💡 Detailed Recommendations
🏥 Cleanroom, hospital, laboratory: Directly consider hollow magnesium boards with Class A fire rating, moisture resistance, and cleanability. SAMZOON provides free samples for physical quality verification.
🏢 Office building, retail store: Both options are viable depending on budget and design requirements. Hollow magnesium boards offer faster installation, better cleanability, and relocatability; gypsum board offers lower cost and greater design flexibility.
💧 High-humidity or wet area: Hollow magnesium boards with moisture-resistant cores are preferred over gypsum board, which is moisture-sensitive.
🔄 Projects requiring future relocation: Hollow magnesium boards are relocatable and reusable; gypsum board partitions are difficult to relocate without damage.
💰 Budget-sensitive general office or residential: Gypsum board partitions can suffice, but you must accept moisture sensitivity and limited cleanability.
🎯 Key Takeaways
🧱 Hollow magnesium boards offer dry assembly, Class A fire rating options, moisture resistance, and cleanroom suitability — but at a higher cost per m².
🏗️ Gypsum board partitions offer lower cost and design flexibility — but are moisture-sensitive, not suitable for cleanrooms, and difficult to relocate.
🔥 Fire rating: both systems can achieve Class A, but hollow magnesium boards offer Class A non-combustible cores as standard, while gypsum board depends on system assembly.
💧 Moisture and cleanability: hollow magnesium boards significantly outperform gypsum board in moisture resistance and surface cleanability.
🎧 Acoustic performance: gypsum board partitions offer slightly better acoustic performance (35-45 dB vs 30-40 dB) due to mass and insulation.
🏭 SAMZOON provides hollow magnesium boards with Class A fire rating and moisture resistance, with selection guidance based on application requirements for South China projects.
