MgO Board Sheathing
MgO (magnesium oxide) board sheathing is a non-combustible construction material engineered for wall and floor applications. Composed primarily of magnesium oxide, magnesium sulfate, and supplementary fillers, it serves as a versatile, long-lasting substitute for conventional sheathing options such as plywood or gypsum board. Key benefits include inherent fire resistance, mold/mildew prevention, and enhanced impact durability—making it ideal for demanding construction environments.
