Magnesium Oxide Facade System

Magnesium Oxide Facade System

1. Core Material: Magnesium Oxide (MgO) Board

1.1 Basic Composition

Magnesium Oxide board uses MgO as the main cementitious material, mixed with magnesium chloride / magnesium sulfate, glass fiber mesh, perlite / vermiculite, inorganic fillers and modifiers, pressed and cured.

MOC Type (Magnesium Oxychloride Board): High strength, fast early strength, but contains chloride ions, easy to absorb moisture and cause halogen return, which may corrode metal components.

MOS Type (Magnesium Oxysulfate Board): Chloride-free, better water resistance and moisture resistance, no halogen return, more suitable for exterior walls and humid environments.

1.2 Key Properties

Fire Resistance: Class A1 non-combustible, no toxic smoke, fire resistance up to 2–3 hours.

Weather & Moisture Resistance: Low water absorption, stable dimension, freeze-thaw resistance, mold-proof and termite-proof.

Structural Strength: Excellent bending and impact resistance, strong nail-holding power.

Eco-Friendly: No formaldehyde, no asbestos, no VOC, recyclable.

Workability: Sawable, drillable, nailable, bondable, suitable for dry-hanging and pasting.

2. System Structure (Typical Dry-Hanging Facade)

Base Structure Layer: Concrete wall, masonry wall or steel structure.

Leveling & Moisture-Proof Layer: Cement mortar leveling.

Suspension & Support System: Galvanized steel / aluminum alloy keel, connectors.

Core Board Layer: MgO board, fixed by dry-hanging or adhesive.

Thermal Insulation Layer: Rock wool, XPS, SEPS, etc.

Waterproof & Sealing Layer: Weather-resistant silicone sealant.

External Finish Layer: Fluorocarbon paint, real stone paint, ceramic tile, stone, etc.

 

 

3. System Advantages

High Safety: Excellent fireproofing, wind resistance, earthquake resistance.

High Durability: Long service life, low maintenance cost.

Efficient Construction: Dry operation, fast installation, less affected by weather.

Green & Healthy: Non-toxic, eco-friendly, no harmful emissions.

Design Flexibility: Supports various shapes and exterior finishes.

4. Applications

Residential buildings, villas, high-rise apartments

Commercial buildings: shopping malls, hotels, offices, schools, hospitals

Industrial buildings: workshops, warehouses

Modular & prefabricated buildings

Coastal and humid areas (using chloride-free MgO board)

5. Limitations & Precautions

Avoid MOC boards for exterior walls: Risk of halogen return and metal corrosion.

Use MOS chloride-free boards for exterior facade systems.

Reserve expansion joints and use professional sealants.

Keel must be anti-corrosion treated.

6. Comparison with Traditional Systems

MgO Facade System: A1 non-combustible, waterproof, durable, long service life.

Traditional Cement Board: Good fireproofing but poor water resistance.

Gypsum Board: Poor water resistance and durability.

FAQ:

Q: How should I store the panels?
A: Store the boards flat on a well-supported, elevated surface in a cool, dry environment, keeping them in the manufacturer's original packaging until use. If storing outdoors or on-site, cover them with waterproof material to protect against weather, direct sunlight, surface contamination, and construction traffic.

Q: How do I cut the panels?
A: MgO boards are optimally cut with carbide-tipped tools, which ensure clean, square edges for higher-quality installations. Circular saws-including table saws-are the preferred tools. For thin sheets, score the fiberglass mesh from the smooth side using a disposable knife, then snap the sheet along the scored line.
