Laminated glass is made by heating two or more pieces of glass through glue bonding, so its safety and usability are better than ordinary glass. The use in high-rise buildings, banks or front stores is more popular.

Since laminated glass is made by bonding two or more pieces of glass, its fragments will not fall when impacted by an external force, but will be glued together with the glass frame and will not affect people. Causing injury is safety glass in a sense. Therefore, laminated glass is selected in places with high safety requirements, such as the front windshield of passenger cars, daylighting roofs over 3 meters high, banks and airplanes, etc. All use laminated glass; in addition, tempered glass is synthesized The laminated glass not only has safety performance, but also has relatively good strength, so it has its presence in indoor partitions, railings, and stage floors.

The benefits of laminated glass:

1. Have good transparency;
2. It is compounded with multiple layers of ordinary glass or tempered glass, which is more outstanding in impact resistance and can be used as safety glass;
3. Because of the adhesive effect of PVB film, it will not fall when the glass is broken, which has good safety;
4. Due to the different original glass selected, it has the characteristics of durability, heat resistance, humidity resistance, and cold resistance, and can be used in different places.

Technical quality requirements for laminated glass engineering:

1. The variety and color of the glass need to match the design requirements, and the quality must meet the national testing standards;
2. It is necessary to ensure that the glass is uniform in thickness, smooth and flat, and free of bubbles, water lines, cracks, scratches, chipped edges, missing corners, etc.
3. The exposed side of the laminated glass should be flat and smooth, and there is no difference in height.
4. The color should be consistent on the same plane of the glass, and there should be no chromatic aberration.
5. All the edges of the glass need to be polished and no traces appear.
