Rock wool board has multi-functional advantages, including Class A1 fire rating (EN 13501-1), outstanding moisture resistance (>98% hydrophobic properties), and noise reduction capabilities (NRC up to 0.90). Unlike organic insulation materials, rock wool panels are completely non-combustible, eliminating fire risks in high-temperature environments such as power plants, refineries, and commercial buildings. Their environmentally friendly composition (containing 30-40% recycled content) and full recyclability align with global sustainability initiatives like LEED certification. Additionally, the boards' resistance to mold, pests, and corrosion ensures long-term performance in harsh conditions, delivering 20-30% better energy efficiency and 3-5x longer service life than conventional insulation products.

Product Advantages
Rock wool board offers several key features that make it a preferred choice for insulation.
It has excellent thermal insulation properties, reducing heat loss in winter and heat gain in summer. Its fire resistance is outstanding, as it can withstand high temperatures without melting or releasing toxic fumes.
The board also provides superior sound absorption, reducing noise transmission between rooms and from external sources. It is highly resistant to moisture and water absorption, preventing mold growth and maintaining its insulating properties even in humid conditions.
rock wool panel is environmentally friendly, made from natural materials and fully recyclable at the end of its life cycle.
Product technology:
The manufacturing process of rock wool board involves several steps. First, high-quality basalt and other minerals are melted at temperatures above 1450°C.
The molten material is then centrifuged at high speed to form fine fibers. These fibers are sprayed with a binder, dustproof oil, and water repellent, and then compressed into rigid boards.
The boards are then cured to enhance their stability and durability. This process ensures that the rockwool mineral board meets high standards of quality and performance
