Weyerhaeuser Radiant Barrier Sheathing (RBS) comes pre-fabricated with a reflective foil layer that blocks more than 97% of the sun’s radiant energy, minimizing heat transfer through the roof and insulation to interior living spaces. As an added plus, Weyerhaeuser RBS can even help keep non-air-conditioned, uninsulated rooms like garages, workshops and porches cooler, increasing a home’s usable space.

Installing RBS is an efficient, cost-effective way to help keep interior living spaces comfortable while saving energy costs. Weyerhaeuser RBS provides all these benefits with no additional labor or material hassles. Thanks to an innovative wood-resin combination, every Weyerhaeuser RBS panel is manufactured flat, installs flat and stays flat, and has been engineered to precise specifications to resist problems like cupping, warp and sag. The radiant foil layer is perforated for ventilation to protect against condensation and moisture build-up.
