Broken Window
WOW, can this just happen on it's own? Kid was over and cut the grass today, but he says it wasn't him. I wiped down that window yesterday.

To me when I blow the picture up it looks like a slight impact from the right side in the middle of the glass. The cracks seem to radiate from that point. Having said that if it is safety glass it has a lot of surface tension built up to the mfg process, some upwards of 10,000 psi. With an Al frame that expands twice that of glass in the hot sun trapping it, it would not take much of an impact to shatter it. Another problem occurs if the edges of the glass are not smooth or polished a crack can start from there. If you notice that the safety glass breakers have just a small diamond tip that will shatter the glass better than a hammer because the psi is greater.
