What Low-E glass means
Low-E glass has a microscopically thin metal coating that reflects heat, keeping heat inside in winter and outside in summer while letting light through.
Also called low emissivity coating.

Different low-E coatings suit different climates, and they change a window's U-factor and solar heat gain rating. Match the coating to the climate and the side of the house.
