Dual pane windows generally have a warranty longer than one year. We replaced all the windows in our Norcal home in 2006 with dual panes. Last year the largest window looked a bit unusual and we called the supplier and they got the manufacturer to replace it at no cost to us. The windows have a ten year warranty.
