TL;DR
A Low-E coating is a microscopically thin layer of metallic oxide applied to glass that reflects radiant heat while letting visible light pass. Placed on different surfaces of an insulated glass unit, it can be tuned to keep heat in for cold climates or block solar gain in hot ones, which is why the same window line carries several glass packages.
What it means
A Low-E coating is a microscopically thin layer of metallic oxide applied to glass that reflects radiant heat while letting visible light pass. Placed on different surfaces of an insulated glass unit, it can be tuned to keep heat in for cold climates or block solar gain in hot ones, which is why the same window line carries several glass packages. Its effect shows up on the NFRC label as lower U-factor and adjusted solar heat gain coefficient.
