Fire-Resistant and High-Security Glazing
Fire protection and high security glazing must meet increasingly complex requirements. Vetrotech Saint-Gobain developed Contraflam Vetrogard Blast, a high-security glass that provides equally effective protection against fire and explosions.
As a result of increasing urbanisation and the associated redensification of metropolitan areas, buildings are being built closer to each other and also closer to traffic arteries, whether for cars, local public transport or rail transport. This means that governmental, railway stations and airports must be protected against various forms of attack with high-security glass. New security concepts, products and solutions are in demand. "Invisible" safety glass and fire protection solutions, e.g. to protect against fire flashovers, are required. This not only involves all-embracing safety and protective functions against various hazards, but also aesthetics and discreet architecture at the same time.
Glass must not only protect against fire, but also against the effects of violence such as burglary, explosion and/or fire. Special coatings are also used for facades. Within this context, Vetrotech presented this high-security glass at Glasstec 2018 fair last year.
Contraflam Vetrogard Blast high-security glass provides equal protection against fire and explosions. With a fire resistance of up to 120 minutes, it can effectively prevent the spread of a fire. Due to its explosion resistance up to ER4, it protects people from glass breakage and flying projectiles caused by nearby explosions. The explosion-resistant glazing without splintering is an advantage. Whether for windows, facades or doors - thanks to the light transmission value of up to 64 %, the product accordingly unifies high use of daylight and transparency with discreet protection against fire and explosions. Contraflam Vetrogard Blast can also be combined with numerous other functions, including bullet resistance.
