Due to the increased use of glass in modern everyday life, the demand for protection by the glass has also grown. There are various processing methods for this, the most common of which are toughened safety glass (ESG), laminated safety glass (VSG) and fire-resistant glass.
During the production of toughened safety glass, the base glass is heated and rapidly cooled. This creates stresses in the glass, which ensure that if the surface is damaged, it will break into many small, relatively harmless chunks.
In the production of laminated safety glass, at least one tough elastic and highly tear-resistant PVB film is placed between two sheets of flat glass. This glass composite is then rolled under heat and subsequently compressed in an autoclave at a pressure of about 10 bar. If the glass is damaged, the individual shards stick to the film and thus prevent the pane from disintegrating.
