VELUX EDP MK06 2000 Pro+ Standard Flashings W/ Installation Products 78x118cm
Suitable applications and roof types
This flashing kit is designed specifically for plain tile roof installations where your VELUX roof window or Sun Tunnel system requires weather-tight integration. The system accommodates plain tiles up to 14mm in thickness, which covers most standard UK plain tile specifications. Use this flashing for both new roof installations during construction and for refurbishment work where you are retrofitting a VELUX window into an existing plain tile roof. The 780×1180mm dimensions are sized to match the MK06 VELUX window format.
- Plain tile roofs only, not suitable for slate, interlocking tiles, or other roof coverings
- Maximum tile thickness 14mm—check your existing tiles before ordering
- Compatible with VELUX roof window and Sun Tunnel product ranges
- Suitable for new build and refurbishment projects
Installation overview and key steps
The flashing kit includes BDX and BFX installation products that work together to create a complete weather-tight seal around your VELUX window opening. Begin by preparing the roof opening to the correct dimensions for the MK06 format. Position the flashing carefully to ensure it sits flush with the surrounding plain tiles, allowing water to run off naturally down the roof slope. The included installation products are engineered to integrate the flashing with both the window frame and the roof structure, creating a continuous weather barrier. Ensure all components are properly secured and sealed according to VELUX installation guidance before re-tiling around the flashing edges.
- Prepare roof opening to MK06 specifications before fitting
- Use BDX and BFX products as supplied in the kit for complete integration
- Position flashing to maintain natural water run-off down the roof slope
- Secure and seal all components before completing tile work around the flashing
Limitations and important considerations
This flashing is engineered for plain tile roofs only and will not perform correctly on slate, interlocking tiles, or other roof coverings. The 14mm maximum tile thickness specification is a critical limit—using this flashing on thicker tiles will compromise the weather-tight seal and may cause water ingress. The kit is sized for MK06 format VELUX windows and Sun Tunnel systems; do not attempt to use this flashing with other window sizes or manufacturers' products. Proper installation is essential to performance; if you are unfamiliar with roof window installation, consult VELUX technical guidance or engage a qualified installer.
- Not suitable for slate, interlocking, or non-standard roof tiles
- Do not use on tiles thicker than 14mm
- Sized for MK06 VELUX windows and Sun Tunnel systems only
- Improper installation will compromise weather-tightness and durability
On-site handling and maintenance
Store the flashing kit in a dry location on site until installation to prevent damage to the BDX and BFX components. Handle the flashing carefully to avoid denting or bending, which could affect the seal. Once installed, the flashing requires no routine maintenance beyond standard roof inspection. Check the flashing annually as part of your roof maintenance schedule, particularly after severe weather, to ensure all seals remain intact and no debris has accumulated around the window frame. If you notice any water staining or damp around the window, inspect the flashing seal immediately and contact VELUX technical support if repairs are needed.
