What Is Rock Wool Wired Blanket?
Rock wool wired blanket is a flexible rock wool mat faced with galvanised or stainless-steel wire mesh, giving it the mechanical retention needed for vertical surfaces, high-velocity ducts and equipment that sees vibration or airflow erosion.
Key Technical Specifications
| Property | Value |
|---|---|
| Maximum service temperature | up to 650°C (continuous) |
| Density | 100–140 kg/m³ |
| Thermal conductivity | 0.036–0.042 W/(m·K) at 25°C mean |
| Standard thickness | 25–100 mm |
| Standard dimensions | rolls 600 / 1200 mm wide × up to 5000 mm long |
| Fire classification | A1 (non-combustible, EN 13501-1 / Euroclass A1) |
| Composition | basaltic rock melted above 1500°C and spun into mineral fibres; organic binder 2–5% by weight |
| Standards | EN 13162, ASTM C612 (Type IV, up to 650°C) |
Properties & Advantages
- Wire-mesh facing holds the blanket on vertical and overhead surfaces
- Resists vibration, airflow erosion and self-weight sag
- A1 non-combustible with low heat storage
- Conforms to complex geometries and flanged shapes
- Quick to install with tying wire or pins
Typical Applications
- Boiler and furnace casings
- Duct, stack and flue insulation
- Vessel and turbine outer insulation
- Offshore and marine high-velocity systems
Installation & Handling
Wrap the blanket over the surface and secure with the integrated wire mesh using tying wire, bands or stud welding pins. Overlap joints by one mesh cell and weatherproof exposed outdoor runs with metal jacketing.

Frequently asked
What temperature can rock wool insulation withstand? +
Rock wool insulation can withstand temperatures up to 650 °C for standard grades. It is classified as a non-combustible material (Euroclass A1, ASTM E84 Class A), making it ideal for structural fire protection, industrial pipe insulation, and building envelope applications.
Does rock wool absorb water? +
No. Our rock wool products feature hydrophobic treatment with water repellency exceeding 98%. Unlike some insulation materials, rock wool maintains its thermal performance even in high-humidity environments. This makes it particularly suitable for outdoor pipework and marine applications.
Is rock wool environmentally friendly? +
Yes. Rock wool is manufactured from volcanic basalt rock — an abundant natural resource. It contains up to 75% recycled content, is fully recyclable at end of life, and contributes to building energy efficiency by reducing heat loss. It is RoHS and REACH compliant.
What density of rock wool insulation should I use? +
The optimal density depends on your application: 60–80 kg/m³ for general thermal insulation of tanks and vessels, 80–120 kg/m³ for pipe insulation and HVAC ductwork, 100–150 kg/m³ for load-bearing or structural applications, and 150+ kg/m³ for high-compression industrial flooring and sandwich panels.
