Core Technical Structure:

  • Extreme Fire Endurance:As an inorganic material, its melting point exceeds 1000°C. In a fire, it produces zero smoke and no flaming droplets, significantly extending the fire endurance of the building structure and providing crucial time for evacuation.
  • Thermal Stability & Durability: Featuring an extremely low coefficient of linear expansion, the boards resist cracking or deformation caused by temperature fluctuations, ensuring a service life that matches the lifespan of the building itself.
  •  Compressive & Tensile Strength:Utilizing a specialized fiber orientation process, our products offer high perpendicular tensile strength (TR value), making them ideal for External Thermal Insulation Composite Systems (ETICS) with thin base coats.

Product Advantages:

  • Chemical Neutrality & Anti-corrosion:With a neutral or slightly alkaline pH, the material is non-corrosive to carbon steel, stainless steel, aluminum, and other metallic components, protecting building frames and fasteners.
  • Sustainability & Eco-friendly:We are committed to sustainability. Our rock wool products are 100% free of CFCs, HFCs, HCFCs, or any ozone-depleting substances and are fully recyclable at the end of their life cycle.
  • Global Adaptability: We offer customized solutions in various densities and thicknesses to suit diverse climates, ranging from the high-temperature deserts of Saudi Arabia to the high-humidity regions of India and Indonesia.
