Coated laminated glass is a safety glass made by sandwiching one or more layers of PVB (polyvinyl butyral) film between two or more pieces of glass, and compounding them together under high temperature and high pressure through a special process

The product features include:

Safety features: Coated laminated glass has excellent safety performance. Even if the glass is damaged, its fragments still stick to the intermediate film, avoiding personal injury or property damage caused by glass falling.

Security features: PVB intermediate film has excellent tensile strength and elongation, making laminated glass extremely tough and difficult to be cut by cutters, with high impact resistance.

Sound insulation characteristics: PVB film can effectively control sound propagation and achieve good sound insulation effect.

UV resistant properties: PVB film can filter over 99% of UV rays, reducing indoor item fading.

Energy saving and environmental protection features: PVB intermediate film can absorb most of the heat, reduce indoor and outdoor heat conduction, and save air conditioning energy consumption.

Decorative effect: Different materials can be sandwiched inside laminated glass to achieve decorative effects, such as cloud dragon paper or various patterns.

Application fields of coated laminated glass

Coated laminated glass is widely used in multiple fields due to its various characteristics:

In the field of architecture: used for building doors and windows, indoor and outdoor decoration, curtain walls, stair railings, sunrooms, etc.

Automotive field: Used for car windshields, even if the glass is shattered, the fragments still stick to the PVB film and will not splash out and harm people.

In the aviation field, laminated glass is widely used for aircraft windshields, which have high strength, bird strike resistance, anti fog, defrosting and other properties.

Photovoltaic industry: With the rise of the new energy industry, laminated glass plays a role in protecting photovoltaic cells in photovoltaic modules.

Environmental Protection Standards for Coated Laminated Glass

The environmental standards for coated laminated glass mainly refer to the “Green Product Evaluation of Building Glass” (GB/T 35604-2017)

This standard specifies the terminology and definitions, evaluation requirements, and evaluation methods for green products of building glass, and is applicable to the evaluation of tempered glass, laminated glass, and insulated glass used in buildings. Production enterprises should meet green requirements, including pollutant emissions that comply with relevant environmental protection laws and regulations, and meet the requirements of national or local pollutant emission standards.

Development of laminated glass technology

Technically, by optimizing the film material formula and improving the lamination process, the optical and mechanical properties of laminated glass have been significantly improved, meeting the special needs of different application scenarios

In the future, the development of laminated glass industry will pay more attention to functional and aesthetic design, such as introducing intelligent dimming and photovoltaic conversion technology, and developing intelligent laminated glass with dynamic adjustment of transmittance and self generation function.
