Fakro FTT U8 Pine Quadruple Glazed Centre Pivot Roof Window

Fakro FTT U8 Pine Quadruple Glazed Centre Pivot Roof Window

The Fakro FTT U8 Pine Quadruple Glazed Centre Pivot Roof Window combines exceptional design, high performance and robust safety features, making it the ideal choice for bringing natural light and ventilation into your home. Crafted from a natural wood frame with a timeless, durable finish, it's coated internally with two layers of clear lacquer for a polished, long-lasting look, while a stylish RAL7022 aluminium exterior ensures a modern, weather-resistant finish outside.

Passive House Performance

This window is Passive House certified, with five secure seals and a quadruple glazing unit delivering an ultra-low U-value of 0.58W/m²K. The glazing construction (4H-12-4HT-12-4HT-12-4HT) is specifically approved for Passive House standards, offering outstanding energy efficiency alongside an acoustic rating of 36dB (-2,-5) to help minimise external noise for a genuinely quieter indoor environment.

What's Included

The kit includes thermo flashing along with a set of insulating collars: the XDP breather membrane collar, which links the window to the roof system and provides insulation around it, and the XDS air-tight flashing, used internally to form a barrier against warm, humid air between the internal reveal of the window and the plasterboard.

Security and Ventilation

Safety and security are built in as standard thanks to the topSafe system, which combines reinforced hinges, a secure keep and a steel slat to the lower sash, achieving at least Class III safety under EN13049 standards. The ergonomically designed handle at the bottom offers two micro-opening positions, giving you added convenience for everyday ventilation.

Build Quality and Certification

Suitable for roof pitches ranging from 15° to 70°, this window is FSC certified, using responsibly sourced timber for genuine sustainability, and BBA approved under certificate 02/3944 for guaranteed quality and reliability. It comes backed by a 10-year warranty on the window, a 20-year warranty on the glazing unit, and a lifetime warranty against hail damage.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
