Builders use argon gas windows to increase energy-efficiency and comfort in the residential and commercial spaces they develop. These thermal windows, also known as Insulated Glass Units (IGUs) are typically double-pane construction. This means they’re built with two or three glass layers with a sealed space between those panels. The spaces between the glass layers are filled with argon or another gas type, to help slow the process of heat transfer through the glass, among other important benefits they provide.
What are the Benefits of Using Argon Gas Windows?
Nearly all modern thermal windows utilize a gas fill. There are important benefits of using argon gas windows compared with other thermal window types. The United States and Canada both offer tax credits to homeowners and businesses, to encourage the use of this window type, by offsetting the cost of argon gas windows for increasing energy efficiency. Argon is naturally occurring, odorless, colorless, and non-toxic. It’s also relatively inexpensive.
Argon delivers significant advantages over air filling in windows. Air inherently contains moisture, which can transform into condensation between glass window panes, which can cause windows to have a cloudy appearance. Argon is also a superior insulator, compared with air. It improves a window’s thermal efficiency to perform comparably to wall insulation R-value.
Here are some of the many impressive benefits of filling windows with argon gas:
