Product Overview: Rock Wool Blanket & Mineral Wool Insulation Blanket

Rock wool blanket (also known as mineral wool insulation blanket, stone wool blanket, or basalt wool roll) represents a flexible, lightweight insulation material composed of fine fibers spun from molten basalt rock and blast furnace slag. Specifically, the fibers are bonded with a thermosetting resin and formed into rolls, creating a resilient and durable insulation material. Consequently, this structure delivers excellent thermal insulation, sound absorption, and fire protection performance across a wide range of industrial and building applications.

TARCO Industry produces its rock wool blanket from high-quality basalt rock and blast furnace slag, melting these raw materials at temperatures exceeding 1500°C. During production, we fiberize the molten rock using high-speed spinning wheels and apply a hydrophobic binder to create a water-repellent blanket. Ultimately, the product is formed into rolls and can be supplied with various facings including aluminum foil, wire mesh, or glass cloth to suit specific application requirements.

Key Features & Benefits of Rock Wool Blanket

Furthermore, rock wool blanket offers exceptional fire resistance with a melting point exceeding 1000°C, ensuring the highest level of fire safety in industrial and building applications. Additionally, the product achieves Euroclass A1 non-combustible fire classification, the highest possible rating, contributing no fuel to a fire. Moreover, rock wool blanket provides excellent thermal insulation with low thermal conductivity values ranging from 0.034 to 0.049 W/m·K. Consequently, the dense fiber structure delivers superior sound absorption with a noise reduction coefficient (NRC) of 0.75 to 1.05 depending on density and thickness. Therefore, the hydrophobic binder ensures water repellency greater than 98%, preventing moisture absorption and maintaining thermal performance over time. In addition, rock wool blanket is chemically inert, rot-proof, vermin-proof, and resistant to microbial growth for long service life. Furthermore, the product is asbestos-free and safe to handle, with fibers classified as IARC Group 3 (not classifiable as carcinogenic to humans). Finally, rock wool blanket can be supplied with various facings including aluminum foil, galvanized wire mesh, or stainless steel wire mesh for enhanced durability and mechanical protection.
