Thermostat® oriented strand board (OSB) radiant barrier roof sheathing is designed for roof sheathing applications, reflecting up to 97% of the sun's radiant heat – and keeping it from being absorbed into the attic of your home. That means you can maintain indoor comfort while potentially lowering cooling energy consumption.
Backed with a specially designed aluminum foil/craft paper laminate, this high-quality Georgia-Pacific OSB sheathing is installed foil side down facing into the attic space. Since aluminum foil is highly reflective, up to 97% of the radiant heat is reflected from entering the attic space.

Studies have shown that radiant barriers can reduce cooling energy consumption by up to 17%, depending on the design of the building, insulation levels and other factors. Thermostat OSB radiant barrier sheathing can lower peak attic temperatures up to 30°F by reducing summer radiant heat gain in the attic. Since less heat is transferred into living areas through the ceiling, indoor temperatures stay cooler and more comfortable while helping your cooling system operate more efficiently.
