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/U 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.
