Many modern homes are already fitted with double glazing, but if you do not have this in your home it is definitely worth considering. Approximately one fifth of the total heat loss from an un-insulated home can be through the windows, but double glazing could reduce this heat loss by half.
Double glazing works by trapping air between two panes of glass. This creates an insulating barrier resulting in a reduction of heat loss, noise and condensation. By fitting double glazing in your home you could save £80 to £100 per year and reduce your carbon dioxide emissions by about 680KG.
There are many styles of double glazing available but it is worth checking that there are no planning restrictions in place for your property depending on its age and location. The cost will of course vary considerably depending on the style and number of windows and doors you require, but there may be grants available. To find out whether there are any on offer in your area contact your local Energy Efficiency Advice Centre on 0800 512012. It is also worth checking that the windows you buy have the Energy Saving Recommended logo in order to make sure that you are getting the best insulating properties. The Energy Saving Trust has a database of windows with the logo at www.est.org.uk
If you are on a budget and can’t afford double glazing, you could consider secondary glazing which is cheaper but will still cut heat loss and draughts. Alternatively why not invest in double glazing just for the rooms that cost you the most to heat. You can always fit double glazing in the other rooms at a later stage.
