What is the laminated glass?

Laminated glass is a composite glass product, which is formed by combining two or more pieces of glass through high-temperature pre-pressing(or vacuum) and high-temperature and high-pressure process. The reason why it is called laminated glass is that one or more layers of organic polymer (PVB, EVA, SGP, etc.) interlayer film are sandwiched between the glass. This type of glass has a high impact resistance and vibration resistance, which is significant for improving the overall performance.

Grand Glass laminated glass is made of two or more pieces of glass, and the organic material film is combined between the glass by heated in an autoclave. The commonly used interlayer films for Grand Glass Laminated Glass are PVB film and Acoustic Insulation Film. An acoustic insulation film is made of special materials and has better sound insulation than ordinary PVB film. It is the latest functional film used by Grand Glass.

The principle of the sound insulation effect of sound insulating glazing:
Various outdoor sound sources make noise due to vibration, and the noise is transmitted through the air medium. When the noise is transmitted to the sound insulation glass, it will be gradually attenuated by the glass. The mid-low frequency noise will be effectively filtered out, and only 5% of the noise will enter the room.

Laminated glass VS tempered glass
Tempered glass and laminated glass are both safety glasses, commonly used in buildings and skyscrapers. The security methods of those two glasses are so much different. Usually, the tempered glass will break into small rounded fragments, which will not easily scratch the human body when it falls off. The broken laminated glass will also form small fragments, however the laminated glass is mixed with PVB Film between two pieces of glass. When the glass is broken, the glass chips will stick on the plastic film and will not fall off, ensuring that people and property are safe.

Advantages of laminated glass
Security application
After the glass is broken, it will only be adhered to the plastic film without sliding and falling off. At the same time, the surface will remain clean and tidy, effectively preventing the occurrence of debris damage or falling events.

Sound insulation advantages
With the development of modern society, the sound insulation effect has become an important factor for people to measure housing standards. Laminated glass, which uses organic material interlayer film, can block sound waves, thereby maintaining a quiet and comfortable indoor environment.

Laminated Glass

Reduce the transmission of sunlight:
The unique filtering function of laminated glass can protect skin as well. It can filter sunlight, ultraviolet rays, etc. The application of laminated glass in home decoration can effectively avoid the fading of valuable furniture and displays in the home caused by over-illumination.

Application of laminated glass in a point-supported glass structure system
Point-supported glass structure system refers to a new type of combined building structure that uses metal connectors and fasteners to connect architectural glass and metal support structures into a whole. Glass is an important part of the entire structure. Its structural design method has a great impact on the safety performance of the entire point-supported glass structure system. Laminated Glass has a high degree of safety and sound insulation, making it a common choice for this structural system.

In glass curtain wall, the requirements for laminated glass
The glass curtain wall is composed of decorative surface glass and connecting component supporting structure, generally used in building construction. Therefore, there are high requirements for the safety and load-bearing performance of the glass.
1. The appearance quality and performance of laminated glass used for glass curtain walls should meet the current national standards;
2. The laminated glass used in the glass curtain wall should be tempered;
3. The laminated tempered glass used in the glass curtain wall is homogenized;
4. The laminated glass processed and synthesized with PVB film shall be used, and the film thickness shall not be less than 0.78mm.

Laminated Glass

Grand Glass recommends that the laminated glass applied to the curtain wall is at least 1.52mm PVB to ensure that two pieces of thick glass are fastened. It can reduce the risk of air bubbles, and effectively control the quality and safety of the finished product.

Grand Glass is one of China's leading suppliers of engineering glass deep processing, operated on first-class facilities, the most effective management system and various product series to ensure that it provides customers with the highest quality products. The excellent quality laminated glass from Grand Glass is specially manufactured, which is extremely beneficial to any enterprise or family.
