TECHNO TEC-WT150 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.

Available in three size widths: 75mm, 150mm, and 200mm

(also marketed as FrameFlash™)

Watertight® can be exposed beyond 90days, but as building wraps need to be replaced after 60 days’ exposure, BRANZ has recommended a 90-day maximum. Watertight® is a multi-layered 1.2mm thickflexible flashing tape. The top layer is pure aluminium, and the second layer is made
of high-strength polyethylene raffia. The third layer is self-adhesive bitumen improved for New Zealand conditions, while the last layer is made of siliconized polyethylene
