FAKRO FTT U6 triple-glazed roof windows have been used in combination with in-roof solar thermal panels of the same size in a self-build within Bath’s Central Conservation Area. Head of Sustainable Design at Architects Stride Treglown, Rob Delius installed 6 FAKRO roof windows and 6 FAKRO solar thermal panels using B12/1 horizontal combination flashings on the south aspect. Airtightness was key to the highly sustainable design and with an installed U-value of 0.81W/m2K the FAKRO FTT U6 performance surpasses Passivhaus requirements.
The building, which utilises passive stack ventilation, also has a rainwater harvesting system, green roof area, PV tiles and sheepswool insulation.
