75 Series Tilt & Turn Windows

The 75 Series tilt and turn window is engineered around the European dual-action handle — tilt the sash inwards for draught-free ventilation, or turn it fully open for cleaning and maximum airflow. The 75mm frame depth, 1.8mm aluminium wall and 30mm multi-chamber thermal break work together to keep Uf between 1.4 and 1.8 W/(m²·K) without sacrificing the slim 28mm frame sightline. Siegenia concealed hardware and HOPPE handles come as standard, paired with AkzoNobel powder coating and EPDM co-extruded seals across a three-seal perimeter. Whether used in a single residential opening or stacked across a multi-storey façade, the 75 Series combines passive-house comfort with a clean, modern aesthetic.
