VELUX Standard Flashings 114x118cm EDW SK06 0000
What this product is for
This flashing is an essential weatherproofing component that sits between your roof structure and a VELUX EDW skylight or roof ventilator. It creates a sealed barrier that prevents rainwater and wind-driven moisture from entering the building at the roof penetration point. The flashing also maintains an air-tight seal, which is important for thermal performance and condensation control in timber frame buildings.
- Creates weather-resistant seal around roof ventilators and skylights
- Maintains air-tight performance in timber frame construction
- Protects the roof-to-ventilator junction from water ingress
- Accommodates roof pitch variations across multiple configurations
Compatibility and sizing
This flashing is specifically designed for VELUX EDW skylights and compatible with standard roof ventilators. The 114×118cm size (approximately 4 feet by 3.7 feet) suits a range of roof configurations and pitches. Before ordering, confirm that your skylight or ventilator model is EDW compatible and that your roof opening dimensions fall within the coverage provided by this flashing size. Check your existing installation documentation or the ventilator packaging to verify compatibility.
- Size: 114×118cm
- Compatible with VELUX EDW skylights
- Suitable for standard roof ventilators
- Designed for timber frame construction
Pre-installation checks
Before fitting, inspect the flashing for any damage or defects in the plastic or weather-resistant coating. Ensure your roof opening is clean and free from debris, old sealant, or damaged roofing material. Check that the roof pitch and opening dimensions are compatible with this flashing size. Have all necessary fixings, sealants, and roofing materials ready before you begin installation. If replacing an existing flashing, carefully remove the old unit and clean the roof surface thoroughly.
- Inspect flashing for damage to plastic or weather-resistant finish
- Clean roof opening and remove old sealant or debris
- Verify roof pitch compatibility
- Gather fixings and sealants before starting work
Installation and performance
The flashing must be securely fixed to the roof structure and sealed around all edges to maintain its weather-resistant and air-tight properties. Proper installation is critical to prevent water ingress and maintain thermal performance. The durable plastic construction is designed to withstand UK weather conditions, but correct fitting and sealing are essential for long-term performance. Follow the manufacturer's installation instructions carefully, paying particular attention to roof pitch accommodation and edge sealing.
- Secure flashing firmly to roof structure
- Seal all edges to maintain weather resistance and air-tightness
- Ensure proper accommodation of roof pitch
- Use appropriate sealants and fixings for timber frame construction
