The way a window opens affects everyday comfort, use of space, ventilation and safety.
When choosing windows, attention often goes to the frame material and glazing, but the opening type is just as important in practical terms. Here are the most common solutions and where each works best.
Best suited to:
The sash opens inwards along one side, much like a door, providing a fully open ventilation area.
Rooms that need intensive ventilation and full access for cleaning the outside of the glass from indoors.
The most common solution in modern homes, combining full inward opening with a top-tilt position for controlled ventilation.
Almost any room, particularly homes with small children or pets where restricted ventilation is useful.
A window that does not open and is intended solely to provide daylight and a view.
Large glazed areas where other windows provide ventilation, or high positions that would be difficult to reach.
The sash opens by sliding horizontally or vertically rather than swinging into the room.
Spaces where an inward-opening sash could interfere with furniture or use of a terrace.
Bedrooms and children's rooms often benefit from tilt-and-turn windows. In kitchens and bathrooms, the layout and required ventilation intensity guide the choice.
Side-hung and tilt-and-turn windows make it easy to clean the outside of the glass from indoors, which matters especially on upper floors.
A tilt position provides ventilation without leaving the sash fully open, although suitable restrictors should still be considered for child safety.
An inward-opening sash needs clear space, so windowsills and furniture positions should be considered during planning.
Yes — and this is often the best approach. Bedrooms might use tilt-and-turn windows, while a large living room overlooking the garden could combine fixed glazing with a smaller opening section at the side.
