DEWITT?S ThruWall is a proprietary, self-adhesive composite membrane, uniquely combining high strength, low temperature adhesion and high temperature stability into a superior barrier to limit air and moisture transmission. A tough 8 mil cross laminated polyethylene film forms a resilient barrier against physical damage and water migration. The 32 mils (0.8mm) of proprietary modified asphalt offers the waterproofing effectiveness of traditional modified bitumen products while introducing a novel combination of low temperature adhesion and high temperature stability.
Available in 12″, 18″, 24″ and 36″ widths; 75′ length
