Bullet Resistant Glass meeting UL 752

Ballistic laminated glass is a material that is constructed from a combination of standard or low iron glass and polycarbonate or PVB interlayer materials. It is constructed through a high temperature and negative vacuum environment bonding process called lamination that layers polycarbonate or PVB interlayers material between two pieces of glass. This process in various layers and thicknesses can create an impact-resistant glass that can withstand the force of certain bullets from a handgun or rifle, depending on the thickness of the glass and materials utilized.

When a bullet is fired into the bullet resistant laminated glass, the bullet will strike and pierce the outside layer of the “threat side” face layer of glass. This will reduce velocity and break down and flatten or expand the bullets structure, absorbing the kinetic energy shock through the multiple laminated layers. Therefore, the bullet will not fully penetrate as “spall” through the opposite “safe” asset side consisting of clear polycarbonate material. This is due to polycarbonate material’s ability to absorb the final energy of the bullet as it enters the last layer of clear ballistic resistant material.

Ballistic Laminated Glass or Clear Ballistic Polycarbonate Levels of Protection

The different levels of impact resistant glass are determined by the glasses’ overall thickness; the thicker the glass, the higher the level of protection. Bullet resistant laminated glass is available for a wide range of applications, with a general increase in protection level for higher risk facilities, institutions or government sectors. The table below illustrates a basic breakdown of the ways in which the different levels of bullet resistant laminated glass are generally utilized.
