How does low e glass work?

Low E (emissivity) glass is coated with a microscopically thin layer of metallic oxides that reflects infrared light while allowing visible light to pass through. This coating helps to reduce heat transfer, keeping indoor spaces warmer in winter and cooler in summer. By minimizing heat loss and solar heat gain, Low E glass enhances energy efficiency and comfort in buildings. Additionally, it helps to protect furnishings from UV damage by filtering out harmful ultraviolet rays.
