Low-E (low-emissivity) glass is coated with a low-emittance material designed to reflect heat. A window made with Low-E glass repels ultraviolet rays that generate heat during the summer but absorbs UV rays and lets heat in during winter. The better insulated the window glass, the more comfortable your room temperature.
