What Are the Characteristics of Laminated Glass?

Laminated glass consists of two or more pieces of glass with one or more layers of interlayer film (PVB, SGP, EVA, PU, etc.) in the middle. After a special high-temperature process, the glass and the interlayer film are bonded together and become real laminated glass.

Laminated glass is mostly used in automobile manufacturing, large glass curtain walls or windows on high-rise buildings. On the one hand, laminated glass is better in quality and durable than ordinary glass; on the other hand, when laminated glass is broken, the granular shape will not be sharp and cause harm to the human body. Let's learn about laminated glass together.

Safety

When impacted by external force, because the elastic middle layer has the function of absorbing impact, it can prevent the impact object from penetrating. Even if the glass is damaged, it can only produce fine cracks similar to spider webs, and its fragments are firmly adhered in the middle to avoid personal injury or property damage caused by falling glass shards. Regardless of whether installed vertically or inclined, it can resist the penetration of external impact, and the entire glass remains intact, which can continue to resist impact and shelter from wind and rain until it is replaced.

Anti-theft

PVB laminated glass is very tough, even if the thief breaks the glass, because the interlayer glass firmly adheres together, it still maintains integrity, making it impossible for a burglar to enter the room and providing protection for people and property. The standard laminated glass can resist the penetration of general external impact objects. Even if it is damaged by force and has an opening, the opening is very small. Once damaged, the interlayer film will still protect the building until the glass is replaced.

Sound insulation

Glass is a kind of ancient iron material, not an effective sound insulation barrier. If the noise is transmitted through the glass, it will affect the people in the room. Due to the damping function of PVB film on sound waves, laminated glass can effectively inhibit the spread of noise.

UV protection function

In window design, the natural light transmission plays a very important role. Too much sunlight will cause too high heat. Laminated glass has various stable coloring,and PVB film can absorb 99% of ultraviolet rays, which helps protect valuable furniture, wall charts, displays or merchandise from fading from UV radiation. Most of the absorbed energy is lost through reradiation and convection outside the conduction chamber.
