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.
Universal OKT flashing allows the window to be connected to flat and profiled roofing materials up to 9 cm in profile.
This type of flashing is extremely tight thanks to a longer EPDM rubber lining.
They are made of sheet aluminium coated with grey polyester. RAL colour 7022
