Magnesium Sheathing Board
Magnesium sheathing board is a non-combustible construction material specifically designed for wall and floor sheathing applications. Formulated with magnesium oxide, magnesium sulfate, and complementary fillers as its core components, it acts as a versatile and durable alternative to traditional sheathing materials like plywood or gypsum board. Its inherent advantages include reliable fire resistance, effective mold and mildew inhibition, and improved impact strength—rendering it well-suited for high-demand construction scenarios.
