Eco-Friendly Fireproof Wall Board Non-Combustible Magnesium Oxide (MgO) Panels

A: MgO boards hold the highest international fire rating Class A1, non-combustible at 800℃ and flame-free at 1200℃. A 12mm thick board has a fire resistance limit of up to 120 minutes. They do not release toxic gases like CO or HCN during fires, nor do they produce pungent odors, providing ample time for evacuation. Compliant with GB 8624-2012 fire standards, they are an ideal choice for building fire compartments.

A: Fully eco-friendly and safe. MgO boards are made primarily from inorganic minerals, free of formaldehyde, asbestos, benzene, and radioactive substances, with nearly zero VOC emissions, meeting E0-class environmental standards. Waste boards are 100% recyclable, and the production process saves 30% more energy than traditional cement products, combining usage safety with environmental sustainability.

A: Highly suitable. With a water absorption rate of ≤3%, MgO boards offer excellent moisture and water resistance, without swelling, deformation, or mold growth in high-humidity environments. Magnesium sulfate-based MgO boards are particularly recommended for wet areas, as they avoid chloride ion corrosion and maintain structural stability over long-term use, making them an ideal choice for bathroom partitions and kitchen ceilings.

A: Installation is convenient without complex processes, but professional teams are recommended for optimal results. Boards can be directly fixed to light steel or wooden keels using 316 stainless steel screws (spacing ≤300mm), with 3-5mm gaps left between boards for joint filling. Skilled workers can complete large-area installation in one day, with construction efficiency 50% higher than traditional cement boards, and no special tools are needed.

A: Yes. MgO boards have good weather resistance, maintaining stable density and strength without aging or cracking when exposed to sunlight, wind, and rain for a long time. For outdoor use, enhanced MgO boards (thickness ≥10mm) are recommended, and the surface can be coated with special weather-resistant paint to further improve UV and corrosion resistance. They are suitable for exterior wall decoration, tunnel lining, outdoor billboards, etc.

A: The core advantages lie in three aspects: ① Superior fire resistance: Class A1 non-combustible vs. gypsum board Class B1 and cement board Class A, with longer fire resistance time; ② Outstanding moisture resistance: No water absorption or deformation, while gypsum boards soften when wet and cement boards are heavy; ③ Eco-friendly and lightweight: Formaldehyde-free, with a density only 1/3 of cement boards for easier installation, and strength exceeding 15MPa, far superior to gypsum boards.

A: The service life can reach over 25 years under normal usage conditions. MgO boards have minimal thermal expansion and contraction rates, excellent dimensional stability, and are not prone to deformation. Their inorganic composition contains no nutrients, naturally resisting termites, borers, and mold growth. As long as installed properly (e.g., compliant keel spacing, secure screw fixation) and not long-term soaked in water, they can maintain stable performance for a long time.

A: Cutting and processing are simple, achievable with ordinary electric saws or utility knives, featuring high processing precision and supporting various processes such as bending and drilling. Daily maintenance requires no special measures: ① Avoid violent impact with sharp objects to prevent board damage; ② Wipe surface stains with a damp cloth; ③ For wet area use, regularly check the sealing of board joints and refill with joint compound if cracks appear to extend service life.

A: MgO boards are very easy to cut despite being as strong as stones. Using a thin carbide saw (low speed and circular) would work best. However, angle grinders can be used as well. It's also possible to simply score and snap using a razor, but it wouldn't give an immaculate finish.

A: MGO board can be fixed to both timber or steel frames, and must be supported at the edge, at intermediate positions. Screws should be at least 12mm from the edges and 50mm from corners. The board can be nailed directly into timber supports. It's best to use a nail gun so the board is less likely to break.
