Description

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.

Panel sizes are 4ʹ by 8ʹ or 4ʹ by 9ʹ. Panels can be supplied in nominal 16ʺ or 24ʺ widths for use in masonry cavity wall applications. Custom sizes are also available.

1Conditioned thermal values were determined by ASTM Test Method C 518 at 75° mean temperature. Test specimens were conditioned in accordance with procedures outlined in ASTM C1289, Section 11.1.2.1.
2“R” means resistance to heat flow. The higher the R-value, the greater the insulating power.

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)
  • Insulation for use in tilt-up wall panels
  • Under slab insulation
  • Various OEM applications
