Product Details

AP Breathing Sheathing

Product Long Description
Johns Manville AP™ Breathing Sheathing Polyiso Continuous Insulation board is a breathable continuous polyiso insulation, which is designed to be semi vapor permeable. AP Breathing Sheathing consists of a uniform closed-cell polyisocyanurate foam core bonded to a coated glass facer on both sides of the board. Polyiso provides one of the highest R-values per inch of any rigid insulation.

AP Breathing Sheathing is produced with an EPA-compliant hydrocarbon-based blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP); it also meets both CFC- and HCFC-free specification requirements. Polyiso is one of North America’s most widely used insulation products and has been cited by the EPA for its responsible impact on the environment.

AP Breathing Sheathing provides exceptional heat and moisture resistance to protect your building’s exterior wall assembly.
