What’s the difference between a bulletproof glazing and a high impact resistance glazing ?
A bulletproof glazing is due to stop small projectiles (bullets) impacting glazing at very high speed. Impact energy is important and is concentrated in one point, which makes it very penetrating. A high impact resistance glazing is due to maintain the integrity of the vehicle against attacks with objects such as rocks, crowbars,… Impact energy is similar to the one performed by a bullet but, impact area is much larger and therefore less penetrating. The main difference between these two technologies being that, in the first case (bullet) the aim is to stop a projectile, and in the second, the aim is to avoid having someone or something going through the glazing.
