Product Introduction
Fire resistant MgO boardAdvantages of Fire resistant MgO board
Magnesium oxide board is mainly made from magnesium oxide (MgO), magnesium chloride (MgCl₂) or magnesium sulfate(MgSo4) and other substances as the main raw materials through a series of processing techniques. Usually, an appropriate amount of fillers, reinforcing fibers and so on will be added. Through processes such as stirring and mixing, molding and curing, it is solidified to form a board with certain strength and performance, and then it can be used as an exterior wall cladding.
Advantages of Fire resistant MgO board
1. Fire Resistance:
As mentioned before, it belongs to Class A1 non-combustible materials, and its fire resistance rating can reach a certain duration. In the event of a fire, it can effectively prevent the rapid spread of the fire, buying precious time for personnel evacuation and fire rescue, protecting the safety of the building structure and internal facilities. Its good fire resistance stems from the fact that it will not burn like combustible materials under high temperatures, and its own structure can still maintain a certain degree of integrity, playing a role in blocking the spread of heat and flames.
2. Waterproof and Moisture-proof Performance:
After reasonable formulation and process treatment, its internal structure is compact and has a low water absorption rate. It can be used for a long time in humid environments without problems such as moisture absorption, deformation, or mildew. For example, when used in basements, bathrooms, kitchens, and other places with high humidity, it can still maintain stable performance and appearance and ensure normal usage functions.
3. Mechanical Properties:
It has relatively high compressive and flexural strengths and can withstand certain external forces. For example, when used as an indoor partition wall, it is not easily damaged even when subjected to daily collisions, squeezes, etc. At the same time, the addition of reinforcing materials such as glass fibers further improves its tensile properties, making it more reliable in structural applications.
4. Sound Insulation and Heat Insulation Performance:
The internal pore structure and the addition of materials with heat insulation and sound insulation effects, such as perlite, enable it to effectively block the transmission of sound, reduce external noise interference, and create a relatively quiet indoor environment. It can also impede the transfer of heat, contributing to the thermal insulation of buildings and helping to reduce energy consumption and achieve energy-saving effects.
5. Environmental Protection Performance:
During production and use, it does not release harmful volatile organic compounds such as formaldehyde and benzene, making it a green and environmentally friendly material that will not pollute the indoor air quality and is friendly to the health of residents and users, meeting the current requirements for environmentally friendly decoration materials.
6. Corrosion Resistance:
It has good tolerance to common chemical substances such as acids and alkalis. When used in some industrial environments, areas with risks of chemical pollution, or special places, it can still maintain stable performance and is not easily corroded and damaged, prolonging its service life.
Magnesium oxide wall 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 Wall Panels are cementitious substrate products reinforced with magnesium oxide fibre matting.
Fire resistant magnesium oxide wallboard is a new type of refractory material. It is widely used primarily as a wallboard alternative to conventional gypsum-based drywall and plywood.
It is non combustible and fire rated Class A1. With options for up to a 2 hour fire resistance, MgO Board offers an innovative passive fire protection alternative for your construction projects.
MgO board has very good fire performance. It does not spread flames or smoke. It is noncombustible and fire-rated A1, which helps protect homeowners, tenants and building occupants while mitigating damage and loss.
Magnesium oxide wall board is made of magnesium oxide, magnesium sulfate or magnesium chloride, glass fiber mesh, perlite and wood fiber.
It is an upgraded product of fireboard. A properly constructed assembly with our MgO fireproof wall board can achieve a 3-hour fireproof rating.

Manufacturing Process of Magnesium Oxide Board Exterior Wall Cladding




Magnesia board is mainly made from magnesium oxide (MgO), magnesium chloride (MgCl₂), etc. as the main raw materials through a series of processing techniques. Appropriate fillers and reinforcing fibers are usually added. After mixing, molding, curing and other processes, it solidifies into boards with certain strength and performance, which can then be used as exterior wall cladding.
What is Magnesium Oxide Board Exterior Wall Cladding Used for
Various Civil Buildings: When used on the exterior walls of residential buildings, apartments and other civil buildings, it can not only enhance the aesthetics of the building but also strengthen the protective performance of the exterior wall, ensuring the safety, comfort and energy efficiency of the living environment.
Public Building Field: For public buildings such as schools, hospitals, libraries, museums, etc., the fireproof, environmental protection, weather resistance and other characteristics of magnesia board exterior wall cladding can well meet the multiple requirements of these places for building safety, aesthetics and functions.
Industrial Building Aspect: For the exterior walls of some industrial plants and warehouses with certain requirements for fire protection and moisture-proof, it is also an ideal choice of cladding material.
Magnesium Oxide Board Exterior Wall Cladding vs. Other Materials
It's safe to say that magnesium oxide boards have several advantages over other construction materials, based on the benefits previously mentioned.
Gypsum
Although both gypsum and magnesium oxide boards are eco-friendly, the former poses more harm to people because its fly ash releases toxins when cut.
Portland Cement
Portland cement lacks water-resistant and fire-suppressing capabilities. Plus, MgO leaves a smaller carbon footprint compared to cement. And although Portland cement is recognizably strong, MgO has a higher rating on impact strength even though it is considerably lighter in weight.
Plywood
MgO is undoubtedly safer than plywood as a construction material. Plywood is not flame resistant and could quickly spread fire it is not water resistant, making it susceptible to moisture that could grow mould and vulnerable to water damage.
Oriented Strand Board (OSB)
When it comes to safety, MgO ranks higher than OSB. The OSB releases formaldehyde, a dangerous toxin. It is not fire resistant nor is it resistant to moisture and termites.
