What Is a Magnesium Oxide Board (MGO Panel)?
A Magnesium Oxide (MGO) Board is a next-generation construction material designed to outperform conventional drywall, plywood, and cement boards in both interior and exterior applications.
Manufactured from a blend of mineral-based materials—including magnesium oxide, magnesium chloride, and reinforced fibers—these panels provide exceptional durability, fire resistance, and moisture protection.
MGO Boards are an excellent choice for architects, builders, and developers who prioritize sustainable and long-lasting building solutions.

Why Choose MGO Board?
Compared to traditional gypsum or fiber cement panels, MGO Boards offer superior performance, longevity, and design flexibility. They install easily with standard tools, integrate with most framing systems, and provide a smooth, paint-ready surface with minimal preparation.
As noted by Wikipedia’s Magnesium Oxide Wallboard reference, these panels are increasingly preferred for fire- and moisture-critical building applications.
