Loose Rock Wool Insulation - High-Quality China Suppliers & Factory for Thermal, Acoustic, and Fireproof Applications

ABM® Loose Rock Wool (IGW) is a premium loose-fill insulation product crafted from high-quality rock wool fibers. This versatile material is renowned for its outstanding thermal insulation, cold retention, and sound absorption capabilities. It can be customized in terms of filling density and thickness to meet the specific needs of various applications. Our loose rock wool is ideal for use in irregular or confined spaces, providing exceptional thermal insulation, fireproof spray coatings for steel structures and tunnels, as well as acoustic ceiling panel manufacturing. Additionally, it is suitable for cold-box air separation equipment insulation. As a leading China supplier and factory, we also offer water-repellent and low-chlorine versions tailored to customer specifications, ensuring optimal performance for all insulation needs

    Absolute Safety Guardian

    Fire Resistance

    ABM® Rock Wool is made from natural rock and is a Class A non-combustible material. With a melting point above 1000°C, it effectively slows down fire spread. In case of fire, it does not release toxic gases or molten droplets. Its excellent high-temperature performance and low thermal conductivity under extreme heat provide critical time to save lives and reduce property damage.

    Water Repellency

    ABM® ensures that industrial insulation layers remain dry in humid environments, maintaining stable thermal conductivity, preventing energy loss and metal corrosion, and significantly enhancing system durability and energy efficiency.

    Eco-Friendly Core

    Safety & Environmental Friendliness

    ABM® Rock Wool is asbestos-free. The International Agency for Research on Cancer (IARC) classifies rock wool products as Group C – not carcinogenic. Water extracts are neutral to mildly alkaline, causing no harm or corrosion to materials in contact. Free of CFCs, HCFCs, and HFCs.

    Product Advantages

    Sound Absorption

    ABM® Rock Wool’s fibrous structure forms a highly porous interconnected network, ensuring excellent acoustic absorption and noise reduction. It significantly minimizes sound reflection and transmission, creating a disturbance-free environment for work and living.

    Solid Structural Support

    Weather Resistance

    ABM® Rock Wool is resistant to freeze-thaw cycles and UV exposure. It does not expand or contract with seasonal temperature variations and can perform reliably under extreme climates without being affected by other materials.

    Efficient Energy-Saving Companion

    Energy Saving

    The energy saved during ABM® Rock Wool’s use exceeds the energy consumed in its production, transportation, and recycling by over 100 times.

    Dense and Structurally Stable

    Ease of Installation

    ABM® Loose Fill Wool can be applied by spraying or manual filling, greatly improving installation efficiency in complex conditions and effectively reducing labor costs.

    High-Quality Fibers

    Low Chlorine

    ABM® Low-Chlorine Rock Wool is chemically stable, resistant to degradation from chloride migration, and ensures that insulation systems maintain a consistently low thermal conductivity throughout their service life. Its durability matches that of the equipment, avoiding frequent replacement and maintenance costs.

    Selected Raw Materials

    Outstanding Filling Adaptability

    With excellent flowability, granular form easily fills irregular cavities and complex structures, achieving seamless insulation without dead zones.
