Are Tilt and Turn Windows Secure? Features Every Homeowner Should Look For
Tilt and turn windows are popular for their flexibility, but because they open in two ways, many homeowners ask about tilt and turn window security. The reassuring answer is that a well-designed, well-made tilt and turn window can offer an exceptionally high level of security.
Here our team explains why, and which features to look for when you compare options.
How tilt and turn windows open
Turn the handle to the tilt position and the top of the sash opens inwards, held by a restrictor that leaves a small, controlled gap for fresh air. Turn it to the open position and the whole sash swings into the room like a door.
That second mode lets you clean the outside glass from indoors and gives more airflow on warm days. Both modes rely on precise hardware, which is why build quality matters so much for security. Our guide to tilt and turn windows energy efficiency covers the glazing side of the story.
Tilt and turn window security: the features that matter
Multi-point locking
Rather than relying on one lock near the handle, a good tilt and turn sash engages at multiple points around its perimeter. That secures the window more evenly and makes it much harder for an opportunistic intruder to lever the frame. It also clamps the sash tightly against its seals, which helps keep out draughts and rain.
Strong hinges and hardware
The hinges carry the full weight of the sash in both modes. Low-grade materials can drift out of alignment over time, which affects how the window operates and, ultimately, how securely it locks. Aluminium frames are strong yet lightweight, so they support large panes without the sash dropping.
Lockable handles
A well-engineered handle moves smoothly between positions. A key-lockable handle adds another layer of reassurance on ground-floor or easily reached windows, and in family homes where child safety is a concern.
Security glazing
Toughened or laminated glass may be appropriate depending on the window's location and risk. Laminated glass can help hold together if it is damaged, which makes it harder to create a quick opening.
Are tilt and turn windows secure for families?
For many families, they are a very practical choice. In tilt mode you get controlled ventilation without an opening wide enough for a person to fit through, so a bedroom can be aired overnight with more peace of mind.
The inward-opening turn function also means nobody needs to lean out of an upstairs window to clean the glass. Combined with lockable handles, that makes them well suited to upper floors.
Your checklist for secure windows in the UK
When comparing quotes, ask whether the windows include:
PAS 24 certification.
Secured by Design accreditation.
Several locking points around the sash.
Hinge guards and hard-wearing hinges.
Crimped frame corners.
Lockable handles.
A durable frame material such as aluminium.
It is also worth asking your installer how the windows are fixed into the opening, and whether they will adjust the hardware at handover so every locking point engages cleanly.
Keeping your windows secure over time
Security is not a one-off feature; it depends on the window staying in good order. A few simple habits help:
Lock, do not just close. Turn the handle fully to the locked position every time.
Keep hardware clean. Wipe the locking points and keep the tracks free of grit.
Watch for stiffness. If a handle becomes hard to turn, it may be a sign the sash needs adjusting.
Never force it. Forcing a stuck handle or sash can damage the mechanism, so contact your installer instead.

Frequently asked questions
Are tilt and turn windows secure?
Yes, when they are well designed and well made. Look for multi-point locking, strong hinges, lockable handles and recognised accreditations such as PAS 24 and Secured by Design.
Is aluminium more secure than uPVC for tilt and turn windows?
Security is not determined by material alone, and a well-made uPVC system can be secure. The advantage of aluminium is its strength, which helps keep the sash aligned so the locks keep engaging properly over the long term.
Can you leave tilt and turn windows open at night?
In tilt mode the restrictor leaves only a small gap for ventilation, which is why many people use it in bedrooms. For ground-floor or easily reached windows, we would still suggest closing and locking them when the house is empty.
