Radiant Barrier System
A radiant barrier system, or RBS, is installed primarily to improve comfort and reduce energy use for mechanical cooling in hot climates. A radiant barrier system is comprised of a sheet of reflective foil placed next to an air space, such as an attic. A properly installed RBS can block up to 95% of the heat transfer from the roof to the attic insulation, resulting in a cooler living space and less cooling load.
Energy bill savings resulting from an RBS will vary, but studies show that typical savings are between 8-12% of annual cooling costs.
