Product Description
Recyclable And Eco-friendly Rock Wool Boards With High Waterproof Performance
Hydrophobic rock wool board is a thermal insulation material that improves its water resistance through special processes, such as adding hydrophobic agents. It retains the core advantages of rock wool while offering enhanced moisture resistance and durability.
Hydrophobic rock wool board is a thermal insulation material that improves its water resistance through special processes, such as adding hydrophobic agents. It retains the core advantages of rock wool while offering enhanced moisture resistance and durability.
Key Features
- Excellent Hydrophobicity: Water absorption rate typically below 5% (under 3% for premium products), preventing liquid penetration even in high humidity
- Superior Fire Resistance: Non-combustible (Class A rating), produces no toxic fumes at high temperatures
- Thermal Insulation: Low thermal conductivity due to numerous closed pores between fibers
- Chemical Resistance: Resistant to acid, alkali, and environmental corrosion
- Structural Stability: Maintains shape in humid conditions without loosening or cracking
Applications
Ideal for moisture-resistant applications including:
- External wall insulation systems
- Roof insulation layers
- Underground engineering (subways, tunnels)
- Outdoor industrial pipe insulation
- High-humidity interior spaces (bathrooms, cold storage)
Waterproof Performance Comparison
| Material | Waterproof Principle | Water Absorption Rate | Applicable Environment | Limitations | Waterproof Lifespan |
|---|---|---|---|---|---|
| Hydrophobic Rock Wool Board | Hydrophobic treatment reduces water adsorption | ≤5% (≤3% for high-quality products) | High-humidity insulation scenarios | Requires combination with other waterproof layers | 15-20 years |
| Concrete | Dense structure formed by adjusting mix ratio | Impermeability grade P6-P12 | Structural waterproofing | May crack under stress | 10-30 years |
| Coating Types | Forms continuous waterproof film | Almost no water absorption | Small-area scenarios | Breathability/UV resistance issues | 10-15 years |
| Metal Materials | Non-absorbent by nature | 0% | Large venues | Joints prone to seepage | 20-50 years |
