Owens Corning™ JointSealR® Foam Joint Tape is used to tape the joints of FOAMULAR® extruded polystyrene (XPS) thermal insulation in vertical wall applications as continuous insulation over steel or wood wall framing, or as masonry cavity wall insulation. The durable backing, coated with an aggressive acrylic adhesive offers excellent adhesion, strength, handle ability and flexibility. JointSealR® Foam Joint Tape will move along with building materials as they flex and adjust to the change in seasons, allowing it to stay in place and not create gaps in the weather barrier.
