D: in the valley of a steep roof, prior to installation of the shingles. E: as part of the traffic deck on a low-slope roof. in the glass lites on an exterior door or window. Low-emissivity glass, commonly called low-E glass, is a type of reflective glass that is gaining in popularity, especially in residential and office applications. Low-E coatings are very thin metallic coatings that reduce visible light transmission by about 10 percent compared to uncoated glass. They are applied using either the vacuum (sputter) or pyrolytic process. Low-emissivity (low-E coatings) limit heat gain through the glazing by reflecting heat energy. Reflective coatings reduce interior solar heat gain by reflecting solar energy. Thermal performance of glazing is expressed by its thermal conductance, which a measure of air-to-air heat transmission due to thermal …Low-emissivity coating glazing is a type of glass that has a thin, transparent coating applied to it that helps to reduce heat transfer through the glass.
