Window Energy Ratings
Windows are rated according to the new "Window Energy Ratings" (WERs), a system which has been introduced to meet the challenge of climate change and to help lower the cost of energy bills and which has been endorsed by the Energy Savings Trust. At present this is a voluntary system, but will become a legal requirement for all new build windows by April 2010.
WERs are a sophisticated ranking system, judging not just the energy efficiency of the frame or glass, but of the whole window.
WERs measure a window,s energy performance, rating how much heat the window retains, how much heat a window gains through capturing sunlight and how little air is lost through the window.
What are 'A' Rated Windows?
'A' Rated Windows have zero heat loss.
Window Energy Labels work in the same way as household appliance energy labels for fridges, freezers and washing machines. The Window Energy Rating labelling scheme was launched in the UK by the British Fenestration Rating Council (BFRC), a government supported independent body. By using information contained on the label, consumers can reliably compare the energy efficiencies of one product against another.
What Are The Benefits of 'A' Rated Windows?
'A' Rated Windows are a huge improvement over most double glazed windows installed in the last 30 years, almost all of which will loose nearly twice as much heat as an 'A' rated window. With energy prices rising and rising, the benefit of installing an 'A' rated window will help not only the environment, but will save thousands of pounds on household heating bills.
Over 20 years a saving of at least £11,420 and a saving of 22.87 tonnes of CO2 emissions & 6.24 tonnes of carbon emissions can be achieved when 'A' rated windows are installed*
