What is Low-E Glass
Low-E Glass is a very thin film of silver that reflects heat waves, keeps your house cooler in the summer and warmer in the winter. It also cuts down on the ultraviolet light that fades your carpet, furniture and drapes.

Low-E Glass reflects heat OUT on Summer days

Low-E Glass reflects heat IN on Winter days
What is Argon Gas
Argon Gas is an invisible, odorless, inert gas that slows down the transfer of temperatures, better than air between the double insulated glass.
