Laminated glass is made of two or more pieces of float glass, with one or more layers of PVB, through special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processes, so that the glass and the inter layer film are well bonded as a whole. Composite glass products. Because this bonding material has good impact resistance and bonding properties, when the glass is impacted and broken, due to the bonding effect of the PVB film sandwiched between the two ordinary glasses, it will not produce sharp cracks like ordinary glass after breaking. Fragments hurt people. At the same time, the sound insulation and sunlight control properties of its PVB inter layer 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 it can block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum.
