York HomeSeal 4 in. W X 900 in. L Asphalt/Polyethylene Flashing Black

York’s high adhesion formula for the HomeSeal window and door tape can be used to seal cracks, punctures or variations in foundations or masonry walls. It also provides a superior barrier to air and moisture at construction joints and fittings around doors and windows. Its tough, high-density cross laminated polyethylene film resists physical damage and its proprietary, modified asphalt gives you the waterproofing effectiveness of traditional modified bitumen products along with a unique combination of high strength, low temperature adhesion and high temperature stability.
