VELUX Recessed Flashings W/ Installation Productions 134x140cm EDN UK08 2000
What is included and compatibility
This kit contains everything needed for a complete recessed installation: a slate-finish flashing and BDX 2000F installation frame. It is designed specifically for VELUX UK08 roof windows and compatible Sun Tunnel systems. The 1340×1400mm dimensions are engineered to work with standard roof pitches and tile profiles commonly found in UK properties. Check your roof window model number matches UK08 before ordering, as this flashing is not compatible with other VELUX window sizes.
- Slate-finish flashing for visual consistency with typical UK roofing
- BDX 2000F installation frame included
- Sized for UK08 windows only
- Suitable for pitched roofs with standard tile or slate profiles
Choosing the right flashing for your project
Recessed flashing is the preferred choice when you want the window to integrate neatly into the roof plane rather than sitting proud of it. This approach reduces visual impact and creates a more finished appearance, particularly in refurbishment work where aesthetic consistency matters. The slate finish ensures the flashing blends with typical UK roofing materials. Use this kit for new build installations or when replacing an existing UK08 window in a pitched roof.
- Choose recessed flashing for a neat, professional roof finish
- Ideal for both new build and refurbishment projects
- Slate finish matches common UK roof materials
- Creates a weather-tight seal suitable for UK climate conditions
Pre-installation checks and preparation
Before fitting, verify that your roof window is a VELUX UK08 model and confirm the roof pitch and tile profile match standard UK specifications. Inspect the roof opening to ensure it is square and the correct size for the 1340×1400mm flashing. Check that the roof structure is sound and the surrounding tiles or slates are in good condition. Have the installation frame and flashing components laid out and inspected for any damage before work begins. Ensure you have appropriate safety equipment and access arrangements for working at height.
- Confirm your roof window is VELUX UK08 compatible
- Check roof pitch and tile profile are standard UK types
- Inspect the roof opening for correct dimensions and squareness
- Verify roof structure and surrounding materials are sound
- Arrange safe access and appropriate safety equipment
Installation overview
The recessed installation method requires the window opening to be prepared so the flashing sits flush with the roof plane. The BDX 2000F installation frame is positioned first, then the slate-finish flashing is secured to create a weather-tight seal around the window. Proper sealing and flashing are critical to prevent water ingress in UK weather conditions. This is a specialist installation task; if you are not experienced in roof work, engage a qualified installer to ensure the system performs correctly and your roof warranty is maintained.
