Product Introduction
Magnesium Oxide Board Class a Non Combustible 1220x2440 Exterior MGO Wall Panel
Designed exclusively for exterior building envelopes, the 1220x2440mm Class A1 Non-Combustible MgO Exterior Wall Panel stands out as a high-performance, weather-resistant solution tailored to modern construction demands. Crafted with high-activity magnesium oxide as the core substrate, reinforced by alkali-resistant glass fiber mesh, and bonded with inorganic composite binders, this panel integrates fire safety, structural stability, and long-term weather resistance-addressing key pain points of exterior wall materials such as flammability, weathering degradation, and poor dimensional adaptability. Its 1220x2440mm standard size is optimized for large-scale construction, reducing cutting waste and improving on-site efficiency, making it a preferred choice for high-rise buildings, industrial facilities, and residential villas across diverse climatic zones.
The 1220x2440mm specification is a universal standard in the construction industry, and this MgO exterior panel is engineered to match this dimension perfectly. Compared with non-standard sizes, it offers three core benefits for exterior construction: first, minimizing on-site cutting operations, reducing material waste by over 15% and shortening construction cycles; second, fitting seamlessly with standard exterior wall keel systems, improving installation precision and structural firmness; third, adapting to both new construction and old building renovation projects, compatible with common exterior wall insulation and cladding systems. As a dedicated exterior material, it is thicker and denser than interior MgO panels, ensuring sufficient load-bearing capacity and weather resistance for outdoor use.
Advantages of Magnesium Oxide Board Class a Non Combustible 1220x2440 Exterior MGO Wall Panel
1. Class A1 Non-Combustible Fire Protection: Safeguard Exterior Envelopes
Certified to EN 13501-1 and GB 8624-2012 Class A1 non-combustible standards, this panel is a critical fire-resistant component for exterior walls. Unlike flammable exterior materials such as EPS cladding or color steel plates, it does not ignite, melt, or drip when exposed to open flames. Even under high temperatures up to 1200℃, it maintains structural integrity without collapsing, forming an effective fire barrier to prevent flame spread between floors-especially essential for high-rise buildings where exterior fire risks are prominent. Moreover, it releases no toxic or corrosive fumes during combustion, avoiding secondary environmental pollution and ensuring the safety of construction workers and residents.
2. Superior Weather Resistance: Adapt to Harsh Outdoor Environments
Targeting the challenges of outdoor exposure-UV radiation, rain erosion, temperature fluctuations, and acid-alkali corrosion-this MgO exterior panel features a specially optimized inorganic matrix. Its surface is treated with a weather-resistant coating that resists UV aging, preventing discoloration, chalking, or cracking after long-term sun exposure. With a 24-hour water absorption rate ≤14% and excellent freeze-thaw resistance (passing 50 freeze-thaw cycles without damage), it performs stably in humid coastal areas, cold northern regions, and industrial zones with acid rain. It effectively resists mold, mildew, and salt spray erosion, ensuring no deformation or degradation even in extreme climates.
3. Strong Structural Stability: Resist Wind Pressure & Loads
Exterior walls must withstand wind pressure, structural loads, and external impacts. This MgO panel has a density of 850-1050 kg/m³, a flexural strength ≥9 MPa, and a compressive strength ≥18 MPa-far exceeding the requirements of ordinary exterior wall sheathing. It can resist wind pressure up to 0.8 kPa (suitable for high-rise buildings above 30 floors) and bear the weight of external cladding materials such as stone veneer and metal panels without additional reinforcement. Its low thermal expansion coefficient (≤8×10⁻⁶/℃) ensures no warping or cracking due to temperature changes, maintaining a flat exterior surface for over 25 years.
4. Environmental & Durable: Low Carbon & Long Service Life
Made from natural magnesium ore (a renewable resource) and 100% inorganic components, the panel contains no VOCs, formaldehyde, or asbestos. It meets green building standards such as LEED and BREEAM, with zero pollutant emissions during production and 100% recyclability at the end of its service life. Unlike traditional exterior materials that require frequent renovation (e.g., every 10-15 years), this MgO panel has a service life of ≥25 years, reducing long-term maintenance costs and environmental pressure from material replacement.
5. Versatile Compatibility: Integrate with Exterior Wall Systems
It is highly compatible with common exterior wall systems, including external insulation composite systems (EIFS), curtain wall systems, and dry-hanging systems. It can be used as a base panel for insulation cores (such as rock wool or XPS), a backing board for decorative cladding, or a standalone exterior sheathing. Its smooth and flat surface allows direct application of exterior paint, waterproof coatings, or decorative films, eliminating the need for complex surface treatment and realizing an integrated solution for fire protection, insulation, and decoration.
6. Cost-Effective Construction: Save Time & Labor
The 1220x2440mm large-size design reduces the number of joints during installation, improving construction efficiency by 20% compared with small-size panels. The panel is lightweight (about 25 kg per sheet) and can be cut, drilled, and fixed with ordinary construction tools, requiring no professional equipment. Its high dimensional accuracy (edge straightness error ≤0.5mm/m) ensures tight joints, reducing the need for subsequent sealing and maintenance work-comprehensively lowering labor and material costs for projects.
