Anyone here know much about "ballistic drywall"? I just read a reference to it but have never seen it. I guess it comes in sheets like regular drywall but is able to stop a bullet. It's used in police station entrance areas so that no one can shoot their way in, etc. I'm curious about weight (sounds heavy), easy of installation (drywall screws?), composition (composite material or an embedded sheet of steel?), etc.
Thanks.
