FTP-V L3 centre pivot windows are the most popular type of Fakro roof window sold in Europe. The well-designed centre pivot allows the sash to be opened in a range of positions, thus increasing the amount of fresh air that can be drawn into the room. The sash can also be rotated through 180° and locked, allowing easy and safe cleaning of the outer pane to be carried out. Such pivot windows are operated using a two-part hinge. As the air inlet is positioned at the top of the frame, Fakro windows have a 6% greater surface area when compared with similar window sizes from other manufacturers. This increases the availability of light into the room.
