Tempshield® Reflective (Bubble) Post Frame R Values

R Value was calculated for the Tempshield® Reflective (Bubble) Post Frame Insulation by using the following assembly: corrugated metal exterior, 2" x 4" purlins, Tempshield® Reflective (Bubble) Post Frame 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
TempShield® w/Wafer Board 6.93 15.11 .144 .066 .144 .066
TempShield® w/Metal Interior 6.22 14.40 .161 .069 .161 .069
TempShield® 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 TempShield® installed in the walls of post frame buildings are based on testing of an assembly consisting of corrugated metal exterior, 2" x 4" girts, TempShield® Insulation, a 4" x 6" to represent the support beam, and 1/2" wafer board as an interior wall covering.

Thermal Values Heat Flow Horiz. U Value Horiz. K Value Horiz.

TempShield® w/Metal Interior 6.22 .161 .161
TempShield® 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.
