Safety Tempered Glass
Security requirements have become more pronounced in recent years. With our program of safety glass, we can meet all the needs of modern architecture today, i.e. safety requirements, which relate to:
- Protection against breakage, burglary and firearms
- Protection against injuries in case of breakage
- Protection against fire and smoke
- Glass breakage resistance
Tempered safety glass (ESG) is glass heated to the limit of plasticity at approximately 600 ⁰C, after which it is suddenly cooled with air. The glass thus acquires high mechanical and thermal resistance. In case of breakage, a network of small grains with rounded edges is created, so the possibility of injury is minimal: Safety tempered glass cannot be further processed after the heat treatment process. All cutting, drilling and grinding operations must be done before hardening. Surface treatment such as sandblasting and satin finishing can also be performed after hardening. The advantage of safety tempered glass is increased mechanical and thermal strength, and safety against breakage (according to EN 12 150).
The application of this glass is in the glazing of external and internal walls of buildings (facades), protective fences, doors, terraces, balconies, conservatories, telephone booths, shower cabins, ships, as well as in the production of insulating glass.
In addition to safety tempered glass, there is safety but partially tempered glass (TVG), which is between float and safety-tempered glass in terms of mechanical and thermal properties. Also, with this safety glass, in case of breakage, a network is created, but of larger pieces of glass with rounded edges, and it cannot be further processed either.
Safety partially tempered glass is used for ceiling glazing, glazing of glass facades, and in cases of large thermal and mechanical changes where safety is not required.
