VELUX Recessed Flashings 134x140cm EDJ UK08 0000
Typical applications and installation locations
Recessed flashings are installed around roof windows to create a weather-tight seal between the window frame and the surrounding roof covering. They are used in pitched roof installations where the window sits within the roof plane rather than projecting above it. The flashing sits beneath the upper roof tiles or slates and above the lower ones, directing water away from the window frame and into the roof drainage system. These flashings are essential in both new build installations where roof windows are being incorporated into the design, and in repair or replacement scenarios where existing windows need re-flashing.
- New build pitched roof installations with integrated roof windows
- Roof extensions incorporating VELUX timber windows
- Replacement of existing roof window flashings during repairs or upgrades
- Domestic and light commercial roofing applications
Installation and fitting requirements
Correct installation is critical to ensure the weather-tight performance of the flashing. The flashing must be positioned so that it sits securely within the roof structure, with the upper edge tucked beneath the roof covering above the window and the lower edge positioned above the roof covering below. The recessed design ensures a snug fit around the EDJ UK08 0000 window frame. Proper alignment and securing of the flashing prevents water from running behind it and into the building fabric. Installation should follow the manufacturer's guidance to ensure the seal remains effective throughout the product's lifespan.
- Ensure the window frame is square and level before fitting the flashing
- Position the flashing so upper edge sits beneath upper roof tiles or slates
- Secure the flashing firmly to prevent movement during roof covering installation
- Check that all edges are properly sealed and no gaps remain around the frame
- Allow adequate overlap with roof covering materials for effective water shedding
Durability and weather resistance
These flashings are manufactured from durable, weather-resistant materials specifically engineered to withstand prolonged exposure to the elements. The construction resists deterioration from UV radiation, temperature fluctuations, rain, and wind, ensuring a long service life. The material's resistance to corrosion and degradation makes it suitable for use in all UK climate conditions. Proper installation and maintenance of the flashing will maximise its durability and prevent premature failure.
- Material resists UV damage and weathering over extended periods
- Durable construction prevents water ingress and associated damage to roof structure
