Description
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.
