Thermal Insulation Materials Low Carbon High Performance Functional Integration

Driven by the dual carbon strategy and new regulations such as the General Code for Building Energy Efficiency and Renewable Energy Application, China's thermal insulation material industry has shifted from scale expansion to an upgrade stage centered on low-carbon, high-performance, and functional integration. Inorganic thermal insulation materials including rock wool, glass wool, and ceramic fiber blankets are rapidly transforming into full-scenario comprehensive solutions.

At the policy level, green building material certification and carbon footprint accounting have become market access thresholds. The 14th Five-Year Plan for Building Energy Efficiency and Green Building Development has further boosted the demand for low-carbon materials. On the market side, formaldehyde-free and recyclable insulation products are replacing traditional high-carbon materials. In 2025, low-carbon insulation materials accounted for more than 60% of the market, and products with over 30% recycled raw materials achieved an annual growth rate of 18%.

High performance has become the core of competition: rock wool maintains Class A1 non-combustibility, with a thermal conductivity as low as 0.036 W/(m·K) and a water repellency rate of over 99%; glass wool has a Noise Reduction Coefficient (NRC) of 0.95 and a density of only 16kg/m³, suitable for acoustic and lightweight requirements; conventional ceramic fiber blankets resist 1200℃, and special models reach 1400℃, supporting high-temperature industrial energy conservation. All three types of products have improved energy efficiency by 20%-30% and extended service life by 15-20 years.

Functional integration unlocks new potentials: integrated products featuring "thermal insulation + fire protection + sound absorption" are the first choice for public buildings in the construction sector; modular products in the industrial field improve construction efficiency, and ceramic fiber blankets are upgraded to be "high-temperature resistant + corrosion resistant"; innovative directions such as "thermal insulation + intelligent monitoring" are driving the industry to transform from material suppliers to solution service providers.

As a seasoned player in the industry, the company keeps pace with trends: in terms of low-carbon production, the recycled raw material ratio of rock wool reaches 35% and the waste glass recovery rate of glass wool hits 42%, with all series of products obtaining green certifications; in terms of high performance, we launch high-end rock wool with a thermal conductivity of 0.035 W/(m·K) and other top-tier products; in terms of integration, we create scenario-based customized solutions and serve thousands of key projects. In the future, we will focus on expanding recycled raw materials, breaking through performance indicators, and expanding functional boundaries to continuously empower green development.
