The Passivhaus-approved FTT U8 Thermo features a quadruple-glazed sash with five seals and innovative hinge and lock reinforcement
The Fakro FTT U8 Thermo is the most thermally efficient roof window on the UK market with a single glazing unit. It has an installed U-value of 0.58w/m2k with glazing unit value of 0.3w/m2k.
PassivHaus Certification has been achieved thanks to its quadruple glazing and system of five seals that gives excellent airtightness and minimal risk of thermal bridging. Supplied complete with the EHV-AT Thermo insulated flashing kit, which includes further insulation and an airtight collar, the window provides a complete solution for PassivHaus and EnerPHit projects.
Enhanced security is provided by the patented Fakro TopSafe system, which utilises specially designed hinges and a two-point locking system to secure the sash on both sides of the frame.
When open, the raised pivot point of the sash and balanced hinge mechanism enable the window to be opened at any point up to 40 degrees, giving more headroom to allow even a tall person to stand comfortably by an open window.
