Argon gas is actually very common.
Low e and argon gas windows.
Argon gas windows are energy efficient due to the density of argon gas being heavier than oxygen.
Regardless of the season low e argon gas windows ensure the climate is stable in your home.
Since argon gas is denser than air it contributes to the captive air in double pane windows.
In this way the gas between the double paned windows are less effected by convection currents and drafts.
Benefits of argon gas in windows.
Low e or low emissivity coating is a unique microscopic glaze that helps minimize the amount of ultraviolet infrared and visible light from penetrating the glass keeping you cooler in the summer and warmer in the winter.
Combining low e with multiple panes of glass and gas fills such as argon or krypton increases energy efficiency even more.
Almost all thermal windows today use some type of gas fill so the benefits of argon are similar for most new thermal windows.
Additionally argon gas when used in conjunction with a special low e low emissivity glass coating helps keep windows cooler and closer to room temperature.
As well it limits the escape of heat outward.
By keeping the heat or cold air inside the house the windows provide a better insulator than windows with oxygen between the panes.
This means that regardless of the outside temperature climate or season low e glass helps reduce the costs needed to heat or cool your home by using the rays from the sun to your advantage.
An energy efficient thermopane window with low e argon means that during colder seasons the window allows the sun s rays to penetrate into the home letting in heat and light.
