Normal glass might be very functional, bet when important people travel in a car with such protection they might be somewhat anxious. Projectile will shatter the armor and fly right through it. Bullet proof glass, which looks exactly the same as regular glass, does have the ability to absorb the energy from a projectile.
On first glance there seems to be no difference between the two. The trick is in the manufacturing process. Bullet proof glass (or frequently termed transparent armor) is created by layering polycarbonate material in a lamination process. This lamination process creates transparent material that looks like ordinary glass.
There are some aspects which make transparent armor projectile resistant and one of them is the thickness of the material. If a handgun projectile hits transparent armor it will collide with a smaller force than when a rifle projectile hits the glass. From this perspective, for the handgun projectile a much thinner armor is required.
Transparent armor can only stop projectiles if the layers together are thick enough. A rifle projectile is fired with a bigger force than a handgun projectile. To stop the handgun projectile one needs a much thinner armor than if someone needs to stop a rifle bullet.
Transparent armor can also be manufactured in such a way that it is one sided. The outside will be able to stop the projectiles, whereas the inside has no such ability. The person who is being shot at can this way fire back.
This type of bullet proof glass is manufactured by making use of two different sheets of materials: a brittle sheet and a flexible one. The brittle sheet, which is on the outside, shatters and absorbs the force and energy over a large area. The flexible sheet than absorbs the remaining energy. From the inside the projectile will pass right through the flexible sheet because the energy is concentrated on a small area. This type of transparent armor can, for example, be found back in cars.
