Flashings are an essential part of fitting roof windows with different roofing materials. They are designed to make a secure connection between windows and the roof against any weather conditions (rain, wind or snow). Proper type of the flashing, adjusted to the roofing material, guarantees a tight fitting.
Flashings OKS allow fitting windows in the slate roofing up to 0.8 cm in height.
They are made of sheet aluminium coated with grey polyester. RAL colour 7022
