All About Window Security

Windows, while offering natural light and ventilation, can also be vulnerable points for intruders if not adequately secured. Window security is often overlooked, but windows are a common point of entry for burglars, so making sure they are secure is vitally important. And with a variety of window locks and security devices on the market there is no excuse not to secure these potential entry points.

This article will highlight the main types of window locks and associated mechanisms as well as discussing some security tips around windows.

Types of Window Locks:

There are several types of window locks available. These include:

Keyed locks. These require a key to secure and unlock various types of window.
Sash locks. Designed for sliding sash windows.
Sliding window locks.
Casement locks. For casement windows. They secure the handle against the frame.

As you can probably tell, different windows require different types of window locks.

So selecting the right window lock firstly depends on the type of window you have.

Often the lock is dependent on the opening mechanism of the window you are fitting it to.

Wooden Sash Windows

These often open by lifting the bottom window towards the top window. Sash windows should always be secured with bolts that screw into the opposite window. This means that neither the bottom window can be moved up, and the top window cannot be forced down either.

uPVC Windows

Usually these will have three main components. The window itself, the locking mechanism that sits inside the window along the frame, and the locking handle.

Wooden/Metal windows - Casement

Normally found on older properties. Casement windows are often held open using a casement stay, they are also locked with this casement stay.

The casement stay is normally a length of metal bar at the bottom of the window with multiple holes along the length of it, these holes are used with a pin to hold the window open or closed. It is advisable to install locking casement stays or bolts that go into the frame and stop the window from opening without a key.

Types of window opening mechanisms:

Along with the different types of window come different opening mechanisms. These include:

Lockable window handles
Restrictor stays. Prevent the window from opening fully and thus preventing easy access to intruders
Ventilation locks. Designed to keep windows slightly open for ventilation while maintaining security, these locks prevent the window from being opened further.

Of the window handles available, the following come with lockable versions:

Cockspur handles (the latching part overlaps the frame to secure the window in the closed position).
uPVC Espagnolette handles (e.g. inline or offset / spindle or Cadenza operated)
Tilt & turn handles (normally on modern style metal windows)

If you’re looking to enhance your window security here are some things to consider:

Prioritise ground floor windows
Avoid single glazed windows and always try to opt for reinforced glass
Often commercial properties fit security bars as an additional barrier to entry – that can also be an option for the home too.

Having secure window locks can also prevent accidents, especially if you have young mischievous children in your home. Having a lockable window will prevent them from opening the window and endangering themselves.
