XtremeFlashing™ is a self-adhering, self-sealing waterproofing tape designed for use around windows, doors, building seams and in general construction. It is composed of a white polymer film that is coated with an aggressive Broad Temperature Spectrum (BTS™) asphalt adhesive. A release liner protects the adhesive and is removed as the tape is installed.
The BTS™ adhesive self-seals around punctures such as nails and staples. This advanced system bonds to all common building and window materials and seals around fasteners to prevent damage caused by water penetration
