In Which Scenarios Is Magnesium Oxide Board Primarily Used

Magnesium oxide board (magnesium silicate board) is an A-class non-combustible inorganic panel made of magnesium oxide and magnesium chloride as the base material. It features moisture and mold resistance, soundproofing, thermal insulation, strong processability, and formaldehyde-free properties. It can be sawn, nailed, and glued, adapting to various construction techniques. As a superior alternative to gypsum boards and cement boards, it is widely used in residential, commercial, and industrial settings both indoors and outdoors. Key application scenarios include the following:

It is the mainstream material for interior partition walls and suspended ceilings, particularly suitable for residential kitchens and bathrooms, basements, and high-humidity coastal areas. It addresses the mold and deformation issues of traditional panel materials and is also used for spatial partitioning in apartments, office buildings, and hotels, typically installed with 6-12mm thickness in conjunction with light steel studs. As a critical fire safety material, its Class A non-combustible properties make it ideal for fireproof partition walls and wall edge cladding in densely populated spaces such as shopping malls and cinemas, as well as industrial plants and power distribution rooms. It can also be wrapped around steel and wood structures to enhance fire resistance limits, forming a complete fire protection system when paired with fire-resistant rock wool.

In industrial settings, the 12-18mm thickened version is used for enclosing walls in chemical plants and generator rooms, offering both impact resistance and sound insulation. It can also serve as the insulation base layer for villas and prefabricated housing, becoming suitable for outdoor use after treatments like fluorocarbon paint or stone-like paint for UV resistance and waterproofing. Additionally, it can be processed into fireproof door cores and furniture back panels, meeting comprehensive requirements such as environmental friendliness, easy cleaning, and fire resistance in places like hospitals, schools, and food processing plants. It is also a commonly used panel material for temporary construction in exhibition halls and booths.
