Rock Wool Insulation Board – Fireproof Acoustic Mineral Wool for External Wall, Roof & Industrial Use – Non-Combustible & Breathable

Haoou Rock Wool is a high-density mineral wool insulation board made from natural basalt rock and recycled slag. Melted at over 1600°C and spun into fine fibers, it creates a three-dimensional interlocking structure that traps air, blocks heat, absorbs sound, and resists fire. It is the ideal choice for building envelopes, industrial insulation, and marine applications.

Why Choose Haoou Rock Wool?

• Class A1 Non-Combustible
  Withstands temperatures above 1000°C without melting or releasing toxic smoke. Acts as a fire barrier to slow flame spread. Essential for high-rise buildings, hospitals, schools, and industrial plants.

• Superior Thermal & Acoustic Performance
  Thermal conductivity as low as 0.035 W/m·K. Open fiber structure provides excellent sound absorption (NRC up to 0.95), reducing noise between rooms and from external sources.

• Breathable & Moisture Vapor Permeable
  Allows water vapor to escape, preventing condensation buildup inside wall cavities. No mold or rot – maintains healthy indoor air quality.

• High Mechanical Strength
  Compressive strength and tensile strength available in multiple densities (40–200 kg/m³). Suitable for both vertical and overhead installations.

• Hydrophobic Treatment Option
  Water-repellent grade available for outdoor applications. Does not absorb rain or humidity while remaining vapor permeable.

• Eco-Friendly & Sustainable
  Contains up to 40% recycled content. Reduces building energy consumption for decades. Inert and chemically stable – no off-gassing.

Applications:

• External thermal insulation composite system (ETICS) for facades

• Cavity wall and curtain wall insulation

• Metal roof and pitched roof insulation

• Interior partition walls and floating floors
