Weedwhacker, it's tempered glass, and should hold up. Dad said you can't cut tempered glass, but I have no idea if that is correct or not. When he got it, it wasn't framed. Just plain sheets of glass. He said it's really strong though, and will hopefully hold up to a hail storm if he gets one. Dad is one talented guy! He's a diesel mechanic, but is very handy with building things!
