VELUX Twin and Combination Flashings 134x140cm EKL UK08 S0312
Typical applications
These twin and combination flashings are designed for use around roof penetrations on flat roofs, around skylights and ventilation units. They are suitable for both new installations and retrofit work where VELUX products are being installed. The flashings create a critical weatherproofing layer that prevents water ingress around the edges of roof-mounted equipment.
- Flat roof installations with skylights or ventilation units
- Sealing around VELUX roof windows and accessories
- Weatherproofing roof penetrations on commercial and residential properties
- Use as part of a complete VELUX roofing system
Installation and adjustment
The twin flashing design allows for easy installation and adjustment on site. Position the flashing around the roof penetration to ensure water will run off the roof safely. The plastic construction provides flexibility for minor adjustments during fitting. Secure the flashing using suitable fixings appropriate for your roof type and substrate. Ensure the flashing sits flush and level to prevent water pooling or running back towards the penetration.
- Check dimensions (134cm x 140cm) match your roof opening before installation
- Position flashing to direct water away from the penetration
- Use appropriate fixings for your roof material and construction
- Ensure the flashing is level and sits flush with no gaps
Maintenance and durability
The durable plastic construction is designed to withstand exposure to weather and UV. Inspect flashings periodically to ensure they remain properly seated and that no debris has accumulated around the edges. Clear any leaves, moss or dirt that could impede water drainage. Check that fixings remain secure and that the seal around the penetration has not been compromised.
- Inspect flashings regularly for debris or damage
- Clear leaves and dirt from around the flashing edges
- Check that fixings remain tight and secure
- Verify the seal remains intact and watertight
On-site tips and limitations
Always confirm product dimensions against your project specification before ordering, as these flashings are sized specifically for UK08 applications. The twin flashing design is compatible with VELUX roofing systems, so ensure you are using complementary VELUX products for a complete installation. The plastic material is durable but should be handled carefully to avoid damage during transport and installation. Do not force the flashing into position; minor adjustments should be achievable due to the flexible design.
- Verify UK08 sizing matches your roof opening exactly
- Use only with compatible VELUX products for best results
- Handle plastic construction carefully to avoid damage
- Do not force flashing into position; adjust gently for proper fit
