LP TechShield is America’s #1 selling radiant barrier brand. Created by laminating a layer of aluminum to our OSB sheathing, LP TechShield Radiant Barrier Sheathing installs like regular roof sheathing. Yet by helping to block heat in the sheathing from entering the attic, it can reduce air conditioning costs as much as 17% in your top floor units. LP TechShield Sheathing is made using our patented post-lamination foil incising process, which allows it to dry from construction moisture more quickly than other radiant barrier panels. Backed by a 20-Year Transferable Limited Warranty, LP TechShield products have earned the U.S. Government’s ENERGY STAR® certification. To learn more about this product click here.
