Airlok® Sheet 200 BU/NP is a 28-mil, 100' laminated butyl, that is a self-adhesive, non-permeable sheet membrane bonded to a cross-laminated polyethylene sheet designed for air and moisture applications. It provides a 60-day UV exposure and with a service/performance temperature range up to 240°F. The butyl properties allow for self-sealing around fasteners, sealing of laps, and adhesion to the substrate at ambient application temperatures 20°F (-7°C) and rising. |
