The FTT roof window features an innovative structure which offers excellent thermal insulation parameters with an impressive Uw of 0.58W/m²K and is the most energy-efficient quadruple glazed window manufactured by FAKRO. These windows comply with the strict Passive House certification criteria and have received an official ‘ph B Certified Component’ accreditation from Passive House.
High energy-efficiency
A triple chamber glazing unit ‘U8’ with Ug = 0.3W/m²K is set in a specially designed sash frame, which offers wider wooden profiles in comparison with standard roof windows.
This window is equipped with five airtight seals and having such a sustainable structure minimalises thermal bridging and provides an improved window insulation.
When placing an order for an FTT U8 Thermo window it is supplied as a complete kit. Flashings are a necessity and within the kit an EHV-AT Thermo is provided to enable installation to be above the roof surface. On the inside of the flashing a flexible insulating material is glued to the inside of the flashing which adheres tightly to the window frame.
Another addition to the all-inclusive package is an XDK insulation flashing kit, which enables fast and efficient installation for thermal insulation, air permeable membranes and air tight membranes around the window.
