VELUX Recessed Flashings W/ Installation Productions 134x140cm EDJ UK08 2000
Typical applications
This flashing kit is intended for installation with VELUX UK08 roof windows and compatible Sun Tunnel systems. It works on pitched tile roofs where a recessed, weather-tight integration is required. The system is equally suitable for new build installations where the roof structure is being completed, or for refurbishment projects where an existing roof window needs replacing or upgrading.
- New build residential and commercial pitched roof projects
- Refurbishment and replacement of existing UK08 roof windows
- Integration with VELUX Sun Tunnel daylight systems
- Tile roof applications requiring neat, professional finish
Installation and setup
The BDX 2000F installation frame and 90mm tile flashing work together to create a complete sealing system. The recessed design allows the flashing to sit neatly within the roof plane, minimising visual disruption whilst maintaining weather protection. The kit is pre-engineered to reduce on-site assembly time. Ensure the roof opening dimensions match the 1340×1400mm (W×H) specification before commencing work. The flashing must be positioned to allow proper water run-off and integrated with your roof tiling sequence to prevent water pooling or bypass.
- Verify roof opening matches 1340×1400mm dimensions
- Install the BDX 2000F frame first to establish the structural opening
- Position the 90mm tile flashing to integrate with roof tile courses
- Ensure proper water run-off gradient and no pooling areas
- Seal all joints and edges to maintain weather-tight integrity
Maintenance and on-site tips
Once installed, the flashing requires minimal maintenance but should be inspected annually, particularly after severe weather. Clear any debris from the flashing edges and roof surface to maintain proper water drainage. The engineered finish is designed to withstand typical UK roof conditions, but avoid walking directly on the flashing or placing heavy loads on the window frame. If refurbishing an existing installation, ensure the old flashing is completely removed and the roof structure is sound before fitting this kit.
- Inspect annually for debris accumulation and clear gutters
- Avoid walking on or placing loads on the window frame
- Check seals and joints after severe weather events
- Remove old flashing completely before installation on refurbishment projects
- Ensure roof structure is sound and level before fitting
