Laminated glass is a layered safety glass, in which two panes of glass are joined by a permanent plastic film. Almost all types of glass can be laminated. Laminated glass is treated as safety glass, i.e. glass that does not cause injuries when broken, and the film keeps all broken pieces together. Laminated glass may be additionally strengthened by prior toughening of the glued glass. We then obtain glass with constructional properties. Glass railings, canopies, steps and glass floors are made of laminates. It is possible to make bent laminated glass.
