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:
- External wall insulation in high-rise buildings
- Industrial firewalls
- Fire-resistant bulkheads in ships
As core filling or isolation materials, rock wool boards serve in:
- External wall insulation systems
- Curtain wall structures
- Pipe shafts and cable trays
- Continuous vertical/horizontal fire barriers in high-rises
- Segmented isolation in pipe shafts
- High fire safety: Meets GB 50016 building codes with no flame spread risk
- Environmental adaptability: Resists high/low temperatures and aging, stable in humid/dry conditions (20+ year lifespan)
- Construction flexibility: Easily cut to fit tightly with base layers, reducing gap-related risks
- Eco-friendly: Inorganic composition releases no harmful substances
