VELUX Window Flashings are essential for the installation of your roof window and come in a variety of different materials and sizes to suit your window. Based on your roofing material you are able to select the flashing that is best suited to you. The different types of materials are as follows:� Tiles up to 120mm in profile, min roof pitch 15� Plain tiles up to 15mm thick, 300mm long,�min roof pitch 25� Slate up to 8mm thick,�min roof pitch 15� If you are not sure about your roof pitch why not download the VELUX Roof Pitch App from the�Appstore�or�Google Play. If you don't have one of the above roofing materials please contact us. The flashing is the only essential component to install your window as it makes it weather proof. However, we offer the option of inlcuding a BDX 2000 insulation and underefelt collar. Although this isn't essential it's nice to have as the insuation collar helps reduce heat loss and the underfelt collar ensures a weather tight seal and includes a transverse gutter which leads water away from the head of the roof window if a tile or slate is broken above the window.
