Safety Glass
The modern buildings bathed in natural light require glass with special features. The laminated glass combines into a single sheet of glass, identical in appearance with a normal glass, various functions necessary for modern glazings. This product provides protection for people and
buildings against various hazards.
Nowadays architecture is unthinkable without glass as a building material.
GLAZING RANGE
The safety glass range contains laminated glass combinations of different thicknesses with one or more layers of PVB foil (polyvinyl butyral), determining the safety class of the glass. The most frequently used types of laminated glasses are defined in the table below:

The European Standard DIN EN 356 - glass resistance against attacks classifies the glasses according to their resistance to manual attack. The glass is hit with a steel ball weighing 4.11 kg, dropped from various heights. The resistance class of the glasses is determined according to the table below:

What does "safety" and "security" mean?
Although similar, the two words define different notions when they refer to glass. The safety glass is a glass that prevents risk of injury in case of impact. The security glass resists deliberate attacks performed manually, with firearms or explosives. Using only the right glass will not provide the required protection unless a proper frame and a proper mounting system are used. It is therefore imperatively necessary to combine the performant glass with proper joinery systems.

It is recommended to use the safety glass for the glazing of doors and windows located at a distance less than 1.5 m from floor.
Also, the same safety glass must be used for all fixed glazing areas located below 0.8m from the floor.
