VELUX Standard Flashings 78x140cm EDW MK08 0000
Typical applications and suitability
These flashings are intended for flat roof installations where a VELUX EDW rooflight penetrates the roof surface. They work with standard timber structural grades F16 and F24, making them suitable for most domestic and light commercial flat roof projects. The plastic construction resists rot and insect damage, providing long-term durability in exposed roof conditions. Always verify that your rooflight is the VELUX EDW model before ordering, as flashings are profile-specific and will not fit other rooflight types.
- Flat roof installations only
- VELUX EDW rooflights exclusively
- Timber grades F16 and F24
- Domestic and light commercial use
Installation methods and on-site practice
The flashings can be installed using either screw fixing or adhesive application, offering flexibility depending on site conditions and preference. For screw fixing, position the flashing around the rooflight frame and secure through pre-drilled holes into the timber substrate. For adhesive application, use a suitable roofing adhesive and apply to the underside of the flashing before pressing firmly into place. Ensure the rooflight frame is clean and dry before installation. Follow current site practice for flat roof work and refer to the manufacturer's installation guidance provided with the product.

Maintenance and limitations
The plastic construction requires minimal maintenance beyond routine roof inspections. Check the seal around the flashing periodically, particularly after severe weather, to ensure it remains watertight. Do not use abrasive cleaning methods on the plastic surface. These flashings are designed for flat roof use only and are not suitable for pitched or sloped roof installations. The 78cm × 140cm profile is fixed to the VELUX EDW rooflight dimensions; do not attempt to use with other rooflight models or sizes.
