? Detailed Recommendations
? High-humidity cleanroom, pharmaceutical, food processing: Directly consider magnesium-rock wool panels with Class A fire rating and enhanced moisture resistance. SAMZOON provides free samples for physical quality verification.
? Fire-rated enclosure (3+ hours fire resistance required): Rock wool panels with higher density offer longer fire resistance — suitable for applications with strict fire acceptance requirements.
? Budget-sensitive, general cleanroom: Rock wool panels offer lower cost — but you must accept higher moisture risk and require hydrophobic treatment (≥98%).
⚖️ Weight-sensitive application (structural load concern): Magnesium-rock wool panels offer lighter weight — reduces structural load and eases installation.
? Key Takeaways
? Magnesium-rock wool panel offers better moisture resistance, lighter weight, and easier machinability; rock wool panel offers longer fire resistance and lower initial cost.
? Fire rating: both achieve Class A — but rock wool offers longer fire resistance (1-4 hours vs 1-3 hours).
? Moisture resistance: magnesium-rock wool panels offer better moisture resistance with the magnesium layer providing protection; rock wool requires hydrophobic treatment (≥98%).
⚖️ Weight and machinability: magnesium-rock wool panels are lighter and easier to cut; rock wool panels are heavier and more difficult.
? Lifecycle cost: magnesium-rock wool panels offer lower lifecycle cost in high-humidity environments; rock wool panels are cheaper in general cleanrooms.
? SAMZOON provides both magnesium-rock wool and rock wool panels, with selection guidance based on application requirements and fire acceptance path for South China projects.
