149, both of which apply to spray-applied cellulose 
    insulation, to ensure that R-value and related information is 
    accurate.\67\

    Discussion Regarding the Use of Self-supported Insulations in Wall 
    Cavities
    
        The procedures in paragraph 5.1 of ASTM C 1149-90 and in paragraph 
    9.1.1 of HUD UM-80, which require the R-value test specimens be 
    prepared using the maufacturer's recommended equipment and procedures 
    and at the manufacturer's maximum recommended thickness, appear to be 
    appropriate procedures for preparing R-value test specimens of self-
    supported, spray-applied cellulose insulation products.
    
    [[Page 48035]]
    
    Accordingly, the Commission proposes amending the Rule to require 
    preparation of R-value test specimens of self-supported, spray-applied 
    cellulose insulation products according to either of these 
    specifications. The Commission solicits public comments regarding the 
    accuracy and reliability of the two procedures, whether the Commission 
    should allow use of either procedure or only one, how the Commission 
    should define specifically the products to which the procedures apply, 
    and whether the same procedures (or others) should be required for 
    other types of spray-applied insulations (e.g., mineral fiber 
    insulations) that are used in residential applications.
    
    Discussion Regarding the Use of Loose-fill Insulations and Self-
    supported Insulations in Wall Cavities of Manufactured Housing
    
        No comment addressed whether the procedures currently used to 
    determine the settled density of dry-applied loose-fill insulations or 
    self-supported insulations when they are used in wall cavities of site-
    built homes are appropriate for determining their settled density when 
    they are used in wall cavities of manufactured housing. Industry 
    members have raised this question separately, however, with the 
    Commission's staff. At issue is whether the settling of these 
    insulations, which are installed in wall assemblies in a factory and 
    then transported to the site where the manufactured home will be 
    located, settled more, or differently, than those used in site-built 
    homes because of additional vibrations and other factors during 
    transportation. The Commission solicits comments regarding the extent 
    of settling of dry-applied loose-fill insulations and self-supported 
    insulations when they are used in wall cavities of manufactured 
    housing, the density at which the R-value of these insulations should 
    be determined for use in wall cavities of manufactured housing, and how 
    that density should be determined.
    3. Density Variations
        The Rule's testing and labeling requirements assume that the long-
    term settled density of a dry-applied loose-fill insulation product 
    does not change with variations in thickness. The Rule, therefore, 
    simply requires that manufacturers of dry-applied loose-fill cellulose 
    insulation determine the settled density of each product according to 
    the BCS test procedure and test it for R-value at that density, and 
    that manufacturers of dry-applied loose-fill mineral fiber insulation 
    determine the R-value of each product on samples that fully reflect the 
    effect of settling on R-value. As long as the R-value test has been 
    conducted at that density and at the product's ``representative 
    thickness,'' \68\ the manufacturer can construct the required coverage 
    chart for various total R-value levels based on the R-value result at 
    the tested density.
    ---------------------------------------------------------------------------
    
        \68\ The mathematical extrapolation of R-value for a mass 
    insulation product from thin-sample tests can be misleading because 
    it fails to recognize that, up to at least some thickness, R-value 
    does not increase linearly with increases in thickness. This is 
    referred to as the ``thickness effect.'' To account for the 
    thickness effect, section 460.6 requires that R-value tests of mass 
    insulations be conducted at the product's ``representative 
    thickness,'' which it defines as the thickness at which the R-value 
    per unit will vary no more than plus or minus two percent with 
    increases in thickness. For thicknesses less than the representative 
    thickness, however, the R-value claimed may be based on testing at 
    the claimed thickness. 44 FR at 50226.
    ---------------------------------------------------------------------------
    
    Comments
    
        Ivan Smith, for GreenStone, recommended revising section 460.6 of 
    the Rule to require testing of loose-fill insulations at each thickness 
    shown on a label unless there is a limitation caused by the physical 
    constraints of the test equipment. Mr. Smith believes it is likely that 
    density will be different at each different thickness of loose-fill 
    material, and that this variation of density potentially affects the 
    thickness necessary to obtain the claimed total R-value. He contended 
    that this requirement would not result in a substantial expense to the 
    manufacturer.\69\

        \69\ GreenStone/Smith, #32, at 3.
    ---------------------------------------------------------------------------
    
    Discussion
    
        The Commission cannot determine whether it would be appropriate to 
    propose amending the Rule as Mr. Smith recommended without specific 
    data to demonstrate whether or how much the density of particular types 
    of loose-fill insulations varies with differences in thickness. The 
    Commission solicits comments and data, therefore, on whether, and how 
    much, the density of specific loose-fill insulations varies with 
    thickness, the effect of any such variations on the total R-value at 
    different thickness, and how the Commission should amend the Rule to 
    ensure that R-values and related claims for loose-fill insulation 
    products are accurate.
    4. Installation in Closed Cavities of Variable Thickness
    
    Comments
    
        Dr. Yarbrough, for TN Tech, stated that the evaluation of the 
    thermal performance of insulations used in attics of manufactured 
    housing represents a special challenge because, in some cases, the roof 
    cavity (and the insulation installed in it) varies in thickness and 
    density. For example, these roof cavities often slope to the edge of 
    the roof assembly, where the cavity may be only 1\1/2\'' to 2'' thick. 
    Any insulation (whether it is a batt or blanket, dry-applied loose-
    fill, or stabilized product) installed in such an application can vary 
    in thickness across the cavity, and may be compressed more than normal 
    in the thinnest portions of the cavity. These factors result in 
    different total R-values at different places. Dr. Yarbrough recommended 
    specifying how R-values for such variable thickness and density 
    applications should be calculated, and suggested using a method such as 
    the one he and others have described in a paper published by the 
    American Society of Mechanical Engineers.\70\ He stated that the manner 
    in which R-values are expressed for this type of application could 
    affect a major portion of new manufactured homes and could determine 
    whether insulations installed in these applications achieve the total 
    R-values claimed.\71\

    Discussion
    
        The Commission agrees that it is important to address how R-values 
    should be determined and disclosed to consumers where the insulation 
    varies in thickness and/or density in particular applications, so that 
    R-values claimed to consumers under these circumstances will be 
    accurate and determined according to a uniform standard. The Commission 
    solicits comments, therefore, regarding the method (such as that 
    recommended by Dr. Yarbrough) that should be used to determine and 
    disclose R-values under these circumstances, and how different 
    variables (e.g., thickness, density) should be accounted for in the 
    determination.
    
    D. Other Testing Requirements
    
    1. Accreditation of Testing Laboratories
    
    Comments
    
        The Celotex Corporation recommended requiring that testing 
    laboratories either be accredited by the National Voluntary Laboratory 
    Accreditation Program (``NCLAP''), administered by the U.S. Department 
    of Commerce's National Institute of
    
    [[Page 48036]]
    
    Standards and Technology (``NIST''), for the specific test methods 
    listed in the Rule, or by the International Organization for 
    Standardization (``ISO'') as an ISO/IEC Guide 25 Testing Laboratory. 
    Further, Celotex stated that accreditation as an ISO/IEC Guide 25 
    Laboratory provides global acceptance of a laboratory's test 
    results.\72\
    ---------------------------------------------------------------------------
    
        \72\ Celotex, #25, at 3.
    ---------------------------------------------------------------------------
    
    Discussion
    
        Although accreditation of testing laboratories by a qualified, 
    professional accreditation program generally is useful and important, 
    the Commission is not aware of any significant testing problems with 
    unaccredited laboratories that would justify the Commission's imposing 
    this additional burden under the Rule. Further, to the extent that 
    accreditation of a laboratory provides either domestic or global 
    acceptance of that laboratory's test results, manufacturers and other 
    sellers should already have sufficient incentive to use accredited 
    laboratories, and testing laboratories should have sufficient incentive 
    to seek accreditation, without the Commission imposing an accreditation 
    requirement.
        The Rule already includes several interrelated safeguards to ensure 
    testing integrity that make a separate accreditation requirement 
    unnecessary, absent evidence of testing abuse. First, the Rule requires 
    manufacturers to test or have their products tested to substantiate the 
    R-values they claim, and to maintain specific records concerning the 
    testing methods and results. Second, it enables the Commission to 
    analyze the substantiation tests by evaluating the required testing 
    records. Third, it includes a quality control requirement, under which 
    industry members must ensure that the R-value of the insulation they 
    sell is not more than 10% below the R-value they claim. Thus, even if 
    the manufacturer or other covered party has a test result that purports 
    to verify the claimed R-value, the Commission can obtain samples and 
    conduct its own testing to ensure that accurate, properly determined R-
    values are being disclosed to consumers.
        Although the Commission is not proposing to require laboratory 
    accreditation at this time, it solicits comments on the extent to which 
    manufacturers presently use accredited versus nonaccredited labs. In 
    addition, the Commission seeks comments on whether it should require 
    additional recordkeeping to make the records more clearly demonstrate 
    whether the tests have been conducted accurately and in accordance with 
    the required procedures.
    2. Test Temperature Requirements
        Several test temperature parameters are involved in R-value 
    testing: (1) The temperature on the cold side of the testing apparatus; 
    (2) the temperature on the hot side of the testing apparatus; (3) the 
    mean (or average) test temperature within the test chamber; and (4) the 
    temperature differential (i.e., the temperature spread between the cold 
    and hot sides). The record in the original rulemaking proceeding 
    indicated that variations in these test parameters affected the ASTM 
    steady-state R-value results for mass insulations and reflective 
    insulations differently.
        For mass insulations, the record indicated that R-values decreased 
    as the mean test temperature rose, and that this inverse relationship 
    between R-value and mean test temperature was approximately the same 
    for all mass insulations. On the other hand, the record indicated that 
    variations in the temperature differential between the hot and cold 
    sides did not significantly affect the R-value results. For these 
    reasons and other explained below, the Commission determined the R-
    value tests of mass insulations should be conducted at a mean test 
    temperature of 75  deg.F, but that it was not necessary to specify a 
    required test temperature differential for testing mass insulations.
        For traditional reflective foil insulations, on the other hand, the 
    record indicated that variations in mean test temperature did not 
    affect the R-value results, but that variations in the temperature 
    differential between the hot and cold sides did affect the R-value 
    results. At least at smaller temperature differentials, the record 
    indicated that there was an inverse relationship between R-value and 
    the temperature differential, as the temperature differential 
    increased, the R-value result went down. The Commission determined, 
    therefore, that it was necessary to specify both the mean test 
    temperature and the temperature differential for R-value testing of 
    reflective insulations.
        The R-value of a reflective insulation is related to its 
    emissivity.\73\ Based on evidence that single-sheet reflective foil 
    insulation products with a given emissivity installed in an airspace of 
    the same thickness and configuration will have the same R-value, the 
    Commission minimized manufacturers' testing burdens by allowing them to 
    use the R-values for those products listed in a specific table 
    published by the American Society of Heating, Refrigerating and Air-
    Conditioning Engineers, Inc. (``ASHRAE''). Thus, manufacturers of 
    single-sheet reflective insulation products need only to measure the 
    product's emissivity according to a specific ASTM test procedure (or an 
    alternative procedure that provides comparable results) \74\ and find 
    the appropriate R-value in the ASHRAE table for that emissivity.\75\ 
    The ASHRAE table contained R-values for only certain mean test 
    temperatures and temperature differentials. To ensure that claims were 
    based, to the extent possible, on a standard that would allow 
    comparison on a uniform basis of R-values for single-sheet reflective 
    insulations and mass insulations, the Commission specified that single-
    sheet reflective insulation manufacturers must use the R-value in the 
    ASHRAE table for a mean test temperature of 50  deg.F (the table did 
    not include a mean test temperature of 75  deg.F, so the Commission 
    selected the mean test temperature closest to 75  deg.F) and a 
    temperature differential of 30  deg.F.
    ---------------------------------------------------------------------------
    
        \73\ See note 25, supra.
        \74\ See Part IV.D.5.a.i., infra
        \75\ The values in the table apply only to air spaces of uniform 
    thickness bounded by plane, smooth, parallel surfaces with no 
    leakage of air to or from the space. Further, the table lists only 
    certain emissivities and airspace thicknesses. The Rule specifies 
    that the emissivity must be determined according to ASTM E 408, or 
    another test method that provides comparable results. The R-value of 
    a traditional single-sheet reflective foil insulation product that 
    will be installed in an air space that is not of uniform thickness 
    bounded by plane, smooth, parallel surfaces with no leakage of air 
    to or from the space should be tested according to the Rule's 
    requirements for traditional multi-sheet reflective foil 
    insulations.
    ---------------------------------------------------------------------------
    
        For multi-sheet reflective foil insulations (used to create 
    multiple airspaces), the record indicated that extrapolation of a total 
    R-value from the ASHRAE R-value for a single airspace was unreliable. 
    44 FR at 50228. The Commission, therefore, required that R-values be 
    determined through R-value testing according to specific ASTM 
    procedures. So that the results of these tests would be comparable to 
    those for single-sheet insulations and for mass insulations, the 
    Commission determined that the tests must be conducted at a mean test 
    temperature of 75  deg.F and a temperature differential of 30  deg.F.

    Discussion
    
        The Commission addressed this issue when it originally promulgated 
    the Rule.\77\ To ensure that R-values claimed to consumers are made on 
    a uniform basis, the Commission required that R-values disclosed to 
    consumers be based on steady-state ASTM R-value tests conducted at a 
    mean temperature of 75  deg.F. The Commission concluded that 75  deg.F 
    (which was incorporated in many voluntary industry standards and 
    federal procurement specifications) would be as effective as any other 
    mean temperature in providing a standard mean test temperature for R-
    value comparison purposes, although it otherwise had not particular 
    advantage over any other temperature. By requiring that R-value testing 
    be conducted at this mean test temperature, the Commission did not 
    intend to specify a mean test temperature that would be representative 
    of any particular geographical region, or particular season or of 
    actual performance conditions. Indeed the Commission concluded that 
    requiring sellers to test and disclose R-values at a mean temperature 
    representative of any specific geographical region, or season of the 
    year, would yield R-value results that would be inappropriate for other 
    regions or seasons. Further, it concluded that requiring sellers to 
    test and disclose R-values separately for different regions of seasons 
    would yield multiple disclosures that could confuse consumers and 
    discourage them from using R-values in making purchasing decisions. 
    Thus, the Commission selected a single mean test temperature to 
    establish a uniform standard for disclosing R-values. Although the 
    Commission received no new information that would indicate that any 
    other single mean test temperature would be preferable to 75  deg.F, 
    the Commission invites public comments on this issue, along with 
    comments regarding the testing and the disclosure of in situ 
    performance information. See also the discussion in Part IV.B.1, above.

    ---------------------------------------------------------------------------
    
    b. Temperature Differential
    
    Comments
    
        One comment recommended amending the Rule to specify the 
    temperature differential. NAIMA recommended requiring not only that R-
    value tests be preformed at the mean temperature of 75  deg.F, but also 
    requiring a test temperature differential of ``50  deg.F 10 
     deg.F.'' NAIMA explained that the thermal properties of a specimen may 
    change both with mean temperature and with the temperature difference 
    across the test specimen, and that data and information at standard 
    temperatures are therefore necessary for valid comparison of thermal 
    properties. NAIMA stated that ASTM C 1058 \78\ specifies a temperature 
    difference of 50  deg.F #10  deg.F when conducting tests at 
    a mean temperature of 75  deg.F according to ASTM test methods C 177, C 
    236, C 581, and C 1114.\79\

    ---------------------------------------------------------------------------
    
    Discussion
    
        The Commission agrees that, if current evidence demonstrates that 
    different test temperature differentials affect R-value results, it may 
    be appropriate to consider specifying a test temperature differential 
    in the Rule to ensure the comparability of R-value claims for competing 
    home insulation products. The Commission, therefore, solicits comments 
    on whether, to what extent, and for what types and forms of insulation, 
    variations in the test temperature differential affect R-value results; 
    and what specific test temperature differential(s) the Commission 
    should impose for tests conducted according to each of the R-value test 
    procedures cited in the Rule. See also the discussion in Part IV.B.1, 
    above.
    3. Tolerance
    
    Comments Regarding Responsibilities of Manufacturers Versus Installers
    
        NAIMA \80\ and ICAA \81\ proposed limiting application of the 
    Rule's 10% tolerance limit to manufacturers by replacing the words 
    ``industry member'' with ``manufacturer.''

    ---------------------------------------------------------------------------
    
    Discussion Regarding Responsibilities of Manufacturers Versus 
    Installers
    
        The Commission designed the tolerance limit provision to apply to 
    the manufacturer. Strictly speaking, the tolerance does not apply to 
    professional installers or new home sellers. The Rule requires that 
    professional installers and new home sellers apply loose-fill 
    insulations according to the manufacturer's installation instructions, 
    but allows them to rely on the accuracy of the manufacturer's R-value 
    and installation instructions. Installers and new home sellers 
    therefore have the benefit of the 10% tolerance limit for variances 
    occurring in the manufacturing process. But the tolerance is not 
    intended to allow installers or new home sellers to deviate from the 
    manufacturer's installation instructions. Consequently, the Commission 
    proposes amending the Rule to clarify that the tolerance provision 
    applies solely to claims made by manufacturers.
    
    Comments Regarding How the Tolerance Limit Will Be Applied
    
        NAIMA and Dow suggested clarifying the Rule to state more precisely 
    how the tolerance limit would be applied. NAIMA suggested specifically 
    requiring manufacturers to design their products to 100% of the claimed 
    R-value, rather than aiming at the tolerance. NAIMA further recommended 
    that the section require that the R-value of home insulation to be no 
    more than 5% below the listed R-value for the average of four randomly 
    selected samples, and that the R-value of any single sample to be no 
    more than 10% below the listed R-value. NAIMA explained that limiting 
    the tolerance to the average of four samples would make this section of 
    the Rule consistent with current ASTM material standards. Dow asked 
    that the Commission clarify the intent of Sec. 460.8, and suggested the 
    following language to allow some variability in a production lot 
    (rather than simply permitting an R-value of up to 10% below the 
    claimed value):
    
        The mean R-value of sampled specimens of a production lot must 
    meet or exceed the R-Value shown in a label, fact sheet, ad or other 
    promotional material. No individual specimen can have an R-Value 
    more than 10% below the claimed R-Value.\82\

        \82\ Dow, #37, at 1.
    ---------------------------------------------------------------------------
    
    Discussion Regarding How the Tolerance Limit Will Be Applied
    
        The tolerance limit provision was designed to give manufacturers 
    the flexibility to use the most effective and least burdensome or 
    costly quality control procedures necessary to maintain each product's 
    R-value (and the density necessary to obtain the claimed R-value) 
    within an acceptable limit. At this time, however, the Commission 
    agrees that it would be appropriate to consider whether the Commission 
    should include in the Rule additional, more specific, guidance about 
    how manufacturers should apply the tolerance limit. Possible 
    alternatives include the suggestions made by NAIMA and Dow. 
    Consequently, the
    
    [[Page 48038]]
    
    Commission solicits comments on whether and how it should propose 
    amending the tolerance provision, and the benefits and burdens such an 
    amendment would confer on consumers and insulation sellers.
    
    Comments Regarding Sampling Procedures for the Tolerance Limit
    
        NAIMA recommended amending Sec. 460.8 to require manufacturers to 
    select test specimens in accordance with ASTM C 390-79 \83\ which is 
    the sampling procedure required by all ASTM thermal insulation 
    standards.\84\
    ---------------------------------------------------------------------------
    
        \83\ The current version of this specification is ASTM C 390-79 
    (Reapproved 1995): Standard Criteria for Sampling and Acceptance of 
    Preformed Thermal Insulation Lots (``ASTM C 390-79 (1995)'').
        \84\ NAIMA, #24, at 4.
    ---------------------------------------------------------------------------
    
    Discussion Regarding Sampling Procedures for the Tolerance Limit
    
        In the original rulemaking proceeding, the Commission concluded 
    that the available sampling standards--specifically ASTM C 390 and 
    Military Standard 105 \85\--were not suitable for inclusion as 
    requirements of the Rule because they were extremely complex and were 
    not designed for sampling from a continual production process but, 
    instead, were ``lot'' sampling procedures designed for use in 
    individual transactions. Accordingly, the Commission left the choice of 
    specific sampling methods to the manufacturer's discretion. Likewise, 
    paragraph 3.1.6 of the current ASTM sampling specification, ASTM C 390-
    79 (1995), establishes sampling standards applicable to a specific 
    ``lot'' or ``batch'' (which is defined as ``a definite quantity of some 
    product manufactured under conditions of production that are considered 
    uniform''). Although the Rule does not require specific sampling 
    procedures, it requires that manufacturers be able to prove that test 
    samples they select are representative of ongoing production.
    ---------------------------------------------------------------------------
    
        \85\ The version of the military standard in effect at that time 
    was: Sampling Procedures and Tables for Inspection by Attributes, 
    MIL-STD-105D (``Military Standard 105'').
    ---------------------------------------------------------------------------
    
        To address this issue, the Commission solicits comments on whether 
    manufacturers currently use sampling procedures that do not result in 
    the selection of test specimens that are representative of ongoing 
    production; which specific procedures currently are available for use 
    in sampling from continuing production (or how sampling procedures 
    designed for specific lots could be used to select samples from 
    continuing production); and whether the Commission should require the 
    use of specific sampling procedures.
    4. Use of Current Test Data
    
    Comments
    
        Dr. Yarbrough, for TN Tech, asserted that required R-Value 
    disclosures should be based on test data no more than two years old. He 
    contended that normal quality control activities should require more 
    frequent thermal tests than are currently performed, and that this 
    would not unduly burden the industry. He also recommended that, because 
    the properties of thermal insulation can change when the manufacturing 
    process changes, thermal test data should be based on the current 
    manufacturing process and equipment being used.\86\ Dr. Yarbrough would 
    exclude reflective insulations from this requirement because the 
    thermal measurements for these products are much more expensive than 
    tests for mass insulations. He recommended that a test on a reflective 
    insulation be considered current if it conforms to ASTM C 1224 and the 
    measurements were made on the product being marketed.\87\

    Discussion
    
        When the Commission promulgated the Rule, it considered, but 
    rejected, a recommendation in the Staff Report that the Commission 
    require manufacturers to repeat their R-value substantiation tests 
    every 60 days, coupled with a 5% tolerance limit. The Commission 
    explained that the rulemaking record pointed no single retesting 
    frequency that would be superior for all manufacturers, regardless of 
    the type and amount of insulation they produce and sell and regardless 
    of the variables that might affect the production of each type of 
    insulation product. In addition, the record indicated that there was a 
    limited availability of testing laboratories and testing equipment at 
    that time to conduct the required testing for all manufacturers on a 
    frequent basis.
        Instead, the Commission determined to rely on a tolerance limit 
    provision as the governing quality control mechanism.\88\ It specified 
    10% as the acceptable tolerance limit, and required manufacturers to 
    institute in-plant quality control procedures necessary to stay within 
    that tolerance limit. This mechanism was designed to give manufacturers 
    the flexibility to use whatever quality control procedures are 
    necessary to ensure the accuracy of their R-value claims, using the 
    most effective and efficient, but the least burdensome or costly, means 
    possible within their technical expertise. If the manufacturer changed 
    the raw materials used or the manufacturing process, however, the 
    resulting insulation product would be a new home insulation product. 
    The Rule requires manufacturers to conduct a new R-value test on each 
    new home insulation product, and to disclose the R-value (and related 
    information) of each new product based on the new test.
    ---------------------------------------------------------------------------
    
        \88\ 44 FR at 50229.
    ---------------------------------------------------------------------------
    
        The Commission agrees that it is appropriate to consider whether 
    current conditions would justify the Commission's requiring a more 
    specific retesting quality control mechanism. In this regard, the 
    Commission is interested in comments regarding how frequently 
    manufacturers currently test their insulation products, how much the R-
    value of current production varies,\89\ how frequently manufacturers 
    change their products, whether they retest products that have changed, 
    and what retesting schedule would be most appropriate to ensure the 
    accuracy of R-value claims made to consumers. After considering the 
    comments, the Commission will determine whether it should propose 
    requiring a specific retesting schedule.
    ---------------------------------------------------------------------------
    
        \89\ For example, is the R-value of the insulation being 
    produced consistently below the R-value claimed and previously 
    determined, even if it is within the Rule's 10% tolerance?
    ---------------------------------------------------------------------------
    
    5. Determining the Thermal Performance of Reflective Insulations
        Two basic forms of reflective insulation products are marketed for 
    use in the residential market: (1) Traditional single-sheet and multi-
    sheet reflective insulations; and (2) single-sheet radiant barrier 
    reflective insulations. Traditional reflective insulation products 
    normally are installed in closed cavities, such as walls. As explained 
    in Part IV.D.2, above, the Rule requires that manufacturers of 
    traditional reflective insulation products use specific test procedures 
    to determine the R-values of their products, and that manufacturers and 
    other sellers disclose R-values to consumers for specific applications.
        Radiant barrier reflective insulations, on the other hand, are 
    installed in attics facing the attic's open airspace. Although radiant 
    barrier reflective insulations are covered by the R-value Rule, R-value 
    claims are not appropriate for them because no generally accepted test 
    procedure exists to determine the R-value of a radiant barrier 
    reflective insulation in an open attic. Sellers who make energy savings 
    claims for radiant barrier insulations, however, must have
    
    [[Page 48039]]
    
    a reasonable basis for the claims under Section 460.19(a) of the Rule.

    Comments
    
        Three comments recommended allowing the use of updated or 
    alternative test procedures to measure the emissivity of traditional 
    single-sheet reflective insulations.\90\ Celotex and PIMA \91\ 
    recommended requiring that emissivity be determined under ASTM E 408-71 
    (1990),\92\ ASTM C 835-82 (1988),\93\ or another method that provides 
    comparable results. Dr. Wilkes, for ORNL, reported that ASTM is in the 
    final stages of developing a procedure to measure the emittance of foil 
    sheets with a portable Emissometer, and recommended that the Commission 
    include this procedure in section 460.5(c) when ASTM adopts it.\94\

    Wilkes recommended Dr. Wilkes informed the Commission's staff that the 
    procedure is a very simple, quick measurement, using an instrument that 
    costs about $1,000. He also informed the staff that, while there is no 
    meaningful statistical difference between the results of measurements 
    under ASTM C 1371-97 and ASTM C 835-95, the ASTM C 835-95 procedure is 
    considerably more complicated.

        The Commission solicits comments on the accuracy, reliability, and 
    consistency of each of these procedures in measuring emissivity; the 
    costs of conducting the procedures; and whether the Commission should 
    require the emissivity be measured by only one procedure to ensure that 
    measurements of emissivity are accurate and reliable.
    
    ii. Multi-sheet Products
    
    Comments
    
        The five comments that addressed the Rule's R-value testing 
    requirements for traditional multi-sheet reflective foil insulations 
    recommended requiring that R-values be determined according to the 
    procedures specified in ASTM C 1224-93, either in addition to or 
    instead of the two ASTM R-value test procedures specified in the 
    Rule.\96\ Dr. Wilkes, for ORNL, explained that ASTM C 1224-93 requires 
    R-value testing according to ASTM C 236 or ASTM C 976, but specifies 
    additional instrumentation for the tests and a method of calculating R-
    values based on the R-value test procedure measurements. He further 
    recommended requiring that the tests be conducted at the mean test 
    temperature and temperature differential specified in ASTM C 1224-
    93.\97\
    ---------------------------------------------------------------------------
    
        \96\ NAIMA, #24, at 3 (ASTM C 1224-93 was not developed when the 
    Rule was issued; reference in the Rule to C 236 and C 976 is 
    unnecessary because those standards are incorporated into C 1224); 
    Celotex, #25, at 4; TN Tech, #26, at 3; ORNL/Wilkes, #29, at 6; 
    PIMA, #30, at 6.
        \97\ ORNL/Wilkes, #29, at 6. ASTM C 1224-93 requires testing at 
    a cavity mean test temperature of 754  deg.F 
    (242  deg.C) with a temperature difference across the 
    insulated cavity of 302  deg.F (16.51 
    deg.C). These temperature requirements are similar to those 
    currently required by the Rule, but ASTM C 1224-93 specifies that 
    the temperatures are those within the cavity (not including the 
    cavity walls, or the air temperatures inside or outside the house) 
    and incorporates tolerances to allow minor temperature variations.
    ---------------------------------------------------------------------------
    
    Discussion
    
        Traditional multi-sheet reflective insulations must be tested in an 
    enclosed cavity system that includes air spaces. Testing such a system 
    requires the construction of a test panel to contain the reflective 
    insulation. R-values determined in these systems tests may vary 
    depending on the size and configuration of the test panel, the 
    materials used to construct the test panel, how mean temperature and 
    temperature differential are measured, and the corrections for 
    components such as framing members used in the test panel that are made 
    in the calculation of R-values based on the test results. ASTM C 1224-
    93 includes requirements concerning the construction of the test panel, 
    verification of the R-value measurement, and calculation of the R-value 
    of the reflective insulation from the R-value measurement of the entire 
    system. The Commission concludes that requiring standardization of 
    these variables would be comparable to the Rule's requirements that 
    test specimens of certain mass insulation products be prepared 
    according to specified procedures and that R-values determined under 
    ASTM C 177-85 (1993) or ASTM C 518-91 be reported in accordance with 
    the requirements of ASTM C 1045-90, and would benefit consumers by 
    making R-value claims for these products more accurate and reliable.
        For these reasons, the Commission proposes requiring that R-values 
    for reflective insulations be tested according to ASTM C 236-89 (1993) 
    or ASTM C 976-90 in a test panel constructed according to ASTM C 1224-
    93, and under the test conditions specified in ASTM C 1224-93, and that 
    the R-values be calculated according to the formula specified in ASTM C 
    1224-93, from the results of those R-value tests. The Commission 
    solicits comments on this proposal.
    
    b. Radiant Barrier Products
    
    Comments
    
        Dr. Wilkes, for ORNL, states that ASTM is developing a method for 
    evaluating the thermal performance of low-emittance foils used in 
    residential attics to reduce radiative transport across the attic air 
    space. He recommended that the Commission incorporate this method into 
    the Rule once ASTM adopts it.\98\

    Discussion
    
        ASTM has now adopted the standard referred to by Dr. Wilkes. The 
    standard, ASTM C 1340-96,\99\ incorporates a complicated calculation 
    (and computer program) to determine the heat flux through an attic 
    containing a radiant barrier. The results do not determine an R-value 
    rating, but instead a performance value that might serve as a 
    reasonable basis for energy savings claims (and related performance 
    claims) made about radiant barrier insulations. The Commission solicits 
    comments concerning the specific type of performance the standard 
    measures, how the standard may be used to substantiate energy savings 
    claims or other performance claims for radiant barrier insulations, the 
    types of installations of radiant barrier insulations for which the 
    standard may be used, the accuracy of the determinations made under the 
    standard, and whether the Commission should require that energy savings 
    or other performance claims for radiant
    
    [[Page 48040]]
    
    barrier insulations be based on the standard.

    6. Additional Laboratory Procedures for Testing Loose-fill Insulations
    
    Comments
    
        NAIMA recommended that the Commission require testing of loose-fill 
    insulations ``in full conformance with ASTM C 687-93.'' \100\ NAIMA 
    explained that C 687 has been significantly improved since the Rule 
    became effective and that it now deals more specifically with test 
    specimen preparation techniques, stabilization times, and measurement 
    of the specimen density in the test area, resulting in a significant 
    improvement in test precision.\101\
    ---------------------------------------------------------------------------

    Determination of Thermal Resistance of Loose-fill Building 
    Insulation (``ASTM C 687-95'').

    ---------------------------------------------------------------------------
    
    Discussion
    
        ASTM C 687-95 (the current ASTM specification) is a standard 
    practice, rather than a test procedure. It specifies procedures to be 
    followed in testing a variety of loose-fill insulations to be used in 
    other than enclosed applications. It is a detailed laboratory 
    procedures guide that appears to be both comprehensive and complicated. 
    In an attempt to minimize burdens imposed by the rule, the Commission 
    limited its testing requirements to the minimums necessary to ensure 
    the accuracy and reliability of test results. The Rule, therefore, 
    specifies only the basic R-value test procedures and test specimen 
    preparation procedures for certain products that are necessary to 
    account for factors that can significantly affect R-value results 
    (e.g., aging, settling). In the original rulemaking proceeding, the 
    Commission considered, but rejected as unnecessary, requiring adherence 
    to more detailed standard practice or standard guide specifications, 
    such as ASTM C 687. Without data substantiating the need to specify 
    detailed laboratory operating procedures, for these insulations or 
    others, the Commission is reluctant to consider imposing additional 
    requirements. The Commission invites public comments, however, on 
    whether and why there is a need to specify in more detail the 
    laboratory procedures that should be followed in preparing test 
    specimens and conducting R-value test procedures, for loose-fill 
    insulations as well as other forms of insulations, and the benefits and 
    burdens from such additional requirements.
    
    E. Other Disclosure Issues
    
    1. Disclosures on Labels and Fact Sheets
    
    a. ``What You Should Know About R-values''
    
    Comments
    
        The Rule requires the manufacturer's fact sheet to include a 
    specific statement entitled ``What You Should Know About R-values'' 
    that explains the meaning of R-value and lists factors consumers should 
    consider when purchasing insulation.\102\ Regal suggested that this 
    statement should be more specific in explaining how consumers can 
    determine the amount of insulation they need. Regal commended the 
    Insulation Fact Sheet published by the DOE for providing the best such 
    information for consumers, but contended that it is not readily 
    available in the marketplace. Regal also explained that the DOE ZIP 
    Computer Program can be used to make a cost-benefit analysis for 
    specific insulation products based on their cost per R-value and 
    expected benefits.\103\
    ---------------------------------------------------------------------------
    
        \102\ The required statement is:
        READ THIS BEFORE YOU BUY
        What You Should Know About R-values.
        The chart shows the R-value of this insulation, R means 
    resistance to heat flow. The higher the R-value, the greater the 
    insulating power. Compare insulation R-values before you buy.
        There are other factors to consider. The amount of insulation 
    you need depends mainly on the climate you live in. Also, your fuel 
    savings from insulation will depend upon the climate, the type and 
    size of your house, the amount of insulation already in your house, 
    and your fuel use patterns and family size. If you buy too much 
    insulation, it will cost you more than what you'll save on fuel.
        To get the marked R-value, it is essential that this insulation 
    be installed properly.
        \103\ Regal, #16, at 2-3.
    ---------------------------------------------------------------------------
    
        Corbond suggested that the current Rule has four negative effects 
    that the Commission should address: (1) The Rule codifies the least 
    effective measure of insulation performance, conductivity, as the sole 
    measure widely used for comparing insulation value; (2) the Rule's 
    emphasis on a product's R-value, as opposed to factors that affect 
    installed performance, retards the development and acceptance of new 
    products that perform better than fiberglass insulations because their 
    performance appears the same when measured by R-value alone; (3) energy 
    codes that require the installation of specific R-values favor products 
    such as fiberglass insulations because the code requirements do not 
    recognize the superior performance of insulations that are not subject 
    to degradation of R-value in actual use due to factors such as venting, 
    wind, convection, and moisture accumulation; and (4) the Rule 
    perpetuates the use of an obsolete product, fiberglass insulation, 
    which requires supplementation by other products and techniques (e.g., 
    foam caulk, house-wrap, sheet vapor barriers, foam insulation 
    sheathing, and venting) to help it do the job it should be able to do 
    on its own.\104\
    ---------------------------------------------------------------------------
    
        \104\ Carbond, #41, at 1-2.
    ---------------------------------------------------------------------------
    
        CIMA and Corbond recommended that the Commission add language to 
    the required statement to address these concerns. CIMA recommended the 
    following statement: \105\
    ---------------------------------------------------------------------------
    
        \105\ CIMA, #19, 4-5.
    
        R-value is important, but it is only one of many factors that 
    affect the actual performance of insulation as installed. Other 
    important factors to consider include air permeability, ability of 
    the insulation to ``tighten'' the building against air infiltration, 
    susceptibility to convective heat loss under cold conditions, and 
    ---------------------------------------------------------------------------
    proper installation.
    
        Corbond supported CIMA's suggestion, but recommended the use of an 
    expanded version of the statement:
    
        R-value is important, but it is only one of the many factors 
    that affect the actual performance of insulation as installed. Other 
    important factors to consider include air permeability, ability of 
    the insulation to ``tighten'' the building against air infiltration, 
    susceptibility to convective heat loss under cold conditions, the 
    potential for moisture permeation and accumulation and its 
    deteriorating effects, and proper installation. Consult your 
    insulation manufacturer for information regarding the true 
    performance efficiency of the insulation under conditions 
    appropriate to your climate.
    
    Discussion
    
        The original purpose of the required explanation in fact sheets was 
    to minimize disclosure burdens on industry members who advertise energy 
    or fuel savings. Instead of requiring them to provide lengthy 
    disclosures in ads that claim energy savings, the ad simply could refer 
    consumers to information in the manufacturer's fact sheet.\106\ This 
    approach would ensure that the explanatory information would be made 
    available to consumers, while keeping advertisements less cluttered.
    ---------------------------------------------------------------------------
    
        \106\ 44 FR at 50233-34.
    ---------------------------------------------------------------------------
    
        The Commission recognizes that, as the comments have indicated, 
    more information could be provided in the explanation about how 
    consumers can purchase the most cost-effective amount of insulation, 
    and that there are additional factors that can affect R-value and 
    performance in actual use. The Commission drafted the statement to 
    balance consumers' need for information against keeping the statement 
    simple enough to be useful and not detract from its basic purpose--
    making consumers aware that there are
    
    [[Page 48041]]
    
    various factors they should consider when purchasing products to make 
    their homes more energy efficient.
        Because new information may be available about the factors that 
    affect insulation performance, the Commission is willing to consider 
    revising the explanation. The Commission is concerned, however, that 
    many consumers would not understand the meaning or impact of a general 
    cautionary statement that contains terms such as ``air permeability,'' 
    ``susceptibility to convective heat loss under cold conditions,'' ``the 
    potential for moisture permeation and accumulation and its 
    deteriorating effects.'' The Commission, therefore, solicits comments 
    regarding how the explanation could be revised to provide the most 
    useful information to assist consumers in making purchasing decisions. 
    In particular, the Commission is interested in receiving information 
    about the factors that should be included, why those factors are 
    important, how the information could be explained in a meaningful and 
    helpful manner, and how the information would assist consumers in 
    making purchasing decisions. Among other things, commenters are 
    requested to include data such as consumer perception studies that 
    demonstrate whether suggested alternative disclosures would be 
    meaningful to consumers.
    
    b. Disclosures for Batt, Blanket, and Boardstock Insulations
    
        Subsections 460.12(b)(1) and 460.12(B)(4) of the Rule require that 
    manufacturers label all packages of batt/blanket insulations and 
    boardstock insulations, respectively, with a chart showing the R-value, 
    length, width, thickness, and square feet of insulation in the package, 
    and 460.13(c)(1) requires that they include the chart on the 
    manufacturer's fact sheets.
    
    Comments Regarding Batt and Blanket Insulations
    
        NAIMA recommended amending 460.12(b)(1) to apply to all batt and 
    blanket insulation products by deleting the reference to ``mineral 
    fiber.'' NAIMA asserted that batts and blankets made of other 
    materials, such as cotton, other cellulosic materials, and plastic 
    fiber, have been introduced into the marketplace and that the Rule 
    should specify labeling requirements for these new batt and blanket 
    products.\107\
    ---------------------------------------------------------------------------
    
        \107\ NAIMA, #24, at 4.
    ---------------------------------------------------------------------------
    
    Discussion Regarding Batt and Blanket Insulations
    
        The Commission agrees that all types of batt and blanket 
    insulations should be labeled with the same basic R-value and coverage 
    area information, and that manufactures' fact sheets for these 
    insulation products should include these disclosures. Like other basic 
    coverage chart disclosure requirements in section 460.12(b), the 
    Commission designed this coverage chart disclosure requirement to apply 
    to the form of the product (batt or blanket), not the type (e.g., 
    mineral fiber). The Rule refers to ``mineral fiber'' batts and blankets 
    because when the Rule was promulgated the batt and blanket insulation 
    products being sold in the residential market were mineral fiber 
    insulation products, primarily fiberglass. The Commission, therefore, 
    proposes amending the Rule to clarify the requirement by deleting the 
    phrase ``mineral fiber'' from section 460.12(b)(1), and solicits 
    comments on this proposal.
    
    Comments Regarding Disclosures to Assist Installers and Post-
    Installation Inspectors
    
        ICAA recommended that the Commission require manufacturers of batt 
    and blanket insulations to mark their products with the R-value in 
    numerical terms only. ICAA contended that the method some manufacturers 
    use of applying stripes on unfaced batt and blanket products to 
    indicate the product's R-value is not understood by installers, code 
    compliance officials, and others in the building inspection 
    community.\108\
    ---------------------------------------------------------------------------
    
        \108\ ICAA/1, #17, at 3. ICAA provided an article from 
    Insulation Contractors Monthly (Appendix A to the comment) 
    describing guidelines, issued by NAIMA, for identifying, by means of 
    stripes, the R-values of unfaced fiberglass insulation. See also 
    NAIMA, #24m at 6-7.
    ---------------------------------------------------------------------------
    
        To assist building code officials and others who perform post-
    installation inspections in determining whether the correct R-value has 
    been installed, ICAA also recommended that the Commission require 
    manufacturers of unfaced batt and blanket insulation products to 
    include the following statement on their product packages:
        The unfaced batt should be installed so that the R-value 
    identification is visible for inspection. ICAA reported that the 1955 
    version of the Model Energy Code (``CABO/MEC''), issued by the Council 
    of American Building Officials (``CABO''), recommends that insulation 
    be installed in a manner that will permit inspection of the 
    manufacturer's R-value identification mark. ICAA asserted that that is 
    important that contractors who install unfaced batts and blanket do so 
    in a way that will make it possible to verify R-value quickly and 
    easily.\109\

    Discussion Regarding Disclosures To Assist Installers and Post-
    Installation Inspectors
    
        The R-value Rule does not require that individual pieces of 
    insulation be marked, but instead requires point-of-sale disclosures to 
    consumers prior to purchase on manufacturers' package labels and fact 
    sheets, and on receipts or contracts professional installers and new 
    home sellers must give to consumers. These prepurchase disclosures 
    enable consumers to compare competing insulation products and make 
    purchasing decisions. As ICAA's comment suggests, however, many 
    manufacturers also mark individual insulation products such as faced or 
    unfaced batts and blankets and boardstock products in some way to 
    identify their R-value.
        Under provisions of the Energy Policy and Conservation Act of 1992, 
    DOE, the U.S. Department of Housing and Urban Development (``HUD''), 
    and the U.S. Department of Agriculture (``USDA'') have adopted the 
    CABO/MEC for federal residential buildings or federally insured 
    residential housing, and 33 states have adopted, at some level, some 
    version of the CABO/MEC, or its equivalent. The CABO/MEC (including the 
    1995 version) requires for new residential construction (including new 
    additions to existing residential buildings), that, among other things: 
    (1) An R-value identification mark appear on each piece of insulation 
    that is 12 inches wide or greater; and (2) individual pieces of 
    insulation be installed in attics, floors, and wall cavities in a 
    manner that permits post-installation inspection of the manufacturer's 
    R-value identification mark. These requirements assist building 
    inspectors in determining, after installation, whether the proper 
    amount of insulation has been installed to meet the minimum thermal 
    performance requirements of the CABO/MEC.
        Marking individual batt, blanket, and boardstock insulation 
    products with R-values would not provide additional prepurchase 
    information to consumers (beyond the required disclosures on product 
    packages, manufacturers' fact sheets, and in contracts or receipts). It 
    would, however, facilitate R-value verification. But, the CABO/MEC 
    already requires such marking and it has
    
    [[Page 48042]]
    
    been adopted for new residential construction by other agencies of the 
    federal government and the majority of states. Thus, it does not appear 
    necessary for the Commission to amend the Rule to require that 
    individual batts, blankets, or other insulation products be marked. The 
    Commission solicits comments, however, regarding whether this 
    additional disclosure requirement in the Rule would assist consumers in 
    making purchasing decisions, whether (and why) CABO/MEC requirements 
    are insufficient to provide this information to building inspectors, 
    and whether (and to what extent) there currently are abuses in the sale 
    and installation of home insulation that could be remedied by 
    duplicating the CABO/MEC requirements in the R-value Rule, as well as 
    the costs that such an amendment would impose on manufacturers.
    
    Comments Regarding Disclosure of Thickness
    
        Celotex and PIMA recommended requiring the disclosure, on the 
    required coverage charts on manufacturer's package labels and fact 
    sheets for boardstock insulations, of the ``nominal thickness'' of the 
    boards in the package. The comments asserted that boardstock 
    insulations are produced in nominal (or average) thicknesses and 
    expressed concern that the current wording of the section implies exact 
    thickness.\110\
    ---------------------------------------------------------------------------
    
        \110\ Celotex, #25, at 5; PIMA, #30, at 7. The Commission 
    understands that, by ``nominal thickness,'' the comments mean the 
    ``average thickness'' of each board.
    ---------------------------------------------------------------------------
    
    Discussion Regarding Disclosure of Thickness
    
        Subsections 460.12(b)(1) and 460.12(b)(4) of the Rule require the 
    disclosure of ``thickness'' for batts, blankets, and boardstock 
    products, without defining whether the thickness disclosed must be the 
    actual, minimum, nominal, or average thickness.\111\ Although 
    variations in the manufacturing process may make it difficult for 
    manufacturers to ensure that they produce products of exact thickness, 
    it is essential that the thickness delivered to consumers be within a 
    reasonable tolerance because the total R-value of a batt, blanket or 
    boardstock insulation product is directly related to its thickness. In 
    order to provide guidance to sellers, the Commission solicits comments 
    on: (1) Whether it should propose amending the Rule to specify 
    individual tolerances for the required thickness disclosure (as well as 
    required disclosures of net weight and other dimensions of packaged 
    insulation products) and procedures for determining whether products 
    are within those tolerances; (2) what tolerances and procedures it 
    should consider, for example, the procedures and tolerances adopted by 
    the National Conference of Weights and Measures (``NCMW'');\112\ and 
    (3) the benefits and burdens to consumers and sellers of specifying 
    individual tolerances and procedures for these measurements.
    ---------------------------------------------------------------------------
    
        \111\ The Commission, on the other hand, required the disclosure 
    of ``minimum thickness'' for loose-fill insulations in subsections 
    460.12(b)(2)-(3) to address the issue of settling, which is 
    discussed supra.
        \112\ See ``Checking the Net Contents of Packaged Goods,'' NBS/
    NIST Handbook 133, Third Edition (including Supplements 1, 2, and 3) 
    (Sept. 1998), and ``Checking the Net Contents of Packaged Goods,'' 
    NIST Handbook 133, Third Edition, Supplement 4 (Oct. 1994). The NCWM 
    procedures provide mean and maximum allowable variations for the net 
    contents of packaged items, including weight, dimensions, and other 
    measurements.
    ---------------------------------------------------------------------------
    
    c. Disclosures for Loose-fill Insulations
    
        Section 460.12(b) of the rule requires that labels on loose-fill 
    insulation packages disclose the minimum net weight of the insulation 
    in the package and include a coverage chart disclosing minimum 
    thickness (after settling), maximum net coverage area, minimum weight 
    per square foot, and (for loose-fill cellulose insulation only) number 
    of bags per 1,000 square feet for each of several specified total R-
    values for installation in open attics. The Rule currently specifies 
    different total R-values for which the disclosures must be made for 
    loose-fill cellulose insulations and other types of loose-fill 
    insulations. The rule requires professional installers to calculate the 
    number of square feet to be insulated and to install the number of bags 
    indicated on the manufacturer's coverage chart that are necessary for 
    the desired R-value (commonly referred to as ``bag count'').
    
    Comments Regarding Required Disclosures
    
        Four comments recommended that the Commission amend section 
    460.12(b) to require the same total R-value and other disclosures for 
    all types of loose-fill insulations.\113\

    ---------------------------------------------------------------------------
    
    Discussion Regarding Required Disclosures
    
        The Commission agrees that it would be appropriate to require the 
    same disclosures for all types of loose-fill insulations for 
    application in attics or other open areas. The Commission originally 
    prescribed separate disclosure requirements for loose-fill cellulose 
    insulations and other types of loose-fill insulations (primarily 
    material fiber loose-fill insulations) in response to requests that the 
    Rule, where possible, apply labeling requirements consistent with GSA's 
    purchasing specifications. 44 FR at 50230. GSA's specifications at that 
    time required that labels for loose-fill cellulose insulation disclose 
    the number of bags required to cover 1,000 square feet, but did not 
    require this disclosure on labels for loose-fill mineral fiber 
    insulation, and it required that the mandatory disclosures be made at 
    different total R-values for the two types of loose-fill 
    insulations.114 After the Commission promulgated the Rule, 
    GSA eliminated its own specifications and now uses ASTM material 
    specifications for determining which insulation products may be 
    purchased by the federal government (or in connection with programs 
    operated by the federal government).115 The Commission 
    believes that there no longer is any justification for requiring 
    different disclosures for different types of loose-fill insulations for 
    application in attics or other open areas, and proposes to apply a 
    single set of disclosures requirements for all types. The Commission 
    solicits comments regarding this proposal, including the total R-values 
    for which it would be most appropriate to require the disclosures, and 
    whether the same disclosures should apply to both dry-applied loose-
    fill insulations and stabilized insulations.
    ---------------------------------------------------------------------------
    
        \114\ Consistent with the GSA specification, subsection 
    460.12(b)(2) requires that the disclosures be made at R-values of 
    11, 19, and 22 and all loose-fill insulation except cellulose, and 
    subsection 460.12(b)(3) requires the disclosures at R-values of 13, 
    19, 24, 32, and 40 for loose-file cellulose insulation.
        \115\ In its compliance guidelines published in 1980, the 
    Commission's staff explained that GSA had eliminated its own 
    specifications and recommended that manufacturers of mineral fiber 
    and other loose-file insulations other than cellulose include a 
    column disclosing number of bags per 1,000 square feet in their 
    coverage charts. Staff compliance guidelines, 45 FR 68920, at 68923-
    24 (1980). The Commission believes that virtually all manufacturers 
    of loose-file insulation currently includes this information.

    Comments Regarding Disclosure of ``Minimum Net Weight''

    Discussion Regarding Disclosure of ``Minimum Net Weight''
    
        Subsections 460.12(b)(2) and 460.12(b)(3) require that ``minimum 
    net weight'' be disclosed on package labels of all types of loose-fill 
    insulations, but do not require all the disclosure be made in those 
    exact words. Some state weights and measures regulations, on the other 
    hand, require the disclosure of ``net weight'' or ``nominal net 
    weight,'' using specific words. To ensure that manufacturers and other 
    sellers can conform to the requirements of both the Rule and the 
    states' regulations, the Commission's staff had advised home insulation 
    manufacturers that the Rule does not require that the word ``minimum'' 
    appear in the disclosure, and that they can use the terms required by 
    the state regulations. The Commission affirms the staff's advice.
        Further, the Commission intended the term ``minimum net weight'' in 
    the Rule to mean that the package contains at least the weight claimed, 
    because the accuracy of the information in the coverage chart depends 
    on the package containing that amount of insulation material. Terms 
    such as ``net weight'' or ``nominal net weight'' in state weights and 
    measures regulations, on the other hand, have been interpreted to mean 
    average weight per package, within a specific tolerance, over a given 
    lot of packages or production runs. As with the thickness of batt, 
    blanket, and boardstock insulations, discussed in Part IV.E.1.b, above 
    variations in the manufacturing process may make it difficult for 
    manufacturers to ensure that they produce loose-fill insulation 
    packages filled with an exact weight of material; but it is essential 
    that sufficient loose-fill insulation material be installed for 
    consumers to received the total R-value they are purchasing. If an 
    insufficient amount of material is contained in the packages used to 
    install insulation in a particular consumer's home, even if the average 
    weight is correct over the sampling lot considered, that consumer will 
    receive less insulation R-value than promised.
        The Commission is committed to ensuring that consumers receive what 
    they are promised, while also minimizing unnecessary burdens and costs 
    on sellers. The Commission, therefore, solicits comments on: (1) 
    Whether it should propose amending the Rule to specify individual 
    tolerances for the required net weight disclosure for loose-fill 
    insulation and procedures for determining whether packages are within 
    those tolerances; (2) what tolerances and procedures it should 
    consider, for example, the tolerances and procedures adopted by the 
    NCWN;117 and (3) the benefits and burdens to consumers and 
    sellers of specifying individual tolerances and procedures for the 
    measurement of net weight.

    Comments Regarding Disclosure of ``Minimum Thickness''
    
        Seven comments discussed issues relating to the requirement in 
    subsections 460.12(b)(2)-(3) that labels include a coverage chart 
    disclosing, among other information, the ``minimum thickness'' \118\ of 
    loose-fill insulations for application in attics and other open 
    areas.\119\ ICAA proposed that the Commission amend the Rule to require 
    that manufacturers of loose-fill cellulose insulations disclose 
    ``minimum initially installed thickness'' in addition to ``minimum 
    thickness.'' ICAA contended that this additional information would 
    assist installers by preventing them from mistakenly initially 
    installing loose fill cellulose insulation only to the ``minimum 
    thickness'' currently shown on the coverage chart (that is, the minimum 
    thickness required to obtain the claimed total R-value after the 
    product has settled). ICAA believes that is a long-standing industry 
    practice that violates the Rule. ICAA asserted that CIMA agrees that 
    this additional information would result in a marked improvement in 
    consumer protection. ICAA contended that manufacturers' failure to 
    provide this information on coverage charts effectively results in the 
    installation of loose-fill insulation at total R-values below what is 
    claimed.\116\
    ---------------------------------------------------------------------------
    
        \118\ The term ``minimum thickness'' in subsections 
    460.12(b)(2)-(3) refers to the thickness of installed loose-fill 
    insulation after settling, not to the thickness of a packaged 
    product. The discussion in the text of tolerances and procedures for 
    measuring the thickness of packaged products, therefore, does not 
    apply to the discussion of ``minimum thickness'' in subsections 
    460.12(b)(2)-(3).

    ---------------------------------------------------------------------------
    
        NAIMA supported ICAA's proposal and recommended requiring 
    disclosures on coverage charts of the ``minimum initial installed 
    thickness,'' in addition to ``minimum settled thickness,'' for products 
    that settle enough to reduce the total R-value by more than five 
    percent. NAIMA reported that ICAA has requested that loose-fill 
    cellulose insulation manufacturers include ``initial installed 
    thickness'' disclosures on coverage charts, that several manufacturers 
    currently put this information on their coverage charts, and that ASTM 
    has developed a test method to determine initial installed thickness to 
    support ICAA's initiative.\117\ Mr. Smith, for GreenStone, similarly 
    recommended requiring the disclosure of both ``minimum settled 
    thickness' and ``approximate initial installed thickness'' on coverage 
    charts of loose-fill insulations.\118\
    ---------------------------------------------------------------------------
    
        \117\ NAIMA, #24, at 5. NAIMA stated that the ASTM C 16 
    committee has developed a test method to determine initial installed 
    thickness, and that ASTM C 16.23 has developed a draft standard 
    guide for development of coverage charts for loose-fill insulation 
    that includes the initial installed thickness language NAIMA 
    recommended

    ---------------------------------------------------------------------------
    
        Two comments specifically opposed requiring the disclosure of 
    initial installed thickness. Hamilton contended that it is very 
    difficult to arrive at a single thickness that will apply to all 
    installation blowing equipment and installers' application techniques, 
    and suggested that manufacturers should place more emphasis on training 
    and instructions for professional installers instead of emphasizing an 
    initially installed thickness.\119\ Clayville commented that the issue 
    of disclosing an initial installed thickness has been raised primarily 
    by ICAA, whose members installed predominantly mineral fiber 
    insulation, and that the proposal appears calculated to take advantage 
    of the lack of a recognized test procedure to determine the settlement 
    of (dry-applied) loose-fill mineral fiber insulations after 
    installation. Clayville contended that requiring the addition of an 
    initial installed thickness column would create even more confusion in 
    the industry and would not benefit consumers.\120\

        Tascon stated that the thickness of loose-fill insulation does not 
    accurately determine its total R-value because there are different 
    types of installation equipment and application techniques, including 
    some that deliberately ``fluff'' (dry-applied) loose-fill insulation 
    products; that is, that increase a product's thickness (by applying it 
    with more air at a lower density) at the expense of its density and 
    total R-value. Tascon recommended that the Commission continue to 
    emphasize bag
    
    [[Page 48044]]
    
    account to ensure that installers apply the necessary amount of loose-
    fill insulation in attics to attain the desired total R-value.\121\

    ---------------------------------------------------------------------------
    
        As an alternative to disclosing minimum installed thickness for 
    their products, several manufacturers now guarantee that the installer 
    will attain the claimed total R-value (and the weight per square foot 
    and density necessary for that R-value) by initially applying at least 
    a specific ``guaranteed thickness.'' ICAA proposed requiring 
    manufacturers who offer this guarantee to add a ``Guaranteed 
    Thickness'' column to the required coverage charts.\122\ Rock Wool Mfg. 
    supported ICAA's proposal as one method of assuring that consumers 
    receive the total R-value claimed for (dry-applied) loose-fill 
    insulations in attics and other open areas.\123\ ICAA also proposed 
    adding the following language to section 460.8 to spell out the 
    obligations of manufacturers and installers regarding how the Rule's 
    tolerance provision applies where manufacturers guarantee that the 
    claimed R-value will be obtained when the installer applies at least 
    the ``guaranteed thickness'':

        \123\ Rock Wool Mfg./2, #39, at 1-3. Seel also Rock Wool 
    Manufacturing's comments concerning bag tabs, below.
    ---------------------------------------------------------------------------
    
        If you are a manufacturer of loose-fill insulation and you 
    guarantee R-value based upon thickness, your ``guaranteed 
    thickness'' must be an installed thickness that will result in at 
    least the minimum weight per square foot indicated on your label.
        If you are an installer, you must install at least the minimum 
    thickness and the minimum weight per square foot as indicated on the 
    manufacturer's label. If you install a ``Guaranteed Inches equal R-
    value'' loose-fill insulation product, you must install at least the 
    minimum thickness for the corresponding R-value as indicated of the 
    manufacturer's label.
    
    Disussion Regarding Disclosure of ``Minimum Thickness''
    
        ICAA has long taken the position that installers have difficulty 
    using bag count (or weight of insulation material installed) as the 
    measure of their compliance with the Rule (and of whether they have 
    installed the required amount of insulation material). ICAA contends 
    that the reason for this problem is that the person applying loose-fill 
    insulation through a blowing hose in the attic has no way of knowing at 
    any given point how many bags have been loaded into the hopper of the 
    blowing machine located in the truck outside. Requiring manufacturers 
    to add a disclosure of ``initial installed thickness'' to coverage 
    charts would give installers an additional tool to help them when they 
    are applying dry-applied loose-fill insulation products. This 
    additional information would not, however, allow installers to comply 
    with the Rule simply by installing the claimed initial installed 
    thickness, without having to count the number of bags they have 
    installed (or otherwise ensure they have applied the required amount of 
    insulation material) that is necessary, along with thickness, to 
    achieve the claimed total R-value. Because dry-applied loose-fill 
    insulation products normally settle after installation, the Rule 
    requires: (1) That each manufacturer determine the R-value of its home 
    insulation product at settled density and construct coverage charts 
    showing the minimum settled thickness, minimum weight per square foot, 
    and coverage area per bag for various total R-values; and (2) that 
    installers measure the area to be covered and install the number of 
    bags (and weight of insulation material) indicated on the insulation 
    product's coverage chart for the total R-value desired. These 
    requirements are necessary because the claimed total R-value for a 
    specific dry-applied loose-fill insulation can be attained only when 
    the requisite amount of insulation material in both thickness and 
    density has been installed.
        Further, it does not appear that recognized procedures are 
    currently available that could be used to determine, on a uniform 
    basis, a required initial thickness for all types of dry-applied loose-
    fill insulations. The settled density test procedure in ASTM C 739-91, 
    which is required for determining the R-value test specimen density for 
    dry-applied cellulose insulation, includes an initial blown step that 
    could serve as the basis for determining an initial installed thickness 
    for cellulose; but ASTM has not adopted a similar test procedure for 
    dry-applied loose-fill mineral fiber insulations. Without reliable 
    procedures to determine initial installed thickness, claims on coverage 
    charts of competing insulations might not be consistent, and could be 
    misleading. Further, because the initial thickness applied may vary 
    with the blowing equipment and application technique used, even for 
    cellulose (where a standardized test procedure is available to use in 
    determining an initial installed thickness), an installer who applied 
    the initial thickness determined under the required settled density 
    test procedure would still have to ensure that he had applied the 
    necessary amount of insulation material.
        Requiring (or allowing) manufacturers who claim a ``guaranteed 
    thickness'' for their dry-applied loose-fill insulations to include a 
    ``guaranteed thickness'' column in their coverage charts on labels and 
    fact sheets required by the Rule, as suggested by ICAA and Rock Wool 
    Mfg., raises similar, but even more complicated, issues. Adding this 
    disclosure might provide useful information. Without a uniform, 
    verifiable means of determining an initial thickness that will achieve 
    the claimed total R-value in all applications,\124\ however, the 
    Commission does not believe it would be appropriate to require, or 
    allow, manufacturers to add this information to the required 
    manufacturers' coverage charts, or to allow installers to rely on the 
    ``guaranteed thickness'' alone (and not also on bag count) in 
    determining the amount of insulation to apply to achieve the claimed 
    total R-value.
    ---------------------------------------------------------------------------
    
        \124\ From a practical standpoint, providing a ``guaranteed 
    thickness'' may make many insulation products less competitive. 
    Because of variabilities in blowing equipment and application 
    techniques among installers, manufacturers making such a guarantee 
    may have to claim on their coverage chart that a considerably 
    greater thickness (and more insulation material) than normal is 
    necessary to guarantee that if the installer applies the 
    ``guaranteed thickness,'' the claimed total R-value will be achieved 
    under all possible circumstances.
    ---------------------------------------------------------------------------
    
        For these reasons, the Commission does not propose amending the 
    Rule to require the disclosure of an ``initial installed thickness'' or 
    of a manufacturer's voluntary ``guaranteed thickness'' at this time. 
    The Commission, however, solicits comments regarding how manufacturers 
    of all types of dry-applied loose-fill insulations and stabilized 
    insulations could determine an initial installed thickness, or a 
    guaranteed thickness, for each total R-value claimed, whether the 
    Commission should require the addition of this information to the 
    required coverage chart for either dry-applied loose-fill insulations 
    or stabilized insulations, and under what circumstances installing the 
    ``initial installed thickness'' or ``guaranteed thickness'' of 
    insulation could be a sufficient basis alone for installers to ensure 
    that they have applied the requisite amount of insulation material.
    
    Comments Regarding the Use of Tabs or Seals on Packages
    
        NAIMA recommended requiring manufacturers to attach to or print on 
    each bag of loose-fill insulation a single, unique tab or seal 
    identifying the product, and that installers clip the tabs from each 
    bag used and attach them to the customer's receipt. \125\ Tascon 
    asserted that requiring installers to give the consumer the tabs or 
    labels from
    
    [[Page 48045]]
    
    each bag installed would be an effective way to prevent cheating. \126\ 
    Rock Wool Mfg. and ICAA opposed requiring the use of bag tabs. \127\

    (any method of R-value verification dependent on an installer 
    correctly measuring the dimensions of a house and calculating the 
    attic's square footage to be insulated with loose-fill insulation is 
    inherently flawed because even the best installers make errors in 
    measuring and arithmetic, suggested alternatives it considered 
    superior for assuring the accuracy of R-value representations).
    ---------------------------------------------------------------------------
    
    Discussion Regarding the Use of Tabs or Seals on Packages
    
        The Commission does not believe that sufficient evidence has been 
    presented that requiring the use of bag tabs would add materially to 
    the Rule's existing requirements that installers install the 
    appropriate amount the insulation and disclose, in receipt to 
    customers, the number of bags of loose-fill insulation installed. The 
    Commission, therefore, does not propose amending the Rule to require 
    the use of tabs.
    
    Comments Regarding Advising Consumers How To Verify R-value Installed
    
        ICAA recommended that the Commission amend the Rule to include a 
    statement in fact sheets for loose-fill insulations advising consumers 
    that ICAA can provide them with information about how they can verify 
    the total R-value of loose-fill insulations installed in attics of new 
    homes or added to existing attics. \128\

        \128\ ICAA/1, #17, at 9.
    ---------------------------------------------------------------------------
    
    Discussion Regarding Advising Consumers How To Verify R-value Installed
    
        To the extent that the CABO/MEC already includes requirements and 
    procedures for building inspectors to determine whether the required 
    amount of insulation has been installed in new construction, it may not 
    be necessary or appropriate for the Commission to require additional 
    disclosures in manufacturers' fact sheets or elsewhere. For this 
    reason, the Commission does not propose amending the Rule to require 
    this additional disclosure, although this information may be provided 
    voluntarily in other promotional materials. The Commission solicits 
    comments, however, regarding whether (and in what manner) the proposed 
    disclosure would provide benefits beyond the CABO/MEC requirements and 
    procedures relating to building inspections, and whether (and to what 
    extent) there currently are abuses in the sale and installation of home 
    insulation that could be remedied by requiring this additional 
    disclosure, and the costs of manufacturers that would be imposed by a 
    requirement that they include this disclosure on labels or in fact 
    sheets.
    
    d. Disclosures for Urea-based Foam Insulations
    
    Comments
    
        In the original rulemaking proceeding, the Commission determined 
    that the inherent qualities of urea-formaldehyde (``UF'') foam 
    insulations, which were being installed at that time in wall cavities 
    only by professional installers, would cause the products to lose 
    volume, or ``shrink.'' This shrinkage caused the insulation to pull 
    away from the wall cavity in all three directions after installation, 
    leaving the wall partially uninsulated and resulting in a lower than 
    claimed R-value. Although both the rate and extent of shrinkage 
    depended somewhat on the the quality of the chemicals and the product's 
    on-site formulation and application, even if a UF insulation product 
    was installed perfectly, it would shrink and its R-value would 
    decrease. To address this problem, the Rule requires that 
    manufacturers' disclosure the product's R-value in a manner that 
    accounts for the product's shrinkage, or include a specific disclosure 
    about the effect of shrinkage on R-value. 44 FR at 50220, 50231.
        Celotex and PIMA recommended that the Commission revise the 
    statement to refer to ``urea-based form insulation,'' because the 
    reference to ``foam insulation'' implies that all foam-type insulation 
    products (including other types of cellular plastics insulations) 
    shrink after installation, resulting in lower R-values than claimed. 
    \129\ PIMA stated that UF insulation is no longer sold, and that this 
    disclosure is unnecessary and may cause consumer confusion about other 
    foam-type insulations. \130\

    ---------------------------------------------------------------------------
    
    Discussion
    
        The Commission intended to limit this disclosure to UF insulations. 
    Because it appears that UF foam insulation no longer is being sold, 
    however, instead of clarifying this reference, the Commission proposes 
    amending the Rule to delete this obsolete requirement. The Commission 
    solicits commends on this proposal, especially regarding whether any UF 
    insulation products are still being sold, and whether there are other 
    insulation products currently on the market that may be subject to 
    shrinkage that affects R-value.
    2. Disclosures in Advertising and Other Promotional Materials
    
    1. Disclosures Required
    
    Background
    
        Sections 460.18 and 460.19 of the Rule specify disclosure 
    requirements for advertisements and other promotional materials 
    (including those on the Internet) for home insulation products aimed at 
    consumers that are distributed by manufactures, professional 
    installers, or retailers. They require disclosures only if the 
    advertisement or other promotional material includes certain claims 
    about a specific insulation product. The disclosure requirements do not 
    apply to advertisements on television. In general, any advertisement or 
    other promotional material that includes an R-value, thickness, or 
    price must disclose the type of insulation, the product's R-value and 
    the thickness needed to get that R-value, and the following R-value 
    explanatory statement: ``The higher the R-value, the greater the 
    insulating power. Ask your seller for the fact sheet on R-values.\131\
    ---------------------------------------------------------------------------
    
        \131\ All labels and fact sheets must include a version of the 
    R-value explanatory statement, specifically: ``R means resistance to 
    heat flow. The higher the R-value, the greater the insulating 
    power.''
    ---------------------------------------------------------------------------
    
        Advertisements and other promotional materials that state a price 
    also must include the coverage area at the stated thickness. Those that 
    state the price per square foot need not disclose the coverage area. If 
    the advertisement or other promotional material compares one type of 
    insulation to another, the comparison must be based on the same 
    coverage area and the R-value of each at a specific thickness must be 
    disclosed. It it includes the price of each insulation, it must include 
    the coverage area for the price and thickness claimed. If it claims 
    only price per square foot, it need not disclose coverage area.
        Advertisements, labels, and other promotional materials that 
    contain an energy savings claim for an insulation product (e.g., ``save 
    25% on heating bills'') must include the following energy savings 
    explanatory statement: ``Savings vary. Find out why in the seller's 
    fact sheet on R-values. Higher R-values mean greater insulating 
    power.'' When both the energy savings explanatory statement and the R-
    value explanatory statement are triggered by the claims, the seller 
    need only include the energy savings explanatory statement.
        Advertisements, labels and other promotional materials that contain 
    a
    
    [[Page 48046]]
    
    claim that a combination of products including insulation can cut fuel 
    bills or fuel use must also list the products used and state how much 
    of the savings comes from each product, in addition to giving the 
    energy savings explanatory statement. If the advertiser cannot give 
    exact or approximate figures, it must give a ranking of the products.
    
    Discussion
    
        No comment addressed the required disclosures for advertisements 
    and other promotional materials or suggested amending the rule to 
    eliminate any of them. The Commission, however, wants to ensure that 
    the rule does not impose unnecessary burdens on advertising and other 
    promotional materials. When the Commission promulgated the Rule, it 
    considered but rejected a proposal that it limit the required 
    disclosure of the R-value explanatory statement to a specific period of 
    time following the rule's effective date. Because insulation is a very 
    infrequently purchased commodity, the Commission was uncertain that the 
    R-value concept would become widely and permanently understood in a 
    short period of time. The Commission stated it would reexamine in the 
    future the need to continue requiring the R-value explanatory statement 
    in advertisements. 44 FR at 50233. The Commission, therefore, solicits 
    comments on whether it should propose amending the rule to eliminate 
    the requirement that advertisements and other promotional materials 
    that include the triggering claims specified in the Rule include the R-
    value explanatory statement, or the portion of the savings explanatory 
    statement that explains the meaning of R-value.
        In raising this issue for comment, the Commission is not 
    considering eliminating the other disclosures for advertisements and 
    other promotional materials that include an R-value, thickness, price, 
    comparison claim, or energy savings claim. Those required disclosures 
    are necessary to prevent the triggering claims from being unfair or 
    deceptive. Further, the Commission is not considering eliminating the 
    required disclosure of the meaning of R-value from labels or 
    manufacturers' fact sheets. The disclosure on labels and fact sheets is 
    necessary to ensure that consumers have the information they need to 
    understand the R-value information contained on labels, fact sheets, 
    and in advertising and other promotional materials; but the definition 
    on labels and fact sheets that are available to consumers at the point 
    of purchase may make the additional disclosure in advertisements and 
    other promotional materials unnecessary.
        Comments should address specifically the current need for the 
    definition of R-value in advertisements and other promotional 
    materials, the current state of consumers' understanding of the term R-
    value, and whether the availability of the meaning of R-value on labels 
    and manufacturers' fact sheets is sufficient to provide this necessary 
    information to consumers prior to purchase. Commenters are requested to 
    include data such as consumer perception studies that are relevant to 
    these questions.
    
    b. Advertising on Radio
    
    Comments
    
        NAIMA recommended that the Commission exclude radio ads from the 
    Rule's disclosure requirements for advertisements. NAIMA contended that 
    radio advertisements are similar to television advertisements, which 
    the Rule excludes from any disclosure requirements.\132\

    Discussion
    
        The Rule originally applied the advertising disclosure 
    requirements, which require disclosures only in advertisements that 
    contain specific triggering claims, to television advertisements as 
    well as all other types of advertising and promotional materials. 
    Unlike other types of advertising, which simply must include the 
    required disclosures ``clearly and conspicuously,'' the Rule as 
    originally promulgated included very specific requirements regarding 
    the manner in which required disclosures would have to be made in 
    television advertising.\133\ Four insulation manufacturers appealed the 
    disclosure requirements for television advertising, asserting that the 
    requirements, particularly in light of the manner in which the 
    disclosures would have to be made, were particularly burdensome for 
    short television ads. The Commission settled the appeal by agreeing not 
    to impose disclosure requirements on television ads without conducting 
    further rulemaking proceedings, and rescinded the requirements without 
    conducting further proceedings.\134\ No evidence was presented in the 
    original rulemaking or in the appeal concerning any similar burdens 
    that the disclosure requirements would impose on radio ads. 
    Accordingly, the Commission does not propose revising the Rule to 
    exempt radio ads from making these important disclosures, but will 
    accept comments on how the costs of making the required disclosures in 
    radio ads compare to the benefits the disclosures provide to consumers.
    ---------------------------------------------------------------------------
    
        \133\ 44 FR at 5045 Appendix B (1979). For example, TV ads 
    containing triggering claims would have been required to make the 
    disclosures simultaneously in both the audio and video portions of 
    the ad, the video portion of the disclosure would have to have 
    appeared in letters of sufficient size to be easily seen and read on 
    television sets of all sizes, and the disclosures would have been 
    required each time a triggering claim was made. The Rule also would 
    have restricted the video background and other sounds during the 
    audio disclosures. The Rule contains no similar restrictions 
    concerning the manner in which disclosures must be made in radio 
    advertising, as long as they are made clearly and conspicuously.

    3. Disclosures by Installers or New Home Sellers
    
    a. Fact Sheets
    
    Comments
    
        Celotex and PIMA recommended that the Commission require that 
    professional installers (under section 460.15) give a copy of the 
    manufacturer's fact sheet to consumers upon completion of the 
    installation, and that new home sellers (under section 460.16) give a 
    copy of the fact sheet to new home buyers.\135\ Celotex and PIMA 
    asserted that these requirements would ensure the dissemination of fact 
    sheets to consumers and promote the purpose of the Rule--that consumers 
    receive accurate and meaningful information.
    ---------------------------------------------------------------------------
    
        \135\ Celotex, #25, at 2; PIMA, #30, at 3.
    ---------------------------------------------------------------------------
    
    Discussion
    
        The Commission required fact sheets to provide pre-purchase 
    information to consumers who otherwise probably would not see the 
    information on package labels. Moreover, to minimize the burdens that 
    the Rule imposes on industry members, the Commission required only that 
    installers show the fact sheets to consumers prior to purchase and give 
    them specific disclosures in contracts or receipts about the insulation 
    installed. Similarly, it required new home sellers to disclose in the 
    sales contract, prior to purchase, specific information about the 
    insulation installed (or to be installed) in the new home. The 
    Commission has received no evidence that would justify requiring that 
    installers or new home sellers provide fact sheets, after the purchase, 
    that disclosure R-value information other than for the insulation the 
    consumer has purchased. Accordingly, the Commission does not propose 
    amending the Rule to require that the additional information suggested 
    by the comments be provided.
    
    [[Page 48047]]
    
    b. Attic Cards and Certificates
    
    Comments
    
        ICAA proposed that the Commission require new home sellers to make 
    disclosures to purchasers in attic cards signed by the new home seller, 
    builder, and/or building inspector. These attic cards would be used 
    only to make disclosures concerning the insulation installed in the 
    attic of the new home, would include the information required on the 
    package label of the insulation, and would be posted adjacent to the 
    attic access or scuttle. ICAA contended that attic cards would provide 
    consumers with pertinent information at no significant cost to industry 
    members, would reduce confusion for building inspectors and homeowners, 
    and would be a constructive tool to help ensure that installers meet 
    specifications. ICAA stated that attic cards have been required by the 
    State of Florida since 1991, by the Bonneville Power Administration, by 
    Georgia Power Company's energy efficiency program, and by several other 
    jurisdictions throughout the country. ICAA also stated that the 1995 
    CABO/MEC recommends that the installer provide a signed, dated, and 
    posted certification for insulation installed in each element of the 
    building envelope, listing the type of insulation, the manufacturer, 
    and the R-value.\136\ NAIMA similarly recommended that the Commission 
    amend the Rule to add language, similar to that in the 1995 CABO/MEC, 
    to require professional installers to provide certification of the 
    insulation installed and to post the certification in a conspicuous 
    place on the job site.\137\

    ---------------------------------------------------------------------------
    
    Discussion
    
        Although the Commission's staff in the original rulemaking 
    recommended that the Commission require the use of attic cards to make 
    disclosures to consumers,\138\ the Commission determined that such a 
    requirement was not necessary in light of the Rule's requirement that 
    new home sellers and installers give consumers written disclosures in 
    contracts or written receipts. Attic cards are usually posted in the 
    attic near the access opening, for later reference by building code 
    inspectors and future owners of the home (as well as the original 
    purchaser), or by the homeowner who has insulation added to an existing 
    home. The Rule, on the other hand, already requires installers and new 
    home sellers to provide consumers with the same information in 
    contracts that would be disclosed on an attic card or in a 
    certification. If the seller or consumer prefers, the contract or 
    receipt can be posted in the form on an attic card after the seller has 
    given the written disclosures to the consumer.
    ---------------------------------------------------------------------------
    
        \138\ Staff Report at 237-38.
    ---------------------------------------------------------------------------
    
        Further, for insulations installed in attics of new residential 
    construction, the CABO/MEC requires that installers provide a signed 
    and dated certification for the insulation installed in each part of 
    the home, listing the type of insulation, the insulation manufacturer, 
    and the total R-value, and post the certification in a conspicuous 
    place on the job site.\139\ These requirements have been adopted for 
    use in federal government programs covering new residential 
    construction and by 33 states, at some level.\140\
    ---------------------------------------------------------------------------
    
        \139\ For blown or sprayed insulation, the installer must also 
    provide the initial installed thickness, the settled thickness, the 
    coverage area, and the number of bags installed.
        \140\ See Part III.E.1.b, supra.
    ---------------------------------------------------------------------------
    
        For these reasons, the Commission does not propose amending the 
    Rule to require additional certification or the use of attic cards. The 
    Commission solicits comments, however, regarding whether (and in what 
    manner, and to what extent) amending the Rule to require that 
    disclosures be made in certifications or attic cards would provide 
    benefits beyond those currently required by the Rule or the CABO/MEC 
    for consumers or building inspectors, and whether (and to what extent) 
    there currently are abuses in the sale and installation of home 
    insulation that could be remedied by including these additional 
    disclosure requirements in the Rule, and the costs to installers and 
    new home sellers of providing the disclosures in certifications and 
    attic cards.
    
    c. Attic Rulers
    
    Comments
    
        ICAA recommended that the Commission require that new home sellers 
    and professional installers apply attic rulers (or thickness markers) 
    for every 500 square feet of attic space, with a minimum of three 
    rulers, when loose-fill insulation is installed in the attics of new or 
    existing homes. ICAA asserted that, like attic cards, attic rulers have 
    been required by the State of Florida since 1991, and are required 
    under the Georgia Power Company's program to encourage energy efficient 
    homes. ICAA contended that the rulers would assist inspectors and 
    consumers in evaluating settled thickness levels and determining 
    whether consumers received the R-value of loose-fill insulation 
    claimed. According to ICAA, the 1995 CABO/MEC proposes the use of attic 
    rulers, installed at least one for every 300 square feet in the attic, 
    and requires that they be affixed to the attic trusses or joists, be 
    marked with minimum initial thickness and minimum settled thickness, 
    and face the attic access.\141\ NAIMA similarly recommended that the 
    Commission amend the Rule to require that blown-in loose-fill and 
    spray-applied attic insulations be installed in a manner that would 
    permit verification that the necessary thickness of insulation was 
    installed; specifically, by requiring that thickness markers or attic 
    rulers labeled in inches be installed at least one for every 300 square 
    feet. NAIMA stated that this requirement is similar to requirements in 
    the 1995 CABO/MEC and to requirements of some states.\142\

    ---------------------------------------------------------------------------
    
    Discussion
    
        It is essential that both the required density (and weight per 
    square foot) and thickness of loose-fill insulations and stabilized 
    insulations be installed to attain a specific total R-value. The use of 
    attic rulers could help installers apply a sufficient thickness to 
    achieve a specific total R-value, and to apply it in a level and 
    consistent manner (although they still would have to ensure that they 
    apply the required number of bags and weight of insulation material). 
    The use of attic rulers could be particularly beneficial if 
    manufacturers included a verified initial installed thickness 
    disclosure or a guaranteed thickness disclosure on the bag label 
    coverage chart.\143\ Attic rulers also could give consumers a ready 
    means of determining, both initially and over time, whether the 
    required minimum thickness has been installed.
    ---------------------------------------------------------------------------
    
        \143\ See Part III.E.1.c, supra.
    ---------------------------------------------------------------------------
    
        The CABO/MEC already requires, for new residential construction, 
    that installers apply blown loose-fill or sprayed (e.g., stabilized) 
    insulation in atticks with the use of thickness markers labeled in 
    inches, attached to the trusses or joists at least one for every 300 
    square feet (28 m\2\), marked with the minimum initial installed 
    thickness and minimum settled thickness, and installed facing the attic 
    access. Because the CABO/MEC requires the use of attic rulers in new 
    construction, the Commission does not propose amending the Rule to 
    require their use. The Commission solicts comments, however, regarding 
    whether (and in what manner, and to what
    
    [[Page 48048]]
    
    extent) amending the Rule to require the use of thickness markers would 
    provide benefits beyond those currently required by the CABO/MEC for 
    consumers or building inspectors, whether (and to what extent) there 
    currently are abuses in the sale and installation of home insulation 
    that could be remedied by amending the Rule to require the use of 
    thickness markers, and the costs to installers and new home sellers of 
    installing and using thickness markers.
    4. Disclosures by Retailers
    
    Background
    
        Section 460.14 of the Rule requires retailers who sell insulation 
    to do-it-yourself consumers to make the manufacturers' fact sheets for 
    the home insulation they sell available to consumers prior to purchase. 
    The retailer can decide how to do so, as long as consumers are likely 
    to notice the fact sheets. For example, the retailer can put them in 
    displays and let consumers take copies, or can keep them in a binder 
    and have a sign telling consumers where the fact sheets are. The 
    purpose of this requirement is to ensure that consumers have the 
    information they need about home insulation prior to purchase to enable 
    them to make cost-based purchasing decisions. When the Commission 
    promulgated the Rule, bulky insulation packages were not normally 
    available on the retailer's sales floor, so the consumer would not see 
    the disclosures on labels prior to purchase. In addition, the fact 
    sheets contain additional information about energy savings and other 
    factors the consumer should consider when purchasing home insulation. 
    See Part IV.E.1.a, above.
    
    Discussion
    
        No comment addressed the requirement that retailers make the 
    manufacturers' fact sheets available to consumers. In the years since 
    the Commission promulgated the Rule, however, the nature of retail 
    sales of home insulation to do-it-yourself consumers has changed. 
    Today, retailers often sell home insulation directly from warehouse-
    type sales floors where consumers select the packages of insulation 
    they want. Therefore, the R-value and related information on the 
    packages is available to consumers prior to purchase. In response to 
    questions from retailers, the Commission's staff has advised that 
    retailers need not make separate fact sheets available at the point of 
    purchase if all the required fact sheet disclosures are made on the 
    insulation package and if the insulation packages are available on the 
    sales floor for the consumer to inspect prior to purchase. The 
    Commission affirms the staff's advice, proposes amending the Rule to 
    codify this option, and solicits comments on the proposal.
    
    V. Questions for Comment
    
        Members of the public are invited to comment on any issues or 
    concerns they believe are relevant or appropriate to the Commission's 
    consideration of the proposed amendments to the R-value Rule, or about 
    other issues and questions the Commission raises in the discussion in 
    Part IV, above. The Commission requests that factual data, including 
    consumer perception or survey data, upon which the comments are based 
    be submitted with the comments.
        To assist commenters, the Commission provides the following list of 
    proposed amendments. The proposed amendments would: (1) Clarify 
    specific provisions of the Rule (Parts IV.D.3 and IV.E.1.b); (2) 
    require disclosure of the same R-value information for competing types 
    of loose-fill insulation products (Part IV.E.1.c); (3) specify the use 
    of current ASTM or other recognized procedures for preparing R-value 
    test specimens of spray-applied insulations (Part IV.C.2.b) and for 
    conducting R-value tests of multi-sheet reflective insulation products 
    (Part IV.D.5.a.ii); (4) delete specific disclosure requirements for 
    urea formaldehyde insulation, which no longer is sold (Part IV.E.1.d); 
    and (5) excuse retailers from making available to consumers separate 
    manufacturers' fact sheets under certain circumstances (Part IV.E.4).
        The Commission also requests comments on whether the Commission 
    should propose amendments to: (1) Cover additional products (i.e., 
    residential pipe and duct insulations, and insulation sold for use in 
    commercial buildings) (Part IV.A); (2) require the disclosure of in-use 
    performance values, as opposed to laboratory tests under static, 
    uniform conditions, or of the performance of building systems (Part 
    IV.B); (3) adopt additional test specimen preparation requirements to 
    account for various factors that affect R-values (Part IV.C); (4) adopt 
    additional or updated testing requirements (Part IV.D); and (5) revise 
    the disclosure requirements for manufacturers' labels and fact sheets, 
    advertisements and other promotional materials, and for professional 
    installers, new home sellers, and retailers (Part IV.E).
        In addition to the specific questions regarding each of these 
    issues raised in the cited portions of this notice, the Commission 
    solicits comments on the questions below. The questions are designed to 
    assist the public and should not be construed as a limitation on the 
    issues on which public comments may be submitted.
        To maximize the benefits and minimize the costs for consumers and 
    sellers (including specifically small businesses), for each amendment 
    proposed by the Commission, and by comments filed in response to this 
    notice, the Commission in general solicits views and data on the 
    following questions:
        (1) What benefits would the proposed requirements confer, and on 
    whom?
        (2) What paperwork burdens would the proposed requirements impose, 
    and on whom?
        (3) What other costs or burdens would the proposed requirements 
    impose, and on whom?
        (4) What regulatory alternatives to the proposed requirements are 
    available that would reduce the burdens of the proposed requirements, 
    while providing the same benefits?
        (5) What impact, either positive or negative, would the proposed 
    requirements likely have on the environment?
