GAF North America’s ThermaCal Exterior Wall Insulation Panels eliminate thermal bridging by covering the studs and adding continuous insulation to the rest of a wall. The panels minimize heat loss with a tongue-and-groove design, attach to structural exterior sidewalls and can be fastened to outside metal, wall sheathing and masonry walls. ThermaCal Exterior Wall Insulation Panels are constructed with cut-back sheathing designed for precision fit and clearance for sheathing expansion.
