Their smooth surface is perfect for interior walls, whether painted or finished, providing a polished appearance. They also serve as a waterproof barrier on the outside, protecting against moisture and severe weather conditions, and enhancing the structure’s aesthetics.

3. Ceiling Linings
MGO boards can be integrated into ceilings to provide a polished and clean appearance. They are an excellent choice for suspended ceiling systems, offering a sleek and contemporary look while providing fire-resistant properties, making them suitable for any room.

4. Decorating Boards
MGO boards are a stunning choice for interior walls and ceilings, offering a range of design possibilities. They are graded fireproof, moisture-resistant, impact-resistant, and provide thermal insulation. Their appealing appearance makes them suitable for decorative applications, cladding, or ornamental wall panels.

5. Partition Walls
MGO boards are commonly used as partition walls due to their durability and fire resistance. They are suitable for constructing walls, ceilings, partitions, and doors. The lightweight design of MGO boards makes them reliable for internal wall barriers, and they can be easily installed on metal or wood frames.

6. Flooring Foundations
MGO boards are an excellent choice for flooring foundations, serving as a solid subfloor material. They can be used for raised floors, offering better cable management and air circulation, resulting in a stable and long-lasting construction project.

7. Tile Backer Boards
MGO boards are the ideal choice for damp areas, offering a strong and moisture-free surface for tiling. Their high compressive strengths ensure they stay in place, providing a reliable foundation for tiles.

In summary, MGO boards and panels are a versatile and durable building material with a wide range of applications, making them an excellent choice for any construction project.

Moisture Resistance
Magnesium oxide boards exhibit a remarkable surface moisture absorption rate of 0.34%, starkly contrasting the 3% absorption rate of gypsum boards. This significant difference highlights the magnesium boards’ superior resistance to water and moisture. Gypsum boards, conversely, are highly vulnerable to water damage due to their high water absorption capacity, which can lead to board deterioration even from minimal water exposure.

Fire Resistance
Magnesium Oxide and Gypsum boards are both non-combustible, but magnesium oxide boards hold a distinct advantage. With a thickness of over 3 mm, magnesium oxide boards meet fire safety standards, whereas gypsum boards require a thickness of up to 12 mm to meet the same standards. The fire resistance of magnesium oxide boards is exemplified by their exceptional performance in rigorous tests, such as the ASTM E136-16A test, where they remained unaltered at 750°C.

Density
Magnesium oxide boards boast a low density of 0.85–1.2 g/cm3, contributing to their lightweight nature. The inclusion of glass fiber in these boards provides them with both strength and reduced weight. In comparison, gypsum boards have a density range of 1.2-1.3 g/cm3, necessitating higher density to match the strength of magnesium oxide boards at a lower density.

Impact Strength
MgO boards exhibit a high impact strength of 4.5 kilo Joules or greater, thanks to their fiberglass mesh composition. This attribute is crucial for withstanding sudden and intense impacts without compromising their form. Gypsum boards, containing paper fibers, have an impact strength of only 1 kilo Joule, making them more susceptible to cracks, breaks, and deformation.

Bending Strength
Bending strength, also known as flexural strength, refers to a material’s ability to withstand loads without bending or deforming. Magnesium oxide boards offer an impressive bending strength of 18-27 MPa, which is a result of their fibrous structure and fiberglass content. Gypsum boards, however, have a lower bending strength of 5.6 MPa or less, primarily due to their paper fiber composition.

Environmental Impact
Both magnesium oxide and gypsum boards are environmentally friendly, as they do not emit toxic chemicals. The manufacturing process of magnesium oxide boards, however, consumes less fuel than that of gypsum boards, making them not only cost-effective but also more environmentally friendly.

MgO boards are known for their high fire resistance and can withstand exposure to high temperatures without bursting into flames. They are often used in walls and ceilings that need to be fire-rated, which means that they are part of a system designed to keep fire from spreading.

MgO Boards Are Fire-Resistant

MgO boards are constructed from magnesium oxide, an inorganic substance that is inherently fire-resistant. Unlike drywalls, which are typically made from wood and other flammable materials, MgO boards do not contain any combustible substances. This inherent fire resistance significantly reduces the risk of the boards catching fire and contributing to the spread of flames.

MgO Boards Withstand High Heat

In the face of a fire, MgO boards prove to be a resilient choice in the construction industry. While standard drywalls and other materials quickly succumb to heat and collapse, MgO boards remain unaffected. Their composition and exceptional endurance ensure they do not melt, burn, or lose structural integrity. These boards are particularly suitable for protecting buildings from extreme heat, with the ability to withstand temperatures as high as 1,472°F (800°C). When used in pre-built walls or panels, MgO boards can even withstand an open flame for an impressive 4 hours.

MgO Boards Are Non-Toxic

One of the key advantages of MgO boards is their lack of toxicity when exposed to high heat. Unlike organic materials that can ignite and release harmful fumes, MgO boards are devoid of such components. This means that in the event of a fire, they do not produce smoke or fumes that can be hazardous to health. The absence of fumes reduces the risk of smoke inhalation, which is crucial for maintaining consciousness and safety during a fire emergency. Choosing materials like MgO boards helps protect individuals from the severe consequences of smoke inhalation.
