Magnesium Oxide (MgO) boards offer exceptional benefits in construction, primarily due to their low thermal conductivity. This characteristic makes them essential for building projects requiring heat resistance, efficient insulation, and enhanced safety.
Understanding Thermal Conductivity
Thermal conductivity is a material’s ability to conduct heat. It is a critical factor in construction as it determines how healthy materials can insulate and manage heat transfer within a building. Low thermal conductivity materials like MgO boards resist the passage of heat, making them effective at maintaining internal temperatures and reducing energy costs.
The Role of MgO Boards in Thermal Insulation
MgO boards have a thermal conductivity value of 0.038 W/mK, significantly lower than other commonly used construction materials like drywall (0.160 W/mK) and cement board (0.130 W/mK). This low thermal conductivity rating allows for superior building insulation properties, reducing heat transfer through walls, roofs, and floors. As a result, MgO boards contribute to making buildings more energy-efficient and comfortable.
Enhanced Fire Resistance with Low Thermal Conductivity
Besides their excellent insulation capabilities, the low thermal conductivity of MgO boards also enhances their fire resistance properties. Heat energy takes longer
Factors influencing thermal conductivity include:
Free Electron Availability
Temperature
Density
Moisture Content
Material Thickness
These structural and environmental traits impact how effectively a material allows or resists heat flow.
The Thermal Performance of MgO Boards
With a thermal conductivity coefficient of 0.216 W/m·K, MgO boards excel in heat insulation. They are resistant to heat, cold, and moisture, ensuring durability and performance across various climates. This makes MgO boards preferred for applications where thermal stability and fire resistance are priorities.
Feature | MgO Board | Calcium Silicate Board | Gypsum Board |
Density | 0.9–1.3 g/cm³ | 1.3–1.5 g/cm³ | 1.2–1.3 g/cm³ |
Impact Strength | ≥4.5 KJ | ≥3.5 KJ | ≤1 KJ |
Bending Strength | ≥20 MPa | ≥14 MPa | ≤9 MPa |
Thermal Conductivity | 0.64 W/m²·K | 0.53 W/m²·K | 0.61 W/m²·K |
Thermal Expansion | 2.6×10⁻⁷ mm/°C | 7.5×10⁻⁷ mm/°C | 6×10⁻⁷ mm/°C |
MgO boards stand out for their low density and high strength balance, combined with exceptional heat transfer resistance.
Advantages of Low Thermal Conductivity in MgO Boards
The low thermal conductivity of MgO boards results in a range of benefits for construction applications:
1. Efficient Insulation
MgO boards significantly reduce heat transfer between a building's interior and exterior. This enhances energy efficiency, minimizes heating and cooling costs, and provides a comfortable indoor environment, especially in extreme climates.
2. Thermal Stability
Their heat resistance ensures stability against temperature fluctuations, preventing thermal expansion and contraction, thereby enhancing buildings' structural integrity and longevity.
3. Fire Resistance
With low thermal conductivity, MgO boards provide excellent fire resistance, ensuring the safety of structures and occupants. Their ability to resist high temperatures minimizes damage during fire incidents.
4. Acoustic Insulation
MgO boards possess effective noise insulation properties, reducing noise pollution and ensuring quieter indoor spaces—a crucial feature for areas such as hospitals, offices, and educational institutions.
5. Energy Efficiency and Sustainability
MgO boards are an environmentally sustainable building material. Their insulating properties and energy efficiency reduce the overall carbon footprint of structures, aligning with modern green-building initiatives.
Applications of MgO Boards
The versatility of MgO boards makes them suitable for a wide range of applications:
Ceilings
Flooring and Sub-flooring
Exterior Wall Sheathing Panels
Under Roofing
Tile Backing
Their thermal and fire-resistant properties make MgO boards ideal for use in hospitals, schools, offices, and high-safety areas.
