Why Are Rock Wool Sandwich Boards Fireproof?
The fire resistance of rock wool sandwich panels stems primarily from the rock wool insulation used in their construction. Rock wool sandwich panels offer the following excellent fire-resistant properties:
High Melting Point: Made from natural volcanic rock, rock wool has a melting point exceeding 1000°C. Rock wool is a Class A non-combustible material and will not burn or produce toxic fumes in the event of a fire, providing reliable fire protection for buildings.
| Property | Typical Range | Unit | Performance Rating |
|---|---|---|---|
| Thermal Conductivity | 0.035 - 0.048 | W/(m·K) | Excellent |
| Density | 80 - 200 | kg/m³ | Medium |
| Compressive Strength | 40 - 80 | kPa | Good |
| Service Temperature | -200 to 650 | °C | Excellent |
High Density: Rock wool insulation maintains a consistent density of 100-120 kg/m³, restricting air flow and thus inhibiting the spread of flames.
Excellent Thermal Conductivity: Rock wool typically has a thermal conductivity between 0.035-0.048 W/(m·K), effectively preventing heat transfer and significantly improving a building's energy efficiency.
As a high-quality thermal insulation material, rock wool has become an indispensable material in modern construction and industry due to its excellent fire resistance, excellent thermal insulation effect, good sound absorption and sound insulation, and environmental safety characteristics.
