PARSIPPANY, N.J.  — With an increasing focus on sustainable building and environmental practices, energy code requirements in many parts of the country continue to change. Because of this, the need for increased R-value at the sidewalls is more important than ever. GAF, North America’s largest roofing manufacturer, is proud to introduce a product to help meet these requirements – ThermaCal® Wall Insulation Panels.
Designed to add insulation value to the outside of exterior sidewalls while serving as a nailable base for exterior sidewall coverings,* ThermaCal® Wall Exterior Wall Insulation Panels help reduce heat loss and cold drive into the living space of a home. They can also help reduce associated energy costs and meet the increased R-value energy code requirements being adopted in certain climate zones. ThermaCal® Wall Panels attach to structural exterior sidewalls and can be fastened to outside wall sheathing, metal, or masonry walls.
Insulating only the cavity wall leaves up to 25% of the wall area underinsulated by studs, creating a thermal bridge. Installing ThermaCal® Wall Panels helps eliminate thermal bridging by covering the studs while adding continuous insulation to the rest of the wall. The panels also help minimize heat loss through their exclusive tongue-and-groove design.   
Supporting the GAF focus on reducing hassles for contractors, ThermaCal® Wall Panels are constructed with cut-back sheathing, allowing for precision fit and clearance for sheathing expansion. They also offer versatility and can be used on residential or commercial exterior sidewall applications without the need for interior alterations.
