Magnesium Oxide Board (or MgO Board) is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products. Magnesium Oxide Board is virtually impervious to fire, water, insects; does not feed mold or mildew; is non-toxic, non- flammable and non-combustible; is durable, maintains its dimensional stability-even when wet; and, has exceptional bonding surface. Magnesium Oxide Board is a mineral based green builder product. And it is homogeneous-no de-lamination. Benefits & Advantages: Non-Toxic material safe to cut Resistance to fire, moisture, and wood boring insects Lightweight easy to nail & screw ASTM & ANSI tested Less energy required to install Long lasting materials reducing repair and replacement costs No silica-based Portland cement Post-consumer recycled content Silica/asbestos-Free Advanced Magnesium cement replaces ordinary Portland cement Can be used in the place of traditional drywall or cement boards. No special tools required. Solid construction no laminations Available in colors. Applications: In many applications, MgO boards can be used in the same ways as gypsum and Portland cement sheathings. The substitution is not fully direct in terms of sheet thicknesses, fastening methods and joint treatments, but is very similar. This makes MgO board an easy product to use.The possible uses of MgO board are vast, and some of them include: Firewalls.Partitions.Structural sheathing for wood or metal stud walls. Shower stall tile backer board. Facings for structural panels engineered to use MgO as the facing. Shaft liners. Ceilings. Soffits Fascia. Substrates for coatings and insulated systems (such as Direct-Applied Finish Systems, EIFS,and stucco). Size:1220 x2440/2745/3050mm Thickness:3-20mm
