Double Glazed Units
Double glazing is a type of window where multiple panes of glass are assembled into units, and are often referred to as double glazed units, insulated units or insulating glass. Double glazing was invented in the 1930’s and become commonly available throughout the USA in the 1950’s although they didn’t catch on in the UK until the 1970’s.
They soon became popular due to their heat retaining properties as well as being far more secure. The only other alternative at the time was secondary glazing which was very unsightly and an inferior insulator.
Most double glazed units will last from between 10 to 25 years dependant on the manner in which they are installed and also the type of materials used. Due to harsher conditions, windows that face south (North Hemisphere) or north (South Hemisphere) will not last much longer than 10 years, although companies do offer refurbishment services to prolong their life.

The most common form of damage to a double glazed unit is the build up of condensation between the two panes of glass. This is caused when the seal around the unit fails and lets moisture in-between the glass. This is not a terminal problem and can be fixed by replacing the seal.
Double glazed units have improved dramatically in the last decade. They are no longer horrible looking white plastic chunks and in fact can now be made of almost any material and in any colour to suit the style of the house in which they are fitted.
