This high-performance stone-wool insulation product adopts high-quality natural basalt as the core raw material, which is melted at ultra-high temperature, centrifuged into fine fibers via four-roller centrifugal technology, and finally pressed and cured with customized environmentally friendly binder to form finished Basalt Wool Board. With a fixed density of 80kg/m³, this professional stone-wool material balances outstanding compressive mechanical properties and ultra-low thermal conductivity perfectly, making it an ideal insulation solution for building exterior walls, industrial equipment and pipeline insulation projects that require moderate mechanical strength and stable thermal insulation performance.

Product Features
Precise Density Control: The 80kg/m³ density of Basalt Wool Board is the optimal setting for stone-wool insulation materials, perfectly balancing lightweight property and structural strength. It delivers superior compression resistance and wind load resistance compared with low-density fiber stone-wool boards, while being lighter and easier to cut, transport and install than high-density stone-wool products.
Three-Dimensional Fiber Structure: The internal basalt fibers of the stone-wool board are randomly and densely interwoven, forming tiny, uniform and stable pores. This unique structure effectively suppresses convective heat transfer inside the material, achieving excellent thermal insulation effect while maintaining stable airflow resistance, ensuring long-term consistent insulation performance of Basalt Wool Board.

Product Advantages (Comparison with Similar Insulation Boards)
Comparison Items: 80kg/m³ Basalt Wool Board (Stone-wool), Ordinary 60kg/m³ Rock Wool Board, Low-Density Glass Wool Board
Compressive & Wind Resistance Superiority: High-strength stone-wool structure enables Basalt Wool Board to withstand foot traffic and slight extrusion during maintenance without deformation, with excellent wind pressure resistance optimized for high-rise building exterior walls, far outperforming ordinary rock wool and low-density glass wool boards.
Superior Acoustic & Moisture-Proof Performance: The 80kg/m³ optimized density of the stone-wool board achieves an NRC of up to 0.90 for excellent mid-to-low frequency noise absorption. Meanwhile, it features ≥99% water repellency and low water absorption, avoiding freeze-thaw damage and mildew growth for long-term stable use.
Wind Resistance: Excellent wind pressure resistance, specially optimized for high-rise building exterior wall insulation scenarios; Ordinary wind resistance, only suitable for low-rise buildings; Poor wind resistance, prone to layer peeling and damage in windy environments.
