Guided by our commitment to innovation and sustainability, we provide high-performance materials that support the future of green construction.

Fireproof MGO Cladding Board is a non-combustible cladding material made from inorganic minerals, designed to provide fire protection, weatherproofing, and decorative functionality for building exteriors and interiors. It combines the inherent fire resistance of MGO (magnesium oxide) with enhanced formulas for outdoor durability, making it suitable for both load-bearing and non-load-bearing cladding systems.

1. Fire Resistance (Class A1, Non-Combustible)

Fire Rating: Complies with EN 13501-1 Class A1, ASTM E136 Class A, and GB 8624-2012 A1 standards – highest fire rating for building materials.

Key Fire Properties:

Sustained combustion time: 0 seconds; no open flames at 1200℃.

Fire resistance limit: Up to 2-4 hours when used with fireproof sealants and keel systems.

Toxicity: Releases only water vapor and inert gases during combustion – no formaldehyde, smoke, or toxic fumes (meets EN 13501-1 Smoke Toxicity Class SA).

2.  Weather & Moisture Resistance

Outdoor Durability: Withstands extreme temperatures (-40℃ to 70℃), UV radiation, and heavy rainfall – no fading, warping, or delamination after 5+ years of outdoor exposure.

Water Resistance: Water absorption rate ≤ 8% (ASTM D1037 standard); no swelling or softening even after 72 hours of water immersion.

Corrosion Resistance: Chlorine-free formulation avoids galvanic corrosion when in contact with steel structures or fasteners – ideal for coastal or high-humidity regions.

3. Structural Stability & Impact Resistance

Lightweight yet High Strength: Density 1000-1100 kg/m³; dry bending strength ≥ 18 MPa, impact resistance ≥ 5 kJ/m² (exceeds gypsum and fiber cement cladding).

Dimensional Stability: Low moisture movement (≤ 0.12%) – no expansion or contraction under temperature/humidity changes, ensuring long-term cladding flatness.

Workability: Can be sawn, drilled, or routed with standard tools – easy to install complex shapes (e.g., corner trims, curved facades).

4. Environmental Friendliness & Health Safety

Formaldehyde-Free: Zero VOC emissions, no asbestos, benzene, or heavy metals – complies with EU REACH, US CARB P2, and LEED green building standards.

Sustainable: Made from abundant natural minerals; 100% recyclable at end-of-life; low energy consumption during production (30% less than cement-based cladding).

5. Decorative Versatility

Surface Finishes: Sanded (smooth for painting), brushed (textured for industrial styles), or custom patterns (e.g., wood grain, stone texture) – reduces the need for additional decorative layers.

Color Adaptability: Compatible with water-based paints, architectural coatings, or thermal insulation coatings – supports personalized facade designs.

Preparation Work: Check that the construction site ground is flat and free of debris, and ensure waterproofing treatment is done well. Prepare necessary tools and materials such as cutting machines, electric drills, screwdrivers, special glue, and sealants. Meanwhile, confirm that the magnesium oxide boards are flat, undamaged, and their performance meets the requirements for resisting hurricanes.

Base Treatment: Inspect that the base layer is flat, dry, and free of oil stains, etc. Fill in any depressions and polish down any protrusions. If using the pasting method, apply a base treatment agent as required to enhance adhesion, and proceed with subsequent operations after it dries.

Measurement and Cutting: Measure the dimensions of the installation area, draw contour lines on the magnesium oxide board, and cut along the lines using a saw or cutting machine, keeping the cuts neat and free of burrs.

Installing Keels: In hurricane-resistant scenarios, the keels must be stable. The center spacing of vertical keels should be controlled within 450-600mm. Additional keels should be added at wall joints and on both sides of doors and windows; if the wall height exceeds 2440mm, supporting keels should also be installed at the joints of the boards.

Fixing the Boards: It is recommended to use boards with a thickness of 6mm or more. Fix the boards to the keels with 3.5×200mm countersunk screws, ensuring the screw heads are 0.5mm below the board surface. The center distance between screw installations is set to 150mm, about 10mm from the board edge, and approximately 30mm from the board corner.

Joint Treatment: Leave a 4-6mm gap between adjacent boards. Use 107 glue or strong adhesive to mix, apply it to the boards and gaps with a scraper, then paste and flatten with paper tape or mesh tape. For high-sealing requirements, special sealant can be applied.

Treatment of Special Areas: When tiling in damp areas, reduce the keel spacing to 400mm, and set an expansion joint every about 3.6 meters on the wall. For areas where heavy objects need to be hung, reinforce with wooden boards or keels.

Inspection and Acceptance: Use a level and a straightedge to check the flatness and verticality of the magnesium oxide boards. Test the stability of key parts or under simulated strong wind conditions, and promptly reinforce and adjust if there are any loose conditions.
