Window Energy Ratings

The Window Energy Ratings (WER) 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 one product with another and make informed decisions regarding the energy performance of a window.

The A-G rating system, similar to that already used with white goods in the home, gives a rating based on the performance of the whole window (frame and glass) and therefore allows fair comparison of one window with another.
SGG EcoClear®+ enables windows to easily achieve A, B or C Window Energy Ratings in most window systems.
