Bulletproof glass thickness

Conventional bulletproof glass tends to be thick, heavy and tinted. SILATEC ballistic glazing, in contrast, is thin, lightweight and transparent. Thanks to these properties, it is also suitable for retrofitting into existing door and window frames to enhance security while maintaining the building’s aesthetic appeal.

Retrofitting made easy

A building with triple-glazed thermo-glass windows, for example, can be easily fitted with ballistic glazing. Since insulated window panes are generally 36 to 50 mm thick and weigh between 30 and 60 kg/m², the existing frames are fully suitable for SILATEC bullet-resistant glass. With our BR4-NS 25/52 glazing, which is only 25 mm thick and weighs just 52 kg/m², your windows will withstand bullets fired from powerful weapons like the Magnum .44 handgun. For more details on thicknesses and bullet-resistance (BR) classes, see the specification table below.
