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 glass facers are compatible with most standard joint fillers, sealants and adhesives. Consult the product manufacturer for specific compatibility.
