At first glance, the bullet-proof glass looks the same with any window glass, but this is where the similarity ends. An ordinary piece of glass, with a bullet, becomes salt and ice. The endurance-resistant glass is produced to withstand several firing. So what does it give you the ability to bulletproof these glasses?
Different producers produce bullet-resistant glasses in various species, but these are made by simply placing layered polycarbonate (multicarbonate) material between ordinary glasses. This process is called lamination. Polycarbonate is a rigid and transparent plastic. The bullet-proof glass has a thickness between 7 mm and 75 mm. The bullet-bearing cama will fall out of a lead outer layer that is ignited, but the polycarbonate glass material that has been made into layers prevents the bullet from absorbing the energy and leaving it from the final layer.
