💡 Detailed Recommendations
-
💧 Extreme high-humidity environment (pharmaceutical, cold storage): Directly consider magnesium oxysulfate panels with minimal halogen return risk and better surface stability. SAMZOON provides free samples for physical quality verification.
-
🔥 Fire-rated cleanroom (2+ hours fire resistance required): Magnesium-rock wool panels offer longer fire resistance (1-3 hours) — suitable for fire-rated applications.
-
💰 Budget-sensitive, moderate-humidity environment: Magnesium-rock wool panels offer lower initial cost — suitable for cost-sensitive projects.
-
⚖️ Weight-sensitive application: Magnesium oxysulfate panels offer lighter weight — reduces structural load and eases installation.
🎯 Key Takeaways
-
🧱 Magnesium-rock wool panel = fire resistance priority (1-3 hours, lower cost); magnesium oxysulfate panel = extreme moisture resistance priority (anti-halogen, better surface stability).
-
🔥 Fire rating: both achieve Class A — but magnesium-rock wool offers longer fire resistance (1-3 hours vs 1-2 hours).
-
💧 Moisture resistance: both offer good moisture resistance — but magnesium oxysulfate offers better surface stability and minimal halogen return risk.
-
⚠️ Halogen return risk: magnesium-rock wool may have risk in poor-quality products; magnesium oxysulfate has minimal risk due to oxysulfate structure.
-
🎯 Scenario-based selection matters more than price comparison: magnesium-rock wool for fire-rated and moderate-humidity applications; magnesium oxysulfate for extreme high-humidity environments.
-
🏭 SAMZOON provides both magnesium-rock wool and magnesium oxysulfate panels, with selection guidance based on application requirements and humidity conditions for South China projects.
