Low-E glass coating

Jump to: navigation, search


A type of glass coating that effectively reduces the transfer of heat by reflecting long wavelength infrared (IR) radiation. Low-E, or low-emissivity, coatings were first introduced in the 1990s. They are designed to provide maximum visible light transmission while minimizing heat transfer. The thin metallic coatings are either vacuum sputtered forming a soft, easily scratched film. Unlike the older, but similar, reflective glasses, the metallic layer of Low-E glass is so thin it is barely visible. Low-E glass microscope slides have been used for the preparation and reflective analysis of IR spectrophotometric samples.
