In an era where building safety and sustainability are non-negotiable, traditional materials like gypsum and plywood are being pushed to their limits. Enter MagMatrix MgO Board—the high-performance, magnesium sulfate-based solution that is redefining structural integrity.
Whether you are looking for superior fire resistance or a mold-proof basement solution, here is everything you need to know about why MagMatrix is the industry leader in Magnesium Oxide (MgO) technology.
What is MagMatrix MgO Board?
MagMatrix is a specialized Magnesium Oxide board that utilizes a Basic Magnesium Sulfate (BMS) chemistry. Unlike cheaper MgO boards that use chloride (which can cause "crying" and metal corrosion), MagMatrix is 100% chloride-free. This makes it safe for use with light-gauge steel framing and high-humidity environments.
Key Performance Advantages
1. A1 Non-Combustible Fire Rating
Fire safety is the primary reason architects specify MagMatrix. Our boards are tested to withstand temperatures exceeding 1200 Celsius degree and it is A1 fire rated wall panels for commercial construction.
Zero Flame Spread: Does not contribute fuel to a fire.
No Toxic Smoke: Unlike PVC or treated wood, it releases no harmful gases.
Certified Protection: Ideal for 1, 2, and 4-hour fire-rated wall assemblies.
2. Total Moisture & Mold Resistance
Traditional drywall acts like a sponge, leading to structural rot and black mold. MagMatrix is dimensionally stable. Even if submerged in water, it will not swell, warp, or delaminate. Because it is an inorganic mineral, mold simply cannot grow on it. And it is one of the best molds resistant board for drywall alternative for basements.
3. Extreme Impact & Structural Strength
MagMatrix "Perseverance" boards are reinforced with multi-layers of high-tensile fiberglass mesh. And it is Chloride-free magnesium sulfate MgO board for steel studs.
This gives them the structural capacity to be used as:
Subflooring for modular builds.
Impact-resistant walls in hospitals and schools.
Exterior sheathing for high-wind zones.
4. Health & Eco-Sustainability
MagMatrix is a "breathable" building material that contributes to healthier indoor air quality (IAQ).
Carbon Neutral: MgO boards absorb Co2 during the curing process.
Non-Toxic: 100% free of asbestos, formaldehyde, and crystalline silica.
MagMatrix vs. The Competition
Feature | MagMatrix (Sulfate) | Standard MgO (Chloride) | Fiber Cement | Gypsum (Drywall) |
Corrosion Risk | None | High | Low | Medium |
Fire Rating | A1 (Best) | A1 | A1/A2 | Class A |
Water Stability | Excellent | Good | Moderate | Poor |
Impact Strength | High | Medium | High | Low |
Common Applications
Interior Fire Walls: For high-rise residential and commercial units.
Tile Backer Board: The perfect waterproof substrate for luxury bathrooms.
SIPs (Structural Insulated Panels): Used as the skin for energy-efficient modular homes.
Acoustic Insulation: Excellent sound-dampening properties for recording studios and cinemas.
Technical Specification Comparison: MagMatrix vs. Traditional Materials
Feature | MagMatrix MgO (Sulfate) | Traditional Drywall (Gypsum) | Fiber Cement Board |
Core Material | Magnesium Sulfate (Chloride-Free) | Gypsum / Paper Faced | Portland Cement / Sand |
Density | 1100-1250kg/m3 | 600 - 800kg/m3 | 1300 - 1500kg/m3 |
Fire Rating | Class A1 (Non-Combustible) | Class A (Combustible paper) | Class A1 (Non-Combustible) |
Bending Strength | 22-30Mpa | 10-12Mpa | 7-13Mpa |
Impact Strength | High (More than 38Mpa) | Low (Less than 1Mpa) | Moderate (8-10Mpa) |
Moisture Effect | Dimensionally Stable | Swells, Warps, Molds | Stable but Heavy |
Corrosion Risk | Zero (Sulfate Formula) | Low | Low |
Sustainability | Carbon Neutral / Recyclable | High Energy Production | High Carbon Footprint |
Standard MagMatrix Dimensions
To help with your project planning, MagMatrix boards are available in these common sizes:
Thickness Options: 6mm / 10mm / 12mm / 16mm /19mm / 20mm / 30mm
Standard Sheet Size: 1220mm x 2440mm / 1220mm x 3050mm
Custom Lengths: Available up to 3050mm
Why These Numbers Matter for Your Build
For Contractors: The high Bending Strength (22-30Mpa) means fewer snapped boards during transport and installation compared to brittle cement boards.
For Architects: The A1 Fire Rating allows you to specify a single layer of MagMatrix where you might otherwise need double-layered Type X gypsum to meet code.
For Developers: The Sulfate Chemistry is the "secret sauce." It ensures the board won't "cry" (leach moisture) or corrode the steel fasteners holding the building together.
Conclusion: Build Better with MagMatrix
If your project demands the highest standards of safety, durability, and environmental responsibility, MagMatrix is the clear choice. It replaces multiple products—drywall, cement board, and sheathing—with one superior, fire-rated panel.
