? Detailed Recommendations
? Hospital, cleanroom, office (lightweight + acoustic priority): Directly consider hollow magnesium boards with Class A fire rating, 30-40 dB acoustic performance, and lighter weight. SAMZOON provides free samples for physical quality verification.
? Industrial equipment mounting, heavy load-bearing: Directly consider solid magnesium boards with Class A fire rating and heavy equipment load-bearing capacity.
⚖️ Weight-sensitive application (structural load concern): Hollow magnesium boards offer lighter weight (12-22 kg/m²) — reduces structural load and eases installation.
? Fire-rated enclosure (2+ hours fire resistance required): Solid magnesium boards offer longer fire resistance (1-3 hours) — suitable for applications with strict fire acceptance requirements.
? Budget-sensitive, lightweight priority: Hollow magnesium boards offer lower initial cost and lower structural support cost — suitable for cost-sensitive projects.
? Key Takeaways
? Hollow magnesium boards and solid magnesium boards both achieve Class A non-combustible fire rating — the difference lies in weight, acoustic performance, and load-bearing capacity.
? Acoustic performance: hollow magnesium boards offer better acoustic performance (30-40 dB) than solid boards (25-35 dB) due to the hollow cavity structure.
⚖️ Weight: hollow magnesium boards are lighter (12-22 kg/m²) than solid boards (18-30 kg/m²) — reducing structural load and easing installation.
? Load-bearing capacity: hollow magnesium boards are suitable for general partition; solid magnesium boards are suitable for heavy equipment mounting.
? Cost: hollow magnesium boards offer lower initial cost and lower structural support cost; solid magnesium boards cost more but offer better load-bearing capacity.
? SAMZOON provides both hollow and solid magnesium boards, with selection guidance based on application requirements for South China projects.
