Solar Barrier Attic

The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.

Solar barrier attic. When the insulation stays cooler your house will too. On any given hot day the temperature on shingles can range from 160 to 190 so the slight increase from the barriers are insignificant and does not quicken the degradation of your shingles. In short yes attic radiant barrier does work. Now there is a newer better radiant barrier product called srx superreflex.

Radiant barriers may increase the temperature of your exterior roofline on a hot summer day by 2 to 5 as it reflects the sun s rays from entering into the attic but it will not cook your shingles. Just like a space suit or thermos bottle the reflective surface inhibits radiant heat transfer. Unroll the radiant barrier hold in place and staple to bottom of roof joists. Srx works better than radiant barrier.

Increasing summer energy consumption and cooling costs. Radiant barriers are utilized to reduce summer heat gain in attics. In an open framed attic it is generally easiest to install the strips of radiant barrier roof material across the attic perpendicular to the direction of the roof joists overlapping each run by about 2 inches.

Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction. The temperature of the attic space increases and that heat is transferred to the building below. They don t however reduce heat conduction like thermal insulation materials.
