Airlok® Sheet 400 NP

Airlok® Sheet 400 NP  is a 40-mil, 36” x 75’ laminated, modified-asphalt, self-adhesive, non-permeable sheet membranes bonded to a cross-laminated polyethylene sheet designed for air and moisture applications with a 60-day UV exposure. Rubberized-asphalt properties allow for self-sealing around fasteners, sealing of laps, and adhesion to the substrate at ambient application temperatures of 25°F (-4°C) and rising.

Each of our sheet products come with complementary cut sizes for flashing applications to a similar specification to our sheet membranes. As an alternative, we have a series of fluid-applied flashing and detail products.
