Building: Block Wall Construction
Product: 1â€ P2000 WPR
Test Year: 2007
Conventional thinking leads us to believe that foil faced insulations will only perform on the warm side of a concrete wall. However, P2000 has been installed successfully on the cold side of concrete walls in a variety of building structures with impressive results. In December of 2007, a test was conducted to verify the effectiveness of P2000 on the exterior of a block wall under winter conditions.
A 4â€™ x 8â€™ sheet of 1â€ WPR P2000 was applied to a section of block wall using minimal fasteners.The goal was to produce a side by side comparison between the insulated and bare wall portions using infrared thermal imaging to monitor wall temperature.
â€¢ Both exterior and interior temperature profiles indicate that the transfer of heat through the block wall was significantly reduced using only 1â€ P2000
â€¢ The exterior surface temperature of the P2000 sheet was approximately the same as the air, indicating minimal heat loss in this area. Conversely, the bare block wall was approximately 6 oC warmer than the air, indicating significant heat loss.
â€¢ The interior wall area opposite the P2000 is several degrees warmer than the bare block wall area. This indicates a significantly lower heat loss when P2000 is applied.
â€¢ The temperature between the P2000 and the block wall was approximately 12 oC higher than the surrounding wall temperature, indicating a substantial resistance to heat flow at the interface of the P2000 and the wall.
