High-Density Rock Wool Board & Felt: Class A1 Fireproof & Industrial Thermal Insulation

Rock Wool (Mineral Wool) Board and Felt represent one of the most reliable and versatile insulation solutions in the modern industrial and construction sectors. At Hebei Woqin, our products are manufactured by melting high-purity natural basalt at temperatures exceeding 1450°C, then centrifuging it into high-strength mineral fibers. This results in a material that is not only eco-friendly but also chemically stable under extreme conditions.

Core Technical Advantages:

  • Unmatched Fire Resistance: Certified as Class A1 Non-combustible, our rock wool acts as a permanent fire barrier. It does not ignite, smoke, or release toxic gases, making it mandatory for high-rise building facades and high-risk industrial zones.
  • High-Efficiency Thermal Performance: With a thermal conductivity as low as 0.034 W/(m·K), Woqin rock wool effectively stabilizes indoor climates and minimizes heat loss in heavy-duty industrial equipment such as boilers and furnaces.
  • Acoustic Precision: The unique 3D fiber structure traps sound waves, providing excellent Sound Absorption Coefficients (NRC) for residential partitions, theaters, and mechanical rooms.
  • Environmental Resilience: Our rock wool is highly breathable yet hydrophobic (water-repellent), preventing the accumulation of moisture and ensuring the long-term structural integrity of the insulation layer.

Industrial & Architectural Applications:

  • Building Envelopes: Ideal for Exterior Insulation Finish Systems (EIFS), curtain walls, and roof insulation to meet international energy codes.
  • Power & Petrochemical: Heavy-duty blankets and boards for high-temperature pipelines, tanks, and chemical reactors.
  • Marine & Offshore: Specialized lightweight rock wool for ship interior fireproofing and acoustic dampening.

As a direct manufacturer, Hebei Woqin provides customized densities (ranging from 40kg/m³ to 200kg/m³) and thicknesses tailored to your engineering specifications. Whether you are optimizing industrial furnace efficiency or commercial building safety, our rock wool solutions offer the durability and performance required for the most demanding global projects.
