Product Introduction
Fireproof Magnesium Oxide Ceiling Board
Fireproof Magnesium Oxide Ceiling Board (also known as MgO Ceiling Board or Magnesia Ceiling Panel) is a high-performance, non-combustible building material specifically designed for ceiling applications, offering exceptional fire resistance, moisture protection, and durability compared to traditional ceiling materials like gypsum board. This innovative board has become a preferred choice for both residential and commercial construction projects where safety, longevity, and environmental performance are priorities.
MgO ceiling board is a composite material manufactured using a ternary system of magnesium oxide (MgO), magnesium chloride (MgCl₂) or magnesium sulfate (MgSO₄), and water, reinforced with alkali-resistant fiberglass mesh and filled with lightweight, non-combustible materials such as perlite or sawdust. The chemical reaction between MgO and the magnesium salt creates a stable, crystalline structure that delivers outstanding physical properties.
Modern formulations often use magnesium sulfate instead of magnesium chloride to eliminate potential corrosion issues and improve long-term stability. The boards are available in various surface finishes, from plain to textured or pre-decorated options, making them versatile for different design aesthetics.

Resists deformation even after 72 hours of continuous water immersion
Suitable for both interior and semi-exterior applications
3. Exceptional Durability & Strength
Lightweight yet strong (density: 0.8-1.1 g/cm³), approximately 20-30% lighter than cement boards
High flexural strength (15 MPa+), impact resistance, and load-bearing capacity
Dimensional stability across temperature fluctuations (-20°C to 80°C)
Resistant to pests, rodents, and microbial growth
Long service life (50+ years) with minimal maintenance requirements
4. Environmentally Friendly & Healthy
100% free of asbestos, formaldehyde, heavy metals, and other harmful substances
Low VOC emissions, contributing to better indoor air quality
Made from abundant, naturally occurring minerals, reducing reliance on non-renewable resources
Recyclable at the end of its service life
5. Easy Installation & Versatility
Lightweight design simplifies handling, cutting (with standard tools), and installation
Compatible with standard ceiling systems (suspended, direct-mount, or drop ceiling)
Can be painted, wallpapered, tiled, or finished with various decorative materials
Available in custom sizes, thicknesses, and edge profiles to meet specific project requirements
6. Additional Performance Advantages
Excellent sound insulation properties (sound loss of 1.14 m²K/W for 6mm boards)
Thermal insulation capabilities that contribute to energy efficiency
Resistant to sagging under normal ceiling loads
Cost-effective over the long term due to low maintenance and replacement costs
Magnesium oxide wall board is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products.
Magnesium Oxide Wall Panels are cementitious substrate products reinforced with magnesium oxide fibre matting.
Fire resistant magnesium oxide wallboard is a new type of refractory material. It is widely used primarily as a wallboard alternative to conventional gypsum-based drywall and plywood.
It is non combustible and fire rated Class A1. With options for up to a 2 hour fire resistance, MgO Board offers an innovative passive fire protection alternative for your construction projects.
MgO board has very good fire performance. It does not spread flames or smoke. It is noncombustible and fire-rated A1, which helps protect homeowners, tenants and building occupants while mitigating damage and loss.
Magnesium oxide wall board is made of magnesium oxide, magnesium sulfate or magnesium chloride, glass fiber mesh, perlite and wood fiber.
It is an upgraded product of fireboard. A properly constructed assembly with our MgO fireproof wall board can achieve a 3-hour fireproof rating.
Fire Resistant Internal Wall Board
Our Fire Resistant Internal Wall Board is a fiberglass reinforced magnesium oxide cement board. It can be used to replace traditional gypsum drywall for wall and ceiling finishes and sheathing.
Fireproof Exterior Wall Panels
Magnesium oxide board is a new type of fire-resistant building material. The main raw materials are magnesium oxide, magnesium chloride/sulfate and perlite.

Manufacturing Process
Raw Material Preparation: High-purity active MgO, magnesium salt (MgCl₂/MgSO₄), water, and additives are precisely measured and mixed
Slurry Formation: The ingredients are blended to create a homogeneous slurry with optimal viscosity
Board Formation: The slurry is spread onto a moving conveyor belt, reinforced with alkali-resistant fiberglass mesh, and covered with another layer of slurry
Curing Process: The boards undergo controlled curing (24-48 hours) to allow the chemical reaction to complete and form a stable structure
Drying: Boards are dried in temperature-controlled ovens to achieve the desired moisture content (≤8%)
Finishing: Surface treatment (sanding, coating, or decorating) and cutting to standard or custom sizes
Quality Control: Rigorous testing for fire resistance, strength, moisture content, and dimensional accuracy before packaging
Installation Guidelines
Preparation
Choose appropriate thickness (6mm-12mm recommended for ceilings) and ensure all materials meet specifications
Prepare ceiling framework (light gauge steel 龙骨 or wooden battens) with proper spacing (≤600mm centers)
Use 316 stainless steel fasteners to prevent corrosion (critical for long-term performance)
Installation Steps
Cutting: Use a circular saw or jigsaw with a carbide-tipped blade for clean, precise cuts
Fixing:
Fasten perimeter of boards 6" apart and center fasteners 12" apart
Keep fasteners at least 4" away from corners to prevent cracking
Drive screws slightly below the surface without breaking the fiberglass mesh
Joint Treatment: Fill joints with MgO-compatible joint compound and embed fiberglass tape for reinforcement
Finishing: Sand surface smooth, prime, and apply decorative finish as desired
Key Installation Tips
Leave 2mm expansion gaps between boards to accommodate temperature changes
Ensure proper ventilation during installation and curing of joint compounds
Follow manufacturer's recommendations for specific applications (e.g., wet areas may require additional waterproofing)
