Window Security

Fit Window locks on all ground floor windows and upstairs windows that could be accessible from drainpipes and flat roofs. An intruder could otherwise slip a window catch from outside with a knife blade or by breaking the glass to open the catch.

Window locks secure the windows to the frame by a simple bolt or clasp operation. This means that forced entry can only be made by breaking all the glass in the windows. The time taken and the noise made would deter most burglars. It is however disturbing that only a minority of households have window locks fitted.

A casement window (outward opening hinged windows which may also include a fixed pane) should have a window lock fitted on the window frame opposite the hinges and secured into the central style or side of the outer frame.

Sash windows comprise two frames that slide vertically over one another to open. It is recommended that sash bolts are fitted to secure the lower frame to the upper at either end of the mid intersection of the window when it is closed. Window locks can also be fitted on the side of both windows and secured into the main frame.

Sliding windows are similar to sash windows but are configured horizontally. As with sash windows sliding windows can be secured with a locking bolt where the sliding frames overlap when the window is closed or by window locks at convenient points where the window met the outer frames

A number of types of window locks are available. Contact your local stockist for the most appropriate locks for your home.

If you are getting new glass for your windows consider laminated glass. This type of glass is harder to break. As a last resort, you may wish to install security grilles to the windows.

Louvre windows present particular difficulties as the slats can easily be removed from the frames. The slats should be glued in place and a special louvre lock fitted. Consider replacing the windows with fixed glass.

Check that window frames are in good repair. A good lock is wasted if there is a rotten window frame the burglar can easily push in.

Security can be a problem with replacement windows. Internal beading means that the glass is fitted from the inside of the house, so a burglar can not easily remove the beading and the glass in one piece.

But, some externally beaded systems have special security clips and tape that prevents easy removal of the glass. Look for compliance to the BSI PAS 011 specification. If the window doesn't have that then it is best to go for internally beaded windows.

When purchasing replacement windows make sure you purchase the ones with the BSI Kitemark Scheme - Product Approved Specification PAS 011. These offer greater security against the burglar attempting to gain entry.
