Magnesium oxide (MgO) boards are a type of building material that has gained popularity for various construction applications, including exterior walls. Here are some key points to consider when using MgO boards for exterior walls:

  • Material Composition:

    • MgO boards are composed of magnesium oxide, a mineral-based material, and other additives such as fiberglass mesh. This combination provides strength, fire resistance, and durability.
  • Advantages:

    • Fire Resistance: MgO boards are known for their excellent fire resistance, making them a suitable choice for exterior walls where fire safety is a concern.
    • Mold Resistance: MgO boards are resistant to mold and mildew, contributing to a healthier indoor environment.
    • Durability: MgO boards are durable and resistant to weathering, which makes them suitable for exterior applications.
    • Water Resistance: While MgO boards are more water-resistant than traditional drywall, they are not entirely waterproof. It's essential to follow proper installation procedures and use appropriate sealants to enhance water resistance.
  • Installation:

    • MgO boards are typically installed using similar techniques as drywall, such as screwing or nailing them to the framing. It's crucial to follow the manufacturer's guidelines and recommendations for installation.
    • Proper sealing and flashing are essential to prevent water infiltration.
  • Finishing:

    • MgO boards can be finished with various coatings, such as paint or stucco, to achieve the desired appearance. It's important to use coatings suitable for exterior applications.
  • Cost:

    • MgO boards may be more expensive than traditional gypsum-based drywall, but their durability and performance characteristics can make them cost-effective in the long run, especially in exterior applications where additional strength and fire resistance are crucial.
  • Thermal Performance:

    • MgO boards have moderate thermal insulation properties. For enhanced insulation, additional materials may be needed in the wall assembly.
  • Supplier and Product Quality:

    • Choose reputable suppliers and ensure that the MgO boards meet the required standards and specifications for your specific application.

It's essential to consult with building professionals, such as architects and contractors, and follow local building codes and regulations when using MgO boards for exterior walls. Additionally, manufacturers' guidelines and recommendations should be strictly adhered to during installation to ensure optimal performance and longevity.
