W R Meadows AIR SHIELD SMP

W R Meadows AIR SHIELD SMP

Sheet Membrane Vapor Permeable Air Barrier

DESCRIPTION
W R Meadows AIR SHIELD SMP is a self-adhering, vapor permeable, air/liquid moisture barrier that is designed to be fully bonded to the substrate without the use of an adhesive or primer. 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.

USES
AIR-SHIELD SMP has been specifically formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it.   It may be applied to most common surfaces and integrated into various wall assemblies. 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.

FEATURES/BENEFITS

• When properly applied, helps reduce air and moisture intrusion.
• Bonds easily and securely to a variety of building materials – no primer required.
• Excellent adhesion – remains firmly bonded to the substrate.
• High vapor permeability – allows the transmission of moisture vapor through porous building materials.
• Controlled thickness.
• Highly flexible – bridges cracks, which may form in the substrate.
• Can be left exposed to UV for a maximum of 90 days.
• Tough, durable membrane helps resist punctures and tears during the installation process.
• Sheet-applied – no costly spray equipment or enhanced protective gear needed during installation.
• Can be installed in a wide range of temperatures.
