High-Quality Rock Wool Board
1. Product Introduction:
Rock wool board is manufactured from natural minerals such as basalt and diabase, melted at temperatures above 1450°C, and processed using advanced international centrifugal technology to form man-made inorganic fibers. Through a pendulum layering process, the fibers are arranged in a three-dimensional, interlocking structure, resulting in a lightweight yet robust board. It is widely applicable in building exterior insulation, industrial equipment and pipeline insulation, ship cabin fireproofing, and other fields, making it an ideal material for energy efficiency, environmental protection, and safety.
2. Features
Class A1 Fire Rating – Meets the highest fire resistance standard; does not ignite and effectively slows the spread of flames.
High-Efficiency Thermal Insulation – Low thermal conductivity of 0.035–0.044 W/(m·K), offering excellent insulation performance.
Sound Absorption and Noise Reduction – Porous fiber structure effectively absorbs sound waves, significantly reducing environmental noise.
Water Repellency and Moisture Resistance – Water repellency rate ≥99%, maintaining stable thermal insulation performance over the long term.
Eco-Friendly and Durable – Made from inorganic materials, resistant to mold and corrosion, with a long service life.
3. Applications
Building Exterior Insulation – Used in various external wall insulation systems to meet energy-saving design requirements.
Industrial Equipment Insulation – Thermal insulation for pipelines, storage tanks, boilers, and other industrial equipment.
Fireproof Barriers – Fire sealing for building fire compartments, cable penetrations, and other critical areas.
Shipbuilding – Thermal insulation and fireproofing for ship cabins, meeting maritime safety standards.
HVAC and Ventilation Systems – Insulation for air ducts and noise reduction treatment for equipment rooms.

FAQ
Q1: Does rock wool board absorb water? How is its moisture resistance?
A1: With a water repellency rate of ≥99%, it offers excellent moisture resistance and is not easily affected by dampness during long-term use.
Q2: What should be noted during the installation of rock wool board?
A2: Ensure the substrate is flat and dry; use specialized adhesives for fixation; seal joints tightly; and ensure proper ventilation and protective measures during construction.
Q3: How to distinguish the quality of rock wool board?
A3:Check the uniformity of density.
Measure thermal conductivity and water repellency rate.
Review product test reports (fire resistance, environmental certifications).
Observe whether the fibers are fine and free of impurities.
Q4: Do you provide professional installation services?
A4: We provide detailed technical guidance, installation recommendations, and recommendations for matching fixings as standard. For project-specific needs, we can also negotiate to offer professional on-site installation or construction supervision services to ensure optimal results.
Q5: Can you provide relevant quality and safety certification documents?
A5: Absolutely. We maintain a complete set of qualification documents, including third-party material test reports, MSDS (Material Safety Data Sheet), EUCEB certification (safety labeling), and RoHS compliance statements, all readily available for your project review or acceptance.
