Information on how to save energy and reduce noise in homes and offices

Double Glazing

Insulating your home is one of the best ways to make your home energy efficient and cut the cost of your heating bills – and one of the best ways to save energy is through double glazing. Double-glazing acts as second layer of protection for your home, and reduces the amount of heat lost. A large amount opf heat is lost through through the walls, windows or loft - possibly as much as 50% - and by installing double glazed windows you could cut this loss significantly.

Single glazed windows alone can lose around 20% of your home’s heat. Double glazing can make an economic and sensible long term investment for your home, and benefit the environment. Double glazed windows can save £80 to £100 and 680kg of CO2 every year – not to mention adding real value to your property if you later choose to sell.

How does double glazing work ?

Double glazing works by trapping air between two panes of glass. This creates an insulating barrier that will stop heat from being lost, stop condensation appearing at your windows, and will also reduce the amount of noise from outside.

You should look for energy saving recommended double glazing, to ensure that you are installing the most energy efficient frames and glass. This will be particularly important when Energy Performance Certificates give an energy efficiency rating to homes in the new Home Information Packs that you’ll need, if you choose to sell your property after June 2007.

Top Tips for Double Glazing

Installing double glazing can considerably alter the outside appearance of your property, so choose the type of double glazing for your home with care. This is particularly important when installing new frames and window panes into older style properties - especially historical buildings.

You can mainly choose uPVC, aluminium or timber frames for your windows – choose carefully and in accordance with the other main style features of your property. If you have a listed building or a building with unusual features, do bear in mind that you may need to get building or planning permission from your local council before you start work. Contact your local council to find out if you’ll be affected by any regulations. Believe us, this is well worth doing !

Ensure that you use an experienced professional to install double glazing rather than trying to do it yourself. However do get involved by asking how the windows will look when the job has finished, what sort of security is being fitted to the windows, and what guarantees accompany the double glazing work.

How much does double glazing cost ?

The cost of installing double glazing very much depends on the size of your house, and how many windows you wish to fit double glazed panes into – but expect to pay several thousand pounds for it. The double glazing company market is a competitive one, however, so shop around and see what deals are on offer – and don’t be afraid to haggle ! Always ask for recommendations, firstly from your friends and family if they have had good (or bad!) experiences, and after that you could have a word with your local builder or architect. You might even like to have a word with your local estate agent - they too can sometimes be helpful.

If your budget is tight, you may choose simply to double glaze the windows in individual rooms rather than your entire property. Pick the rooms you use most often and tend to heat most. Remember there could also be grants available to you in installing double glazing.
