Atlas EnergyShield® Pro 2 is composed of a Class A closed cell polyisocyanurate (polyiso glass fiber reinforced) foam core faced with a reflective 12 mil reinforced foil facer on one side and a white 12 mil reinforced acrylic-coated aluminum facer on the other. The blowing agent used to produce the polyiso foam core does not contain any CFCs, HCFCs or HFCs. EnergyShield Pro 2 has zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). EnergyShield Pro 2 combines high R-value, Class A foam core, durable aluminum facers, and water resistive barrier attributes in a high performance rigid wall insulation. EnergyShield Pro 2 is designed to be used as exterior continuous insulation (CI) or may be reversed for interior applications in compliance with NFPA 286 for interior walls only or ceilings only where a clean white surface is desirable.
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 188.8.131.52.
2“R” means resistance to heat flow. The higher the R-value, the greater the insulating power.

EnergyShield® Pro and Pro 2 are recommended for use in both commercial and residential construction (Type l through Type V) where the Class A flame spread is needed.
Common applications include:
- Exterior or interior continuous insulation (CI) in commercial and residential steel stud construction
- Exterior or interior continuous insulation (CI) for masonry or concrete wall systems, including exterior masonry cavities
- Exterior or interior continuous insulation (CI) in commercial and residential wood stud construction
- 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
- Various OEM applications
- Approved of use in attics and crawlspaces without requiring the use of a thermal barrier (ICC-ES A12, Appendix B)
- Interior exposed applications installed with white facer facing outward for interior walls only or ceilings only

EnergyShield® Pro or Pro 2 can be used as part of a WRB and potentially part of an air barrier assembly. EnergyShield® Pro and Pro 2 have 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® Pro or Pro 2 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.
