Does anyone have any information about the cost for Argon gas fill in
windows? Most of my windows will be rather large - about 7' x 5' or so with
1/2 inch air spaces. There is also a small possibility that triple pane
windows will be considered. They would be the same size but with a smaller
gap so I assume we could consider Krypyon for the fill. If anyone has any
info on the upcharge for that I'd love to have it too.

Thanks,
