low-emissivity glass low-emissivity glassA glass that transmits visible light while selectively reflecting the longer wavelengths of radiant heat; made by a coating either the glass itself or the transparent plastic film in the sealed air space of insulating glass. See also: glasslow-emissivity glass, low-e glass1. A glass that has a special thin-film metallic or oxide coating which allows short-wavelength energy of the sun to be transmitted into a building, but which prevents long-wavelength energy of the heating systems within the building from escaping to the exterior; thereby conserves heat energy. 2. Same as reflective glass. |
