Russian Glass Company manufactures heat- strengthened glass used in architectural glazing to provide additional strength for wind, snow loads and thermal stress. The engineering capabilities of the company allow manufacturing heat-strengthened glass of Jumbo-format.
Heat strengthened glass is more resistant to mechanical and temperature loads than the usual polished one and it withstands temperature differences up to approximately 100°C.
Heat-strengthened glass is not susceptible to spontaneous destruction caused by the presence of nickel sulphide inclusions; therefore, it does not require a subsequent heat soak test. When broken, heat-strengthened glass splits into large sharp pieces like float glass. So, it is not considered a safety glass.
Application:
Heat strengthened glass is used in such cases when destruction of a small fraction of tempered glass is not allowed.
During destruction the heat strengthened glass is broken into large fragments, which are kept in the frame and do not fall like a tempered glass.

Production technology:
Heat strengthened glass - glass, heat treated during which it is heated to about 600°C and then it is cooled in a strictly controlled way by air jets. In this case, the cooling is slower than at the thermal hardening process. The surface of the glass is then locked in a state of compression. This makes it more resistant to mechanical and thermal stresses and gives the required fragmentation settings by destruction.
