I purchased a window from Champion. Cost over $1000. The day after the window was installed it rained and I noticed water in the INSIDE track of the windows. I called and was told by Mark that it was normal. He even stated engineering reports that said it was normal. I said that if water could come in, what is stopping air.....cold air from entering. Mark responded, "We never said our window was air-tight!"
Pros: None come to mind
Cons: Poor quality. Incompetant installers. Unbelievably bad customer service.
