Insulating large-diameter industrial pipes, boilers, furnaces, and cylindrical tanks in plants operating with steam or hot fluids, where rigid panels do not conform to curved surfaces and require auditable fireproof energy loss control, demands a rock wool roll with stitched galvanized wire mesh that provides structural flexibility and a fastening platform. This rock wool wired mat—also called a wired mat or stitched industrial blanket—is manufactured by MOLTEXO with a density of 100 kg/m³, a thickness of 50 mm, a roll width of 0.6 m and length of 5 m, with galvanized wire mesh on one side, designed for industrial plant insulation, maintenance, and energy efficiency projects.

Key Benefits

High-temperature resistance: The material withstands typical industrial thermal ranges (steam, hot fluids) while maintaining structural integrity and insulating capacity in continuous operation for years.
Galvanized mesh stitched on one side: Provides structural support, facilitates mechanical fastening with soft wire or hooks, and allows wrapping cylindrical surfaces (pipes, boilers, tanks) without the wool detaching or losing its stated thickness.
Non-combustible material does not spread flames: Fire reaction class A1 with a melting point above 1000°C, a critical condition for industrial areas with fire risk where insulation must contain flames rather than spread them.
Flexibility for curved surfaces: The roll format adapts to large-diameter pipes, cylindrical tanks, and non-rectangular geometries, a differentiating condition compared to rigid panels which only apply to flat surfaces.
Chemical stability against metals: Chemically inert material that is not corrosive to steel, aluminum, or other metals in contact, a condition for use in plants where contact corrosion between insulation and metal piping is a critical problem.

Typical Applications and Uses

Insulation of large-diameter industrial pipes and cylindrical ventilation ducts.
Boilers, furnaces, steam generators, and thermal equipment with curved surfaces or complex geometries.
Storage tanks, cylindrical vessels, and industrial chimneys requiring continuous thermal insulation.
Acoustic insulation in machine rooms, pump rooms, and industrial areas with noise from rotating equipment.

Quality and Durability

An economical wired rock wool roll fails in two ways: the actual density is lower than declared (reducing insulating capacity and thermal resistance), and the mesh is made of low-quality galvanized wire that rusts quickly in Caribbean climates (which breaks and leaves the wool without structural support in a few years). MOLTEXO works with verifiable 100 kg/m³ density and controlled galvanized mesh, which distinguishes a professional industrial wired mat from a generic blanket that fails in continuous operation.

Also known as: Technical: wired mat, rock wool wired mat, rock wool blanket, stitched metallic mesh blanket, industrial wired blanket. In DR and Caribbean: manta de lana de roca, manta armada, manta de lana mineral, manta industrial mallada. In other countries: wired mat (USA), wire mesh blanket (USA), rock wool blanket (USA), manta de lana de roca (LATAM), manta de roche armada (FR), manta mineral (LATAM, ES).
