If you want to stop the glass breaking (or retain the broken pieces in
situ) then you have 4 choices:

1. Laminated glass
2. Wired glass
3. Polycarbonate
4. Translucent fibreglass with embedded expanded metal lath.

A 5th choice is cheaper. A cold-applied plastic surface film. Not so
good as laminated when broken, but adequate as a safety measure (if
the risk is loose shards, rather than falling through it) and far
cheaper.
