About Tempered Glass


Laminated glass is a composite glass product made up of two or more pieces of glass and one or more layers of organic polymer in the middle, after being processed by special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure processes.

Material characteristics

Even if the glass is broken, the shards will be stuck on the film, and the surface of the broken glass remains clean and smooth. This effectively prevents the occurrence of debris piercing and falling incidents, and ensures personal safety.

In Europe and America, most architectural glass uses laminated glass, not only to avoid accidents, but also because laminated glass has excellent seismic intrusion resistance. The intermediate membrane can withstand continuous attacks from weapons such as hammers and hatchets, and can also resist penetration by bullets for a long time, and its safety is extremely high.

Safety glass


It refers to laminated glass, tempered glass, and hollow glass processed from them that meet national standards. Among them, the comprehensive performance of laminated glass and insulating glass are the best.


Generally, tempered glass for civil use is heat-treated to increase the strength of ordinary glass by 3-5 times. It can withstand a certain degree of external impact or temperature difference. Even if it is broken, the whole glass is broken into small particles with obtuse angles similar to honeycombs, which has a small impact on people, thus has a certain degree of security. Tempered glass cannot be cut, it needs to be cut to size before being tempered, and it has the characteristic of "self-explosion". According to different uses, tempered glass can be divided into full tempered glass, semi-tempered glass, regional tempered glass, flat tempered glass, curved tempered glass and other types.

As a kind of safety glass, laminated glass, after being broken, will not turn to be sharp fragments to hurt people like ordinary glass due to the adhesion of the PVB film sandwiched between two ordinary glass. At the same time, the sound insulation and sunlight control performance of its PVB interlayer makes it a new type of building material with energy-saving and environmental protection functions: the use of laminated glass can not only insulate the consistent noise of 1000 Hz-2000 Hz that can penetrate ordinary glass, but also And it can block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum. As a laminated glass that meets the performance of new building materials, it is bound to play a huge role in the use of safety glass.

Application advantage

Whether the sound insulation of modern rooms is good or not has become one of the important factors for people to measure the quality of housing. Laminated glass using PVB interlayer can block sound waves and maintain a quiet and comfortable office environment. Its unique ultraviolet filtering function not only protects people's skin health, but also frees the precious furniture and displays in the home from the bad luck of fading. It can also reduce the transmission of sunlight and reduce cooling energy consumption. The many advantages of laminated glass will have unexpected good effects when used in home decoration.

Production Process

LED glass, also called Power Glass, is a perfect combination of LED light source and glass, and it breaks through the traditional concept of building decoration materials. The pattern can be designed in the glass in advance, and the controllable changes can be realized through DMX all-digital intelligent technology in the later stage, and the brightness of the LED light source can be freely controlled. The interior uses a completely transparent wire, which is different from ordinary metal wires, and no wires can be seen on the surface of the glass; after special treatment in the later period, both technical and safety requirements have reached the relevant national certification standards.

Shopping points

Look at the logo and check the certificate

Since the launch of safety glass product certification in 2003, most of the country’s building laminated glass manufacturers have obtained product certification. The company must silk-print or paste the 3C logo on the product itself, or add the 3C mark on the smallest outer packaging and accompanying documents (Such as the certificate of conformity) . When purchasing a product, you must first check whether there is a 3C mark, and check whether the purchased product is within the scope of the company's compulsory certification capability and whether the certification certificate is valid based on the company's information, factory number, or product certification certificate.

Look at the appearance to check the quality

Check the appearance quality of the product, the laminated glass should not have cracks or degumming; the length or width of the burst edge should not exceed the thickness of the glass; scratches and abrasions should not affect the use; the air bubbles and impurities in the middle layer should not exceed GB/T 15763.3 standard requirements.

During use, avoid external impact, especially tempered laminated glass. When cleaning the glass, be careful not to scratch or abrade the surface of the glass, so as not to affect its optical performance, safety performance and aesthetics. The laminated glass should be installed with neutral glue, and it is strictly forbidden to contact with acid glue.
