Eco-friendly Fireproof Rock Wool Boards With Excellent Performance In Various Fields
The fire resistance of rock wool boards derives from their raw material properties and high-temperature stability. They are manufactured from natural rocks such as basalt and diabase, which are melted at temperatures exceeding 1500°C. As inorganic minerals, these rocks feature Class A non-combustible properties, fundamentally precluding the possibility of being ignited or supporting combustion. In contrast to Class B plastic insulation materials like EPS and XPS, rock wool boards do not burn or emit toxic fumes under high temperatures. Additionally, the melting point of rock wool is approximately 1000°C or higher, substantially surpassing the temperature of typical building fires (usually ranging from 600°C to 800°C). In the event of a fire, rock wool boards can maintain structural stability without softening or dripping, and they are capable of withstanding high temperatures for an extended period, thereby buying time for escape and fire suppression.
Advantages
Rock wool boards have notable advantages, widely preferred in diverse applications. Made from inorganic minerals like basalt, they are Class A non-combustible, resisting high temperatures without toxic fumes—unlike flammable plastics. They excel in thermal insulation too, with fibrous, porous structures ensuring low thermal conductivity, slowing heat transfer and boosting energy efficiency. Hydrophobic variants offer reliable moisture resistance (≤5% water absorption, ≤3% for high-quality ones), staying stable in humidity. They also provide sound insulation, while chemical stability and corrosion resistance ensure long life. Non-toxic and eco-friendly, they fit sustainable practices.
Applications
Rock wool boards find use in various additional scenarios. In construction, they’re applied to internal partition walls for fire and sound insulation, and as insulation in basement walls to resist moisture and temperature changes. Industrial furnaces and kilns utilize them for high-temperature insulation to improve energy efficiency. They’re also used in data centers to insulate server rooms, aiding temperature control. In transportation, they insulate train engine compartments and bus bodies. For cold storage facilities, they help maintain stable low temperatures. Historic building renovations often employ them for their non-intrusive insulation and fire safety.
Comparison of Fire Resistance Performance Between Rock Wool Boards and Other Building Materials
| Building Materials | Fire Performance Class | Fire Resistance Rating (Typical Value) | Characteristics When Burning | Applicable Scenarios |
| Rock Wool Board | Class A1 (Non-combustible) | 1-4 hours | Does not burn, no open flame, maintains structural stability at high temperatures, only slightly shrinks | Wall insulation, ceiling, fire barrier zone |
| Expanded Polystyrene Board (EPS) | Class B2 (Combustible) | 0.1-0.3 hours | Easy to burn, releases a large amount of black smoke and toxic gases (such as carbon monoxide) when burning, with fast fire spread | Non-load-bearing insulation layer of low-rise buildings (requires additional fire protection treatment) |
| Polyurethane Foam Board (PU) | Class B3 (Flammable) | ＜0.1 hours | Highly flammable, with fast flame propagation speed, releases toxic hydrogen cyanide gas, melts and drips at high temperatures | Strictly restricted in use, only applicable to non-exposed scenarios with tight fire protection cladding |
| Glass Wool Board | Class A1 (Non-combustible) | 0.5-2 hours | Does not burn, stable performance at high temperatures, but structural strength is slightly weaker than rock wool boards | Ventilation duct insulation, light partition walls |
| Aerated Concrete Block | Class A3 (Non-combustible) | 3-6 hours | Does not burn, resistant to high temperatures, and its own structure can be used as a fire separation component | Fire walls, load-bearing walls |
| Paper-faced Gypsum Board | Class A2 (Flame-retardant) | 0.5-1.5 hours | Gypsum dehydrates and hardens to form a fire-resistant layer after encountering fire, delaying fire spread; the paper layer will burn but not support combustion | Ceiling, partition walls, fireproof board base material |
