What is double glazing, should I have it installed in my home?
Double glazing is a specific type of glazing that uses two panes of glass per window rather than one.
Invented by the Americans during the 1930s, double glazing took over 40 years to become the popular choice of glazing it is today.

Even now though, there are still hundreds of thousands of properties in the UK that don’t benefit from the advantages of double glazing and unfortunately, some never will. So what is double glazing and what are the main benefits?
So what is double glazing exactly…
A double glazed unit consists of two sheets of glass separated by an air-filled gap of a few millimetres. The air trapped within the gap between the two sheets of glass acts as a very effective insulating layer, keeping noise and cold out and the heat you pay for in.
Before leaving the manufacturer’s workshop each of the panes of glass is tightly fitted into the double glazing unit so that a perfect seal is formed. This seal keeps the insulating layer of air in between the two pieces of glass and the double glazed unit working as effectively as possible.
Why you need double glazing in your home
Double glazing has many advantages over single glazed windows. Sadly all people tend to look at when considering installing double glazing is the price. Yes, double glazing in a significant purchase but there are several grants available in the UK that can potentially help with the cost.
So, putting cost aside, what are the benefits of double glazing?
The insulating layer of air that remains permanently in your double glazed units helps to eliminate noise from outside. This is particularly beneficial if you live near a busy road, or close to a school, or if you just have noisy neighbours that enjoy spending time in their back garden. Similarly, any noise you make inside your house will be kept inside your house, meaning you can turn up the volume on the karaoke without annoying the people that live close by.

Lower heating bills
It is estimated that around 60% of the heat you introduce into your home e.g. from gas fires, electric heaters etc. escapes out of poorly insulated single glazed windows. Some of this heat escapes through the glass itself, some from minute gaps that form between the window panes and the wooden frames and the rest from gaps that open up between the window frames and the outside wall.
Double glazed units are fitted and sealed perfectly though so that the heat you create in your home stays in your home. Again, the air-filled gap between the two sheets of glass acts as an effective insulator, retaining the warm air inside and keeping the cold air outside.
Lower carbon dioxide emissions
Over the last few years, the government has introduced a number of plans aimed at lowering the carbon footprint of every individual in the UK. One of these plans focusses on the quality of double glazing within a property and soon it will be against the law to sell a property that produces more than the maximum amount of carbon dioxide stated by the government. At the moment all single glazed properties produce more than the maximum amount of carbon dioxide allowed and so in the near future, it will be impossible to sell them on the open market. With this in mind, double glazing is an absolute must if you intend to sell your property in the future.
Double glazing condensation on the inside of windows not only looks unsightly, but it can also rot window frames, make the air within the room damp, cause mould to grow on curtains and blinds and in severe cases, it can even cause the walls and ceiling to become damp and cracked. Double glazed units reduce the temperature difference between the interior of your home and the exterior, meaning the likelihood of condensation forming is reduced as well.
