VELUX Twin and Combination Flashings 114x118cm EKL SK06 S0312
Suitable applications and roof types
These flashings are designed specifically for flat roofing materials and work across a wide range of roof pitches, from shallow 15° pitches through to vertical 90° installations. They are particularly suited to modern flat-roof constructions and pitched roofs where the roofing material profile does not exceed 8mm in depth. The combination flashing design makes them especially valuable for multi-window installations where you need to connect adjacent VELUX windows efficiently.
- Flat roofing materials with maximum 8mm profile depth
- Roof pitches from 15° to 90°
- Single or multiple window installations with 100mm spacing between units
- New builds and retrofit applications
Installation guidance
Position the flashing brackets level with the red line marked at the top of the flashing to ensure correct alignment and optimal water drainage. The combination design allows straightforward interconnection when installing multiple windows side by side. Maintain a 100mm gap between adjacent window units to allow the interconnected flashings to function properly. Ensure the flashing sits flush against your roofing material to create an effective weatherproof seal.
- Align brackets with the red line marked on the flashing
- Maintain 100mm gap between adjacent windows for interconnected installations
- Ensure full contact between flashing and roofing material
- Check that the flashing sits level before securing
Drainage and weatherproofing
The flashing incorporates an effective rainwater drainage system that directs water away from the window frame and down the roof surface. The corrosion-proof materials ensure that the drainage channels remain clear and functional throughout the product's lifespan. Proper installation with the brackets positioned correctly is essential to maintain this drainage performance and prevent water ingress at the roof-window interface.
- Rainwater is directed away from the window frame
- Corrosion-proof materials prevent blockages and degradation
- Regular inspection recommended to ensure drainage channels remain clear
- Correct bracket positioning is critical for effective drainage
