Magnesium Oxide Board (MgO Board) is a high-performance, fire-resistant building material made from inorganic minerals. It is produced using a proprietary formulation of magnesium oxide (MgO), magnesium chloride (MgCl₂), perlite, fiberglass mesh, and mineral additives, resulting in a versatile, durable, non-combustible, and eco-friendly panel.
This integrated, rigid, and paper-free construction board delivers superior strength and stability compared to traditional materials such as gypsum, clay, wood, or paper-based panels. It enables faster, cleaner, and more efficient construction across a wide range of building applications.
MgO boards are ideal for both interior and exterior structures. They provide over 3 hours of fire resistance, ensuring enhanced building safety. The boards remain free from condensation and corrosion, making them particularly suitable for steel frame structures. When used as partition panels, MgO boards offer excellent waterproof performance, effectively protecting steel from oxidation and rust.
In addition, MgO boards are impervious to fire, water, and insects, and they do not support the growth of mold or mildew. They are non-toxic, non-flammable, non-combustible, and dimensionally stable, providing a long-lasting and sustainable solution for modern green construction.
MgO boards are manufactured using A-grade non-combustible materials certified by national authorities. They provide up to 4 hours of fire resistance and do not release harmful gases when exposed to flames, ensuring maximum safety for occupants.
These boards offer exceptional moisture-proof performance. Even when fully immersed in water, they maintain their structural integrity without swelling, warping, or deformation, making them ideal for humid or wet environments.
MgO boards deliver excellent acoustic performance—equivalent to a 95 mm insulated wall, a 12 mm gypsum board, or a 150 mm solid brick wall—effectively reducing noise transmission and improving indoor comfort.
With a thermal conductivity of 1.14 ㎡·K/W, MgO boards provide strong thermal insulation, helping maintain stable indoor temperatures and improving overall energy efficiency.
MgO boards are easy to handle, cut, and install, significantly reducing labor time and construction costs. Despite their lightweight structure and thinner profiles, they maintain high bending strength and support various machining and finishing methods.
