How and where to use guide
VELUX EDWS MMK06 2000 2in1 Tile Flashing - 151 x 118cm
Where to use this product
This tile flashing is designed exclusively for pitched tile roofs where VELUX roof windows are being installed. The 151 x 118cm size matches specific VELUX window models, so verify your window dimensions before ordering. The product is not suitable for flat roofs, metal roofing, or slate roofs unless specifically confirmed with VELUX technical guidance. It works on standard domestic pitched tile installations where the roof pitch and tile profile are compatible with VELUX window systems.
- Pitched tile roofs only
- Compatible VELUX roof window openings of 151 x 118cm
- Domestic and light commercial applications
- Check window model compatibility before purchase
Installation and application
The 2in1 design means the flashing and insulation layer are pre-integrated, eliminating the need to source and fit separate components. During installation, position the unit around the roof window opening to create a weathertight seal between the window frame and the roof structure. The flashing element handles water runoff and weather protection, whilst the integrated insulation layer minimises thermal bridging at the opening. Follow VELUX installation instructions carefully, as correct positioning is essential for both weatherproofing performance and thermal efficiency. Ensure the flashing sits properly under the tiles above the window and over the tiles below to maintain the roof's water shedding sequence.
- Combines flashing and insulation in one fitting operation
- Reduces on-site assembly time compared to separate components
- Position to maintain correct tile overlap and water runoff
- Secure according to VELUX technical guidance
- Verify all seals are complete before tiling around the unit
Maintenance and care
Once installed, the flashing requires minimal maintenance. Periodically inspect the seal around the window frame, particularly after severe weather, to ensure no water ingress has occurred. Check that tiles remain properly seated around the flashing edges and that no debris has accumulated in the junction between the flashing and roof surface. The integrated insulation is protected by the flashing layer and does not require separate maintenance. If any damage to the flashing is noticed, contact VELUX for repair or replacement advice rather than attempting temporary fixes.
- Inspect seals annually or after severe weather
- Clear debris from around the flashing edges
- Check tile seating remains secure
- Do not attempt to repair damaged flashing yourself
Important limitations and on-site tips
This product is sized specifically for 151 x 118cm openings; using it on incorrectly sized windows will compromise weatherproofing and thermal performance. The 2in1 design means you cannot separate the flashing from the insulation if site conditions require adjustment, so careful measurement and planning before installation is essential. Ensure the roof structure is sound and properly prepared before fitting. The product is designed for pitched roofs only and will not perform correctly on flat or low-pitch applications. Always refer to the VELUX installation manual for your specific window model, as fitting procedures may vary.
- Confirm opening size matches 151 x 118cm specification
- Not suitable for flat roofs or roofs below minimum pitch
- Prepare roof opening carefully before installation
- Consult VELUX manual for your window model
- Order additional components separately if needed
