We had some replacement windows installed about three years ago. The installer, Northwest Window and Door Company did a good job and we were happy with the result. Last month the interior glazing of one of the awning windows spontaneously cracked. It was tempered glass and within a few seconds the crack had covered entire pane. At the time, I was standing outside below the window and my husband was sitting inside. Nothing struck the window from either side. I thought, "good thing these windows have a lifetime warranty."
However, when we contacted the Certain Teed company that manufactured the windows, they told us that any glass breakage more than six months after installation is considered an Act of God and is therefore excluded by the warranty. This seemed strange to me, since there was no fire, explosion, wind storm, earthquake or any other event that I could associate with the breakage of the glass. It seemed like it had to be a defect in the glass. Since the warranty doesn't define Act of God I'm wondering if this isn't just an easy way for the company to get out of honoring their warranty.
