Low-E Glass

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.
