Low-E glass is coated with a microscopic layer of silver that reflects radiant solar energy while permitting visible light to pass through the glass, providing more comfort and lower energy costs.
Low-E Glass and Argon Gas
Argon gas works like an insulating blanket between two panes of glass to further improve thermal eciency and decrease outside sound levels.
