AIR-SHIELD: Designing for the 21st Century
W. R. MEADOWS is proud to offer the AIR-SHIELD line of sheet-applied air barriers. These self-adhesive membranes are designed to control air leakage and moisture movement in all types of wall assemblies. AIR-SHIELD membranes are strong, durable and remain flexible, even in cold temperatures (see our low-temp products). AIR-SHIELD will not shrink, sag, dry out, crack, or rot, and offers excellent resistance to punctures during installation. The self-gasketing characteristic provides continued protection if penetrated by fasteners.
NEW FROM W. R. MEADOWS – AIR-SHIELD SMP
New from W. R. MEADOWS comes AIR-SHIELD SMP sheet membrane vapor permeable air/liquid moisture barrier. It is a self-adhesive membrane that is designed to be fully bonded to the substrate without the use of an adhesive or primer, saving time and money by removing this additional step. AIR-SHIELD SMP is tough, durable, and exhibits excellent resistance to air leakage and liquid intrusion, while at the same time allowing the wall assembly to dry through its vapor permeable material.
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.
AIR-SHIELD SMP can be left exposed to UV rays for up to 90 days. It can be installed in a wide range of temperatures from 14° – 140° F (-10° – 60° C). AIR-SHIELD SMP offers a controlled thickness membrane that is highly flexible with the ability to bridge cracks.
Air Barrier White Paper
The rationale for non-permeable air barriers (fluid-applied or self-adhered sheet) is based on a number of factors. The most notable of these is the code-driven mandate for exterior continuous insulation in many climate zones. This white paper explains how this decision is made based on many factors, including insulation, the International Building Code, climatic conditions, etc.
