Low-e window leak
I walked in to my wife's office last night and noticed a rainbow-y haze on the window. When we bought the house there was another window in the garage with the same problem and was told it was a low-e window that had been replaced under warranty because it had leaked.
What I can't figure out where to find a replacement. I thought they were Pella windows but I have no idea why I thought that and can't find anything like them on Pella's site. It's a vinyl, sliding window with embossing that make the glass look like a grid of panes.
Is there anywhere I can look on an installed window to find model information? The installed the one I found in the back of the garage so I don't have one laying around anymore.
