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 in R-Values up to 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 continuous insulation board allows for maximum wall and worksite efficieny.
