Bullet Resistant Glass: How it Works

There are two types of bullet resistant glass: solid acrylic or laminated polycarbonate. Solid acrylic is just as its name suggests - a solid sheet of acrylic either 1-1/4" or 1-3/8" thick depending on the level of protection required. Laminated polycarbonate is made by layering polycarbonate, a heavy-duty clear plastic, between two sheets of glass and laminating it all together. It can be 3/4", 1" or 1-1/4" thick depending on the level of protection. While a bullet will pierce the exterior glass layer of laminated polycarbonate, the inner layers absorb the bullet's energy stopping it from penetrating through the entire piece of glass.
