Rock Wool Blanket with Wire Mesh

Rock wool blanket with wire mesh is a high-performance thermal and fire insulation material designed for industrial, commercial, and marine applications. It combines a flexible mineral wool insulation core with reinforced galvanized steel wire mesh, ensuring mechanical strength, dimensional stability, and long-term reliability under demanding conditions.

Product Structure & Materials

• Insulation core: High-quality mineral (rock) wool fibers
• Reinforcement: Galvanized steel wire mesh (standard)
• Optional: Stainless steel wire mesh for corrosive or marine environments

The galvanized wire mesh enhances tensile strength and prevents sagging or deformation, making the blanket suitable for vertical installations, large-diameter pipes, and high-vibration environments.

Thermal & Fire Performance

• Low thermal conductivity for effective heat retention and energy efficiency
• Continuous operating temperature up to approximately 650°C
• Non-combustible material, classified as A1 fire-rated
• No flame spread, no toxic smoke generation

These properties make rock wool blanket with wire mesh a reliable solution for passive fire protection and high-temperature insulation systems.

Mechanical Strength & Acoustic Benefits

Compared with standard rock wool blankets, the wire mesh reinforced version offers improved mechanical stability and installation safety. It maintains its shape over time and resists tearing during handling and fixing.

In addition to thermal insulation, the dense fiber structure provides effective sound absorption, helping reduce equipment and airflow noise in industrial and HVAC systems.

Typical Applications

• Industrial pipelines, valves, and flanges
• Boilers, furnaces, and heat exchangers
• HVAC ducts and exhaust systems
• Power plants and petrochemical facilities
• Marine engine rooms and shipbuilding projects
• Passive fire protection systems

Installation Recommendations

For optimal performance and long service life, rock wool blanket with wire mesh should be fixed using steel wires, metal bands, or insulation pins. Ensure tight contact with the substrate to avoid thermal bridges.

For outdoor or marine environments, an additional protective cladding such as aluminum foil, metal jacketing, or weatherproof covering is recommended.

Quality, Compliance & Reliability

High-quality rock wool blanket with wire mesh typically complies with international standards such as EN 14303 and EN 13501-1. Reliable manufacturers provide full technical documentation, test reports, and consistent quality control to ensure safe and compliant use in critical applications.

Choosing the right specification and working with experienced suppliers helps ensure long-term thermal efficiency, fire safety, and project reliability.
