Solar barrier attic.
They don t however reduce heat conduction like thermal insulation materials.
When the insulation stays cooler your house will too.
Unroll the radiant barrier hold in place and staple to bottom of roof joists.
Staples should be placed 14 to 18 inches apart.
Just like a space suit or thermos bottle the reflective surface inhibits radiant heat transfer.
The temperature of the attic space increases and that heat is transferred to the building below.
We only say radiant barrier doesn t work because we know of a product that works even better and can save you over twice as much as current radiant barrier technology.
The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.
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.
In short yes attic radiant barrier does work.
Now there is a newer better radiant barrier product called srx superreflex.
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.
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.
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.
Srx works better than radiant barrier.
Increasing summer energy consumption and cooling costs.
