Well i'll say this.. I've seen what windshield glass in an AD truck looks like when a pipe gets rammed thru it.. and i've seen what 'modern' windshield glass does when the same sort of thing gets run thru it.
Old AD glass breaks into shards, newer glass breaks and seems to concentrate the majority of the damage to the point of impact.. with a sort of 'white ring' around the hole.. so I suspect there is a little more going on with the newer glass then there is with the older glass.
Almost like the newer glass design is like a cross between the 'tempered' and 'lamanated'.. maybe it's BOTH?
Maybe Bill or some other person more familure with auto glass than I could shed some light on the subject?
