The need for low-emissivity glasses arises obviously from the need to save energy. The Window Energy Rating (WER) takes into account both the heat leakage through the window as well as the heat gain from solar energy. Generally, both hard coated low-e glasses and soft coated superlow-e glasses fall into the same WER category. The WER calculation reveals that hard coated glasses with emissivity 0.13 or lower offers the same overall annual energy consumption than soft coated glasses. Such glasses, named as nERGYTM glass, can be produced with the novel Aerosol Based Coating (ABC) process.
