SAFETY AND PROTECTIVE GLAZING UNITS
The safety of the glazing packet can be increased by using tempered glass and laminated glass. Tempered glass is thermally treated and then rapidly cooled, making it five times stronger than ordinary glass.
Tempered glass breaks into many small pieces. Tempered glass can also withstand higher loads than ordinary glass.
Laminated glass reduces the risk of injury if the human body collides with the glass and, in the event of breaking, the glass remains attached to the polymer (PVB) film.
Standard glass is the most commonly used in windows. It is mostly 4mm thick. If such glass receives an impact, it breaks into large, sharp shards that can cause injury.
Tempered glass breaks into small granular pieces. It doesn't create large jagged shards like standard glass does. Such granular pieces cause less injury.
Laminated glass is the most impact resistant. However, if it breaks, it remains in the window frame, minimizing the risk of injury from sharp edges or falling glass particles.
