Fakro FTT/U U6 Centre-pivot pine roof window

To combine maximum brightness and thermal comfort, FAKRO FTT/U U6 roof windows are specifically designed for energy-efficient buildings.‎ The roof windows provide plenty of natural light without compromising thermal insulation, while offering wide views of the surrounding landscape.‎ The high functionality and minimalist design of the FTT/U U6 perfectly match the image of any interior space.‎ FTT is a roof window with a tilt and turn opening, specially developed for energy-efficient construction and passive houses.‎ This window features a casement shaped for the insertion of double-glazing so that, compared to a standard window, the frame cross-section is enlarged, which benefits the minimisation of thermal bridges and the containment of heat loss.‎ The special construction of the window also features as many as five sealing gaskets, further reducing heat loss.‎ In the penthouse of the Heuvelrijk Berg en Dal, the FTT models are equipped with U6 triple-glazing, which enables this window to achieve excellent thermal transmittance performance: Uw = 0.‎80 W/m2K, when installed with standard fitting; Uw = 0.‎71 W/m2K, when installed with EHN-AT Thermo fitting.‎ Installable on pitches with an inclination from 15° to 70°, the FTT frame is made of the highest quality pine wood, glued in layers and vacuum-impregnated, finished with three coats of ecological transparent acrylic varnish.‎
