Almost all thermal windows today use some type of gas fill so the benefits of argon are similar for most new thermal windows.
Low e and argon gas windows.
Argon gas windows are energy efficient due to the density of argon gas being heavier than oxygen.
Benefits of argon gas in windows.
Since argon gas is denser than air it contributes to the captive air in double pane windows.
Argon gas is actually very common.
Combining low e with multiple panes of glass and gas fills such as argon or krypton increases energy efficiency even more.
By keeping the heat or cold air inside the house the windows provide a better insulator than windows with oxygen between the panes.

In this way the gas between the double paned windows are less effected by convection currents and drafts.
And remember to cater your window decisions around your climate zone.
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.
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.
Regardless of the season low e argon gas windows ensure the climate is stable in your home.
In the warmer summer months the windows limit the amount of seasonal heat as well as that produced by various sources paved driveway vehicles etc from entering while nonetheless allowing the light in.
The result is improved thermal insulation efficiency.
