? Key Takeaways
? Density is the single most critical parameter for rock wool sandwich panel performance — it affects fire resistance, acoustic performance, mechanical strength, weight, and cost.
? All density ranges achieve Class A fire rating, but fire resistance increases with density: 1-2 hours for 60-80 kg/m³, 2-3 hours for 100-120 kg/m³, 3-4 hours for 120-150 kg/m³.
? Acoustic performance improves with density: 25-30 dB for 60-80 kg/m³, 30-35 dB for 100-120 kg/m³, 35-40 dB for 120-150 kg/m³.
? Cleanroom standard density is 100-120 kg/m³ — balancing fire performance, acoustic performance, and cost.
⚠️ Density is often where suppliers cut corners — always verify density through test reports and physical samples.
? SAMZOON provides density-verified rock wool sandwich panels covering 60-150 kg/m³, with test reports and free samples for physical verification.
