I just stumbled accross this message board. I cannot believe all the people that are having trouble with Home Depots windows. I bought and installed 15 8500 series windows in my home. I cannot be happier. They installed easy and now are performing as expected. I installed them in june and july 2002'. You will get some condensation on the inside of the glass because of the humidity in your home. like cooking , taking showers etc. sorry for your bad experience.
If I can help please email me.
