Fixing and buying guide

Who this product is for

This flashing is designed for builders, roofers, and experienced DIY installers undertaking timber frame roof construction or renovation work. It is specifically suited to projects involving VELUX roof window installation where a combined twin and single flashing solution will simplify the build sequence and reduce material handling on site.

These flashings are compatible with VELUX roofing systems and are rated for pitched roofs only. You must verify that your roof pitch falls within the specified range before purchase and installation.

• Suitable roof pitch: 30° to 60°
• Maximum roof length: 6 m
• Designed for timber frame construction
• Integrate with VELUX window and roofing components

Product size and pack contents

Each flashing unit measures 66 × 118 cm. The EKW FK06 S0312 combines twin and single flashing elements in a single product, eliminating the need to source and fit separate components. Confirm the quantity required for your installation before ordering, based on the number of roof window openings and roof layout complexity.

Pre-installation checks

Before fixing, inspect the flashing for any damage in transit and verify that the timber grade and FSC certification meet your project specifications. Ensure the roof pitch has been accurately measured and falls within the 30–60° range. Check that all VELUX window and roofing system components are compatible with this flashing model, and that the roof structure is sound and ready to receive the flashing. Have all necessary fixings and sealants to hand before starting work.
