Effective Dates: May 13, 2020

10. In §460.12, revise paragraphs (b)(4) and (5) to read as follows:

§460.12   Labels.

*   *   *   *   *

(b) *  *  *

(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.
