Laminated glass

The laminated glass we have on offer is a component of at least two panes bonded together by PVB interlayer.

Laminated glass is marked by a combination of numbers which is easy to read. The most popular combination is 44.2 – meaning that two 4 mm glass panes are bonded by a 0.76 mm thick interlayer. A single PVB interlayer is 0.38 mm thick.

The main characteristic of the glass we use for the production of laminated glazing is for it to cause no risk of injury in the event of breaking. Unfortunately, glass is fragile and breaks easily often causing injury. This leads to the compulsory use of safe glass materials in public utility buildings. Should our glazing break, the glass will stay in its frames, minimizing the risk of injury.

The bonding of glass by PVB interlayer allows to construct, among others, such solutions as laminated glass roof partitions. Laminated glass functions as a protection against falling objects.

In compliance with the EN356 norm we distinguish 8 classes of resistance of safety glazing against manual attack: starting with P1A to P5A, and from P6B to P8B. The specific class of resistance should be individually matched to the requirements of the user. The most important information on the right choice of class is contained in this norm.

The lowest classes determine glass which has a high resistance to smashing, with the assumption that in the event of breaking they do not endanger anyone in the nearest proximity.
Glass of the highest resistance class is intended for protection against burglaries with the use of a 2 kg axe in a given period of time, e.g., class P8B is resistant to 70 blows. Other examples are also bullet proof glass units. These classes are described in detail in the EN1063 norm. We encourage you to choose strong, solid and reliable material.
