A Magnesium Oxide (MgO) board is a versatile building material made from mineral cement, specifically magnesium oxide. Manufactured in controlled factory settings, MgO boards are widely used for applications such as fascias, soffits, tile backers, wall and ceiling linings, underlayment, and more. Known for their excellent durability and resistance to fire, mold, and weather, MgO boards are above traditional cement boards or drywall due to their enhanced properties.
Though primarily manufactured in Asia, MgO board usage is growing in the USA as the construction industry recognizes its numerous advantages.
The Historical Roots of MgO
Magnesium oxide has been utilized for centuries, dating back to the construction of the Pyramids, where it was a key ingredient in masonry mortar. While its use as sheathing panels is relatively new in North America, MgO boards have long been trusted in the Middle East and Asia for large-scale projects like fire-rated walls and partitions.
MgO boards come in various thicknesses (¼ inch to 1 inch) and sheet sizes, making them adaptable for different construction needs.
Applications of MgO Boards
MgO boards are valued for their versatility and are used across a wide range of applications, including:
Ceilings
Facings for structural panels
Fascias
Firewalls and partitions
Shaft liners
Soffits
Structural sheathing for wood or metal stud walls
Substrates for insulated systems and coatings
Tile backer boards, especially for shower stalls
These boards perform similarly to Portland cement and gypsum sheathings, although the thickness, fastening methods, and treatment of joints may vary.
Comparing MgO Boards to Portland Cement Boards—What Stands Out?
While MgO boards share some characteristics with Portland cement boards, they offer notable distinctions:
Superior Water Resistance: Unlike drywall, MgO boards can absorb water without compromising performance, making them ideal for high-moisture areas such as bathrooms and showers.
Flexibility: MgO boards are less brittle and more flexible than Portland cement boards. They can even be warped to create gentle curves for unique design requirements.
Durability: MgO boards are sturdier than drywall and exhibit great longevity, resistant to mold, fire, and weather impacts.
Like traditional boards, MgO boards can be scored and snapped or cut with power tools, ensuring ease of installation while offering superior performance.
