W.R. Meadows Airshield

SKU: M15115218

AIR-SHIELD self-adhering air/vapour 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 membranes controlled thickness is fabricated from cross-laminated 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. AIR-SHIELD can also be used as a transition membrane to provide protection against water infiltration in critical detail areas, such as window and door openings, deck-to-wall intersections, corner boards, wall-to-wall tie-ins, foundation sill plates, sheathing panel seams, under stucco finishes, masonry walls, and other non-roof detail areas.

  • Low permeability – prevents the transmission of air and inhibits moisture vapor through porous building materials.
  • Provides a complete above-grade air, vapour, and water barrier on a variety of construction materials.
  • Controlled thickness membrane is ideal for air barrier applications.
  • Cross-laminated polyethylene film has excellent tensile strength, elongation, and tear resistance.
  • Modified membrane is flexible at low temperatures.
  • Excellent adhesion to prepared substrates of 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.
  • Self-sealing around fasteners
  • No flame required.
  • Low-temperature version also available – can be applied at temperatures between 20˚ F (-7˚ C) and 60° F (16° C).
  • AIR-SHIELD XLT can be applied at minimum temperatures of 0° F (-18° C).
