16 CFR 460.4: When the rules in this part apply.

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.
