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.
