Safety glass
Safety glass refers to panes of glass that have special safety features.
Safety glass can consist of:
-
Single-pane safety glass , ESG for short:
The prestressing is created here in float glass by particularly intensive cooling of the red-hot glass using air nozzles blowing on both sides while it cools to room temperature. When mechanically influenced, ESG breaks into many, very small pieces, which minimize the risk of injury. Use is made e.g. B. in bus stops and also on the window panes of buses. ESG panes are always given a stamp in a corner to indicate the ESG properties and to avoid confusion with normal float glass. -
Laminated safety
glass , or VSG for short: Consists of two or more panes glued together with foils. Laminated safety glass is manufactured from non-toughened panes as well as a combination of (partially) toughened panes. In the event of mechanical stress, the structure is retained for a while due to the adhesive film despite the cracked glass. - Wired glass : A wire mesh is inserted into a normal, still liquid float glass pane. This reduces the transparency of the glass. Wired glass withstands mechanical stress for a while, the broken glass is held together by the wire mesh.
The voltage curve in the glass becomes qualitatively visible under polarized light when viewed through a polarization filter - in this way ESG and VSG can be differentiated.
The distinction is also possible by means of stamps or, if not permanently installed, when looking at the front sides.
In the English-speaking world, safety glass is referred to with trade names such as safety glass , security glass , toughened glass or shatterproof glass .
