Heat-strengthened soda lime silicate glass is a glass in which uniformly distributed surface compression stresses are created through a number of controlled heating and cooling processes with the purpose to achieve high mechanical and thermal resistance and a specific breakage pattern.
As compared to the tempered glass the heat-strengthened glass has a higher resistance to thermal stress and increased mechanical strength.
The heat-strengthened glass in “Glassco” Ltd. meets the requirements of the international European standard EN 1863 “Glass in building – Heat strengthened soda lime silicate glass”, adopted in Bulgaria.
The whole process is controlled by a computer system, ensuring high quality of the glass.
