The next windows you choose could reduce wasted home energy by up to 20%

If the windows in your home consist of single glazed or older double glazed units, replacing them with our energy efficient windows will save you money. It can reduce the energy you need to heat or cool your home by up to 20%.


Using less energy means less CO2 

The images opposite show just how effective fitting energy efficient to your home can be. The right hand side of the property still has the original windows, and the reds and pinks show heat escaping. However the new extension on the left is fitted with energy efficient windows and the lack of reds and pinks show how they dramatically reduce heat loss.

Science suggests man-made emissions play a major role in global warming and in turn influence climate change. Home energy use alone accounts for 27% of UK carbon dioxide (CO2) emissions which contribute to climate change. 

The Glass and Glazing Federation calculates that if all the UK replacement windows installed were B and C rated, each household could save energy equivalent to making 34,000 cups of tea, and all our windows exceed this as they are A rated as standard.
