Rock Wool Blanket with Wire Mesh – Thermal Insulation Fireproof and Sound Absorption for Industrial Applications
Our Rock Wool Blanket with Wire Mesh is a high-performance insulation material manufactured from natural volcanic rock such as basalt and dolomite. The raw materials are melted at approximately 1500°C and centrifuged into fine fibers, then formed into flexible blankets through a controlled process involving pendulum laying, pleating, and curing. The blanket is then reinforced by sewing with galvanized or stainless steel mesh, and can be laminated with aluminum foil or glass cloth as required. With density options ranging from 60kg/m³ to 200kg/m³, our wired-mesh rock wool blanket delivers exceptional thermal insulation, fire prevention, moisture resistance, and acoustic performance, making it ideal for large storage tanks, boilers, large-diameter pipelines, and other demanding industrial applications.
Each blanket is produced under strict quality control protocols, ensuring consistent density, dimensional accuracy, and reliable performance. The material is hydrophobic treated (≥98% water repellence), non-combustible (Class A1), and contains no asbestos or CFCs, providing a safe, durable, and environmentally responsible insulation solution. Low-chlorine options are also available for applications requiring minimal chloride content to prevent stress corrosion cracking in stainless steel equipment.

Key Benefits
- Superior Fire Resistance - Class A1 non-combustible material with a melting point exceeding 1000°C. Provides critical fire protection for industrial equipment, fire barriers, and high-temperature applications where safety is paramount.
- Excellent Thermal Insulation - Low thermal conductivity (≤0.040 W/m*K at 25°C) ensures effective heat retention, minimizes energy loss, and significantly reduces operational costs in industrial thermal systems.
- Outstanding Acoustic Performance - Noise Reduction Coefficient (NRC) ≥0.6 effectively absorbs sound and reduces noise transmission, ideal for soundproofing in industrial plants, machinery enclosures, and ventilation systems.
- Moisture Resistant and Hydrophobic - Advanced hydrophobic treatment (≥98% water repellence) prevents water absorption, maintaining insulation performance even in humid conditions and preventing corrosion under insulation.
Primary Applications
- Industrial Insulation - Thermal insulation for large storage tanks, boilers, pipelines, HVAC systems, and industrial equipment where high-temperature resistance and energy efficiency are critical.
- Fire Protection - Fire barriers, fire-rated enclosures, structural fireproofing, and passive fire protection systems requiring Class A1 non-combustible materials.
- Acoustic Control - Sound absorption in industrial plants, machinery enclosures, ventilation systems, and other noise-intensive environments.
Frequently Asked Questions
What is the purpose of the wire mesh on this rock wool blanket?
The galvanized or stainless steel wire mesh provides structural reinforcement, preventing the blanket from sagging or deforming during installation and operation. It also makes the blanket easier to handle and install on large surfaces such as storage tanks, boilers, and large-diameter pipelines. The mesh can be sewn onto one or both sides of the blanket depending on your requirements.
What facing options are available for this product?
Our rock wool blanket can be laminated with aluminum foil, glass cloth, or other facing materials as needed. Aluminum foil provides excellent heat reflection and vapor barrier properties. Glass cloth offers good mechanical protection and chemical resistance. Please specify your requirements when ordering.
Is a low-chlorine version available?
Yes. We offer low-chlorine options for applications where minimal chloride content is required, such as insulation for stainless steel equipment where stress corrosion cracking is a concern. Please specify your chloride content requirements when inquiring.
