Features of magnesium oxide board: WATER RESISTANCE Magnesium oxide inherently has very low water absorption and any moisture is naturally expelled. There is also no deterioration from freeze/thaw cycles. MOLD RESISTANCE Since MgO board will not hold moisture, and since there is nothing within the product to act as a food source, the product will not support mold growth. The same applies to insects. VERSATILITY Whether used on its own as a sheathing, wallboard or underlayment, or in conjunction with other building materials such as plywood, OSB or drywall, it can add tremendous value. MgO has an unlimited number of uses. Fire retardant plywood and OSB, demising walls and insulated exterior wall panels are some of the initial products that offer enormous performance-to-value propositions. FIRE RESISTANCE Magnesium oxide boards are essentially non combustible, with a flame spread of ZERO and a smoke development of ZERO. These properties make it highly effective either standing alone as a sheathing / underlayment or when laminated to other materials. IMPACT RESISTANCE While having the appearance and texture of cement or stone, magnesium oxide board has excellent flexture and tensile properties. All of these properties combine to produce a board with vastly superior impact resistance.
