Re: [PSUBS-MAILIST] Re: Viewport Toughness

Hi,

No such thing as "bullet proof". I have seen banks with "bullet proof" glass (probably polycarbinate) windows an inch thick (1 inch = 2.54 centimeters).
Seems they have to be thick to absorb the energy of most common projectiles.

"bullet proof" glass may be tough but how tough? How tough is enough? The only real extensive viewport research was done by Stachiw on acrylic. Anyone deviating from acrylic needs to take samples of their target material and test it. You must see for yourself if the target material is as tough as you want.

Regards,
Ray
