What is Argon Gas and Why Should it be in my Windows?

0 Comment

Argon Gas is an odorless, non-toxic, inert (nonreactive) gas that is used in residential windows, in between the panes of glass. Window manufacturers use argon gas in windows to help prevent frost build up, increase the r-value of the window, and help increase the soundproofing abilities of the window. Argon windows are becoming very popular with homeowners because of the many benefits they offer.

Benefits of Argon Gas Windows

  • Increases r-value, minimizing heat transfer through window
  • Increases soundproofing abilities
  • Blocks harmful ultraviolet rays
  • Can be used in all climates; just make sure the windows are sealed properly to prevent leaking.
  • Argon windows are available in many different residential and commercial sizes

With Argon filled windows, the biggest con is making sure that the windows are properly sealed. If the window is not sealed properly, the argon gas will leak out and you won’t even notice it. Without the argon gas in the window, you are losing all the benefits it gives you. In higher elevations, especially, since glass tends to expand and contract more, you will want to make sure that the seals on your windows are done properly and are maintained well.

You can have argon filled windows in both double-paned windows and triple-paned windows.

Is it worth the extra cost to have gas filled windows?                                              

It’s estimated that a gas filled window costs an average of $20-40 more than a non-gas filled window. So while there is a higher cost upfront, the benefits of having them will outweigh this cost. Having more efficient windows will help keep your home more comfortable, prevent your heating/cooling system from being overworked, and help reduce your yearly energy bills.
