Product Description

Atlas EnergyShield CGF (formerly Rboard®) is composed of a closed cell polyisocyanurate (polyiso) foam core, faced with a non-reflective coated glass-mat facer on both sides.
Atlas EnergyShield CGF combines high R-value, enhanced durability from two coated glass-mat facers, and water resistive attributes in a high performance rigid wall insulation.

Manufacturer Design Notes

EnergyShield® CGF can be used as part of a WRB and potentially part 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® CGF into rough openings and other building transitions. The coated glass-mat facers are compatible with most flashing or sheathing tape, joint fillers, sealants, and adhesives.
