FIREPROOF GLASS
Fireproof glass is produced as a multilayer glass joined by a special mixture. In the case of exposure of fire-fighting glasses to high temperatures, a chemical reaction occurs between the glasses where the mixture expands and for a certain time forms an impenetrable barrier. Thickness ranges from 17 mm (durability 30 min) up to 35 mm (durability 90 min). The glasses are intended for indoor use.
