At first this may seem like a contradiction in terms, but there are many instances where you may want to lock your window in the open position. Most windows are meant to be opened, they provide fresh, clean air and help remove pollutants, allergens and mould spores from your living space.

How can you keep your window locked, but open?

Now that we’ve looked at why you may want to keep your windows locked, but open, let’s talk about how. There are a few products that allow you to keep your windows open, but locked. Most of these are purpose-built for different window styles, such as window stoppers for windows that slide, and window restrictors, which work on casement style windows.

Benefits of keeping your windows open 

We’ve briefly touched on some benefits of keeping your window open, but these can be wide ranging, not just in the present moment, but well into the future. Fresh air is one of the most important needs of the human body, and can lead to better cognitive functioning, better sleep and a better mood. This brings us to the first major benefit of keeping your windows open.


Many homes have inadequate ventilation, this is particularly true in the UK where winter temperatures mean windows are usually shut. But even in these colder months it is essential to allow fresh air into the home to reduce carbon dioxide levels.


Good ventilation is facilitated by currents of air called crosswinds. What you want to do is create a breeze through the home that allows fresh air to replace stale air. Window latches that allow you to keep your window open are a great way to achieve this important natural airflow as all you need to do is open windows on opposite sides of the space you want to ventilate and let the air currents do the rest.


For the parents of young children open windows may pose a very different risk. Instead of worrying about people getting in they worry about their child getting out and injuring themselves in a fall. Window security devices that allow you to keep your window open, but only allow for small openings (like MiniLatch from LockLatch) are a great way to childproof your windows.
