Low-e coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. When heat or light energy is absorbed by glass it is either shifted away by moving air or reradiated by the glass surface.or complete technical information about designing with low-e glass, read PPG Glass Technical Document TD-131. And for any other glass questions, please contact PPG or call 888.PPGIDEA (888.774.4332).
