What's the Advantages and Applications of Rock Wool Panels' Fire Resistance in Building Safety?
Rock wool panels belong to Class A non-combustible materials. The main component, basalt, has a melting point of over 1500℃, and the fibrous structure formed after high-temperature melting is inherently non-combustible. In the event of a fire, unlike organic insulation materials (such as polystyrene boards and polyurethane boards), they do not burn, drip, or release toxic and harmful gases. This effectively prevents the spread of flames between building components, buying valuable time for personnel evacuation and fire fighting. This characteristic fundamentally reduces the risk of fire expansion caused by ignition of insulation materials in buildings, and is a core advantage in ensuring the safety of the main building structure.
The stability of the building structure during a fire is directly related to the safety of life and property, and rock wool panels have extremely strong high-temperature stability. In a sustained high-temperature environment (usually able to withstand temperatures above 600℃), their physical form and mechanical properties change minimally, without softening, shrinking, or collapsing. When used as insulation layers for walls, roofs, and other structures, even if intense combustion occurs externally, rock wool panels can still maintain structural integrity, assist in supporting the main building, delay the instability time of floors, walls, and other components, and avoid secondary disasters caused by premature building collapse.
Rock wool panels have extremely low thermal conductivity, which not only meets the requirements of building thermal insulation and energy conservation but also plays a role as a "thermal insulation barrier" in fires. It can effectively block the transfer of high temperature generated by flames to the interior of the building, reducing damage to structural materials such as steel bars and concrete inside the walls—preventing steel bars from softening due to high temperature and reducing structural strength, while also lowering the probability of indoor items being ignited by high temperature, achieving dual safety protection of "thermal insulation" and "fire resistance".
| 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 |
