Simply Build It

It is possible for toughened glass to shatter unexpectedly. It is caused by either a manufacturing fault or by minor damage during installation. If the glass is not annealed properly or an edge is chipped when being built, the stress can cause the glass to fail.

If the window is new and still under warranty, it is worth taking it up with the supplier as they may repair it free of charge.

Yes it is. If the temperature differentials between inside and outside are high and the panel is a veeeery snug fit in the frame then its quite possible for this to happen.
