Which of our ranges actually offers this
Which of our windows actually give you tilt & turn?
Alitherm Heritage, our aluminium range, is confirmed to offer tilt and turn. We haven't confirmed it either way yet on our uPVC range, so we won't claim it until we have. Our Cortizo aluminium casement range doesn't offer it at all, it's outward-opening only, by design. Most local installers write as if tilt and turn is available across their whole catalogue. We'd rather tell you exactly where you stand.
- Alitherm Heritage aluminium: confirmed
- uPVC (Rehau Total 70): not currently confirmed either way
- Cortizo aluminium casement: doesn't offer it, outward-opening only

One handle, two ways to open
If you haven't lived with one before, here's what it actually does.
One single handle runs the whole lock. Turn it one way and you get tilt. Turn it further and you get turn. You can't jump straight from closed to fully open, the handle makes you pass through tilt first.
Tilt
The top of the sash pulls inward a fixed amount. The bottom stays locked in place.
For secure ventilation, even when you're out.
Turn
The bottom unlocks and the whole sash swings inward on its side hinges.
For full ventilation, and cleaning both sides of the glass from inside.
Tilt and turn hardware was designed in Germany in the 1950s and became the standard across most of mainland Europe. Britain stuck with casement and sash windows instead, which is why it can still feel unfamiliar here.
The practical case
Why tilt & turn suits upper floors and flats
Because the turn position swings the whole sash inward, you can clean both sides of the glass from inside the room. That's specifically useful on an upper floor or in a flat, where cleaning the outside of a standard window otherwise means a ladder, a pole, or a window cleaner. Day to day, the tilt position gives you secure ventilation without opening the window fully.
- Clean both faces from inside, no ladder
- Secure ventilation via the tilt position
- Especially useful for upper floors and flats

Security & child safety
Is it secure, and safe for a child's bedroom?
Tilt and turn windows lock at multiple points around the frame, not just at the handle. Alitherm Heritage is security-tested to PAS24:2016, though the manufacturer's own published scope covers casement windows and fixed lights only, so we won't claim that result for tilt & turn specifically until it's confirmed. If the window is a bedroom's only escape route, Building Regulations require any restrictor to release from inside without a key or tool, for an instant emergency exit. That's a different, quicker-release device from the tamper-resistant restrictor used purely to stop a young child falling, on a window that isn't an escape route. Fitting the wrong one creates either a fall risk or an escape risk, the two aren't automatically compatible on the same hardware. You won't find this explained plainly anywhere else in the market, and we won't gloss over it either.

Natasha Evans
Josh and his team worked incredibly hard replacing all of the windows and doors in our house, including fitting a beautiful bifold door in place of our old French doors. We could not be happier with the results. The quality of the workmanship was excellent, and Josh was fantastic with communication throughout the whole process. He was reliable, professional, and kept us updated every step of the way. We would highly recommend him to anyone looking for high-quality work and great service.
Andy
Josh installed our new windows, triple track doors, roof lights and front door at our house in Bournemouth. A very professional, tidy and efficient service from beginning to end. Would highly recommend Wilshaw Glazing.
How much do tilt & turn windows cost?
We don't publish a fixed price, because it depends on the size, number of windows and finish. The fastest way to get a real number is a free survey.
Are tilt & turn windows a good idea? What are the disadvantages?
They're a genuinely useful style, especially upstairs or in a flat, but the mechanism costs more than a standard casement hinge and takes up a little more depth in the frame. For most ground-floor rooms, a standard casement does the job for less.
What's the difference between a tilt & turn window and a standard casement?
A casement swings open on a side hinge. A tilt & turn window does two things from one handle: tilts inward at the top for ventilation, or swings fully inward on side hinges for cleaning and full opening.
Is a tilt & turn window secure enough for a ground-floor room?
Yes, with multi-point locking around the frame. We'll talk you through the security spec and the PAS24 testing scope at survey.
Can tilt and turn windows be repaired?
Often, yes. Have a look at our repairs page, or send us a photo and we'll give you an honest answer.
Can I have a tilt & turn window in a colour to match the rest of my house?
Alitherm Heritage comes in a wide range of finishes. Our aluminium windows page has the full colour range.
