Fireproof Rock Wool Board China Factory Leading Thermal Insulation Suppliers
Premium fireproof rock wool boards from a leading China factory. Our suppliers provide A1 grade basalt wool with 1200C heat resistance, superior sound absorption, and hydrophobic properties for industrial thermal insulation.
Our High-Performance Fireproof Rock Wool Board is a premium insulation solution engineered from high-purity natural mineral basalt wool. Designed for extreme environments, it provides an exceptional non-combustible A1 fire resistance rating capable of withstanding temperatures up to 1200°C, ensuring maximum safety by effectively blocking flame spread and reducing fire hazards in critical infrastructure.
Combining superior thermal efficiency with advanced acoustic properties, this versatile board features a low thermal conductivity (≤0.040W/(m·K)) for significant energy savings and a porous fiber structure that achieves a sound absorption coefficient of ≥0.7. With specialized hydrophobic treatment and rigorous ISO 9001 certification, our rock wool boards offer a durable, eco-friendly, and high-strength barrier against heat, noise, and moisture.
