More accurately described as bullet-resistant glass, it is actually one of several types of ballistic glazing materials. It is a little-understood fact that in many cases there is no actual “glass” involved.
Bullet-resistant glass is constructed using one or more of the following materials: acrylic, polycarbonate, or actual glass. These materials are used either by themselves in the case of monolithic acrylic, or layered together in multiple configurations to achieve specific properties.
Best suited for indoor use, acrylic can be highly customized and has superior optical clarity
Best suited for indoor use, it is also customizable. However, lamination impacts optical clarity.
Designed for exterior use, this glass has excellent insulating properties and optical clarity
Multiple thick layers reach the highest-rated levels of bullet resistance.
The actual weight of each type of bullet-resistant glass is directly related to its corresponding ballistic rating level. The below weights are the average across all levels available for that glass type
Each level of glass has been tested and found effective at stopping certain types of ammunition. The chart illustrates the weapons used to test at each UL 752 rating level.
