Argon Gas Filled Windows

Why would you want Argon gas filled windows in your home? Are insulated windows really more efficient than their single pane counterparts? If so why? The short story is that the introduction of Argon into the space between two panes of glass creates an insulation barrier. Just like the insulation in the walls of your home, Argon gas filled windows keep the heat in and the cold out. Of course, the opposite is true when installing energy efficient insulated glass windows in warm climates. In this case the insulation barrier reduces the heat transfer from the hot air outside so your home will stay cooler inside in the summer.

Why Argon?

While a dual pane window filled with air would perform slightly better than a single layer of glass, the insulation value would be very low. Argon gas is approximately 30 percent denser than air which significantly boosts the insulation value of the glass. Additionally, Argon conducts far less heat compared to air, close to 50 percent less in fact. As an added benefit the denser gas reduces the noise that passes through the glass so you are less likely to hear loud trucks or a teenager’s boom-box when they are driving past your home.

Are Argon Gas Filled Windows Safe to Use in my Home?

If you are unfamiliar with Argon gas you may be intimidated by its presence and may be wondering if it is safe to use. The truth is, the air we breathe each and every day already contains approximately 1% Argon. In fact, Argon is the third most common gas present in our atmosphere. Argon gas is non-toxic and completely harmless, providing that an adequate amount of Oxygen is present. So when the neighbors kids drive a baseball through your new windows, the Argon gas that escapes presents no danger whatsoever.

Will the Argon Gas Dissipate Over Time

Not all Argon gas filled windows are created equal. Each manufacturer of insulated glass offers their own unique seal design. The seal plays an important role in maintaining the level of Argon in the space between the layers of glass. High-quality windows will have a dissipation rate of less than 1 percent. With losses this low your windows will continue to provide superior insulation value for many years to come. Learn more about seal types in this article “What is Insulated Glass.”

Fun Fact About Argon Gas Filled Windows

Here is a little trivia about Argon Gas. The word Argon is derived from the ancient Greek word Argos which means lazy, idle, or inactive. The correlation here is that Argon is a very stable inert gas that does not react with any substance other than fluorine. It may be lazy but it will help you reduce your monthly utility bill.
