Watertight Flashing Tape


Watertight® is a flexible flashing tape used around framed joinery openings as a secondary weather-resistant barrier. It is designed to prevent water penetration around window and door openings at framing junctions, and to keep any water that gets past the cladding or through the joinery from direct contact with the framing to which Watertight® has been applied. It is also used to seal the upstand of window head flashing and meter boxes with built-in flanges to the building underlay. If rigid barriers are used instead of building wrap, Watertight® can be used to flash the panels, as it can be exposed to direct sunlight for 90 days.
