Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension .
The glass floats on the tin, and levels out as it spreads along the bath, giving a smooth face to both sides. The glass cools and slowly solidifies as it travels over the molten tin and leaves the tin bath in a continuous ribbon. The glass is then annealed by cooling in an oven called a lehr. The finished product has near-perfect parallel surfaces.
Toughened glass was invented in 1874 by Francois Barthelemy Alfred Royer de la Bastie. [1] Wire mesh glass was invented in 1892 by Frank Shuman. [2] [3] Laminated glass was invented in 1903 by the French chemist Édouard Bénédictus (1878–1930). [4] These three approaches can easily be combined, allowing for the creation of glass that is at ...

Laminated or tempered glass may also be used as part of the construction. Most units are produced with the same thickness of glass on both panes but special applications such as ...

There is a class of cement board strictly constructed of a Portland cement based core with glass fiber mat reinforcing at both faces. These panels can be immersed in water without any degradation (excluding freeze thaw cycles). These panels do not require the sealing of edges and penetrations to maintain their structural integrity.
