UPVC & Double Glazing Locksmith in Newcastle

If you live in a modern building, the chances are that you will have double glazing, a fitting which helps to keep your home warm, and also insulates against noise too.

Double glazing relies on a complex arrangement to provide the unique qualities which protect your home, and it's vital to make sure each part is in tip-top condition.

Here's a closer look at the structure of double glazing and what to do if you need a repair.

How double glazing works

Double glazing is one of the most effective ways to insulate your home, protect against noise and also regulate the temperature easily.

Rather than just offering a single pane of glass, double glazing involves two separate panes of glass which contain a vacuum between them. The air which is caught in this vacuum creates an extremely effective layer of insulation which prevents the temperature being affected by the air outside. This means that neither hot air nor cold air can penetrate into your home.

With double glazing you won't feel any cold spots or draughts if you're sat close to a window or door, and you won't experience any condensation on the pane either.

How double glazing prevents condensation

Within the sealed units which contain the two panes of glass, there's normally also a strip of silica balls. As well as helping to keep the home quiet, this material also absorbs any moisture in the air, preventing it from escaping into the gap between the glass. This is what stops the windows becoming fogged up or from condensation developing.

Double glazed windows are normally guaranteed for a number of years; once this period has passed, there's the risk of the silica balls becoming saturated and soggy and unable to continue to remove moisture. When this happens, the windows can start to become misted over or damp with condensation. Rather than replacing the whole windows, it is possible to replace the parts which have worn out, renewing their protective qualities.

Locking systems

The locks on UPVC double glazing systems generally need to be installed at the same time as the windows; it's not always possible to fit them retrospectively.

This is because the window material isn't tough enough to support a lock which is secured with steel screws. It could not only damage the window but also invalidate the guarantee.

A good locking system installed with the double glazing won't just rely on the handle in order to keep the windows closed. There should also be an internal locking system within the window framework which is activated by the movement of the handle.

There are two main types of locking systems used: espagnolette and deadlock shoot bolts.

In the former, multi-point locking bolts are set into the actual window itself, with inset locking points within the frame. The bolts used are special mushroom heads as this prevents the frame and the window being forced apart by allowing the bolts to engage behind the multi-locking points.

Deadlock shoot bolts work by operating in the side corners which open and combine with a deadlock situated at the handle, again on the opening side. High friction hinges complete the security features on this type of locking system.

What Is Locksnapping?

You may well have heard of “cylinder snapping” or “lock snapping”. It’s a method used by burglars to break into property that is secured using a euro cylinder (e.g. almost all properties that have UPVC doors, although a significant number of composite and aluminium doors use them too, and they’re often used in commercial as well as domestic environments).

The method of lock snapping involves breaking the cylinder to then manipulate the lock to open. Whilst you may think that all the multi locking points on your door make it secure, it’s important to realise they are all operated by the cylinder – this is the weakest point and if compromised all the locking points are rendered useless.
