Product Description
Our eco-friendly fireproof rock wool boards are manufactured from natural basalt and diabase rocks melted at temperatures exceeding 1500°C. These inorganic mineral boards feature Class A non-combustible properties, fundamentally eliminating ignition risks. Unlike combustible plastic insulation materials, rock wool maintains structural stability at high temperatures (melting point ≈1000°C) without emitting toxic fumes, providing critical fire protection in building applications.
Key Advantages
The fibrous, porous structure ensures low thermal conductivity for superior insulation performance while maintaining energy efficiency. Hydrophobic variants offer reliable moisture resistance with water absorption rates ≤5% (≤3% for premium grades). The material's chemical stability ensures long service life, and its non-toxic composition supports sustainable building practices.
Applications
- Building insulation for walls, ceilings, and partition walls
- Industrial furnace and kiln insulation
- Data center server room temperature control
- Transportation insulation (train compartments, bus bodies)
- Cold storage facility insulation
- Historic building renovations
Fire Resistance Performance Comparison
| Building Materials | Fire Performance Class | Fire Resistance Rating | Characteristics When Burning | Applicable Scenarios |
|---|---|---|---|---|
| Rock Wool Board | Class A1 (Non-combustible) | 1-4 hours | Does not burn, maintains structural stability | Wall insulation, fire barriers |
| Expanded Polystyrene (EPS) | Class B2 (Combustible) | 0.1-0.3 hours | Releases toxic fumes, fast fire spread | Low-rise buildings (with fire protection) |
| Polyurethane Foam (PU) | Class B3 (Flammable) | <0.1 hours | Highly flammable, releases toxic gases | Restricted non-exposed uses |
| Glass Wool Board | Class A1 (Non-combustible) | 0.5-2 hours | Stable at high temperatures | Duct insulation, partition walls |
