York HomeSeal™ is a proprietary, self-adhering 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 5mil (0.1mm) high density polyethylene film forms a resilient barrier to physical damage.  The 15 mils (0.9mm) 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.

York HomeSeal™ is self-adhering and cold-applied.  No special adhesive, heat or equipment are necessary to install York HomeSeal™.
