Our hydrophobic rock wool combines the inherent benefits of rock wool with superior water repellency and vapor permeability. Made from high-quality basalt and treated with advanced hydrophobic technology, it achieves a hydrophobicity rate close to 100%, while retaining the natural microporous structure of rock wool fibers to allow moisture diffusion and wall breathability.
Ideal for high-rise buildings, curtain wall systems, steel structures, and humid climate zones, it enhances wall durability and indoor comfort without compromising fire safety.
Applications
Applicable to various public buildings requiring high indoor humidity control, including residences, offices, schools, and hospitals, as well as exterior wall insulation projects in humid regions.

Key Features & Advantages
Superior Water Repellency: Advanced hydrophobic treatment gives the board strong water-resistant properties, both on the surface and internally, preventing rainwater intrusion and insulation degradation.
Excellent Breathability for Moisture Regulation: The natural microporous structure of rock wool fibers allows water vapor to diffuse freely, transferring moisture from the substrate to the outside, reducing condensation and mold risks while improving indoor comfort.
Long-Lasting Thermal Performance: The combination of water repellency and breathability ensures that the air trapped within the fibers remains stable over time, preserving thermal conductivity and ensuring consistent energy efficiency.
Class A Fire Safety: 100% inorganic material with a melting point above 1000°C: non-combustible, no toxic fumes, and no molten droplets—effectively blocks fire spread and enhances building safety.
