Can I add argon gas to a window?

If you are interested in having an argon gas window, you will have to have a professional install it for you. Argon is added to the area between the windowpanes during the manufacturing process. The manufacturer has to create a vacuum in between the windows and then fill that space with argon. Without the necessary equipment, you can not insert gas in between two window panes and then seal it up effectively. This process has to be done before you buy the window.
