What is Bulletproof Glass?
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.
The Breakdown
The Breakdown
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.
Monolithic Acrylic
Monolithic Acrylic
Best suited for indoor use, acrylic can be highly customized and has superior optical clarity
Laminated Polycarbonate
Laminated Polycarbonate
Best suited for indoor use, it is also customizable. However, lamination impacts optical clarity.
Insulated Glass
Insulated Glass
Designed for exterior use, this glass has excellent insulating properties and optical clarity
