Laminated security glasses can provide several levels
of personal protection thanks to the built-in plastic PVB
(polyvinylbutyral) film. The film keeps the glass splinters in
place and is even able to prevent an individual from falling
through the glass:
The level of protection depends on the number and thickness of the PVB interlayers used in the laminated glass.
This function is strongly recommended for glass used in windows, roofing, flooring, balustrades, banisters and so on.
