Durable And Flexible Rock Wool Boards With Multiple Advantages
Rock wool boards are produced using natural minerals like basalt as raw materials. The rocks are melted at high temperatures, then spun into fibers via centrifugal force. The density of rock wool board is the key indicator determining its performance and application. Products with different densities show significant differences in strength, insulation properties, and cost. Here are some excellent advantages of Rock wool boards.
Excellent Thermal Insulation Performance
Rock wool boards feature a low thermal conductivity (≤0.044 W/(m·K) at room temperature for industrial-grade products with a density of 100–150 kg/m³), which effectively inhibits heat transfer. In industrial settings, this minimizes heat loss from high-temperature equipment (e.g., boilers, steam pipelines, reactors), improving thermal efficiency by 2–5% and reducing energy consumption. In construction, it blocks heat exchange between indoor and outdoor spaces, lowering heating and cooling costs for buildings and supporting energy-saving goals.
Superior High-Temperature Resistance & Fire Safety
With outstanding high-temperature stability, standard rock wool sustains long-term use at 300–600°C, while basalt-based variants can withstand up to 800°C without softening or decomposing. Classified as Class A non-combustible material, it does not burn, emit smoke, or release toxic gases when exposed to fire, making it ideal for fire-critical scenarios such as chemical plants, power stations, and building fire partitions.
Strong Chemical Stability & Durability
Resistant to acids and alkalis, rock wool boards are inert to common industrial media like heat transfer oil, steam, and general chemical raw materials. This resistance prevents corrosion-induced degradation, ensuring long-term performance in harsh environments (e.g., corrosive chemical pipelines, humid outdoor settings). Its inherent structural stability also avoids premature aging, extending the service life of insulation systems.
Good Mechanical Strength
Industrial-grade rock wool boards exhibit reliable mechanical properties, with compressive strength ≥40 kPa and flexural strength ≥15 kPa (at 120 kg/m³ density). This enables them to resist deformation, displacement, or damage during transportation, installation, and equipment operation (e.g., vibration from pumps or fans), maintaining insulation integrity in dynamic working conditions.
Low Hygroscopicity
After moisture-proof treatment, rock wool boards have a volume water absorption rate ≤5%. This prevents performance degradation caused by moisture absorption (which can double thermal conductivity) in humid environments such as underground pipelines, outdoor storage tanks, or coastal buildings, ensuring consistent insulation efficacy.
Sound Insulation & Noise Reduction
With a porous fiber structure, rock wool boards provide effective airborne sound insulation (≥30 dB for 50 mm thickness). They reduce noise transmission from high-noise equipment (e.g., industrial fans, compressors) and mitigate environmental noise (e.g., traffic, neighborhood sounds) in buildings, enhancing operational safety and living comfort.
Cost-Effectiveness & Environmental Friendliness
Compared to high-end insulation materials like ceramic fiber, rock wool offers a favorable balance of performance and cost. Made from recycled industrial by-products (e.g., blast furnace slag) in many cases, it supports circular economy principles. Additionally, its long service life reduces maintenance and replacement costs, delivering long-term economic benefits.
