Installing new windows on your property or bolstering what’s already there? Great idea! Upgrading your window locks is a simple and tangible way to improve home security and deter intruders – and a simple Google search will show that there are thousands of options out there. In order to help you make an informed decision and cut through the noise, here is a rundown of 6 of the most secure window locks to prevent intrusion.
But first, let’s get some of the prior considerations out of the way… starting with the importance of window lock maintenance and finding out which types are compatible with your home.
Why Are Window Locks Important?
Many underestimate the potency that a strong window lock can bring to a home’s overall security. Did you know that 30% of domestic burglaries involving breaking and entering began with entry via a window? That’s reason enough to ensure that yours are well looked after.
You might think, “What’s stopping them from simply shattering the glass?” Well, smashing their way in may alert neighbours or passersby to the crime. Intruders are more likely to take the path of least resistance, in other words, finding easy, hidden points of access that haven’t been properly secured.
With this in mind, it’s imperative that you replace the lock when:
- The key doesn’t fully turn or gets stuck in the lock.
- The key turns in the lock but fails to open it.
- The mechanism becomes unwieldy and stiff.
If you are a landlord, securing your rental property is a core responsibility to ensure that your tenants and assets remain safe and sound. You may also want to update your window locking systems if you have bought a new house for added peace of mind and to fulfil your insurance obligations. Either way, you should ensure that they meet BS3621 standard at the very least.
Understanding Window Lock Compatibility
Just like there are many types of door locksets that are more or less suitable for different types of doors, it’s worth noting that some types of locks are only compatible with specific windows. Here is a quick explainer.
If you’re already clued up about which locks are compatible for you, skip to our list of the top 6 most secure windows.
Picture Windows
Picture windows offer expansive views and are typically fixed, meaning they cannot be opened. While they don’t require traditional locks, installing security film or window bars can enhance their resistance to forced entry.
Casement Windows
Casement windows are hinged on one side and swing outward, often operated with a crank handle. Compatible locks include:
Keyed locks – These locks feature a key-operated mechanism installed on the window frame, offering a secure closure when the window is shut.
Latches – Casement windows may come with integrated latches that securely fasten the window sash to the frame when closed.
Bay Windows
Bay windows protrude outward from the exterior wall, typically featuring a combination of fixed and operable window panels. Lock options for bay windows include:
Keyed locks – Install keyed locks on the operable sections of the bay window to prevent unauthorized access.
Pin locks – Pin locks can be fitted on both fixed and operable panels.
Single-Hung Windows
Single-hung windows consist of two sashes, with only the bottom sash movable while the top remains fixed. Compatible locks include:
Keyed locks – Secure the bottom sash with keyed locks to prevent intruders from lifting it open.
Latches – Install latches on the meeting rail to hold the bottom sash firmly in place when closed.
Double-Hung Windows
Double-hung windows feature two vertically sliding sashes that can be opened independently. Suitable locks for double-hung windows include:
Keyed locks – Install keyed locks on both the upper and lower sashes to secure them in the closed position.
Sliding locks – Attach sliding locks to the meeting rails of the window to prevent the sashes from being raised or lowered.
Awning Windows
Awning windows are hinged at the top and open outward from the bottom. Compatible locks for awning windows include:
Keyed locks – Use keyed locks to secure the window at the bottom when closed, preventing it from being pushed open from the outside.
Folding locks – Install folding locks on the sides of the window frame to provide additional reinforcement.
Horizontal Sliding Windows
Horizontal sliding windows feature sashes that slide horizontally along tracks. Suitable locks for these windows include:
Sliding locks – Attach sliding locks to the meeting rails to prevent the sashes from being forced open.
Window wedges – Place window wedges along the bottom track to prevent the window from being lifted out of its frame.
