reached by climbing onto the roof of your garage or by using a ladder
carelessly left in a neighbor’s garden?
Do they have poor locks, or
flimsy catches, would they be improved by fitting window security locks?

Window Security Locks for All Types of Window.
The central catches that are found on older wooden sash windows
are not in any way secure. Locking versions of these catches, often
described as sash window security locks, are available.
It is recommended that these are fitted in pairs.
Better yet, are sash stops. These are robust, easy to use and can be positioned so the window can be left open a few inches for ventilation.
A steel bolt, secured by a key, is engaged through the inner and
outer frames, and prevents the window from passing the stop. A stop
should be fitted each side of the window.
Tilting and sliding type slash windows are best fitted with both central locking catches and sash stops.
Louver (Louvre) windows were once thought to be quite stylish.
However, it was soon realized just how vulnerable these windows are, the
slats of glass can be slid out in seconds.

supplied with multiple point locking systems fitted as standard. If your
sliding windows are fitted with latches consider fitting sash stops for

the slider to the frame. Ensure that the windows cannot be lifted out
of the frame.
Awning windows are similar to casement windows except they swing
upwards instead of outwards. Many are fitted with winders to ease
opening and closing.
Some awning winders are locking, if they are not,
or for additional security, awning window locks can be fitted
to aluminum and timber frame windows.
Always remove keys from window locks and keep the keys in a place where you can easily get them in an emergency, but out of sight of the window.
Always ensure that your windows are locked before you leave your home.

fit. Make life difficult for the intruder and give yourself peace of
