Roof

The thermal values for roof applications in post frame construction were derived by testing an assembly consisting of a corrugated metal exterior, 2" x 4" purlins, Radiant Reflect™ Insulation, a 2" x 6" to represent the top cord of a truss, and 1/2" wafer board. The thermal values are for both exposed insulation and applications where the insulation is covered for fire codes.

Thermal Values	Heat Flow Up	Heat Flow Down	U Value Up	U Value Down	K Value Up	K Value Down
Radiant Reflect™ w/Wafer Board	6.93	15.11	.144	.066	.144	.066
Radiant Reflect™ w/Metal Interior	6.22	14.40	.161	.069	.161	.069
Radiant Reflect™ Exposed to Interior	4.91*	12.81*	.204*	.078*	.204*	.078*

All Thermal Values are corrected for frame loss.
* Includes thermal resistance of 1.32 UP and 4.55 DOWN for interior air film.

Walls

The thermal values for Radiant Reflect™ installed in the walls of post frame buildings are based on testing of an assembly consisting of corrugated metal exterior, 2" x 4" girts, Radiant Reflect™ Insulation, a 4" x 6" to represent the support beam, and 1/2" wafer board as an interior wall covering.

Thermal Values	Heat Flow Horz.	U Value Horiz.	K Value Horiz.
Radiant Reflect™ w/Wafer Board	6.93	.144	.144
Radiant Reflect™ w/Metal Interior	6.22	.161	.161
Radiant Reflect™ Exposed to Interior	4.91*	.204*	.204*

All Thermal Values are corrected for frame loss.
* Includes thermal resistance of 1.70 for interior air film.
