MasterSeal AWB 660 vapor permeable air-/water-resistive barrier(Formerly Enershield HP)MasterSeal AWB 660 descriptionMasterSeal AWB 660 (High Permeability) is a one component fluid-applied vapor permeable air/ water-resistive barrier based on Silica Fortified Rubber chemistry. This resilient water-resistant coating may be roller-, brush-, trowel-, or spray-applied directly to approved wall substrates. It provides excellent secondary moisture protection to most wall claddings. MasterSeal AWB 660 complies with the air barrier impermeability requirements of the Massachusetts Energy Code. LimitationMasterSeal AWB 660 should not be used for below grade applications or on surfaces subject to water immersion. Recommended usesMasterSeal AWB 660 is used as an air/water-resistive barrier over the following exterior wall substrates:
MasterSeal AWB 660 provides excellent secondary moisture protection behind many wall claddings including brick, siding, metal panels, EIFS and stucco. (A slip-sheet is required for stucco claddings.) MasterSeal AWB 660 features
