What Is Radiant Barrier Insulation and How Does It Work

A radiant barrier reflects thermal radiation, reducing heat transfer through walls, roofs, and attics. It works by bouncing radiant heat away from the surface it protects rather than absorbing it. When installed in an attic, studies have shown a temperature reduction of as much as 30 degrees. The result is a more comfortable building and […]
