SDS

Product Guide

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 continuous insulation board allows for maximum wall and worksite efficiency.

Advantages

Thermally Efficient: Effective resistance to heat transfer, with R-values up to R-28 (RSI-5.09).
Water-Resistant Barrier: Meets the NBC acceptance criteria CCMC-13104-L.
Vapour Barrier: Class I vapour retarder at 25mm (1”).
Lightweight: Easy to handle and can be cut with a utility knife or saw.
