Magnesium oxide board is a new type of inorganic board. It can be regarded as an upgraded or differentiated alternative to traditional gypsum boards, fiber cement boards, calcium silicate boards, or OSB boards. It is widely used in building applications such as internal partition walls, suspended ceilings, flooring, fire-resistant boards,SIP boards and fire-resistant door core board.
What are the adhesion properties of MGO boards?
MGO boards feature exceptional adhesion performance, enabling them to bond seamlessly with a wide array of finishing materials such as paint, Portland cement stucco, synthetic stucco, wallpaper, stone, tiles and bricks. Their superior adhesion also makes them an ideal choice for Structural Insulated Panels (SIPs), Exterior Insulation and Finish Systems (EIFS), as well as interior wall systems that incorporate fabric substrates.
Is corrosion a concern for MGO boards?
MGO boards are inherently corrosion-resistant. Composed of magnesium oxide and inorganic materials, they do not contain metal components that are prone to rusting. This feature ensures stable performance even in humid or mildly corrosive environments, making them suitable for both interior and exterior applications without corrosion-related worries.
Why is the MGO board considered a carbon-negative product?
The MgO board is recognized as a carbon-negative product mainly due to its raw material extraction and production process. Its core component, magnesium oxide, is derived from the calcination of magnesite, a process that naturally captures and sequesters carbon dioxide. Additionally, the manufacturing of MgO boards adopts low-energy-consumption and low-emission technologies, minimizing carbon footprint during production. Over the full product lifecycle, the total amount of carbon dioxide absorbed and locked by the board exceeds the carbon emissions generated throughout its production, transportation, and application stages, thus achieving a carbon-negative profile.
Does the MGO board maintain dimensional stability under freeze-thaw cycles, thermal fluctuations and humidity variations?
The MGO board demonstrates excellent dimensional stability when subjected to freeze-thaw cycles, thermal changes and humidity fluctuations. Made from inorganic magnesium oxide as the core material, it contains no organic components that would cause swelling or shrinkage. Even after repeated cycles of freezing, thawing, heating and humidifying, the board only experiences negligible deformation, with no cracking, warping or delamination issues. This performance makes it ideal for outdoor applications and construction projects in areas with harsh climate conditions.
How does the service life of MGO -structured houses compare with that of brick houses?
Under proper construction and regular maintenance, MgO board-structured houses have a service life comparable to that of brick houses, generally reaching 50–70 years. As an inorganic material, MgO board is inherently resistant to corrosion, mold, and insect damage, and maintains excellent dimensional stability even in harsh environments like freeze-thaw cycles and high humidity. Unlike brick houses that may suffer from efflorescence, cracking, or structural damage due to long-term moisture accumulation, MgO board houses avoid such issues effectively. With standardized construction and routine upkeep, their durability can fully meet the service life requirements of residential and commercial buildings.
What are the standard and common sizes and thicknesses of Magnesium Oxide (MGO) Board?
Standard Sizes: •4 feet x 8 feet (1220mm x 2440mm) - This is the most common and readily available size. •4 feet x 10 feet(1220mm x 3050mm) •Other sizes like 3' x 6', 4' x 9', and 5' x 10' may also be available depending on the manufacturer. Standard Thicknesses: •Common Thickness Range:3mm, 6mm, 8mm, 9mm, 10mm, 12mm, 15mm, 18mm,20mm. •For Interior Walls: 6mm to 12mm are typically used. •For Exterior Sheathing or Flooring: 12mm to 18mm are recommended for higher strength requirements.
