Between The Glass: The Difference Gas Makes To Your Windows

Gas-Filled Windows For Better Energy-Efficiency

The gas between the panes of your double or triple glazed windows can have a huge impact on your heating and cooling expenses. It is wise to educate yourself on the best energy-efficient windows before buying new ones.


Argon gas is commonly used between the panes because it is colorless and odorless. It is also denser than air, making it better and more efficient as an insulator. Krypton gas, however, is denser than argon gas, providing an even better thermal barrier; but krypton gas can be more expensive and may not provide enough increased efficiency to justify the extra cost. Both argon and krypton gas are nonreactive and naturally occurring.


Much of a homeowner’s expenses come from heating and cooling. When it comes to efficient windows, you will want to look for ENERGY STAR®, because these products are twice as efficient as ordinary windows.
