Overview
The MKH Class A1 MGO Fireproof Board is engineered as a high-performance, eco-friendly structural magnesium oxide board designed for premium wall partitions and ceiling systems.
The board integrates a multi-layer fiberglass mesh matrix with high-purity magnesium oxide formulas, delivering an uncombustible structural shield available in standard 1220×2440 mm dimensions with thicknesses ranging from 3 mm to 25 mm.
Engineered for global compliance, it provides structural stability and exceptional moisture resistance for high-humidity and fire-rated assemblies.
Key Features
- Class A1 Non-combustible fire rating for zero smoke and zero flame spread.
- Standard structural dimensions: 1220×2440 mm (Custom lengths and widths available upon engineering request).
- 100% Asbestos-free, non-toxic, and eco-friendly
- Excellent acoustic damping and thermal insulation performance for commercial and residential wall systems.

Recommended Capacity & Load-Bearing
- Ceiling Systems: 3–6 mm thickness recommended for lightweight suspended acoustic ceiling layouts.
- Interior Partitions: 9–12 mm thickness recommended for standard commercial drywall and steel-stud framing.
- Exterior Sheathing & Subflooring: 15–20 mm thickness recommended; ensure appropriate weather-barrier membranes are applied.
- Screwing & Fastening: Maintain >15 mm distance from edges; use structural self-tapping countersunk screws.
- For high-load wall-hanging systems, verify structural metal stud spacing (typical 400 mm / 600 mm centers) via onsite mockup tests.
Notes: Actual structural performance is subject to installation methodologies, framing configurations, and local building codes.
Extreme high-span ceiling systems may require engineered layout optimization. Always verify compliance with local project engineers.
Technical Details & Safety
- Utilize carbide-tipped or diamond-dusted sawing blades for clean, low-dust edge cutting during on-site fabrication.
- Position boards with a 2–3 mm expansion gap at joints; fill with approved flexible, fire-rated joint acrylic compounds.
- Avoid twisting or dropping boards horizontally during manual transport to prevent micro-cracking and edge chips.
- Wear regulatory dust masks (N95/P2 grade), safety goggles, and protective gloves during mechanical cutting and sanding.
- Do not install boards in continuously submerged or standing water zones; ensure proper structural ventilation.
- Store flat on raised pallets in dry, covered indoor environments; shield from direct moisture before final priming.
Applications
- Commercial High-Rises & Office Partitions: Fire-rated drywall separation zones requiring rigid EN 13501-1 certification.
- Residential Kitchens & Bathrooms: Moisture-resistant tile backer boards and fireproof ceiling underlayments.
- Industrial & Logistics Warehouses: Heavy-duty firewall enclosures, shaft liners, and escape route corridor cladding.
- Retrofit & Architectural Refurbishment: Lightweight structural upgrades to meet modern fire safety and green building standards.
Package & Accessories
- Standard Package: Heavy-duty exporting pallets with protective plastic wrapping and edge steel strapping.
- Optional Accessories: Grade 8.8 corrosion-resistant screws, alkali-resistant fiberglass joint tapes, fire-rated joint sealants.
