# §460.20. R-value per inch claims.


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.
