I had every window in my entire house replaced with Atrium Windows. Supposedly the warranty is good for as long as I own my home. Ha! I have 5 windows where the seal is popping up and the windows are cloudy. All the caulking around the windows on the outside has yellowed and pulled away, as well. I can not get a single reply from Atrium either by email or customer service phone number. never recommend these windows User's recommendation: I would never recommend these windows. Be sure your window company has a good reputation for warranty work.
