How GB 55037-2022 General Fire Code Affects Board Selection
GB 55037-2022 is a mandatory engineering code setting hard requirements for reaction-to-fire and fire resistance of partitions, ceilings and smoke ducts. Key points: determine reaction class by location (Class A non-combustible preferred for occupied/egress areas), determine fire resistance by system and demand full assembly test reports — a compliant board does not alone make a compliant system.
Magnesium Board vs Fiber Cement/Calcium Silicate vs Gypsum: Fire, Moisture & Price
Magnesium boards reach Class A1 non-combustible, are moisture-proof and formaldehyde-free, outperforming gypsum board overall and offering better toughness and screw-holding than calcium silicate in fire/moisture scenarios. Gypsum is cheap but weaker in fire and moisture. Choose magnesium for fire/humid uses; gypsum for dry, low-cost ceilings.
Magnesium Board Fire Rating: What Class A1 Non-combustible Really Means
Class A1 is the highest grade in GB 8624-2012: the material undergoes virtually no flaming combustion and releases negligible heat or smoke in a fire. Magnesium boards as inorganic products can reach A1 — but an A1 board is not automatically an A1 system; partition/duct fire resistance also depends on assembly and installation.
