Tilt and turn windows are perfect for commercial projects or residential property contracts needing larger or more functional windows.

Our PVC tilt and turn windows offer simple operation with enhanced functionality, safety and security and are suitable for replacement window projects or new build openings. With slim sightlines and integrated multi-functional hardware, they are the ideal trade window with a modern appearance, high security and excellent weather performance.

A rotating window handle turns in one direction, tilting the vent back for ventilation. Rotate the handle the other way, and the entire sash opens in for full ventilation. As a result, these windows are ideal for high-level windows in flats and social housing.

  • U-value of 1.4–0.96 W/m²K
