Safety glasses

Hardened Glass. Glass hardening is a technique for making glass safer and more durable. Hardened glass is 5-6 times more resistant to loads and strikes than ordinary glass. It also withstands much higher temperatures and fluctuations. Broken hardened glass fragments into small, blunt pieces, and therefore cannot actually cause injuries.
To harden glass, it is heated up to 600-700 degrees Centigrade and then rapidly cooled down using air.
Hardened glass is used in manufacture of shop windows, glass partitions, doors, façades, furniture and other products where safety is required.

Safety Glasses. Safety glass is used to protect health, life or property from different sorts of threats.  It is manufactured from several glass sheets which are joined together with polymer film or resin.  In accordance with the functions, safety glass can be divided into several types:

  • Impact-resistant glass. This glass protects from shattering that can occur when breaking glass (for instance, a window or a shop window). Its use is recommended in public places. In accordance with the European Standard EN 356 “Safety Glass Types”, these are P1A to P5A safety glass classes.
  • Smash-proof glasses. Such glass is used to obstruct break-ins into premises. Its use is recommended in premises where there is a risk of unauthorised break-in or an attack (banks, offices, important governmental institutions, etc.).   In accordance with the European Standard EN 356 “Safety Glass Types”, these are P6B to P8B safety glass classes.
  • Bulletproof glass. This glass is used to protect life and health from weapons. It is used in premises (and also vehicles) where there is high risk of an armed attack or an act of terrorism. In accordance with the European Standard EN 1063 “Bullet-Proof Glass Types”, these are BR1 to BR7 safety glass classes.

Fireproof Glass. In cases of fire, this glass helps prevent the spread of fire, as well as heat and gases caused by high temperatures.   Similarly to safety glass, fireproof glass also consists of several glass sheets joined together with a special polymer.

Soundproof Glass. Such glass ensures sound insulation up to 49 dB (Rw coefficient). It is used in premises where the noise level from external or adjacent premises must be reduced. Soundproof glass is multi-layered glass in which either an acoustic PVB film or a special acoustic resin is placed between glass sheets.
