Question for you window experts out there.
In my own home, which is 7 years old, I am experiencing random window cracking in the outside pane of glass. I had a few failed seals when I moved in and a couple more in the 18 months since. The cracks have developed in two windows in different areas of the house. I am pretty sure that nothing hit them. There are no signs of abnormal foundation movement in the home. I do have 90% solar screens installed on all of the windows. I have never heard of them causing this type of problem, but now am wondering if they might be related.
Original owner did not send in the window warranty paperwork, so the Danvid warranty doesn’t help me according to the certificate.
Thought this might be something useful to learn more about for my clients who may have this problem.
