WIN Outside
WIN Outside was developed for the exterior sealing of window connection joints. The tape is windtight and driving-rain resistant, while its high vapour permeability supports moisture release from the joint area.
- Driving-rain resistance up to 600 Pa protects the connection joint against wind-driven rain
- High vapour permeability supports moisture release from the joint area
- Protects the connection joint against air ingress from outside
- Fully self-adhesive for fast and secure application on different substrates
