Jean, if you are talking about the panes, I am surprised you have
acrylic. There is polycarbonate - Lexan is a major brand - that is
virtually indestructible. You can smash it with a sledge hammer
with no visible effect - great stuff, but it scratches easier than
the acrylic.

As others have said - consider real glass. For breakage you can go
to tempered or laminated glass. When tempered glass breaks it
disintegrates into fingernail sized pieces with relatively
non-sharp edges: it can take quite a beating.

It can take quite a beating, but NOT a shrp impact. An automatic
center punch will destroy even 1/4" tempered glass in an instant.

Tempered glass, yes, but not safety glass, which would crack but would
otherwise still be intact.
Tempered glass IS safety glass - but so is laminated, and Jersey
glass - the stuff with chicken-wire in it.

As you should be able to tell, I was responding to the " When tempered
