Classification of laminated glass

General civil tempered glass is made by heat treatment process to increase the strength of ordinary glass by 3-5 times, and can withstand external impacts or temperature changes of certain energy without breaking. Even if broken, the entire glass is broken into small obtuse angle particles similar to honeycomb shape, which is not easy to harm people and thus has a certain degree of safety. Tempered glass cannot be cut and needs to be cut to size before tempering, with the characteristic of self explosion. According to different uses, tempered glass can be divided into various types such as fully tempered glass, semi tempered glass, area tempered glass, flat tempered glass, and bent tempered glass.
Laminated glass, as a type of safety glass, will not produce sharp fragments that can harm people after being shattered by impact due to the bonding effect of the PVB film sandwiched between its two ordinary glass pieces. At the same time, the sound insulation and sunlight control properties of its PVB intermediate film make it a new type of building material with energy-saving and environmental protection functions: the use of laminated glass can not only isolate the 1000-2000 Hz coincidence noise that can penetrate ordinary glass, but also block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum. As a laminated glass that meets the performance requirements of new building materials, it is bound to play a huge role in the use of safety glass.
