Our timber tilt and turn windows are designed to provide exceptional versatility and performance. Incorporating a high-performance dual hinge system, the window design can open into the room from either the side or the top, making it ideally suited to buildings with external shutters.
Our timber tilt and turn windows can support numerous sizes, including triple-glazed units. Coupled with a variety of paint, stain, and window furniture options, the window can be highly customised to meet precise project requirements. For maximum security, multipoint locking is distributed around the frame, and toughened glass can be specified to meet the demands of Part Q. Dual weather seals, discreetly positioned, provide excellent weather performance.
Period properties can opt for our Traditional timber tilt and turn windows, which have been adapted to remain in keeping with the original aesthetic of the property. Tilt – Rotating the handle by 90 degrees allows the window to tilt open for ventilation purposes. Turn – Rotating the handle by 180 degrees allows the window to turn inwards.
