Atlas EnergyShield^® rigid wall insulation is a closed cell polyiso foam core, faced with a reflective foil facer on the front and a non-reflective acrylic-coated facer on the back. EnergyShield^® combines high R-value, durable foil facers, and water resistive attributes in a high performance rigid insulation board.

Atlas EnergyShield^® has multiple applications from exterior or interior insulated (with a thermal barrier) sheathing to attics and crawlspaces, without requiring the use of a thermal barrier. It is a perfect fit for use over existing cladding to improve energy efficiency, as well as providing a level surface prior to installing new cladding.
