Magnesium oxide wall board is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products.
Magnesium Oxide Wall Panels are cementitious substrate products reinforced with magnesium oxide fibre matting.
Fire resistant magnesium oxide wallboard is a new type of refractory material. It is widely used primarily as a wallboard alternative to conventional gypsum-based drywall and plywood.
It is non combustible and fire rated Class A1. With options for up to a 2 hour fire resistance, MgO Board offers an innovative passive fire protection alternative for your construction projects.
MgO board has very good fire performance. It does not spread flames or smoke. It is noncombustible and fire-rated A1, which helps protect homeowners, tenants and building occupants while mitigating damage and loss.
Magnesium oxide wall board is made of magnesium oxide, magnesium sulfate or magnesium chloride, glass fiber mesh, perlite and wood fiber.
It is an upgraded product of fireboard. A properly constructed assembly with our MgO fireproof wall board can achieve a 3-hour fireproof rating.
Fire Resistant Internal Wall Board
Our Fire Resistant Internal Wall Board is a fiberglass reinforced magnesium oxide cement board. It can be used to replace traditional gypsum drywall for wall and ceiling finishes and sheathing.
Fireproof Exterior Wall Panels
Magnesium oxide board is a new type of fire-resistant building material. The main raw materials are magnesium oxide, magnesium chloride/sulfate and perlite.
Fireproof Magnesium Oxide Board (MgO Board) Exterior Wall Cement Partition is an exterior wall-specific partition system composed of MgO board as the core panel, combined with cement-based auxiliary materials and thermal insulation core materials. Its core advantages lie in integrating four key functions: Class A fire resistance, structural load-bearing, moisture and weather resistance, and thermal insulation, making it suitable for exterior wall separation and fire partition requirements in buildings.
Advantages of Magnesium Oxide Board Fire Proof Exterior Wall Cement Partition
1. Fire Resistance and Flame Retardancy
MgO board itself is a Class A1 non-combustible material. When combined with rock wool core material, the overall system achieves Class A1 fire resistance, with a fire resistance rating of 1-2.5 hours.
It does not release toxic gases under high temperatures, only producing a small amount of harmless smoke, complying with exterior wall fire partition specifications.
2. Weather and Water Resistance
After cement-based coating treatment, the panel has a water absorption rate ≤8%. It does not mold or deform when exposed to wind and rain for a long time, and resists cracking under freeze-thaw cycles (-20℃~60℃).
Joints are sealed with weather-resistant sealants. Combined with the closed-cell structure of XPS/PU core materials, the overall system has excellent water and moisture resistance, capable of preventing rainwater penetration into the exterior wall.
3. Structural and Wind Pressure Resistance
MgO board has a flexural strength ≥12MPa. When matched with light steel keels, the overall impact resistance is ≥5kJ/m², which can withstand exterior wall-level wind pressure (≥0.5kPa), suitable for exterior walls of low-to-medium-rise buildings.
Cement-based auxiliary materials enhance structural stability. The system does not warp or deform during long-term use and can be directly used as an exterior wall enclosure partition without the need for additional load-bearing frames.
4. Thermal Insulation and Energy-Saving Performance
Core performance relies on thermal insulation core materials. The overall thermal conductivity is as low as 0.028-0.045W/(m・K), meeting building energy-saving standards in different climate zones.
It blocks heat transfer between indoor and outdoor spaces in winter and reduces external high-temperature penetration in summer, lowering building air conditioning energy consumption.
Application Scenarios of Magnesium Oxide Board Fire Proof Exterior Wall Cement Partition
- Exterior Wall Separation in Buildings: Used for household partition walls of exterior walls in residences, commercial buildings, and office buildings. It replaces traditional brick walls, saving wall thickness (only 80-150mm).
- Fire Partition Zones: Applied in exterior wall fire partitions of high-rise buildings, industrial plants, and warehouses, meeting fire code requirements.
- Exterior Walls in Special Environments: Suitable for exterior walls of underground garage entrances and exits, kitchen and bathroom exterior walls (high-humidity scenarios), and exterior walls of buildings in coastal areas (salt spray and moisture resistance).
- Temporary/Precast Buildings: Used as exterior wall partitions for movable board houses, sentry boxes, and prefabricated residences, balancing rapid construction and weather resistance.
- Industrial Building Exteriors: Enclosure walls for data centers and chemical plants, adapting to multiple requirements of fire resistance, moisture resistance, and impact resistance.
Key Installation Points Magnesium Oxide Board Fire Proof Exterior Wall Cement Partition
Fixing Method: Adopts dual fixation with exterior wall-specific expansion anchors and keels. The anchor spacing ≤500mm ensures wind pressure and earthquake resistance.
Joint Treatment: Reserve 5-8mm expansion joints at panel joints, filled with weather-resistant sealant and foaming agent to prevent rainwater penetration and cracking due to thermal expansion and contraction.
Thermal Insulation Connection: The thermal insulation core material must be tightly connected to the overall exterior wall thermal insulation system to avoid heat bridge effects. In cold regions, the thickness of the core material needs to be increased.
Surface Treatment: After installation, exterior wall weather-resistant paint, ceramic tiles, or stone can be applied to enhance aesthetics and weather resistance.
