A tilt-and-turn window is a window type with a special multi-point hardware that allows two motions: the sash can swing fully open inward like a casement, and it can also tilt inward from the top for ventilation. Originating in Germany, this system has become the European standard for modern PVC and aluminium windows.
How the hardware works
The handle position controls which motion is possible:
- Handle down — window closed and locked
- Handle horizontal — window swings open like a normal casement
- Handle up — window tilts inward at the top, hinged at the bottom
The transition is controlled by an ingenious multi-point locking system with pins, scissor stays and corner drives operating around the perimeter of the sash.
Advantages
- Safe ventilation — in tilt position the opening is limited and hard to force
- Easy cleaning — in swing mode the outside can be cleaned from inside
- Compact — no separate vents needed alongside opening sashes
- Burglar-resistant — modern multi-point locks often meet RC2 standards
Applications
Tilt-and-turn windows are mainly used in:
- Bedrooms — overnight ventilation in tilt mode
- Kitchens — quick air change by swinging the sash open
- Apartments — safe ventilation at height
- Renovation — easy replacement of old casements with much better insulation values
Points to watch
- Heavily loaded mechanism — the hardware bears the full weight of the glazing; maintenance is important
- Not suitable for very large sizes — for very heavy sashes, two separate windows are preferred
- Weather sealing — a good perimeter gasket on the rebate is essential
- Lubrication — lubricate the hinge points and locking pins at least once a year
