METAL CEILING
To achieve R value in the ceiling, Tempshield® Reflective (Bubble) Insulation was tested using the following assembly: a corrugated metal exterior, 1/2″ extruded polystyrene thermal breaks 5′ on center, TempShield® Reflective (Bubble) Insulation, and 8″ Z purlins commonly used in metal buildings.
| Thermal Values | Heat Flow Up | Heat Flow Down | U Value Up | U Value Down |
|---|---|---|---|---|
| TempShield® w/Wafer Board | 5.02 | 7.93 | .199 | .126 |
| TempShield® w/Metal Interior | 4.29 | 7.29 | .233 | .137 |
| TempShield® Exposed to Interior | 3.63* | 7.26* | .275* | .138* |
All Thermal Values are corrected for frame loss.
* Includes thermal resistance of 1.32 UP and 4.55 DOWN for interior air film.
WALLS
To achieve R value in the walls, Tempshield® Reflective (Bubble) Insulation was tested using the following assembly: a corrugated metal exterior, 1/2″ extruded polystyrene thermal breaks, TempShield® Reflective (Bubble) Insulation, 8″ Z purlins, and 1/2″ wafer board to represent an interior finished wall.
| Thermal Values | Heat Flow Horiz. | U Value Horiz. |
|---|---|---|
| TempShield® w/Wafter Board | 5.45 | .183 |
| TempShield® w/Metal Interior | 4.77 | .210 |
| TempShield® Exposed to Interior | 4.50* | .222* |
*Includes thermal resistance of 1.70 for interior air film.
