Which Radiant Barrier Is the Best

According to the Department of Energy (DOE), a product classified as a “radiant barrier” must have a high reflectance of al least 90% and a low emittance of 10% or less.

How do I choose a radiant barrier?

According to the Department of Energy (DOE), a product classified as a “radiant barrier” must have a high reflectance of al least 90% and a low emittance of 10% or less.

What is the R-value of radiant barrier?

Radiant barrier on its own has NO R-value; R-value is attributed to materials slowing conductive heat. AtticFoil™ works to block radiant heat (97%) coming in to the attic by stapling it to the rafters, but it has no R-value.
