Comparison
Sash vs tilt and turn windows: which should you choose?
Short answer
Choose a sash look when the appearance of a period front elevation matters most, and choose tilt and turn when you want the easiest cleaning, secure ventilation and a wide opening, especially upstairs or in flats. Sash windows slide vertically and suit traditional houses; tilt and turn windows open inwards, either tilted at the top or swung fully open like a door.
How each window opens
A traditional sash window has two panels that slide up and down past each other inside the frame. You can open the top, the bottom or both, which creates a natural flow of air with warm air leaving at the top and cooler air coming in at the bottom. The panels never project into the room or out over the path.
A tilt and turn window has one handle with two positions. In tilt mode the top of the sash leans into the room a little, giving ventilation that is hard to reach from outside. In turn mode the whole sash swings inwards on side hinges, leaving the opening almost completely clear. This is the style we fit in uPVC across Leicester and the surrounding area.
Side by side
The main differences at a glance:
| Opening | Sash: slides vertically. Tilt and turn: tilts inward at the top or swings in fully. |
|---|---|
| Look | Sash: traditional, suits Victorian and Edwardian fronts. Tilt and turn: clean and modern. |
| Cleaning | Sash: depends on the design. Tilt and turn: both sides of the glass cleaned from inside. |
| Ventilation | Sash: top and bottom airflow. Tilt and turn: secure tilt for background air. |
| Clear opening | Sash: at most about half the frame. Tilt and turn: close to the whole frame. |
| Furniture | Sash: nothing opens into the room. Tilt and turn: keep the sill clear to open fully. |
Where tilt and turn wins
Tilt and turn windows are hard to beat on upper floors. Because the sash turns fully inward you can clean the outside of the glass from inside the room, with no ladder. The large opening also makes them a strong choice for a bedroom window that needs to work as an escape route, which is something we check at survey. In tilt mode you can leave the window open overnight or in light rain for fresh air while it stays locked in position.
They also seal well. The sash presses against the frame on all four sides when closed, which helps with draughts and noise from a busy road.
Where the sash look wins
On a period front elevation, especially in a street where neighbouring houses still have sash windows, the vertical sliding look is often what keeps the house looking right. In a conservation area the council may expect replacements on the street side to match the original style, and a modern inward opening window may not be acceptable there. It is always worth checking with the conservation officer before ordering anything.
Sash windows also suit rooms where something sits right in front of the window, such as a kitchen sink or a desk, because nothing opens into the room.
A common mix
Many homeowners do not pick one style for the whole house. Keeping a traditional look on the street facing side and using tilt and turn on the back elevation, in loft rooms or in upstairs bedrooms gives the character where people see it and the practicality where you live.
