Butyl Waterproof Flashing Tape is an effective solution made with a combination of flexible butyl adhesive and an aluminium foil backing. This structure makes this tape useful in sealing joints and openings exposed to moisture and weather. Waterproof butyl flashing tape adjusts well around the edges, corners and uneven areas. This is why it works well with windows, roofing, doors, skylights and other common construction works. The self-adhesive butyl waterproof flashing tape design supports easy installation. No separate adhesive is needed to complete it.
