Shattered Window - How did THAT happen?
Last evening I heard a loud crash but couldn't identify the source.
Today I discovered that one INSIDE pane of a double insulated
Andersen window in an UNOCCUPIED room had completley shattered - glass everywhere! There's even a screen on the outside of the window which remains unmarked.
The window has been installed for 20 years, there was nothing abnormal going on weatherwise.
I am mystified as to what could possible have caused that.
Has anyone got any ideas?
Clearly, I have a replacement job in front of me but this was definitely "a first"

Not a normal thing, but it does happen for no apparent reason. Andersen does warrant the glass for 20 yrs so contact them. Even if they are out of warranty, the glass is not replaceable and you have to replace the sash. There is a triangle with the Andersen logo and some numbers/letters etched in the corner of each sash glass. They will need that info.

I know when installing new windows, you are required by manufacturer to leave a 1/4" gap at the top for future settling of the framing/shrinkage over the window. If you don't, over time, the settling/movement of the wood components will bear on the window frame and put considerable force there. I heard of one case where a child tapped the window and it broke. Thankfully, no one was hurt. Be safe, GBR

collapsed glass
chamois,
Has it been cold where you live?
Did you happen to notice any condensation patterns in the center of any of your windows this past winter?
Does the glass in your window look flat or does it look a bit concave?
