Just like a space suit or thermos bottle the reflective surface inhibits radiant heat transfer.
Solar barrier attic.
Increasing summer energy consumption and cooling costs.
They don t however reduce heat conduction like thermal insulation materials.
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.
Srx works better than radiant barrier.
In short yes attic radiant barrier does work.
Like a space suit radiant barrier reflects the sun s heat before it can warm up the insulation in your attic.
The temperature of the attic space increases and that heat is transferred to the building below.

Unroll the radiant barrier hold in place and staple to bottom of roof joists.
Radiant barriers are utilized to reduce summer heat gain in attics.
Now there is a newer better radiant barrier product called srx superreflex.
When the insulation stays cooler your house will too.
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.
Staples should be placed 14 to 18 inches apart.
The barriers consist of a highly reflective material that reflects radiant heat rather than absorbing it.
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.
