Window Security

Many people when approaching home security can make the mistake of concentrating solely on door security totally neglecting window security.

We understand why as year on year statistically, 75% of all burglaries are via the door.

This does however still leave a 25% chance of a burglar targeting your windows for entry into your home and in certain areas of the country this percentage will of course be higher.

There are two methods of entry for forcing entry via a locked window and Sheffield Locksmiths SheffLOCK advise you to have the following installed to significantly boost your window defences against attack:

Window levering

This is where a burglar uses an implement such as a flat bladed screwdriver or crowbar.

The target areas is the keeps where the bolts engage into when your window is closed then locked.

Once these keeps are broken or the window frame is levered to allow the bolts to pop out of the keeps, the window is opened easily, effectively bypassing all of the window security.

SheffLOCK advise you to internally install lockable Sash jammers that provide excellent reinforcement of your windows should any such attempt be made.

We are not going to disclose exactly how easy it is for a burglar to “pop” and smash toughened (also known as tempered glass) double glazed glass panels.

This method is seen time and time again via CCTV released from victims and the police when such a burglary method is used.

The majority of households at best will have a toughened inner and outer pane of glass installed in any double glazed glass unit.

When hit, the glass does not provide an adequate defence against attack and simply shatters into smaller pieces as it is designed to not cause injuries if broken.

Sheffield locksmiths SheffLOCK echo the advice of the police who advise to have laminate glass installed or at the very least have accredited adhesive window film installed.

Laminated Glass

Laminated glass has the same strength as ordinary glass but it consists of two pieces of glass containing a sandwich of plastic interlayer. If the glass does get broken this interlayer holds the whole piece in place so there is no hole left in the window for an intruder to get in through for example or large free shards that can cut. It is the same glass you find in car windscreens and shop fronts.

Toughened Glass
Toughened Glass

Toughened glass is upto five times as strong as ordinary glass which means that it has to be hit much harder in order to break, also when it does break it is into lots of small pieces which are much less dangerous. It’s the same glass that you will find in bus stops and phone boxes where you may have seen it smashed into small pieces on the floor.

Standard Annealed Glass
Standard Annealed Glass

This is used in every other window where safety glazing is not required & when broken breaks into jagged pieces. Burglars would almost never try & gain entry through this type of glazing so there’s no need to change this type.
