Radiant Barrier Roof Material

A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer because thermal energy is also transferred by conduction and convection in addition radiation radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection.

Radiant barrier roof material.

A radiant barrier can be effective with an asphalt shingle roof only when installed inside the attic either to the underside of the roof decking or to the underside of the roof rafters.
