Bulletproof glass is usually constructed using a strong but
transparent material such as polycarbonate thermoplastic 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, usually consisting of products
such as Cyrolon, Lexan and Tuffak, 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. This type of bullet-resistant glass
is usually 70-75 mm thick
