When standard glass is impacted by a bullet’s force, it breaks into pieces and leaves openings defenceless against subsequent shots. Don’t take this risk. The use of glass bullet resistant systems, also known as bullet resistant glass or BR glass, ensures reliable protection by preventing ammunition from entering protected spaces. These bullet resistant windows are engineered to maintain structural integrity even after repeated impacts.
Bullet resistant glass levels are defined through strict testing. Bullet-resistant glass in Classes BR1 to BR7 and SG2 is tested to the European standard BS EN 1063 by successively shooting three different glass specimens with three controlled shots fired in a 120 mm triangle, or one shot at the centre of the glass for Class SG1. For all classes, the bullet resistant glass is tested as part of a complete system (glass + frame + environment) in accordance with EN 1523 (FB1 to FB7 + FSG).
This stringent testing process ensures that glass bullet resistant solutions provide buildings with heightened security, while reducing the sense of vulnerability occupants may feel behind transparent building elements. Properly specified BR glass allows architects and security planners to combine transparency with high levels of ballistic protection.
Did you know that a bullet from a Kalashnikov AK-47 can impact a surface at speeds of up to 2,500 km/h? High-performance bullet resistant windows made with advanced bullet resistant glass are designed to withstand such impacts according to the relevant bullet resistant glass levels defined under BS EN 1063.
