Air-Shiled XLT winter grade. AIR-SHIELD XLT can be applied at minimum

Additional Information

AIR-SHIELD self-adhering air/vapor and liquid moisture barrier is part of a total W. R.
MEADOWS system to complete the building envelope. It is a roll-type product that is
nominally 40 mils thick. The membrane's controlled thickness is fabricated from crosslaminated
polyethylene bonded to specially modified asphalt. ? This unique, self-adhesive membrane, protected by a special release paper, is strong and durable. It remains flexible when surface mounted and will adhere to most primed surfaces at minimum temperatures of 40 ? F (4 ? C). The membrane provides excellent protection as a tough barrier that won't shrink, sag, dry out, crack or rot. It offers excellent resistance to punctures during installation. The self-healing characteristics of AIR-SHIELD facilitate recovery if minimal damage is sustained under normal use applications, i.e. when penetrated with self-tapping screws or nails.


AIR-SHIELD should be stored palletized and protected from rain and/or physical damage. Do not store at temperatures above 90 ? F (32.2 ? C) for extended periods of time. Do not leave membrane exposed to direct sunlight. Do not double-deck pallets. Store away from sparks or flames. Outdoors, store AIR-SHIELD on pallets and completely cover.


AIR-SHIELD self-adhering air/vapor and liquid moisture barrier is designed for a variety of uses. ?
Primary applications include cavity wall and masonry wall construction. AIR-SHIELD works equally well as an air and/or vapor 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 provides an effective barrier to air exfiltration and infiltration, reducing condensation within the wall assembly and increasing efficiency of a building’s mechanical system. Wet insulating materials lose much of their R-factor performance ?characteristics, reducing the energy efficiency of the structure. W. R. MEADOWS thermal and moisture protection products play a key role in maintaining the structure’s energy efficiency and aiding in the integrity of other structural systems, such as insulation.
