ATLAS EnergyShield Polyisocyanurate Foam Core 4' X 8'
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 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. EnergyShield is suitable for a variety of continuous insulation (CI) applications.
EnergyShield is recommended for use in residential applications as well as some commercial construction applications. Check local building codes for compliance.
Common applications include:
Exterior or interior rigid insulation (interior application requires a thermal barrier) for walls framed with wood or steel studs
Exterior or interior continuous insulation (CI) for masonry or concrete wall systems, including exterior masonry cavities
Exterior continuous insulation (CI) over wood or gypsum sheathings
Use over existing cladding to improve energy efficiency with continuous insulation (CI) and provide a level surface prior to installing a new cladding
Approved of use in attics and crawlspaces without requiring the use of a thermal barrier. (ICC-ES A12, Appendix B)
Knee wall and vaulted ceiling applications (with an approved thermal barrier)

EnergyShield can be used as part of a WRB and potentially part of an air barrier assembly. EnergyShield has passed ASTM E2357 as a component of an air barrier assembly. In these types of assemblies it is required that all joints, penetrations, and openings be taped or sealed by other means. Atlas recommends flashing EnergyShield into rough openings and other building transitions. The foil facers are compatible with most flashing or sheathing tape, joint fillers, sealants, and adhesives. Consult the product manufacturer for specific compatibility.
