AIR-SHIELD_™
Self-Adhering Air/Vapor and Liquid Moisture Barrier

W R Meadows Air Shield LT 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 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.

AIR-SHIELD is packaged in rolls of 38.5″ (.97 m) x 75′ (22.86 m).  AIR-SHIELD can also be cut to desired width.
