GET THE FACTS: Benefits of Gas-Filled Windows

In this week’s GET THE FACTS series we’re going to talk about gas filled replacement windows. We’ll cover the benefits and common FAQ’s.


When you choose to replace your windows, you want to get as much return on your investment as possible. This means you should select a window with multiple panes of glass and gas-filled between each pane. Doing this increases the efficiency of your replacement window, helping to reduce heating and cooling costs.

Gas is thicker and denser than air and insulates the glass pane from the outside temperatures.


No, all gas used in replacement windows is colorless and odorless. If your window seems cloudy or hazy this is because of a seal failure of the window and should be fixed immediately.


The short answer is no. Regardless of the type of gas-filled window you choose, they all occur naturally in the atmosphere and are harmless.


  • Air
    • If you don’t have gas fills between the panes of glass, they are filled with air.
  • Argon
    • This is the most commonly used gas in replacement windows and is the cheapest option. It is denser than air, but not denser than other gases used.
  • Krypton
    • This gas is denser than air and argon and is the best option if you are looking for the most energy efficient.
