Main Features of Magnesium Oxide Board
1. Excellent Fire Resistance
Magnesium Oxide Boards offer outstanding A1-grade fire resistance, capable of withstanding extreme temperatures without emitting any toxic smoke or harmful gases. They are ideal for projects requiring reliable fireproof performance and safety compliance.
2. Superior Moisture and Water Resistance
With excellent moisture-proof and waterproof properties, MgO boards prevent mold growth, warping, or deterioration even in high-humidity areas such as bathrooms, kitchens, or basements.
3. High Impact Strength
These boards deliver strong impact resistance and maintain integrity under pressure or moderate impacts, ensuring long-term durability in both residential and commercial applications.
4. Effective Thermal Insulation
MgO boards provide efficient thermal insulation, helping regulate indoor temperature and improve building energy efficiency, even though they are not primarily insulation materials.
5. Reliable Sound Insulation
Designed for better acoustic performance, MgO boards help reduce noise transmission between rooms or from external environments, creating a more comfortable and quiet indoor space.
6. Excellent Dimensional Stability
Thanks to their stable inorganic composition, these boards resist expansion, contraction, or deformation under changing temperature and humidity conditions, ensuring consistent performance over time.
