High Quality Factory Sale Insulating Rock Wool Board
Rock Wool Board is a high-performance, inorganic insulation material manufactured from natural volcanic rock, typically basalt or diabase, and recycled slag. The raw materials are melted at extreme temperatures (approximately 1,500°C) and then spun into fine fibers using a centrifugal process. These fibers are then bonded with a thermosetting resin and formed into rigid or semi-rigid boards.
Key Properties
Excellent Thermal Insulation
Low thermal conductivity (typically 0.035-0.045 W/m·K) helps reduce energy consumption in buildings and industrial applications.
Superior Fire Resistance
Rock wool is non-combustible (Class A1 or A2 according to European standards). It can withstand temperatures up to 1,000°C without melting, acting as an effective fire barrier.
Acoustic Performance
The fibrous structure provides excellent sound absorption, making it ideal for noise reduction in walls, ceilings, and floors.
Water Repellent but Vapor Permeable
Most rock wool boards are treated with a water-repellent agent, preventing moisture absorption while allowing water vapor to pass through, which helps avoid condensation and mold growth.
Mechanical Strength
Rigid boards offer good compressive strength, suitable for load-bearing applications like flat roofs and under concrete slabs.
Dimensional Stability
Does not expand, shrink, or warp over time, ensuring long-term performance.
Environmental Benefits
Recycled Content - Contains up to 30-40% recycled slag.
Recyclable - Rock wool can be recycled into new insulation products.
Low Embodied Energy - Compared to many other insulation materials.
Durability - Long service life (50+ years) reduces replacement waste.
