FAKRO FTT U8 Thermo is wooden roof window with quadruple glazing, dedicated to passive houses. Together with Thermo flashing and insulation set gives one of the best U-values on the market and creates super-insulated roof-window-set.

FAKRO FTT U8 window with innovative structure, characterized by superb thermal performance and air-tightness is suitable for air-conditioned rooms with mechanical ventilation systems as well as passive buildings. It offers very good overall heat-transfer coefficient for the whole window, guaranteeing significant energy savings. The glazing unit is set in a specially designed sash frame, which offers wider wooden profiles in comparison with standard windows. The window is equipped with five seals. Such structure minimises thermal bridging and provides improved window insulation. The sash is opened like a pivot window, however axis of rotation of the sash has been raised by 7cm in relation to its geometric centre. Thanks to it, even a tall person can comfortably stand upright by the open roof window. The opened sash can be stopped anywhere between 0° and 40°, because it is supported by an innovatory assisting mechanism. The mechanism balances the forces resulting from the length differences between the upper and lower section of the sash. Large sizes and innovative structural solutions applied in FTT roof windows, ensure high comfort of use of the loft space as well as unobstructed access to the open window.

Benfits of FAKRO FTT U8 Thermo

Installing large, highly energy-efficient FTT windows brings many advantages. The sizeable glazed area ensures effective lighting of the loft and spacial structure applied insulates the interior, thus protecting the room from cooling. The FTT window allows energy from the sun to be harnessed as the solar radiation can pass through the glazing, even in the winter on sunny days, to provide a radient heating effect in the room. The heat is trapped inside the room as glass with low emission coating prevents it from escaping. For this reason, in the winter, rooms in the loft are partially heated in a natural way.

  • The sash frame is thicker in comparison with a standard window, manufactured in pine, vacuum impregnated and double coated with ecological acrylic lacquer;
  • Tripple-chamber passive glazing unit; consists of four panes of glass. The whole unit incorporates three layers of low-emission coating and warm TGI spacers. Three inter-pane voids are filled with inert gas – krypton. Such structured glazing units provide superb thermal performance Ug=0.3 W/m²K.
  • Sold as a set with the Thermo flashing and XDK set
  • Glazing seal provides additional tightness in extreme weather conditions and reduces the micro pulses of the cladding profiles during heavy rain;
