Sheathing eliminates thermal bridging
GAF has announced EnergyGuard™ Polyiso Insulated Sheathing to eliminate thermal bridging in new construction and retrofit applications.
EnergyGuard Polyiso Insulated Sheathing is manufactured with Environmental Protection Agency-compliant blowing agents containing no chlorofluorocarbons or hydrochlorofluorocarbons and reportedly reduces energy costs because of its high R-value. The 4- by 8-foot boards are available in 1/2-, 3/4-, 1- and 2-inch thicknesses for a range of applications.
