Product Introduction
Magnesium Oxide Board for Resilient Construction
Magnesium Oxide Board (commonly known as MGO Board) is one of the core panels for resilient construction. Made from natural minerals and reinforced with fiberglass, it integrates Class A1 fire resistance, excellent waterproofing, high strength & impact resistance, weather durability, and environmental friendliness. It greatly improves structural resilience and safety redundancy under extreme conditions such as fire, flood, earthquake, high humidity, and corrosion. It is a high-performance green building material that replaces gypsum board, wood-based panels, and cement boards.
Advantages of Magnesium Oxide Board for Resilient Construction
Extreme Fire Resistance (Class A1 Non-Combustible)
- Fire rating: Class A1 non-combustible (ASTM E84/UL 723: flame spread index 0, smoke index 0; EN 13501-1 Class A1)
- Temperature resistance: Stable at 800°C for 2–3 hours without burning, melting or dripping; no discoloration or structural failure at 750°C for 30 minutes
- High-temperature behavior: Forms a dense ceramic isolation layer to block fire; no smoke, no toxic gas
- Value: Ideal for hospitals, schools, malls, data centers, steel structures requiring high fire resilience
Superior Waterproof & Moisture Resistance
- Water absorption: Only 0.34% (much lower than gypsum board ~3%, wood panels >15%)
- Water stability: No expansion, deformation, softening or halogenation after soaking in water
- Mold & termite resistance: Inorganic material, no mold, termites or fungi
- Value: Improves durability against heavy rain, flood and high humidity
High Strength & Structural Toughness
- Bending strength: 18–32MPa (gypsum board only 5.6MPa, cement board 10–15MPa)
- Impact strength: >5KJ/m² (2–3 times that of standard gypsum board walls)
- Mechanical performance: Balances rigidity and flexibility; absorbs energy during earthquakes
- Value: Enhances seismic resilience and damage resistance
Weather Durability & Corrosion Resistance
- Weather resistance: Stable from -40°C to 120°C; freeze-thaw resistant, anti-aging, deformation-free
- Corrosion resistance: Acid, alkali, salt spray resistant; MgSO₄-based MGO does not corrode metal studs
- Service life: Over 50 years (gypsum board: 10–15 years; wood panels: 5–10 years)
Green & Eco-Friendly
- Eco-performance: 100% asbestos-free, formaldehyde-free, heavy metal-free, non-radioactive
- Health performance: Inorganic microporous structure regulates humidity; non-toxic in fire
- Low-carbon value: Replaces high-carbon wood and high-energy cement boards
Easy Construction & Fast Repair
- Lightweight: 10mm board ≈ 10.07kg/m²; reduces foundation and structural costs
- Processable: Sawable, drillable, nailable, tileable, paintable
- Rapid repair: Easily replaced after disasters, improves post-disaster resilience

Magnesium Oxide Board for Resilient Construction
1. Basic Definition & Core Composition
Definition
- An inorganic non-combustible panel mainly made of high-purity magnesium oxide (MgO) as the cementitious phase, stabilized with magnesium chloride / magnesium sulfate (MgCl₂/MgSO₄) and water, reinforced with medium-alkali fiberglass mesh, filled with perlite, plant fiber, lightweight aggregates, etc., through modification, compounding, and curing.
Core Composition (Asbestos-Free, Formaldehyde-Free, Radiation-Free)
- Cementitious material: High-purity active MgO (melting point 2852°C, stable at high temperature), MgCl₂/MgSO₄ (setting adjustment & reinforcement)
- Reinforcement: Medium-alkali fiberglass mesh (improves bending / impact toughness, prevents cracking)
- Fillers: Perlite, lightweight ceramsite, plant fiber (lightweight, thermal insulation, toughening)
- Modifiers: Polymer, anti-halogenation agent (solves halogenation and corrosion of traditional MGO)
Standard Sizes (For Modular Resilient Construction)
- Standard dimensions: 1220×2440mm, 1200×2400mm, 910×1800mm; max length 3660mm, max width 1220mm
- Thickness: 3–25mm (commonly 6/8/10/12/15mm for walls, ceilings, floors, fire compartments)
- Edge types: Square edge, chamfered edge, T&G edge, overlapping edge (for fast installation and sealing)
- Density: 0.85–1.27g/cm³ (lightweight and high-strength, reduces building dead load)
Building Structure
Interior & exterior walls: Load-bearing / non-load-bearing partitions
Floor & subfloor: High bending strength for LOFT, steel structures
Roof & ceiling: Class A1 fireproof + waterproof
High-Safety Resilient Areas
Fire compartments & firewalls: 2–3 hours fire resistance
Emergency exits & escape routes: Non-toxic, non-smoke in fire
Data centers & server rooms: Fireproof, moisture-proof, anti-electromagnetic interference
Hospitals, schools, senior care: Healthy, fire-safe, mold-resistant
Extreme Environment Buildings
Coastal & high-humidity buildings: Waterproof, salt-spray resistant
Basements & civil defense: Moisture-proof, mold-proof, fire-resistant
Industrial buildings & warehouses: Impact-resistant, acid & alkali resistant
Prefabricated & Modular Buildings
Prefabricated wall panels, modular containers, prefabricated houses for factory production & on-site assembly
