W. R. MEADOWS’ AIR-SHIELD air/vapor and liquid moisture barrier is part of a total W. R. MEADOWS system to complete the building envelope. This unique, self-adhesive membrane is protected by a special release paper that makes it strong and durable. According to the company, it remains flexible when surface mounted, will adhere to most primed surfaces at minimum temperatures of 40 degrees Fahrenheit, and provides excellent protection that won’t shrink, sag, dry out, crack or rot. The product offers resistance to punctures during installation, and its self-healing characteristics facilitate recovery if minimal damage is sustained under normal use applications. It is a roll-type product that is nominally 40 mils thick, and the membrane’s controlled thickness is fabricated from cross-laminated polyethylene bonded to specially modified asphalt.
