VELUX EDP UK08 2000 Pro+ Standard Flashings W/ Installation Products 134x140cm
Suitable applications and roof types
This flashing kit is designed exclusively for single plain tile roofs with tile thickness up to 14mm. The 1340×1400mm aperture accommodates standard UK08 VELUX roof window and Sun Tunnel dimensions. It is appropriate for new build projects where roof structure is being installed, and for refurbishment work where existing roof windows are being replaced or new openings created. Do not use this kit on interlocking tiles, slate, or tile thicknesses exceeding 14mm, as the flashing profile is engineered specifically for single plain tile profiles.
- Single plain tile roofs only, maximum 14mm tile thickness
- Compatible with VELUX roof window and Sun Tunnel ranges
- UK08 aperture size: 1340×1400mm
- Suitable for new build and refurbishment applications
Installation overview and key steps
The kit includes BDX and BFX installation products which support a neat, professional fit and weather-tight seal. Installation involves positioning the flashing unit around the roof window aperture, securing it to the roof structure, and integrating it with the surrounding tile work. The included installation products are essential components of the system and must be used as specified to ensure proper performance. Careful alignment of the flashing with the roof pitch and tile courses is critical to prevent water ingress and maintain visual consistency with the existing roof.
- Use all included BDX and BFX installation products as part of the complete system
- Ensure flashing is level and properly aligned with roof pitch and tile courses
- Secure flashing to roof structure according to VELUX installation instructions
- Integrate flashing edges with surrounding tiles to create continuous weather protection
Limitations and important considerations
This flashing kit is designed for single plain tiles only and will not perform correctly on other tile types or thicknesses. The maximum tile thickness of 14mm is a critical specification; using this kit on thicker tiles will compromise the weather-tight seal and may cause water pooling or leakage. The aperture size is fixed at 1340×1400mm and is not adjustable, so it must match your VELUX window dimensions. Professional installation is strongly recommended to ensure the flashing integrates properly with the roof structure and surrounding tiles.
- Not suitable for interlocking tiles, slate, or tiles exceeding 14mm thickness
- Fixed aperture size cannot be modified
- Professional installation recommended for optimal weather performance
- Flashing must be integrated with surrounding tile work to prevent water ingress
On-site handling and maintenance
Store the flashing kit in a dry location on site prior to installation to prevent damage to the included BDX and BFX components. Once installed, the flashing system requires no special maintenance beyond routine roof inspection. Periodically check that tiles around the flashing remain secure and that no debris has accumulated at the flashing edges, particularly in gutters or valleys. Any damage to the flashing or sealant should be addressed promptly to maintain weather protection.
- Store kit in dry conditions before installation
- Inspect flashing and surrounding tiles periodically for damage or debris
- Ensure tiles remain secure around flashing edges
- Address any damage to flashing or sealant promptly
