Low-emissivity (Low-E) glass is glass that has a special coating that reflects the infrared portions of light, while letting the visible light spectrum through. This is beneficial because the infrared heat from the sun is reflected away from the building in the summer and during the winter the infrared heat that is already inside a building is reflected back into the space.

There are two general types of Low-E coating, tin or silver. Tin oxide is applied to the glass at high temperatures to create a very hard and durable Low-E coating. The alternative is a silver coating, which must be enclosed in an IGU so that the silver doesn't degrade over time due of oxidation.

Low-E coatings often have a slight blue-green tint, which many architects find unacceptable. Newer Low-E coatings are produced with less tint, but it is important to review product samples daylight at varying angles to fully understand what the aesthetics will be when installed.
