Our Class A1 non-combustible fireproof rock wool board is specially engineered for external wall insulation systems, meeting the highest national standard for non-combustible materials (Class A1). Made from high-quality basalt through advanced melting, fiberizing, and curing processes, it offers exceptional fire safety and performance characteristics.
| Parameter Product | FR120 | FR140 |
|---|---|---|
| Density (kg/m³) | 120 | 140 |
| Tensile Strength (kPa) | ≥7.5 / 10 | ≥10 / 15 |
| Thermal Conductivity (W/m*K, 25°C) | ≤0.038 | ≤0.040 |
| Combustibility | Class A1 non-combustible | |
| Acidity Coefficient | ≥2.0 | |
| Hydrophobic Rate (%) | ≥99.0 | |
Meets Class A1 non-combustible material standard: does not burn, contribute to fire, or propagate flames. With a melting point above 1000°C, it provides the most reliable fire barrier for buildings.
100% inorganic mineral fibers emit no toxic gases or dense smoke during a fire, buying crucial time for evacuation and maximizing life safety.
High acidity coefficient ensures resistance to corrosion, humidity, and chemical exposure—fire performance never degrades over time, providing lasting protection.
Excellent thermal stability means no shrinkage, deformation, or cracking under high temperatures, ensuring tight panel joints and effectively blocking flame penetration paths.
