Atlas EnergyShield Wall insulation is composed of a closed cell polyisocyanurate (polyiso) foam core, faced with tri-laminate foil. The blowing agent used to produce the polyiso foam core does not contain any CFCs, HCFCs or HFCs. EnergyShield is suitable for a variety of continuous insulation (CI) applications. EnergyShield has zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). EnergyShield combines high R-value, durable foil facers, and water resistive attributes in a high performance rigid wall insulation.
