Bullet Resistant Glazing

 

     Bulletproof glass is the term for glass that is particularly resistant to being penetrated when struck by bullets. Since manufacturing glass of usable thicknesses capable of fully stopping most bullets cannot currently be done, the industry generally refers to it as "bullet-resistant glass" instead.

     Bullet-resistant glass is usually constructed using a strong but transparent material such as polycarbonate  or by using layers of laminated glass. The desired result is a material with an appearance and light-transmitting behavior of standard glass but offers varying degrees of protection from small arms fire.

     The polycarbonate layer is often sandwiched between layers of regular glass. The use of plastic in the laminate provides impact-resistance, such as physical assault with a hammer, an axe, etc. The plastic provides little in the way of bullet-resistance. The glass, which is much harder than plastic, flattens the bullet and thereby prevents penetration.
