1、 Industry Definition and Development Background

1 Core Definition

Rock wool board is an inorganic fiber board made from natural ores such as basalt and dolomite through processes such as high-temperature melting, centrifugal spinning, and cotton solidification. The density range is usually 80-200kg/m ³, the thermal conductivity coefficient is ≤ 0.040W/(m · K), and the fire rating reaches Class A (non combustible). According to the application scenario, it can be divided into building rock wool board (external wall insulation, roof insulation) and industrial rock wool board (pipeline insulation, equipment insulation).

2. Policies and Macro Environment

-Top level design: In January 2026, the Ministry of Housing and Urban Rural Development released the "14th Five Year Plan for Building Energy Efficiency and Green Building Development", which clearly requires that by 2028, new urban buildings should fully implement green building standards, and the proportion of A-level fireproof insulation materials for exterior walls should be increased to over 90%, directly benefiting the demand for asbestos board.

-Local supporting facilities: 12 provinces and cities including Beijing, Shanghai, and Jiangsu have introduced subsidy policies for ultra-low energy buildings, providing a subsidy of 50-100 yuan per square meter for projects using high-efficiency insulation materials such as rock wool boards (data source: AIMA "2026 Local Green Building Policy Compilation").

-Environmental constraints: In December 2025, the Ministry of Ecology and Environment issued the "Action Plan for the Prevention and Control of Volatile Organic Compounds (VOCs) Pollution", which restricts the use of organic insulation materials (such as polystyrene board and polyurethane) in densely populated residential areas and promotes the penetration rate of inorganic materials such as rock wool board.

3 driving factors

-Technology driven: The popularization of third-generation rock wool board production technology (such as electric furnace melting and negative pressure forming) has increased the single line production capacity from 15000 tons/year to 30000 tons/year, reducing energy consumption by 20% (CCID Consulting, 2026).

-Demand driven: In 2026, the renovation of old urban communities in China will enter a peak period, with plans to renovate 200000 residential buildings and a demand for exterior wall insulation updates exceeding 500 million square meters (Ministry of Housing and Urban Rural Development, 2026).

-Capital driven: From 2021 to 2025, there were 32 financing events in the rock wool board industry, including 4 IPO companies (Beixin Building Materials, Luyang Energy Conservation, etc.), and the market share of top companies increased to 45% (iResearch Consulting, 2026).

-Policy driven: The new version of the "Code for Fire Protection Design of Buildings" will be implemented in 2026, which specifies that A-level materials must be used for external wall insulation of public buildings, with rock wool board becoming the preferred solution.

3、 Core pain points and real-life bottlenecks (in-depth analysis)

1. Technical bottleneck

-High production energy consumption: The production of rock wool board requires high-temperature melting at 1450 ℃, with a unit product energy consumption of 800kgce/ton, which is twice that of glass wool (Tsinghua University, 2025).

-Product homogenization: The proportion of mid to low end rock wool boards (density 80-120kg/m ³) exceeds 70%, while high-end products (such as ultra-low thermal conductivity and high hydrophobicity) rely on imports (CCID Consulting, 2026).

2. Cost pressure

-Fluctuations in raw material prices: In 2026, the average price of basalt increased by 15% year-on-year, and the price of coke increased by 22%, resulting in a 12% increase in the cost of rock wool board (Beixin Building Materials, 2025 annual report).

-Rising environmental protection costs: The investment in waste gas treatment equipment (such as dust removal and desulfurization) accounts for 18% of fixed assets, which increases the burden on small and medium-sized enterprises (AIMA research, 2026).

3 Compliance Risks

-Uneven quality: In 2025, the State Administration for Market Regulation conducted spot checks and found that 15% of rock wool board products did not meet the standards for thermal conductivity and acidity, posing safety hazards (State Administration for Market Regulation, 2025).

-Certification barrier: Exporting to the European Union requires CE certification (EN 13162 standard), and only 30% of domestic enterprises have the qualifications, limiting overseas market expansion (China Council for the Promotion of International Trade, 2026).

4 Talent Shortage

-Shortage of technical workers: The production of rock wool board requires professional skills such as high-temperature operation and equipment maintenance, but the proportion of technical workers in the industry is less than 20%, and there is a serious loss of young labor force (AIMA research, 2026).

5 cognitive biases

-Insufficient market education: Some developers mistakenly believe that rock wool board has a high water absorption rate and is easy to peel off, and still tend to choose organic materials such as polystyrene board, although its fire resistance is much lower than rock wool board (Tongji University research, 2025).

6 ecological shortcomings

-Lack of recycling system: After the service life of rock wool board ends, the recycling rate is less than 5%, and a large amount of waste is buried or incinerated, resulting in resource waste (Ministry of Ecology and Environment, 2025).

After the implementation of the new version of the Building Energy Efficiency Code in 2026, the demand for rock wool board has surged, but the increase in raw material prices and environmental protection costs has compressed the profit margins of small and medium-sized enterprises. It is expected that by 2027, the industry CR10 will increase to 65%, and top companies will consolidate their advantages through scale and technology (CCID Consulting, 2026).

-Insight 2: Technological iteration is the key to breaking through homogenization

Ultra low thermal conductivity (≤ 0.030W/(m · K)), high hydrophobicity (water absorption rate ≤ 1%), and lightweight (density ≤ 100kg/m ³) have become the core indicators of high-end products. In 2026, the R&D investment of Beixin Building Materials, Luyang Energy Conservation and other enterprises will account for 5%, and the number of patents will increase by 40% year on year (China National Intellectual Property Administration, 2026).

-Insight 3: The industrial sector may become the second growth pole

The growth rate in the construction sector has slowed down (CAGR 8%), while the demand in the industrial sector (petrochemicals, electricity, new energy) has grown rapidly (CAGR 15%). By 2026, the market size of industrial rock wool board will reach 8 billion yuan, with its proportion increasing to 28% (iResearch Consulting, 2026).
