One day while in the salon, I heard a vacuum seal "pop" then it was "snap and crackle" for another hour and a half. My tempered window in the salon parlor doors just shattered for no reason. It was not hot outside. There were no signs of anything hitting it. After researching this strange occurrence, I found people have awaken to their shower doors shattering in the middle of the night. Apparently, if too much stress is placed on the glass when placed in a framing, then it may eventually give in and shatter. Lucky for me, the window stayed upright and contained. It was a scary occurrence initially because I did not know if someone had shot at me or what. But after a slow inspection and confirming over the internet about glass shattering for no reason, I felt safer. The glass company said as long as the glass was not missing, then they considered the shattered window secure until it was replaced. Below is a picture of what the glass did look like.
