Market space continues to expand, and laminated glass is entering a golden age of development. Laminated glass is a composite glass product made by bonding two or more panes of glass together under high temperature and pressure with one or more layers of organic polymer interlayer. This unique interlayer structure endows laminated glass with superior safety—when subjected to external force, the interlayer firmly bonds glass fragments together, preventing them from flying and causing injury; simultaneously, interlayers such as PVB effectively absorb sound waves and block ultraviolet rays, demonstrating outstanding performance in noise reduction and sun protection. According to research statistics from Hengzhou Chengsi, the global market size of laminated architectural glass was approximately RMB 39.96 billion in 2025 and is projected to reach nearly RMB 52.63 billion by 2032, with a six-year compound annual growth rate of 4.0%. Furthermore, the global market size of decorative laminated glass has reached USD 3011 million, with an annual growth rate of 5.5%. Driven by multiple demands such as new energy, smart transportation, and green building, the Chinese laminated glass industry is showing strong growth momentum.

From the perspective of the domestic market, the continued release of diverse demands such as fire safety, sound insulation and noise reduction, and energy conservation and environmental protection provides a broad application space for laminated glass. With the continuous increase in urbanization rate and the acceleration of existing building renovation, the penetration rate of laminated glass in scenarios such as commercial complexes, high-end residences, and public transportation hubs is steadily increasing. Industry forecasts predict that by 2032, China's laminated glass market will further expand, becoming a significant contributor to global market growth.

A new national standard is about to be implemented, raising quality standards across the board. On October 31, 2025, GB/T 15763.3—2025, "Safety Glass for Building - Part 3: Laminated Glass," was officially released and will be implemented on August 1, 2026. This standard, jointly issued by the State Administration for Market Regulation and the Standardization Administration of China, and managed by the China Building Materials Federation, specifies the classification, requirements, and test methods for laminated glass for building applications, applicable to the design, production, and delivery of laminated glass for building applications. Simultaneously, GB/T 15763.2—2025, "Safety Glass for Building - Part 2: Tempered Glass," and GB/T 15763.4—2025, "Safety Glass for Building - Part 4: Homogeneous Tempered Glass," were also released, forming a more comprehensive standard system for safety glass for building applications.

The implementation of the new national standard means a significant increase in the industry's entry threshold for laminated glass, with stricter requirements for product consistency. Only companies with advanced production line capabilities and rigorous quality control systems can meet the new standard's requirements. Zhejiang Jingtai Glass Technology has already upgraded its processes and optimized its products in advance to comply with the new standard, ensuring full compliance on the first day of its implementation and providing customers with compliant, safe, and reliable laminated glass products.

Interlayer Technology Iteration: A New Leap from PVB to SGP The key to laminated glass lies in the interlayer—the core material that connects two or more panes of glass and imparts their composite properties. Currently, laminated glass interlayers mainly include two types: PVB and SGP, each with its own advantages to meet the needs of different application scenarios.

PVB (polyvinyl butyral) laminated glass is currently the most widely used type of laminated glass, and its core advantages are reflected in multiple dimensions. In terms of safety, when the glass breaks due to external impact, the hydroxyl groups of the PVB film chemically bond with the oxygen atoms on the glass surface, forming stable intermolecular forces that firmly hold the fragments together, preventing them from flying and causing injury. This meets the safety requirements of curtain walls for "fall prevention and fragmentation prevention." Regarding sound insulation, PVB film has excellent sound wave damping capabilities. Actual measurement data shows that curtain walls using PVB laminated glass can reduce noise by 25 to 35 decibels, superior to ordinary insulated glass. In terms of energy saving and heat insulation, through the introduction of nano-insulating media, PVB film can block 95% to 99% of infrared radiation. Buildings using PVB laminated glass can reduce cooling energy consumption by 15% to 20%. Regarding UV protection, PVB film can absorb more than 99% of ultraviolet rays, effectively protecting furniture and textiles inside the curtain wall from fading and aging. Zhejiang Jingtai Glass Technology has mastered mature PVB laminated glass production technology, and its products are widely used in curtain walls, doors and windows, awnings, sunrooms, and other applications.

Meanwhile, SGP (ionomer cemented glass) is emerging as a new generation of laminated glass technology, becoming a new choice for high-end applications. SGP is a polymer material bonded by ionomers, significantly enhancing its adhesion to glass. Its puncture resistance is 5 times that of PVB, its tear strength is 5 times that of PVB, and its hardness is 100 times that of traditional PVB. SGP laminated glass not only provides ultimate safety protection, effectively resisting hurricanes, earthquakes, bullets, and explosions, but also brings revolutionary application possibilities—its superior mechanical properties make the glass itself a key component of load-bearing and structural integrity, capable of supporting larger, lighter, and more innovative architectural designs, opening a new path for the integration of modern architectural aesthetics and safety. SGP film has been widely used in architectural glass, curtain walls, photovoltaics, transportation, and automotive fields, becoming one of the safest glass varieties currently available. Industry analysis shows that PVB film has better ductility, is easier to bond with glass at room temperature, and is lower in cost, making it suitable for conventional curtain wall scenarios; while SGP is mostly used in special scenarios with extremely high strength requirements, such as super high-rise buildings and large-span curtain walls. Zhejiang Jingtai Glass Technology Co., Ltd. closely follows the development trends of materials technology and actively invests in the research and development and production of high-value-added laminated glass products, continuously enriching its laminated glass product portfolio.

Automotive Solar Sunroofs: A New Blue Ocean for Laminated Glass

In 2026, the large-scale mass production of solar sunroofs for new energy vehicles will be a major breakthrough in the application of laminated glass. These sunroofs utilize a laminated structure, embedding high-efficiency solar cell modules between two panes of glass. Under sufficient sunlight, they can generate three to five kilowatt-hours of electricity per day; taking a common SUV as an example, it generates approximately 2.5 kilowatt-hours per day in summer, providing an additional range of approximately 900 kilometers per year.

Currently, industry leaders such as Fuyao Glass have developed solar sunroof glass with integrated solar cell modules and have the capacity for mass production. Solar sunroofs are not limited to extending range—for camping enthusiasts, vehicles equipped with this system can serve as outdoor power hubs, continuously powering in-car refrigerators, lighting equipment, and electronic devices when parked, achieving multi-purpose functionality. BYD has already pioneered the use of photovoltaic roof technology in its Han Tang model, generating 2 to 5 kilowatt-hours of electricity after 8 hours of exposure to sunlight.
