Argon gas windows are extremely popular for double and triple pane-glass windows. Contractors often choose these types of windows because of their increased energy efficiency. Argon gas also provides additional benefits to homeowners than just energy efficiency. Before we get to the benefits, let’s discuss what exactly argon gas is and how it works in windows.

What is Argon Gas?

Argon is a noble gas found in Earth’s atmosphere. Approximately 1% of the planet’s atmosphere is made up of argon, yet it is the third most abundant gas. Argon is colorless, odorless, and not flammable. There are no known effects caused by argon environmentally making it a safe element for windows.

Why is Argon Used in Windows?

Double and triple-pane windows often use argon gas because of the benefits it has over standard air. If air is sealed between the panes of glass, the moisture within will condense to create a cloudy look. Air is also less effective at insulating homes. Argon is denser than air, so the efficiency of sealing in the heat is higher.

Benefits of Argon Gas Windows

  • enhanced soundproofing
  • reduced possibility of condensation or frost
  • applicable in all types of climates
  • non-toxic gas
  • relatively inexpensive
  • residential and commercial applications

Before making the switch, you should know the few drawbacks that come with argon gas windows.

Drawbacks of Argon Gas Windows

The biggest drawback to having argon gas in your windows is the potential for it to escape. Once the seals on your windows fail, the argon gas escapes and replaced with moisture-filled air. You should also know the average leakage rate for argon gas windows is 1% every year. With normal leakage and intact seals, the average lifespan of argon-filled windows is 20 years.

So, your argon gas windows will never be completely sealed. It is also unlikely for them to stay sealed as argon does not expand or contract. Unfortunately, glass does, which increases the chance of breaking the seal between the panes.
