Jeld Wen Of Canada Ltd

We purchased Jeld Wen, aluminum clad woodent windows for our renovated log home. Both bay windows arrived late on site and were not square or symetrical. They would not fit in the very square holes cut in the walls. The 2nd order when it arrived, wasn't much better but they could fit in the wall with the supervision of a company rep., and our contractor. Two of the winders on these windows have been difficult from day one. The more troubling part to this story is that the biggest pane in both windows keep cracking. Spontaneous cracking isn't covered after 10 years. They other windows thoughout the house have had their weather stripping replace 3 different times. They don't seem to hold up to UV light well, but at least they don't crack every 2-3 years. We are about to install the 4th replacement pane in our bay windows. Jeld Wens rep., suggested that we use a local glass company to do the job as it would be cheaper. I thanked them for this, and our local company does a great job, and have a great reputation. They don't see this as a "faulty install". Our home is 30 plus years old so I don't believe it is a "house settling" issue. The previous windows never cracked? I would like to see the company own up to a faulty product. They have offered to come and inspect, which is great, but not at $185/hr.
