Door salesman gave me a flyer from this Denver company that offers triple pane window. I did some research but their website shows almost nothing about the window and I can't find any other site that mentions them. Might be an exclusive with that company I guess.
Has anybody heard of them? What questions should I be asking about it?
I have 7 large windows facing the north that I would like replaced, live in Fort Collins, 5200 feet and wanted something to really help with my heating bills in the winters. Summers are not usually too bad.
