FAQs:
  • What is the fire rating of this rock wool board?
    Our rock wool board has a Class A1 non-combustible rating, which is the highest fire performance classification. It does not burn and maintains structural stability at high temperatures up to 650℃, providing 1-4 hours of fire resistance depending on the application.
  • How does this insulation perform in moist environments?
    The rock wool board features superior hydrophobic properties with water absorption rates of ≤5% (≤3% for premium grades). This ensures reliable moisture resistance and prevents performance degradation in humid conditions or wet applications.
  • What applications are suitable for this fireproof rock wool board?
    This versatile insulation is suitable for building insulation in walls, ceilings, and partition walls; industrial furnace and kiln insulation; data center temperature control; transportation insulation in trains and buses; cold storage facilities; and historic building renovations.
  • How does rock wool compare to other insulation materials in fire safety?
    Unlike combustible materials like EPS (Class B2) and polyurethane foam (Class B3) that release toxic fumes and spread fire quickly, rock wool maintains Class A1 non-combustible properties, does not burn, and provides significantly longer fire resistance from 1-4 hours.
