Solar Barrier Attic

They don t however reduce heat conduction like thermal insulation materials.

Solar barrier attic.

Increasing summer energy consumption and cooling costs. Just like a space suit or thermos bottle the reflective surface inhibits radiant heat transfer. Srx works better than radiant barrier. Like a space suit radiant barrier reflects the sun s heat before it can warm up the insulation in your attic.

Staples should be placed 14 to 18 inches apart. Now there is a newer better radiant barrier product called srx superreflex. When the insulation stays cooler your house will too. April 19 2019 posted in.

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. 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. The temperature of the attic space increases and that heat is transferred to the building below.

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. Radiant barriers are installed in homes usually in attics primarily to reduce summer heat gain and reduce cooling costs. Unroll the radiant barrier hold in place and staple to bottom of roof joists. The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.
