Blast resistance (EN 13541)
Blast-resistant glass is based on an ideal combination of the rigidity and compressive strength of glass with the plasticity and energy-absorbing properties of polymer interlayers, such as PVB. The classification ER1 to ER4 depends on the corresponding amount of TNT that is simulated in a controlled shock-tube test mechanism, penetrating the glass by the pressure of a real-life explosion. The glass should remain in the test frame to prevent glass from becoming a weapon and harming people on the safe side.
Did you know that the shock wave of an explosion can transform standard glass into deadly projectiles? Designed to be flexible, blast-resistant glass remains in its tested frame by absorbing the force of blast waves according to the respective blast resistance classification.
Vetrogard Blast – a laminated blast-resistant glass solution – consist of a multi-layer lamination of various interlayer films and glass panes resisting blast waves of different amounts of explosive materials. This highly-engineered glass solution stays in its frame by flexibly giving in when struck by a blast wave.
