Hello Window People !!!!
Also we weren't going to add argon, but apparently it's standard on this Simonton. What are opinions on argon?
If you want to determine the difference between having low-e argon or not having low-e argon, get a heat lamp and shine it on the windows, you'll feel a very, very noticeable difference. The non argon window will not reduce the heat like the one with low-e argon.
