TEMPERED SAFETY GLASS

The strength of tempered safety glass is based on the thermal treatment applied to the glass. The glass is heated to the temperature of approx. 650 °C, when the glass becomes softer and tensions disappear. After that, the glass is cooled rapidly, when a constant compression stress remains on the surface of the glass, and a constant tensile stress in the middle part.

The strength of tempered glass is increased approx. from three- to five-fold compared with untreated glass. The safety characteristics of tempered glass are emphasized also when the glass is broken, when it breaks into small fragments without causing bigger wounds when getting into skin contact.

The most important stage in the tempering of safety glass is to make the optical qualities of the glass to remain unaltered. In the tempering process applied by Tambest Glass Solution the glass is being heated in two phases partly by means of circulating air, when the optics of the glass remain as ideal. The importance of distortion free optical surface is emphasized in large reflecting glass surfaces.

The design is often based on the increasing need for bigger glass surfaces, concealed fixing and structures applied without casement and framework. Thanks to better durability, safety and bigger glass sizes, tempered safety glass is the only reasonable alternative for these challenging structures. The maximum size of tempered glasses is 2440 x 4500 mm.

The tempered safety glass manufactured by Tambest Glass Solution represents the absolute top in the line.
