Velux Single Tile Flashing is designed to integrate a Velux roof window into the tile roofing material up to 120mm in profile. It ensures that the window is weathertight and stops any leaking. The flashing fits underneath the roofing material with the water being collected in the built-in gutter system. This allows the water to flow smoothly down the side of the window. Suitable for using with roof tiles, interlocking slate, thatch and profiled sheeting and does not come with the installation products.
