Laminated glass refers to a kind of composite glass product that is made by sandwiching one or more layers of organic polymer interlayer (usually PVB, polyvinyl butyral) between two or more glasses and processing them under high pressure and high temperature to bond the interlayer and the glass irreversibly.
Laminated glass is a composite glass product that is produced by sandwiching one or more layers of organic polymer interlayer (usually PVB, polyvinyl butyral) between two or more pieces of glass and processing them under high pressure and high temperature to permanently bind the glass and interlayer.
Its main features are as follows:
High security
Strong impact resistance: When subjected to external force impact, the glass will break, but the PVB film in the middle will strongly adhere to the glass fragments and prevent them from flying and hurting people.
Strong impact resistance: When subjected to external force impact, the glass will break, but the PVB film in the middle will strongly adhere to the glass fragments and prevent them from flying and hurting people.
Hard to break through: Even if the glass is broken, it will remain an intact whole, and even can form a "protective net" to effectively resist penetration from outside (e.g., theft and violent impact), and even has the capacity to resist bullets for a short time (bulletproof glass is multi-layer laminated glass).
Good sound insulation performance
Hard to penetrate: Even if the glass is broken, it will remain a single unit and will form a "protective net" that can effectively neutralize penetration by outside forces (e.g., theft and aggressive impact), and even can resist bullets for a while (bulletproof glass is multi-layer laminated glass).
Good sound insulation performance
The intermediate PVB film is an elastic damping layer with the ability to absorb and dampen the vibration of sound waves effectively, especially providing an excellent barrier effect for mid-to-high frequency noise.The intermediate PVB film is an elastic damping layer with the ability to absorb and dampen the vibration of sound waves effectively, especially providing an excellent barrier effect for mid-to-high frequency noise. Compared with ordinary glass and double-glazed glass, its sound insulation performance is even superior. UV protection
Compared with ordinary glass and double-glazed glass, its sound insulation performance is even superior.
UV protection
High-quality PVB film can block over 99% of ultraviolet rays, effectively protecting indoor furniture, carpets, curtains, paintings and other items from discoloration and aging due to ultraviolet radiation.
Good durability
Good ultraviolet-proof property
High-quality PVB film can block over 99% of ultraviolet rays, which can effectively protect indoor furniture, carpet, curtain, artwork, and other objects from ultraviolet radiation-caused fading and aging.
Good durability
PVB film can enhance the anti-weathering ability of glass, increase its intensity and make it more durable to climatic aging.
A number of functions can be selected.PVB film can enhance the anti-weathering ability of glass, increase its strength and render it resistant to climatic aging.

Soundproof laminated glass: It uses a special high-damping soundproof PVB film with better performance.Soundproof laminated glass: It uses a specially designed high-damping soundproof PVB film with better performance.
Fire-resistant laminated glass: It is with a special fire-resistant interlayer film. Fire-resistant laminated glass: It is with a special fire-resistant interlayer film which will foam and expand when subjected to fire to form a barrier that insulates and retards the spread of fire. It can foam and expand when subjected to fire to form a barrier that insulates and resists fire. (Note: The principle differs from that of special fire-resistant glass.)
(Note: The principle differs from that of dedicated fire-resistant glass.)
Dimmable/Smart laminated glass: By inserting materials like PDLC liquid crystal film in between, it has the intelligent dimming function of transparency upon powering and fogginess when power is off.
Dimmable/Smart laminated glass: Through encapsulating materials such as PDLC liquid crystal film in between, it achieves the smart dimming effect of transparent when energized and cloudy when de-energized.
The applications of laminated glass
Due to the above characteristics, laminated glass is widely used in a variety of industries that have requirements on safety, soundproof and protection:
Due to the above characteristics, laminated glass has widespread uses in numerous fields with requirements for safety, soundproofing and protection:
The building industry
Curtain walls and windows: especially in high-rise and street-facing buildings, they are used for withstanding wind pressure, preventing falling debris and noise reduction.
Curtain walls and windows: especially in high-rise buildings and street-side buildings, they are used for wind pressure resistance, falling debris and noise reduction.
Skylights and roof lights: It is a mandatory safety requirement to prevent glass from shattering and falling to harm people.

Canopies and sunshades: Provide protection safety.Canopies and awnings: Provide protection safety.
Shop windows and bank counters: they are both display features and anti-theft and anti-robbery protection.
Shop windows and bank counters: they serve both as display features and as anti-theft and anti-robbery measures.
The automotive field
Windshield: All cars are required to use laminated glass for their windshields.Windshield: All cars are required to use laminated glass for their front windshields.
This is the most typical application of its safety function, so that in the event of a collision, the glass will not shatter into sharp fragments that can harm the passengers and driver.
