Magnesium Wall board for Sheathing
Magnesium wall boards for sheathing, also known as magnesium oxide sheathing, are a strong, fireproof, and weather-resistant building material that can be used for sheathing, providing structural support for exterior walls and roofs. They are an innovative alternative to traditional materials like OSB or plywood, offering advantages such as high flame and impact resistance, moisture and mold resistance, and good sound control.

Advantages:
- Fire resistance: MGO boards are non-combustible and offer a high degree of fire resistance, which can be important for fire-rated wall assemblies.
- Strength and durability: They have high strength and impact resistance, and are resistant to mold, mildew, termites, and corrosion.
- Moisture and water resistance: Modern versions, which use magnesium sulfate instead of some wood components, are more moisture-resistant and suitable for applications in wet conditions.
- Sound control: MGO boards provide good sound control properties.
- Eco-friendly: MGO boards can be considered low-carbon due to the lower energy used in production and their ability to absorb atmospheric CO2 during curing.
