Composed mainly of natural ores like basalt with a melting point exceeding 1000℃, our rock wool boards maintain structural integrity and thermal insulation performance even in fire-induced high temperatures (600-800℃). They resist softening, dripping, or collapsing while releasing only minimal harmless smoke—no toxic fumes—significantly reducing poisoning risks in high-fire-risk scenarios.
Classified as non-combustible materials meeting international standards, these boards neither burn nor support combustion under open flame or high temperatures. Their fire resistance rating of 1-4 hours (adjustable by thickness) effectively blocks flame spread, providing critical evacuation time in applications like:
As core filling or isolation materials, rock wool boards serve in:
| Material | Fire Resistance Performance | Main Advantages | Application in Fire Barriers |
|---|---|---|---|
| Rock Wool Board | Class A non-combustible, 1-4 hour rating, no toxic fumes, melting point >1000℃ | Combines fire resistance with thermal insulation, strong weather resistance, good construction compatibility | High-rise external walls, curtain wall separations, pipe shaft isolation |
| Glass Wool | Class A non-combustible, 0.5-2 hour rating, low smoke emission, ~600℃ melting point | Lightweight, superior sound insulation, lower cost | Internal walls, ventilation duct interlayers |
| Fireproof Board (Calcium Silicate) | Class A non-combustible, 2-6 hour rating, structurally stable | High strength, excellent flatness, direct facing use | Firewall main bodies, cable tray separations |
| Intumescent Fire Retardant Coating | Class B1 flame-retardant, 0.5-3 hour rating | Direct substrate application, convenient for special shapes | Steel structures, complex components |
| Mineral Wool Board | Class A non-combustible, 1-3 hour rating, higher thermal conductivity | Low cost, basic fire resistance | Non-critical areas in standard buildings |
