This flashing is made up of lower, upper and side elements, the dimensions of which are dependent on the window height. The side elements of the flashing are laid alternately with the roof covering. The lower element has a plastic mat glued to the underside thus allowing the flashing to adhere to the roof covering for a neat fit. A gutter installed above the window allows condensation todrain away. The EL flashing is ideal for fitting windows within slated roofs coverings up to 10mm (2 x 5mm) thickness. It is applied as standard to individual windows in the slope of the roof.
