Foam Board / Sheathing

Johns Manville Polyiso foam sheathing insulation boards provide a continuous layer of insulation to reduce thermal bridging and improve energy efficiency. Polyiso consists of a uniform closed-cell polyisocyanurate foam core and provides one of the highest R-values per inch of any rigid insulation.

With exceptional heat, moisture and air control, Johns Manville AP Foil-Faced Polyiso Foam Sheathing eliminates all major thermal bridges that cause heat loss when installed correctly.

Johns Manville AP Foil-Faced Polyiso Foam Sheathing boards are available up to RSI 5.09 (R-28) and offer a reflective foil facer on one side and a non-reflective facer on the other. AP Foil provides exceptional heat, moisture and air control and, when installed correctly, eliminates all major thermal bridges that cause heat loss. The rigid board sheathing has a one-inch layer of continuous insulation for maximum wall and worksite efficiency.
