Product Description
Cost-effective Medium-density Rock Wool Boards With Overall Excellent Performance
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.
Product Characteristics
The density of rock wool board is the key indicator determining its performance and application. Medium-density rock wool boards have a density ranging from 80 to 120 kg/m³ with these properties:
- Thermal conductivity: 0.042-0.050 W/(m*K)
- Compressive strength: 80-150 kPa with good flexural resistance
- Hydrophobic rate ≥98% (when treated with hydrophobic agents)
- A1 non-combustible materials with 1-2 hours fire resistance rating
- Better structural stability at high temperatures than low-density products
Key Advantages
- Balanced combination of thermal insulation and structural strength
- Wide application scenarios with high cost performance
- Strong adaptability to dry or slightly humid environments
- Excellent construction compatibility with rendering mortar and mesh cloth
Primary Applications
- External and internal wall insulation systems in multi-storey buildings
- Non-heavy-load roof insulation (flat roofs with waterproof layers)
- Hot water pipes and industrial medium/low-temperature pipes (≤150℃)
Comparison of Rock Wool Boards by Density
| Category | Parameters | Performance | Advantages | Main Applications |
|---|---|---|---|---|
| Low-Density | 40-80 kg/m³; 0.038-0.045 W/(m*K); 30-80 kPa | Excellent insulation, low strength, Class A1 non-combustible | High insulation efficiency, low cost, lightweight | Non-load-bearing indoor insulation, sound absorption, air duct insulation |
| Medium-Density | 80-120 kg/m³; 0.042-0.050 W/(m*K); 80-150 kPa | Good insulation, moderate strength, 1-2hr fire rating | Balanced performance, wide applications, cost-effective | External wall insulation, roof insulation, pipe insulation |
| High-Density | 120-200 kg/m³; 0.048-0.055 W/(m*K); ≥150 kPa | High strength, 2-4hr fire rating, weather resistant | Structural stability, superior fire safety | Load-bearing parts, fire barriers, industrial kilns |
