TechShield radiant barrier sheathing can help homeowners conserve energy by keeping up to 97 percent of the sun's radiant heat from entering the attic. TechShield, the only radiant barrier sheathing with post-lamination incising, effectively allows moisture to escape from the foil side of the board should it get wet. Studies have shown that using a radiant barrier can effectively reduce the amount of energy required to cool the home by up to 20 percent. And TechShield radiant barrier sheathing adds no additional time or labor costs to the construction, because the foil is already laminated to the board.
