Security Features on Replacement Windows

Locking Systems:  The standard locks on most replacement windows and doors are espagnolette multi-point locks (including night vent position) on windows and a five point lock for doors.

Most companies will also offer additional options such as:

	Shoot-bolt locks - combined with espagnolette locks - these locks give locking on three sides of opening
	SAC bolt locking - when combined with espagnolette and shoot bolt locks SAC bolts give you locking points / secure points on all four sides of opening
	Entry guard - a sort of "advanced" security chain - this feature allows you to partially open a door in order to confirm the identity of a caller
	Hook and shoot locks - most often fitted to single doors this lock features special shoot bolts at both top and bottom of door sash plus "hook" or "claw" locks on the side

Ask your supplier for further information or specify on your quotation request that you would like to be quoted for some of the above products. 

Special Note - some suppliers will supply locks to a lesser standard than specified here. Others, however, may include better locks as standard.

You must specify your "unique" requirements to all potential suppliers and most importantly - when comparing quotations - compare "like with like". 

Additionally there are many other "comparable" locking systems. Security is one of the most important issues when purchasing replacement windows and doors. It is worth paying particular attention to - especially when there are so many different alternatives.

In the UK there are various British Standards for locks - it's worth asking your supplier if they can conform to these. You may find your insurance company will charge reduced fees if you use better quality locks.

Our top recommendation for locking on PVCu windows would be to combine SAC bolt locking with espagnolette and shoot bolts for maximum security.

Glazing Methods

With PVCU windows in particular you will often hear a lot of "arguments" in favour of using an internally beaded window - instead of an externally beaded window.

Clearly, if the beads holding the glass are on the inside of the window it will be more difficult for a burglar to remove the glass and enter your home. You will often find "sales people" making quite a fuss over this issue and whilst it is relevant to realize that the types of locks used are perhaps more important. Also if a PVCu frame is fully reinforced it will be less likely to "spring open" if attacked with a jemmy/crowbar. 

To Simplify: it's not much use having internal beading if the window "falls down" on some other areas.

Special Note:

Some suppliers of externally beaded windows will fit special glazing gaskets and double-sided tape to the frame and sealed unit in order to improve on the security. Some will even claim security "as good as" internal beading.

Finally:

Whilst not a particular security issue - always ask your supplier if their windows have any special "easy escape" or "fire escape" features. Special hinges can be fitted to help with this - but these are not usually standard items and will add to the cost.
