Chinese 2025 White Paper on The Development of The Building Thermal Insulation Material Industry

The "2025 White Paper on the Development of the Building Insulation Materials Industry" points out that building energy consumption accounts for 37% of the total social energy consumption. As the core carrier of building energy conservation, the market size of insulation materials will exceed 320 billion yuan in 2025. The industry is moving away from the extensive quantity - expansion mode and stepping into a new transformation stage centered on quality improvement.

At present, the industry is plagued by prominent pain points. In terms of performance, the 2025 inspection data from the National Building Materials Testing Center shows that 40% of rock wool boards have a thermal conductivity of no less than 0.042W/(m·K), failing to meet the relevant acceptance standards, and 30% of products only reach the B1 - level fire - resistance rating, which cannot meet the needs of high - rise buildings. The environmental protection situation is even more worrying. Due to the use of formaldehyde - containing binders, 60% of insulation materials release excessive formaldehyde, endangering human health. In addition, 80% of enterprises engage in imitative production, resulting in serious homogenization. The cycle from raw material procurement to finished product delivery takes 15 - 20 days, leading to low supply chain efficiency. Meanwhile, according to the report released by SNS Insider on December 20th, the global insulation materials market will reach 64.61 billion US dollars in 2025 and is expected to exceed 115.05 billion US dollars by 2033. The US market size will hit 24.94 billion US dollars by 2033. Global growth is driven by the implementation of carbon neutrality goals in various countries and the rising demand for green buildings.

To address these predicaments, enterprises such as Langfang Kewen have focused on technological innovation. The inorganic fiber - reinforced rock wool board developed by Langfang Kewen, which adds nano - silica particles, has a thermal conductivity reduced to 0.038W/(m·K). It adopts an environmentally friendly water - based binder to solve the formaldehyde problem, with the formaldehyde emission ≤ 0.05mg/m³. This product has been successfully applied in Beijing Daxing International Airport, reducing the terminal's winter heating energy consumption by 25%. Other enterprises have launched ultra - fine glass wool and modular integrated insulation and decoration panels to meet the needs of different high - end scenarios.

In terms of policies, the relevant plans issued by the Ministry of Industry and Information Technology have promoted the digital transformation of the industry. In the future, the industry will firmly move towards greenization, digitalization and customization. Green and formaldehyde - free materials will become the mainstream. The Internet of Things and intelligent manufacturing will shorten the delivery cycle, and personalized solutions will replace standard products. Technological R & D and high - quality services will replace low - price competition and become the core of the industry's competition pattern.
