🎯 Key Takeaways
-
🔥 Rock wool sandwich panels achieve Class A non-combustible fire rating (GB 8624) — the most widely used fire-rated core in cleanroom and medical applications.
-
⏱️ Fire resistance ranges from 1-4 hours depending on density, thickness, and system assembly: 50mm/100-120 kg/m³ achieves 1-2 hours; 100mm/120-150 kg/m³ achieves 3-4 hours.
-
🏥 Application mapping shows that hospitals, cleanrooms, and pharmaceutical GMP typically require 1-2 hour fire resistance; high-rise buildings and fire-rated cold storage require 2-3 hours.
-
📊 Density and thickness together determine fire resistance — higher density and greater thickness both improve performance.
-
⚠️ System-level compliance is critical — fire resistance depends on the entire assembly (core, thickness, connections, sealing), not just the core material alone.
-
🏭 SAMZOON provides rock wool sandwich panels with type test reports covering your ordered specification, with density verification and free samples for physical inspection.
