The configuration of weather resistive barriers and/or air barriers used in conjunction with EnergyShield® Ply Pro is the responsibility of the designer.
Atlas recommends sealing into rough opening flashing and to other portions of the building, including the roof and below grade. Atlas EnergyShield® Ply Pro foil facers are compatible with most standard joint fillers, sealants and adhesives. Consult the product manufacturer for specific compatibility.
