Manufacturing of a tempered safety glass is one of the priorities of the Russian Glass Company. Increasing the strength of glass 5 times, maintaining large temperature differences, safety when broken - these advantages of the tempered glass are widely used in architectural glazing facilities, in housing and vehicle glazing
Tempered glass is 4-5 times stronger than non- tempered one, used as a source material. Tempering of the glass is one of the ways to increase glass strength by changing its characteristics. Thermally tempered glass is considered safe, as in the case of the glass fracture its splinters are not sharp and far smaller than that of a simple glass, which limits the risk of cuts.
Protection of people against injury by broken glass
Protection against burglary and vandalism
Protection against firearms, explosions (* in the composition of laminated glass)
Resistance to thermal breakage
The main area of application of the tempered glass is interior and facade glazing with increased requirements for physical security of people and also in the cases when the increased resistance to thermal stress is necessary.

All kinds of float glass, tinted glass, glass with solid pyrolysis-induced coatings, and some types of glass with a magnetron coating can be subjected to tempering:
AGC production - TopN+T, Energy NT, StoprayT.
Guardian production - HT-Version, SunGuard Solar, SunGuard High Performance.
Pilkington production - Pro-T, Optitherm, Suncool.

Thermally tempered glass - glass is subjected to special heat treatment; it is heated to approximately 600 ° C, then rapidly cooled by air jets. On the surface of the glass there is a body-stressed state. This makes it more resistant to mechanical and thermal loads and gives the required parameters in the destruction of fragmentation. Tempered glass is not possible for a subsequent treatment, so there is tempered not a sheet glass but the product after being sliced to the required size and processed. Production facilities of JSC "RGC" are equipped with the modern tempering furnaces Tamglass, providing tempering of complicated coated glass also in jumbo-format.
