Fixing and buying guide

What this product is and who it is for

This is a standard tile flashing system that creates a weather-tight seal between a VELUX roof window and a tiled roof. It is designed for builders, roofers, and serious DIY installers undertaking new build construction or refurbishment work where a 134×98cm roof window opening is required. The flashing ensures water runs safely off the roof and prevents weather ingress around the window frame.
