If you want to go with glass look for impact resistant glass used in domestic windows. While the glass will break given a strong enough force (the test is a 2 X 4 shot out of a cannon at 60 mph) the integrity of the panel is not breached, due to an inner layer of plastic bonded to the panes of glass.
By the way, the windows on my Pearson 28 are made of "safety" glass, but have not had an impact event.
