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/Wafer Board | 6.93 | .144 | .144 |
| 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.
