Tilt and turn windows
A tilt and turn window does two things: tilt the top inwards for secure background ventilation, or swing the whole sash inwards like a door for cleaning and escape. They open inwards, which makes them the standard choice for flats and anywhere an outward opener would be a hazard.
Tilt and turn is common across Europe and less so in UK housing, but it solves two specific problems better than a casement does: cleaning an upper floor window from inside, and ventilating a room without leaving it insecure.

The two positions, and what each is for
Turn the handle ninety degrees and the sash tilts inward at the top by a few inches. The gap is too small to climb through, so you can leave it open while you are out, and rain largely stays outside.
Turn the handle one hundred and eighty degrees and the whole sash swings inwards on side hinges. That gives full ventilation, a clear escape route, and access to both faces of the glass from inside the room.
Why flats and upper floors favour them
An outward-opening casement above ground level is awkward to clean and, over a balcony or walkway, can be a hazard. An inward-opening sash removes both problems, which is why managing agents often specify tilt and turn for apartment blocks.
The cost is interior space. The sash swings into the room, so curtains, blinds and anything on the sill have to accommodate it.
Cost and hardware
Expect to pay somewhat more than an equivalent casement. The hardware carries the full weight of the sash in two different planes and is correspondingly more substantial, which is also why quality of hardware matters even more here than usual.
Tilt and turn windows: common questions
- Are tilt and turn windows secure in the tilt position?
- The tilt gap is small and the sash remains engaged with the frame, so it is far more secure than a casement left ajar. It is still an opening, so judgement applies on a ground-floor window.
- Do tilt and turn windows take up room inside?
- In the fully open position, yes. The sash swings into the room, so it is worth checking what sits under and beside the window before choosing this style.
- Can tilt and turn windows be a fire escape?
- In the turn position they give a large unobstructed opening, which generally makes them well suited to escape. The specific clear opening dimensions still need checking against the regulations at survey.
