Toughened and laminated safety glass: crystal-clear safety with a calming effect

Two different methods of glass processing award these glass products their special features. Whereby both products have their own special individual use.

Thermally toughened safety glass (ESG)

Under special thermal treatment, compressive stresses are produced in the areas near the surface. Therefore, toughened safety glass is a suitable glass product for all purposes where tensile stresses will occur at the glass surface. These increased tensile stresses can be caused for example by thermal loads, by static and/or dynamic loads or by special conditions of installation. Toughened safety glass shatters into hundreds of blunt edged fragments only when the tensile stresses at the surface exceed the compressive stresses produced by way of toughening.

Laminated safety glass (VSG)

For laminated safety glass, glass panes and synthetic foils are laminated into a crystal-clear assembly using a two-stage pressure and  temperature method. Laminated safety glass stands out by the fact that the laminate remains preserved even after breakage of single panes. Because of this feature, laminated safety glass is a suitable product for all purposes where minimal splintering is the main concern. It is  obligatorily stipulated for numerous installation situations, such as overhead glasswork, for fall safe glazings, and in kindergartens and schools. One also receives special products when toughened or heat strengthened glass is laminated. Security glazings also consist mostly of special laminated safety glasses.
