Primary applications include cavity wall and masonry wall construction. AIR-SHIELD LMP is suitable for both new construction and retrofit applications. It may be applied to most common surfaces and integrated into various wall systems. When properly applied as a drainage plane, AIR-SHIELD LMP prohibits liquid water intrusion into the substrate.ĪIR-SHIELD LMP has been specifically formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it. AIR-SHIELD LMP exhibits excellent resistance to air leakage. Liquid Membrane Vapor Permeable Air BarrierĪIR-SHIELD LMP is a water-based air/liquid moisture barrier that cures to form a tough, seamless, elastomeric membrane. AIR-SHIELD SMP offers a controlled thickness membrane that is highly flexible with the ability to bridge cracks. It can be installed in a wide range of temperatures from 14° – 140° F (-10° – 60° C). AIR-SHIELD SMP is suitable for both new construction and retrofit applications and works equally well as an air barrier on precast concrete, cast-in-place concrete, masonry (concrete block), interior and exterior gypsum board, Styrofoam, primed steel, aluminum mill finish, anodized aluminum, primed galvanized metal, drywall, and plywood.ĪIR-SHIELD SMP can be left exposed to UV rays for up to 90 days. It may be applied to most common surfaces and integrated into various wall assemblies. AIR-SHIELD SMP is a tough, durable membrane that exhibits excellent resistance to air leakage and liquid water intrusion, while at the same time allows vapor to readily pass through to allow the wall assembly to dry.ĪIR-SHIELD SMP has been specifically formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it. Sheet Membrane Vapor Permeable Air BarrierĪIR-SHIELD SMP is a self-adhesive, vapor permeable, air/liquid moisture barrier that is designed to be fully bonded to the substrate without the use of an adhesive or primer.
