5 Key Safety Benefits You Should Know
When it comes to aluminium windows, aesthetics and ventilation are often top priorities. However, safety is just as crucial—especially in residential buildings, high-rise apartments, schools, and hospitals. One small hardware component that plays a big role in safety is the window stay for aluminium windows.

So, what does a window stay for aluminium windows do, and how does it help protect your home or building occupants?
Here are 5 ways a quality window stay for aluminium windows enhances safety:
1. Prevents Accidental Falls – Especially for Children
One of the biggest safety risks with openable aluminium windows is the potential for accidental falls, especially in high-rise buildings. A properly installed window stay for aluminium windows can:
- Limit the opening angle of the sash
- Prevent the window from opening too wide
- Reduce the risk of children leaning out and falling
Many countries even require child-safety window restrictors by law in residential buildings above a certain height.
2. Protects Against Strong Wind Damage
In windy environments, aluminium windows that open outward can slam shut or bend hinges if not properly supported. A heavy-duty window stay for aluminium windows can:
- Act as a wind brace
- Keep the window steady in windy conditions
- Prevent sudden movements that could cause breakage or injury
For coastal areas or buildings above 10 stories, wind-rated window stays are highly recommended.
3. Reduces the Risk of Finger Injuries
Fast-closing or swinging windows can cause painful accidents, especially for children or elderly users. A window stay for aluminium windows helps by:
- Slowing down the closing movement
- Holding the window in a fixed, stable position
- Preventing unintentional slamming
This adds an important layer of passive safety to homes, schools, and healthcare facilities.
4. Improves Security Against Forced Entry
Some window stays come with lockable or friction-hold mechanisms, making it harder for intruders to push the sash open from the outside. These are especially useful in:
- Ground-floor windows
- Balcony windows
- Public-facing buildings
Combined with secure handles and locks, the window stay for aluminium windows can help form a multi-point security system for aluminium windows.
5. Supports Controlled Ventilation Without Compromising Safety
In many buildings, users want fresh air without risking wide-open windows. Window stays for aluminium windows allow:
- A fixed opening angle (e.g. 10cm or 15°)
- Continuous airflow while limiting how far the window opens
- A balance between ventilation and safety—ideal for hospitals, schools, and bedrooms
This is why window stays are often installed in upper-hung, top-hung, and outward-opening casement windows.
