This is a double glazed window with laminated glazing and has a uValue of 1.3. FT centre pivot windows are the most popular type of FAKRO roof window. The well-designed centre pivot allows the sash to be opened in a range of positions, thus increasing the amount of fresh air which 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 sized windows made by other manufacturers. As a result they maximise the amount of natural light in a room. Properties Window uValue: 1.3 W/m2K. Glazing uValue: 1.1 W/m2K. Acoustic insulation Rw: 35dB. Inert gas filled panes: argon.
