By installing our green and eco-friendly energy efficient windows and doors you can, decrease the heat loss and lower your carbon foot-print whist keeping your home warm and cosy at a fraction of the price, helping save money on your heating bills.
Window Energy Ratings (WER) are a useful guide to the energy performance of your windows.
The latest Building Regulations require all new homes to have a minimum ‘C’ WER rating. This is a handy benchmark to consider when choosing replacement windows.
Window Energy Ratings were originally launched by the British Fenestration Rating Council (BFRC) however schemes have since been established by CERTASS and BSI. Since the Window Energy Ratings Scheme was launched, the A-G Ratings have been recognised in a number of government-supported initiatives such as the Energy Saving Recommended scheme run by the Energy Saving Trust, and significant numbers of window companies now have their products rated and labelled.
The window energy rating scheme provides a very good idea of how environmentally friendly your windows are.
Up to 25% of the heat within most homes escapes through the windows, it’s easy to see why more and more people are opting for A-rated windows by installing energy efficient glass into their existing window frames.
Using inert gas, such as argon, in the cavity and/or warm edge spacers will improve the insulating glass U-value, using a low-iron glass such as Pilkington Optiwhite will improve the g value. The magnitude of the benefits will depend on non-glass factors such as the frame U-value and percentage frame factor (proportion of frame to glass). Therefore, by combining the best available technologies, it has been proved commercially possible to achieve A-rated windows without the need for triple glazing or costly krypton filling.
Window Energy Ratings provide a more reliable and relevant measure of the total performance of windows and give both trade and consumers a more informed choice. The A-G scale (with A-rated windows being the most energy-efficient), makes the Window Energy Ratings system consistent with other energy-performance labels already seen around the house, on certain white goods and other electrical equipment.
