Don't buy Anderson windows because they are junk and their warrentee only covers the replacement of the windows not the labor of putting them in. I have 17 windows in my addition that have lost the gas in between the glass and run water all winter down them. I had to put plastic on last fall like I had to with my old Grossman's window that cost $25.00 a piece. I would never buy Anderson again and would advise everyone to stay away from them. It's always the fine print that gets you when you deal with shady people.
