Windows & The Environment

Standard, single-glazed windows can be responsible for up to 50% of the heat loss from a typical home. In fact, a single-glazed window loses anywhere between 6 and 10 times more heat than an area of wall of the same size, so it is easy to see why energy efficient, double-glazed windows have become popular in the last 20 years or so. uPVC, or "unplasticised Poly Vinyl Chloride" has become the material of choice for energy efficient window frames, not least because of its low thermal conductivity when compared to materials such as wood or aluminium. uPVC window technology has continuously evolved, especially in the last 10 years, such that modern uPVC can produce substantial savings on domestic fuel bills as well as being aesthetically pleasing and easy to maintain. Correctly installed, uPVC windows mean that your home can be a calm, quiet and comfortable place to be, whatever the weather.

Energy Efficient uPVC Windows

Of course, the low thermal conductivity of uPVC only contributes to the energy efficiency of a window. The characteristics of the glazing itself are even more important because it is the glass, after all, which is the main component of a window. Thankfully, modern uPVC windows take advantage of the latest technologies to minimise heat loss wherever possible. uPVC windows with low emissivity glass, which reflects heat back into a room, heating absorbing tints or foils and double glazing filled with the inert gas argon are all possibilities.

These energy efficient technologies, singly or in combination, allow you to turn down your domestic heating and hence save on domestic fuel bills with no loss of comfort. In fact, according to the Energy Saving Trust, savings of up to £135 a year are possible so, over their lifetime, energy efficient uPVC windows can pay for themselves many times over. Not only that, but by wasting as little energy as possible you can reduce the carbon footprint of your home and take your own small step towards combating climate change.

The British Fenestration Rating Council (BFRC) has produced a rating scheme, similar to the EU energy label for refrigerators, washing machines, etc., for the use of consumers. uPVC windows are rated A to G for energy efficiency and, whilst windows rated E and D are sufficient to comply with Building Regulations in England and Wales and Scotland, respectively, windows rated C are recommended for energy saving purposes, with windows rated B or A being better still.

Most windows are designed to last for decades, so replacing them is something that you are likely to think about once in a lifetime. However, when the time comes to replace old windows with something more modern and energy efficient, make sure that you employ a reliable contractor who offers a long-term guarantee to do the work for you. Bear in mind, too, that replacement windows can improve the value and security of your home which, in turn, may affect your premium - http://www.gocompare.com
