The Different Types of Window Locks

Window security locks help to keep your home safe from intruders - but not all of them are created equal. In this article, we’ll look at different types of window-locking mechanisms ranging from the least to the most secure. You’ll discover how to evaluate window locks based on the level of protection they offer and learn how to recognise secure window locks you can trust. 

Window Latches

The simple window latch holds windows closed but doesn’t lock them. Although ordinary window latches are convenient, they don’t offer much security. Burglars need only drill a hole under the latch. Then, they use a piece of wire to jiggle it open. 

Sash Locks

Although the name sounds promising, standard sash locks are not particularly secure. A little brute force is often all that’s needed to get the window open. Failing this, intruders can use very simple tools to get around the lock. 

Sliding Bolts

Taking window security locks up a notch, a sliding bolt, though rarely seen, is a small improvement. Nevertheless, it is vulnerable to break-ins. While the bolt itself is reasonably strong, its attachments are often the weak point. The window can be forced. Again, simple tools can overcome the bolt without any need for breaking the window. 

Window Pin Locks

A window pin lock is very similar to a door security chain. The pin prevents the window from being fully opened. Once again, this is a lock with a single attachment point on the window frame, making it easy to break open. It can also be jiggled free with the help of basic hand tools or a bit of wire. 

Window Wedges

The primary function of window wedges is to get a good seal when the window is closed. They’re commonly found on double-glazed windows. Although they are not primarily for security, they can make it a little more difficult for intruders trying to break in. All the same, they can be forced, even when they are made out of brass. 

Keyed Sash Locks

This style of sash window lock requires a key to open it. However, the strength of a sash lock depends on the number of locking points and the sturdiness of the window frame. Although this type of sash window can’t as easily be opened by working directly on the mechanism, a sash lock with a single locking point can be forced. 

Latch Locks With an Integral Key

An improvement on regular latch locks, keyed window latch locks can be relatively sturdy. How well they stand up to attempts to bypass them depends on the number of locking points in the latch, the sturdiness of the latch’s construction, and most importantly, the strength of the window frame. 

Multipoint Window Locks

Multipoint window locks secure the window with several levers. If force is exerted, the energy is spread over several points, making these locks harder to force. Quite often, the strength of the window frame will have a role in security. For example, this is among the types of uPVC window locks. 

Other Locking Systems

By now, you are beginning to see a pattern. There are many types of window locks - even electronic ones - but their security depends on several factors. The number of points a window lock attaches, the locking mechanism, and the strength of the materials to which lock components are attached are all important in determining how secure your window locks are. 

Window Lock Grades

Leaving the rest of the window assembly out of the debate, high-quality locks can help to keep burglars at bay. Window lock grades help you to see what your window lock will withstand. A thief-resistant lock will carry a BS3621 rating. To qualify for this mark of approval, the lock is assessed by the British Standards Institute.

Depending on your insurance policy, your insurer may require you to have BS3621-certified locks on your home’s windows.  

Things to Consider When Upgrading Window Security

Window locks are important elements in your window security, but to ensure you have thief-resistant windows, you must look beyond the lock. 

Window glass is an important consideration. Although burglars prefer not to make a noise when breaking and entering, a single impact may not draw attention. On the other hand, if several blows are required to breach the glass, they are less likely to make the attempt. 

The window frame should also be sturdy. If it can easily splinter or crack, intruders can lever windows open using simple tools. Steel reinforcement offers the best protection. 

Last but not least, you do not want security measures to have a negative effect on your home’s aesthetics. For example, although burglar bars can be very effective in deterring thieves, they may leave you feeling penned in and will affect the view through your windows.
