Hello. I need an opinion on a window problem.
I have 2 big windows. They are double pane (low-E) and the casing is all vinyl.
They are "trapezoid" windows, and each are 78"1/2 by 58"(w) by 66" (and the top is the angled part). So as you can see, those 2 windows are quite big (and heavy). They were anchored on the frame using the built in vinyl flange (with screws).
I live in a 120mph wind zone in Westminster, Colorado. So those windows were framed in a beefy frame, and reinforced with 3 micro-laminate on each side that go all the way in the attic, plus 2 10" shelves above the windows to act as an "H" beam. That wall was certified by a structural engineer and built to specs.
Needless to say, that wall is not going anywhere. We had 90mph winds about a month ago, and the wall performed really well. It shook, but nothing major compared to the previous non-reinforced wall.
My issue: On one of the windows, The vinyl fusion weld on the topmost seam is broken. Split right at the seam.
My question: Are those vinyl seams usually pretty strong? Can they take decent abuse?
See, those windows were custom made, and were cheap. At about $450 each, I was hoping to have them for about 10 years and had no illusions about their quality. But I think I got a weak seam (defect).
Anybody has experience with abusing vinyl windows?
Thanks for any information! CHEERS!
