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 .
S-glass has a strength of 700,000 pounds per square inch (4,800 MPa) while E-glass and C-glass have a strength of 500,000 pounds per square inch (3,400 MPa). [ 9 ] Hardness
Thicker glass is used in special applications. 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 acoustic attenuation or security may require different thicknesses of glass to be incorporated in a unit.
Toughened glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. [6] Tempering, by design, creates balanced internal stresses which causes the glass sheet, when broken, to crumble into small granular chunks of similar size and shape instead of splintering into random, jagged shards.

The film thickness is selected for level of protection desired and the dimensions of the glass pane. Manufacturers recommend 100 micrometer film (2 ply) for glass up to 3 mm (1/8 in) and 175 micrometer film for glass over 6 mm (1/4 in). These films can be applied for security applications, where a delay of forced entry is desired.
