This part deals with R-value claims, as well as home insulation labels, fact sheets, ads, and other promotional materials in or affecting commerce, as “commerce” is defined in the Federal Trade Commission Act. If you are covered by this part, breaking any of its rules is an unfair or deceptive act or practice or an unfair method of competition under Section 5 of that Act. You can be fined heavily (up to the civil monetary penalty amount specified in § 1.98 of this chapter) each time you break a rule.

Insulation is any material mainly used to slow heat flow. It may be mineral or organic, fibrous, cellular, or reflective. It may be in rigid, semirigid, flexible, or loose-fill form. Home insulation is for use in old or new homes, condominiums, cooperatives, apartments, modular homes, or mobile homes. It does not include pipe insulation. It does not include any kind of duct insulation except for duct wrap. It also includes insulation developed and marketed for commercial or industrial buildings that is also marketed for and used in residential buildings.

You are covered by this part if you are a member of the home insulation industry. This includes individuals, firms, partnerships, and corporations. It includes manufacturers, distributors, franchisors, installers, retailers, utility companies, and trade associations. Advertisers and advertising agencies are also covered. So are labs doing tests for industry members. If you sell new homes to consumers, you are covered. If you make R-value claims for non-insulation products described in § 460.22, you are covered by the requirements of that section.

You must follow the rules in this part each time you import, manufacture, distribute, sell, install, promote, or label home insulation. You must follow them each time you prepare, approve, place, or pay for home insulation labels, fact sheets, ads, or other promotional materials for consumer use. You must also follow them each time you supply anyone covered by this part with written information that is to be used in labels, fact sheets, ads, or other promotional materials for consumer use. Testing labs must follow the rules unless the industry members tell them, in writing, that labels, fact sheets, ads, or other promotional materials for home insulation will not be based on the test results. You must follow the requirements in § 460.22 each time you make an R-value claim for non-insulation products marketed in whole or in part to reduce residential energy use by slowing heat flow.

R-value measures resistance to heat flow. R-values given in labels, fact sheets, ads, or other promotional materials must be based on tests done under the methods listed in paragraphs (a) through (d) of this section.

(a) All types of insulation except reflective insulation must be tested with ASTM C177-13, “Standard Test Method for Steady-State Heat Flux Measurements and Thermal Transmission Properties by Means of the Guarded-Hot-Plate Apparatus;” ASTM C518-17, “Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus;” ASTM C1363-11, “Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus” or ASTM C1114-06, “Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Thin-Heater Apparatus.” The tests must be done at a mean temperature of 75 degrees Fahrenheit and with a temperature difference of 50 degrees Fahrenheit plus or minus 10 degrees Fahrenheit. The tests must be done on the insulation material alone (excluding any airspace). R-values (“thermal resistance”) based upon heat flux measurements according to ASTM C177-13 or ASTM C518-17 must be reported only in accordance with the requirements and restrictions of ASTM C1045-07, “Standard Practice for Calculating Thermal Transmission Properties Under Steady-State Conditions.”

(1) For polyurethane, polyisocyanurate, and extruded polystyrene, the tests must be done on samples that fully reflect the effect of aging on the product's R-value.

(2) For loose-fill cellulose, the tests must be done at the settled density determined under paragraph 8 of ASTM C739-17, “Standard Specification for Cellulosic Fiber Loose-Fill Thermal Insulation.”

(3) For loose-fill mineral wool, self-supported, spray-applied cellulose, and stabilized cellulose, the tests must be done on samples that fully reflect the effect of settling on the product's R-value.

(4) For self-supported spray-applied cellulose, the tests must be done at the density determined pursuant to ASTM C1149-17, “Standard Specification for Self-Supported Spray Applied Cellulosic Thermal Insulation.”

(5) For loose-fill insulations, the initial installed thickness for the product must be determined pursuant to ASTM C1374-14, “Standard Test Method for Determination of Installed Thickness of Pneumatically Applied Loose-Fill Building Insulation,” for R-values of 13, 19, 22, 30, 38, 49 and any other R-values provided on the product's label pursuant to § 460.12.

(b) Single sheet reflective insulation materials must be tested with ASTM E408-13, “Standard Test Methods for Total Normal Emittance of Surfaces Using Inspection-Meter Techniques,” or ASTM C1371-15, “Standard Test Method for Determination of Emittance of Materials Near Room Temperature Using Portable Emissometers.” This test determines the emittance of the reflective surfaces—its power to radiate heat. To get the R-value for a specific emittance, air space, and direction of heat flow, use Table 3 in the ASHRAE Handbook, Chapter 26, if the product is intended for applications that meet the conditions specified in the tables. You must use the R-value shown for 50 degrees Fahrenheit, with a temperature difference of 30 degrees Fahrenheit.

(c) Reflective insulation systems with more than one sheet, and single sheet systems that are intended for applications that do not meet the conditions specified in Table 3 in the ASHRAE Handbook, Chapter 26 must be tested with ASTM C1363-11, “Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus,” in a test panel constructed according to ASTM C1224-15, “Standard Specification for Reflective Insulation for Building Applications,” and under the test conditions specified in ASTM C1224-15. To get the R-value from the results of those tests, use the formula specified in ASTM C1224-15.

(d) For insulation materials with reflective facings, you must test the R-value of the material alone (excluding any air spaces) under the methods listed in paragraph (a) of this section. You can also determine the R-value of the material in conjunction with an air space. You can use one of two methods to do this:

(1) You can test the system, with its air space, under ASTM C1363-11, “Standard Test Method for Thermal Performance of Building Materials and Envelope Assemblies by Means of a Hot Box Apparatus” If you do this, you must follow the requirements in paragraph (a) of this section on temperature, aging and settled density.

(2) You can add up the tested R-value of the material and the R-value of the air space. To get the R-value for the air space, you must follow the requirements in paragraph (b) of this section.

(e) The standards required in this section are incorporated by reference into this section with the approval of the Director of the Federal Register under 5 U.S.C. 552(a) and 1 CFR part 51. All approved material is available for inspection at the FTC Library (202-326-2395), Federal Trade Commission, Room H-630, 600 Pennsylvania Avenue NW, Washington, DC 20580 and is available from the sources listed in paragraphs (e)(1) and (2) of this section.

All tests except reflective insulation tests must be done at a representative thickness for every thickness shown in a label, fact sheet, ad, or other promotional material. “Representative thickness” means a thickness at which the R-value per unit will vary no more than plus or minus 2% with increases in thickness. However, if the thickness shown in your label, fact sheet, ad, or promotional material is less than the representative thickness, then you can test the insulation at the thickness shown.

If you are a manufacturer of home insulation, no individual specimen of the insulation you sell can have an R-value more than 10% below the R-value shown in a label, fact sheet, ad, or other promotional material for that insulation. If you are not a manufacturer, you can rely on the R-value data given to you by the manufacturer, unless you know or should know that the data is false or not based on the proper tests.

Manufacturers and testing labs must keep records of each item of information in the “Report” section of the ASTM test method that is used for a test. They must also keep the following records:

(a) The name and address of the testing lab that did each test.

(b) The date of each test.

(c) For manufacturers, the date each test report was received from a lab. For labs, the date each test report was sent to a manufacturer.

(d) For extruded polystyrene, polyurethane, and polyisocyanurate, the age (in days) of the specimen that was tested.

(e) For reflective insulation, the emittance level that was found in the test.

All statements called for by this regulation must be made clearly and conspicuously. Among other things, you must follow the Commission's enforcement policy statement for clear and conspicuous disclosures in foreign language advertising and sales materials, 16 CFR 14.9.

R-values shown in labels, fact sheets, ads, or other promotional materials must be rounded to the nearest tenth. However, R-values of 10 or more may be rounded to the nearest whole number.

If you are a manufacturer, you must label all packages of your insulation. The labels must contain:

(a) The type of insulation.

(b) A chart showing these items:

(1) For batts and blankets of any type: the R-value, length, width, thickness, and square feet of insulation in the package.

(2) For all loose-fill insulation: the minimum settled thickness, initial installed thickness, maximum net coverage area, number of bags per 1,000 square feet, and minimum weight per square foot at R-values of 13, 19, 22, 30, 38, and 49. You must also give this information for any additional R-values you list on the chart. Labels for these products must state the minimum net weight of the insulation in the package. You must also provide information about the blowing machine and machine settings used to derive the initial installed thickness information.

(3) For boardstock: the R-value, length, width, and thickness of the boards in the package, and the square feet of insulation in the package.

(4) For reflective insulation: The number of sheets; the number and thickness of the air spaces; and the R-value provided by that system when the direction of heat flow is up, down, and horizontal. You can show the R-value for only one direction of heat flow if you clearly and conspicuously state that the insulation can only be used in that application.

(5) For insulation materials with reflective facings, you must follow the rule in this section that applies to the material itself. For example, if you manufacture boardstock with a reflective facing, follow paragraph (b)(3) of this section. You can also show the R-value of the insulation when it is installed in conjunction with an air space. This is its “system R-value.” If you do this, you must clearly and conspicuously state the conditions under which the system R-value can be attained.

(6) For air duct insulation: the R-value, length, width, thickness, and square feet of insulation in the package.

(c) The following statement: “R means resistance to heat flow. The higher the R-value, the greater the insulating power.”

(d) If installation instructions are included on the label or with the package, add this statement: “To get the marked R-value, it is essential that this insulation be installed properly. If you do it yourself, follow the instructions carefully.”

(e) If no instructions are included, add this statement: “To get the marked R-value, it is essential that this insulation be installed properly. If you do it yourself, get instructions and follow them carefully. Instructions do not come with this package.”

If you are a manufacturer, you must give retailers and installers fact sheets for the insulation products you sell to them. Each sheet must contain what is listed here. You can add any disclosures that are required by federal laws, regulations, rules, or orders. You can add any disclosures that are required by State or local laws, rules, and orders, unless they are inconsistent with the provisions of this regulation. Do not add anything else. Each fact sheet must contain these items:

(a) The name and address of the manufacturer. It can also include a logo or other symbol that the manufacturer uses.

(b) A heading: “This is ________ insulation.” Fill in the blank with the type and form of your insulation.

(c) The heading must be followed by a chart:

(1) If § 460.12(b) requires a chart for your product's label, you must use that chart. For foamed-in-place insulations, you must show the R-value of your product at 3 1/2 inches. You can also show R-values at other thicknesses.

(2) You can put the charts for similar products on the same fact sheet. For example, if you sell insulation boards or batts in three different thicknesses, you can put the label charts for all three products on one fact sheet. If you sell loose-fill insulation in two different bag sizes, you can put both coverage charts on one fact sheet, as long as you state which coverage chart applies to each bag size.

(d) For air duct insulation, the chart must be followed by this statement:

(e) After the chart and any statement dealing with the specific type of insulation, ALL fact sheets must carry this statement, boxed, in 12-point type:

(f) For R-19 insulation batts, the fact sheet must also disclose the insulation's R-value when installed in wall cavities where the insulation's thickness exceeds the depth of the cavity.

If you sell insulation to do-it-yourself customers, you must have fact sheets for the insulation products you sell. You must make the fact sheets available to your customers, whether you offer insulation products for sale offline or online. You can decide how to do this, as long as your insulation customers are likely to notice them. For example, you can put them in a display, and let customers take copies of them. You can keep them in a binder at a counter or service desk, and have a sign telling customers where the fact sheets are. You need not make the fact sheets available to customers if you display insulation packages on the sales floor where your insulation customers are likely to notice them and each individual insulation package offered for sale contains all package label and fact sheet disclosures required by §§ 460.12 and 460.13. If you are offering products for sale online, the product labels and fact sheets required by this part, or a direct link to this information, must appear clearly and conspicuously and in close proximity to the covered product's price on each web page that contains a detailed description of the covered product and its price.

If you are an installer, you must have fact sheets for the insulation products you sell. Before customers agree to buy insulation from you, you must show them the fact sheet(s) for the type(s) of insulation they want. You can decide how to do this. For example, you can give each customer a copy of the fact sheet(s). You can keep the fact sheets in a binder, and show customers the binder before they agree to buy.

If you are a new home seller, you must put the following information in every sales contract: The type, thickness, and R-value of the insulation that will be installed in each part of the house. There is an exception to this rule. If the buyer signs a sales contract before you know what type of insulation will be put in the house, or if there is a change in the contract, you can give the buyer a receipt stating this information as soon as you find out.

If you are an installer, you must give your customers a contract or receipt for the insulation you install. For all insulation except loose-fill and reflective insulation, the receipt must show the coverage area, thickness, and R-value of the insulation you installed. The receipt must be dated and signed by the installer. To figure out the R-value of the insulation, use the data that the manufacturer gives you. If you put insulation in more than one part of the house, put the data for each part on the receipt. You can do this on one receipt, as long as you do not add up the coverage areas or R-values for different parts of the house. Do not multiply the R-value for one inch by the number of inches you installed. For loose-fill, the receipt must show the coverage area, initial installed thickness, minimum settled thickness, R-value, and the number of bags used. For reflective insulation, the receipt must show the number and thickness of the air spaces, the direction of heat flow, and the R-value.

(a) If your ad gives an R-value, you must give the type of insulation and the thickness needed to get that R-value. Also, add this statement explaining R-values: “The higher the R-value, the greater the insulating power. Ask your seller for the fact sheet on R-values.”

(b) If your ad gives a price, you must give the type of insulation, the R-value at a specific thickness, the statement explaining R-values in paragraph (a) of this section, and the coverage area for that thickness. If you give the price per square foot, you do not have to give the coverage area.

(c) If your ad gives the thickness of your insulation, you must give its R-value at that thickness and the statement explaining R-values in paragraph (a) of this section.

(d) If your ad compares one type of insulation to another, the comparison must be based on the same coverage areas. You must give the R-value at a specific thickness for each insulation, and the statement explaining R-values in paragraph (a) of this section. If you give the price of each insulation, you must also give the coverage area for the price and thickness shown. However, if you give the price per square foot, you do not have to give the coverage area.

(e) The affirmative disclosure requirements in this section do not apply to television or radio advertisements or to space-constrained advertisements. For the purposes of this part, “space-constrained advertisement” means any communication made through interactive media (such as the internet, online services, and software, including but not limited to internet search results and banner ads) that has space, format, size or technological limitations or restrictions that prevent industry members from making disclosures required by this part clearly and conspicuously. Industry members maintain the burden of showing that there is insufficient space to provide the disclosures that this part otherwise requires be made clearly and conspicuously.

(a) If you say or imply in your ads, labels, or other promotional materials that insulation can cut fuel bills or fuel use, you must have a reasonable basis for the claim. For example, if you say that insulation can “slash” or “lower” fuel bills, or that insulation “saves money,” you must have a reasonable basis for the claim. Also, if you say that insulation can “cut fuel use in half,” or “lower fuel bills by 30%,” you must have a reasonable basis for the claim.

(b) If you say or imply in your ads, labels, or other promotional materials that insulation can cut fuel bills or fuel use, you must make this statement about savings: “Savings vary. Find out why in the seller's fact sheet on R-values. Higher R-values mean greater insulating power.”

(c) If you say or imply that a combination of products can cut fuel bills or use, you must have a reasonable basis for the claim. You must make the statement about savings in paragraph (b) of this section. Also, you must list the combination of products used. They may be two or more types of insulation; one or more types of insulation and one or more other insulating products, like storm windows or siding; or insulation for two or more parts of the house, like the attic and walls. You must say how much of the savings came from each product or location. If you cannot give exact or approximate figures, you must give a ranking. For instance, if your ad says that insulation and storm doors combined to cut fuel use by 50%, you must say which one saved more.

(d) If your ad or other promotional material is covered by § 460.18 (a), (b), (c), or (d), and also makes a savings claim, you must follow the rules in §§ 460.18 and 460.19. However, you need not make the statement explaining R-value in § 460.18(a).

(e) Manufacturers are liable if they do not have a reasonable basis for their savings claims before the claim is made. If you are not a manufacturer, you are liable only if you know or should know that the manufacturer does not have a reasonable basis for the claim.

(f) Keep records of all data on savings claims for at least three years. For the records showing proof for claims, the three years will begin again each time you make the claim. Federal Trade Commission staff members can check these records at any time, but they must give you reasonable notice first.

(g) The affirmative disclosure requirements in this section do not apply to television or radio advertisements or to space-constrained advertisements. “Space-constrained advertisement” is defined in § 460.18(e).

In labels, fact sheets, ads, or other promotional materials, do not give the R-value for one inch or the “R-value per inch” of your product. There are two exceptions:

(a) If an outstanding FTC Cease and Desist Order applies to you but differs from the rules given here, you can petition to amend the order.

(b) You can do this if actual test results prove that the R-values per inch of your product does not drop as it gets thicker.

Do not say or imply that a government agency uses, certifies, recommends, or otherwise favors your product unless it is true. Do not say or imply that your insulation complies with a governmental standard or specification unless it is true.

If you make an R-value claim for a product, other than a fenestration-related product, that is not home insulation and is marketed in whole or in part to reduce residential energy use by slowing heat flow, you must test the product pursuant to § 460.5 using a test or tests in that section appropriate to the product. Any advertised R-value claims must fairly reflect the results of those tests. For the purposes of this section, fenestration-related products include windows, doors, and skylights as well as attachments for those products.

Do not say or imply that your product qualifies for a tax benefit unless it is true.

(a) If an outstanding FTC Cease and Desist Order applies to you but differs from the rules given here, you can petition to amend to order.

(b) State and local laws and regulations that are inconsistent with, or frustrate the purposes of, the provisions of this regulation are preempted. However, a State or local government may petition the Commission, for good cause, to permit the enforcement of any part of a State or local law or regulation that would be preempted by this section.

(c) The Commission's three-day cooling-off rule stays in force.

If any part of this regulation is stayed or held invalid, the rest of it will stay in force.

Section 18(g)(2) of the Federal Trade Commission Act, 15 U.S.C. 57a(g)(2), authorizes the Commission to exempt a person or class of persons from all or part of a trade regulation rule if the Commission finds that application of the rule is not necessary to prevent the unfair or deceptive acts or practices to which the rule relates. In response to petitions from industry representatives, the Commission has granted exemptions from specific requirements of this part to certain classes of sellers. Some of these exemptions are conditioned upon the performance of alternative actions. The exemptions are limited to specific sections of this part. All other requirements of this part apply to these sellers. The exemptions are summarized in paragraphs (a) through (d) of this appendix. For an explanation of the scope and application of the exemptions, see the formal Commission decisions cited in the authority citation to this part.

(a) Manufacturers of perlite insulation products that have an inverse relationship between R-value and density or weight per square foot are exempted from the requirements in §§ 460.12(b)(2) and 460.13(c)(1) that they disclose minimum weight per square foot for R-values listed on labels and fact sheets. This exemption is conditioned upon the alternative disclosure in labels and fact sheets of the maximum weight per square foot for each R-value required to be listed.

(b) Manufacturers of rigid, flat-roof insulation products used in flat, built-up roofs are exempted from the requirements in § 460.12 that they label these home insulation products.

(c)(1) New home sellers are exempted from:

(i) the requirement in § 460.18(a) that they disclose the type and thickness of the insulation when they make a representation in an advertisement or other promotional material about the R-value of the insulation in a new home;

(ii) the requirement that they disclose in an advertisement or other promotional material the R-value explanatory statement specified in § 460.18(a) or the savings explanatory statement specified in § 460.19(b), conditioned upon the new home sellers alternatively disclosing the appropriate explanatory statement in the sales contract along with the disclosures required by § 460.16;

(iii) the requirement that they make the disclosures specified in § 460.19(c) if they claim that insulation, along with other products in a new home, will cut fuel bills or fuel use; and

(iv) the requirement that they include the reference to fact sheets when they must disclose the R-value explanatory statement or the savings claim explanatory statement under § 460.18(a) or § 460.19(b), respectively.

(2) The exemptions for new home sellers also apply to home insulation sellers other than new home sellers when they participate with a new home seller to advertise and promote the sale of new homes, provided that the primary thrust of the advertisement or other promotional material is the promotion of new homes, and not the promotion of the insulation product.

(d) The requirements in §§ 460.6 through 460.21 do not apply to R-value claims covered by § 460.22.
