To help prevent injury, safety glass must be used in areas where people are most likely to get hurt. This means any double glazing installed within one foot of a door or 2 ft. 7 in. of the floor must use safety glass. Two main types of safety glass are used in homes today-tempered and laminated. Tempered glass is four to five times stronger than ordinary glass, and when it does break, it crumbles into dull pieces that won't cause serious harm. Laminated glass uses two or more sheets of glass with a layer of plastic or resin in between. When laminated glass breaks the broken pieces are held in place by the layer of plastic or resin.

If the glass level in frame is less than 800 mm above the floor, preventative measures need to be taken to keep someone from falling out of the window.

Structure
There must be adequate structural support above the window or doorframe prior to installing.

Escape Route
If there is a fire in your home, you must be able to escape through windows in rooms that are not on the ground floor. You must also be able to escape through windows in rooms on the ground floor if the only other way you can get out of the house is through another room. Furthermore, if you need a key to open the window, it should be kept near the window to allow for a quick escape.

Ventilation
An adequate combustion air supply must be available for appliances that have an open flue. If you have appliances like this in your home, you must have a qualified professional verify that the air supply is adequate. In addition, you must maintain appropriate background ventilation in each room.

Technology has come a long way in the double glazing industry and a lot of serious time and money has been spent on the design and manufacture of window locking systems.

Available in today's market are an impressive array of complex yet functional locking and security mechanisms, many of which are fitted as standard by us.

Locking Mechanisms - there are two main types

At Northern Glass, all our installations use a combination of the above systems to ensure your home is protected from unwanted intrusions.

Beading Internal or External

As explained on the Metropolitan Police Services website (link below) internally beaded windows are preferable to externally beaded windows. At Northern Glass, all of the windows supplied are internally beaded.

For all the technical advancement, it still has to be recognised that if someone wants to break into your home, they will do. Your doors and windows are the natural points of entry and therefore prime targets for potential thieves. Although toughened glass, internal beading, reinforced hinges and a quality window locking system are all well and good, in reality perhaps their greatest power lies as a deterrent rather than a physical barrier to entry.

Combine these with an easily recognisable alarm or better yet an active Neighbourhood Watch scheme and chances are that anyone eyeing up your property will decide it?s more trouble than it?s worth and move on.
