Magnesium oxide (mgo) board 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. Fire Resistance limit of fireproof MgO board: 9mm Wellyoung MgO board could be applied for >= 120mins fireproof lightweight partition wall; 12mm Wellyoung MgO board could be applied for >= 180mins fireproof lightweight partition wall.
