Creating The
Glass Future

Tempering is the heat treatment of the glass. Tempering is done by heating the glass at 650 – 700°C in a furnace for a sufficient period of time and followed by sudden cooling by compressed air. The surface hardens with reduced temperature. Firstly, the outer surface, then the inner part of the glass cools down, so that on surfaces compressive stress accumulates, while the center has tensile stress. Tempered glasses are approximately 5 times more durable than regular glass. Heat resistance is more than normal glass. It is a Safety Glass class product that does not cause injury to the users due to the small size of the fragments when it’s broken.

Processes such as cutting, edge processing and drilling cannot be performed on tempered glasses. Tempering process does not change the volume, color and chemical structure of the glass.
While the tempered glass can withstand a sudden temperature change of 200 °C (thermal shock), the non-tempered glass can be broken when subjected to thermal shock of about 40 °C.

Tempered glass is used where the glass is expected hardly to break but when its broken should not harm the users. Such as; facade windows, white goods glasses (oven - refrigerator etc.), automotive industry (vehicle side and rear windows), shower and bathtub glass, furniture glass (coffee table - table - cupboard, etc.), railing, handrail, balcony closing systems glass, lighting fixture glass, etc.
