Argon is an odorless, colorless, non-toxic, inert gas that can be used instead of air between panes of glass to increase insulation and energy efficiency.

Low E is a metallic coating on the inside glass surface of windows to reflect or absorb the sun’s warmth and reduce damaging UV rays. It offers an enhanced U factor and solar heat gain coefficient.

Insulated glass consists of at least 2 layers of glass with an air space between.
