According to data from *Development of China's Architectural Decoration Materials Industry (2026)*, mineral wool boards account for 41.3% of ceiling materials used in public educational buildings nationwide, with a stable compound annual growth rate of 9.2%. Mineral wool boards typically achieve a Class A non-combustible rating in compliance with GB 8624-2012 (*Classification for burning behavior of building materials and products*), which is equivalent to the international A1/Class A standard. Fire safety testing protocols include non-combustibility tests (ISO 1182, GB/T 5464), combustion performance tests (GB 8624, EN 13501-1), smoke density tests (ASTM E662, GB/T 8627), and flame spread index tests (ASTM E84, GB/T 20285).
Leading manufacturers generally employ a six-stage production process-raw material melting, fiber formation, slag removal via washing, drying and curing, precision cutting, and surface treatment-leveraging intelligent technologies to enhance product precision and yield rates. Demand for mineral wool boards is characterized by requirements for high safety, low noise, high durability, and ease of maintenance; regarding environmental sustainability, the industry focuses on improving durability, optimizing manufacturing processes, and refining recycling systems. For regions characterized by extreme cold and low humidity (such as Qinghai), key performance indicators requiring verification include freeze-thaw cycle resistance (recommended ≥25 cycles), low-temperature flexibility (no cracking at -20°C), and thermal conductivity (≤0.040 W/m·K).
