Bent or curved tempered laminated 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.
laminated glass is produced by permanently bonding too pieces of glass together with an interlayer or resin. Several types of film and glass may be applied in the process, to obtain different characteristics for the structures - according to the purpose of use.
Curved or bent tempered laminated glass protects from personal injuries; in the lowest protection class from falling, and in the sturdiest class from bullets and pressure waves caused by explosions. In addition to the protection class, the size of glass, its bending angle and bending form affect the durability classification of glass. When the number of glass layers and films is increased, it is possible to build multi-layer glasses for various, demanding protection needs.
