With increasingly stringent safety regulations and building standards across various industries, the fire-resistant glass market is entering a period of sustained and steady growth.

Focusing on the domestic market, the growth momentum of fire-resistant glass is even stronger. The demand for fire-resistant glass is directly related to the enforcement of building fire protection standards. By the end of 2025, many regions in China will have issued new versions of building fire protection codes, explicitly requiring the use of fire-resistant glass in high-rise buildings, commercial complexes, transportation hubs, and other locations. From a regional market perspective, the demand for fire-resistant glass is particularly strong in East and South China due to the high density of high-end buildings and concentrated new energy projects.

Of particular note is the emerging new energy sector, which is becoming a new growth engine for fire-resistant glass demand. The demand for fire-resistant glass in scenarios such as energy storage power stations and photovoltaic inverters is rapidly increasing. For example, the Hi-MO X10 special fire-resistant module launched by LONGi Green Energy in March 2026 is equipped with fire-resistant glass that can withstand temperatures up to 1000℃ and remain uncracked for over an hour and a half in a fire. This technological breakthrough not only provides a new solution for fire safety in photovoltaic power stations but also opens up new application scenarios for fire-resistant glass.

New National Standard Leads the Way: Quality Thresholds Raised Across the Board, Industry Faces a Major Test

On October 31, 2025, GB/T 15763.1—2025 "Safety Glass for Buildings Part 1: Fire-resistant Glass" was officially released and will be implemented on August 1, 2026. Meanwhile, the new industry standard XF 97—2025, "Non-load-bearing Fire-resistant Glass Partitions," officially came into effect on May 1, 2026. The implementation of these two standards imposes stricter quality requirements on fire-resistant glass, from the product itself to the application system.

Compared to the old standard, the new national standard has achieved a systematic upgrade in several core dimensions:

The classification system is more complete. New definitions have been added for laminated fire-resistant glass, insulated fire-resistant glass, partially insulated fire-resistant glass, and heat flux; a new partially insulated fire-resistant glass (Class B) has been added, forming a complete system with the existing insulated (Class A) and non-insulated (Class C) types; the fire resistance time rating has been refined to five levels: 0.50h, 1.00h, 1.50h, 2.00h, and 3.00h.

Material selection is more diverse. A new borosilicate monolayer fire-resistant glass has been added to meet the needs of high-temperature and large-span special scenarios; a new rapid identification method for borosilicate and soda-lime silicon glass materials has been added to facilitate market supervision.

Performance requirements are more stringent. New requirements for surface stress and surface stress uniformity have been added to improve product quality control; new requirements for moisture resistance have been added, and testing methods for fire resistance, heat resistance, cold resistance, and radiation resistance have been optimized.

Focusing on core performance: Impact resistance and fragmentation testing methods have been removed, making the standard more focused on core fire-resistant performance.

The Fire Protection Product Conformity Assessment Center held a meeting in April 2026 to promote the new version of the implementation rules for fire-resistant door and window product certification and the new standard. More than 800 people attended, including representatives and certification technical personnel from manufacturers of fire-resistant glass products and non-load-bearing fire-resistant glass partitions. The meeting clearly pointed out that fire-resistant glass and non-load-bearing fire-resistant glass partitions are key components in building fire protection systems. All manufacturers must earnestly fulfill their primary responsibility for quality, thoroughly study the new national standards, industry standards, and certification implementation rules, and strictly organize production according to the standards.

Zhejiang Jingtai Glass Technology has already conducted comprehensive technical benchmarking and process upgrades in accordance with the new national standard. From raw material selection and optimization of nano-silicon fire-retardant adhesive formulation to adjustment of composite process parameters, the company has established a comprehensive quality control system for fire-resistant glass, ensuring full compliance with the new national standard on its first day of implementation.

Technological Breakthrough: Nano-Silicon Composite Fire-Resistant Glass, Redefining Industry Standards

At the forefront of fire-resistant glass technology iteration, nano-silicon composite fire-resistant glass, with its superior performance advantages, is becoming an important direction for industry upgrading.

Traditional grouting fire-resistant glass has long suffered from technical pain points such as fire-retardant liquid sedimentation and yellowing over long-term use. Nano-silicon composite fire-resistant glass, through optimization of nano-silicon material formulation and upgrade of composite processes, achieves a synergistic unity of four core advantages: high fire resistance, high heat insulation, high light transmittance, and aging resistance. Nano-silicon fire-retardant adhesive is a hard, inorganic, transparent fire-resistant crystalline substance. Each piece of glass undergoes 30 processes and 500 hours of production, exhibiting novel weather resistance, strong stability, and high quality.

Its fire-resistant principle is particularly ingenious: when a fire occurs, the glass facing the fire shatters rapidly upon exposure to high temperatures, and the fire-resistant interlayer subsequently foams and expands approximately tenfold, absorbing a large amount of the high heat generated by the flames, forming a white, opaque fire barrier—its hardness ensures fire resistance integrity, while its porous structure provides excellent thermal insulation performance.

In terms of technical specifications, nano-silicon fire-resistant glass can achieve a transparency of over 95%. Currently, the industry's nano-silicon composite fire-resistant glass covers all fire resistance rating requirements from 1 hour to 2 hours, suitable for all scenarios including office buildings, shopping malls, schools, hospitals, high-rise buildings, financial institutions, and data centers. The 45mm specification product can withstand temperatures above 1000℃, with no flame penetration and no significant temperature rise within 2 hours.

Zhejiang Jingtai Glass Technology Co., Ltd. is one of the earliest companies in China to develop nano-silicon composite fire-resistant glass. The company's nano-silicon composite fire-resistant glass is composed of two or more layers of glass sheets with one or more layers of inorganic expandable nano-silicon fire-resistant interlayer, possessing highly reliable fire resistance integrity and thermal insulation properties. The products are suitable not only for ultra-weather-resistant applications such as fire-resistant curtain walls, but also for applications requiring Class A fire-resistant glass with high transparency, colorfastness, and non-delamination, such as fire-resistant exterior windows. The company's products have passed the certification of the National Fireproof Building Materials Quality Supervision and Inspection Center, and core indicators such as fire resistance, heat insulation, and impact resistance have all met the standards.

Diversified Strategy: Simultaneous Development of Monolithic and Composite Products, Covering All Application Needs

In the field of fire-resistant glass, Zhejiang Jingtai Glass Technology has formed a product matrix with both monolithic and composite fire-resistant glass products developed in parallel.

Monolithic cesium potassium fire-resistant glass belongs to Class C non-insulating fire-resistant glass and adopts a high-temperature ion exchange chemical treatment process. Under the impact of flames reaching up to 1000℃, monolithic cesium potassium fire-resistant glass can remain unshaken for 84 to 183 minutes. Its strength is 6 to 12 times that of float glass of the same thickness and 1.5 to 3 times that of tempered glass. The products can be further processed into laminated safety glass, insulated glass, coated glass, and point-supported curtain wall glass, widely used in curtain walls, exterior windows, and other applications.

Composite heat-insulating fire-resistant glass belongs to Class A heat-insulating fire-resistant glass. It is made of two or more layers of glass with a transparent fire-retardant adhesive injected between them. When a fire occurs, the special transparent chemical substance in the interlayer absorbs a large amount of heat from the flames and expands, forming a barrier layer with extremely low thermal conductivity. The fire-retardant adhesive in this product is a non-combustible material, effectively preventing the spread of fire, while also possessing excellent heat insulation, thermal insulation, and energy-saving characteristics.

The company has passed the national mandatory product certification "CCC" and the EU CE certification, and its production qualifications and product quality have been recognized by authoritative domestic and international institutions. In particular, the monolithic cesium potassium fire-resistant glass and composite heat-insulating fire-resistant glass product lines have both passed the fire protection product certification of the Tianjin Fire Research Institute of the Ministry of Emergency Management.

Application Expansion: From Construction to New Energy, the Applications of Fire-Resistant Glass Continue to Expand
The application boundaries of fire-resistant glass are constantly expanding. Traditionally, fire-resistant glass has been primarily used in high-rise building curtain walls, fire compartments in commercial complexes, and transportation hubs. Entering 2026, with the rapid development of the new energy industry, the application of fire-resistant glass in emerging scenarios such as photovoltaic power plants and energy storage facilities is accelerating.

LONGi Green Energy launched its Hi-MO X10 special fire-resistant module in March 2026, equipped with fire-resistant glass that can withstand temperatures up to 1000℃. Designed to address fire hazards in photovoltaic power plants, this module enhances safety through two lines of defense: preventing ignition and preventing fire spread. The flame-retardant film and high-temperature fire-resistant glass can withstand 1000℃ flames for 1.5 hours without shattering. This technological breakthrough indicates that fire-resistant glass is rapidly expanding from the field of building fire protection to the field of new energy safety.

Meanwhile, significant breakthroughs have also been achieved in marine fire-resistant glass partition systems. In early 2026, the B15 fire-resistant glass partition, jointly developed by domestic enterprises, completed fire resistance testing at the Shanghai Far East Fire Testing Center. It significantly surpassed existing international standards in key indicators such as fire resistance integrity, thermal insulation, and structural stability. The product is currently applying for MED certification, signifying that Chinese-made fire-resistant glass products have gained the trust of world-renowned authorities in the international high-end specialty glass market.

Furthermore, the new industry standard XF 97—2025, "Non-load-bearing Fire-resistant Glass Partitions," officially came into effect on May 1, 2026. Beijing has supplemented the standard with design requirements for insulated fire-resistant glass (Class A) and non-insulated fire-resistant glass (Class C), proposed design requirements for automatic sprinkler systems made of fire-resistant glass, and refined the testing requirements for fire-resistant glass frame systems. These policy signals indicate that the application standards for fire-resistant glass are extending from the product level to the system integration level, pointing the way for the professional and refined development of the fire-resistant glass industry.

Zhejiang Jingtai Glass Technology Co., Ltd. will closely follow the expanding application scenarios of fire-resistant glass, continuously enrich its product line, and actively meet the fire-resistant glass needs of emerging fields such as photovoltaics, energy storage, and shipbuilding, providing safer and more reliable products to serve a wider range of fire safety scenarios.
