Magnesium Oxide Board: The Sustainable and Fire-Resistant Building Solution

In the evolving landscape of construction materials, Magnesium Oxide Board (MgO Board) has emerged as a versatile, high-performance alternative to traditional options like gypsum drywall and cement board. Composed primarily of magnesium oxide derived from magnesium-rich minerals, this innovative panel integrates reinforcing materials such as fiberglass mesh or organic fibers to create a robust and eco-friendly building solution.

Key Advantages of Magnesium Oxide Board:

1. Exceptional Fire Resistance
   With a Class A fire rating, MgO board is inherently non-combustible. It can withstand high temperatures without releasing toxic fumes, making it ideal for firewalls, elevator shafts, and residential safe rooms.
2. Moisture and Mold Resistance
   Unlike gypsum-based products, MgO boards resist water absorption and inhibit mold growth—critical for bathrooms, kitchens, basements, and humid climates.
3. Environmental Sustainability
   Made from abundant natural minerals and often free of formaldehyde/asbestos, MgO boards align with green building standards (e.g., LEED). Their production generates lower carbon emissions compared to cement-based materials.
4. Structural Durability
   High flexural and impact strength ensures longevity in demanding applications, from exterior sheathing to interior partitions.

Common Applications:

· Interior wall and ceiling systems
· Exterior insulation finishing systems (EIFS)
· Substrate for tiling and flooring
· Fire-rated assemblies in commercial/industrial projects
