VELUX Twin and Combination Flashings 55x78cm EBW CK02 0021B
What this product is and who it is for
These flashings provide weather-tight sealing where roof penetrations or junctions occur on pitched roofs. They are suitable for timber-framed buildings with either EPB or solid roof construction. The product is designed for both trade professionals and serious DIY installers who need reliable, durable flashing solutions that can handle exposed roof conditions.
Compatibility and sizing
The 55x78cm size accommodates roof lengths up to 8m in a single application. The combination design means one product type can be used across different roof configurations, reducing the need to stock multiple flashing variants. These flashings are graded for timber and suit standard pit installations on pitched roofs.
