Difference Between Magnesium Oxide Board And Calcium Silicate Board

Magnesium Oxide (MgO) Board and Calcium Silicate Board are both types of sheathing used in construction for a variety of applications. They share some similarities, such as being non-combustible and resistant to moisture, but they also have some key differences:


1. Material Composition: As their names suggest, the MgO board is primarily made from magnesium oxide, while the Calcium Silicate board is made mainly from calcium silicate.


2. Fire Resistance: Both materials are non-combustible and have excellent fire resistance. However, MgO board is often cited as having superior fire resistance compared to Calcium Silicate board.


3. Water Resistance: Both boards are water-resistant and, therefore, suitable for use in damp environments or exterior applications. However, MgO board is often considered more water-resistant than Calcium Silicate board.


4. Impact Resistance: MgO boards generally have higher impact resistance, making them more durable under physical stress.


5. Flexibility: MgO board is generally more flexible than Calcium Silicate board, making it more versatile in specific applications.


6. Thermal Conductivity: Calcium Silicate board has a low thermal conductivity, making it a good choice for insulation purposes. MgO boards, while also having relatively low thermal conductivity, may not perform as well as Calcium Silicate boards in this regard.


7. Ease of Installation**: Both boards can be cut and installed using standard carpentry tools. However, some users find MgO boards easier to install because of their lighter weight and flexibility.


8. Environmental Impact: MgO boards are often cited as more environmentally friendly due to the lower CO2 emissions during production.


In conclusion, the choice between MgO and Calcium Silicate board will depend on your project's specific requirements, such as the need for fire resistance, water resistance, impact resistance, thermal insulation, and environmental considerations.






Calcium Silicate Board disadvantages


Calcium Silicate Board is a building material used in various applications due to its strength, fire resistance, and sound insulation. However, like all materials, it has some disadvantages:


1. Weight: Calcium Silicate Boards are heavier than other types of boards, such as gypsum boards. This can make handling and installing challenging, increasing labor costs.


2. Cost: Calcium Silicate Boards are generally more expensive than other boards, such as gypsum or plywood. This can be a significant factor in large projects where cost is a concern.


3. Limited Flexibility: These boards are rigid and have limited flexibility compared to other materials. This can limit their use in specific applications.


4. Moisture Sensitivity: While calcium silicate boards are somewhat resistant to moisture, they can still absorb water and dampness if not correctly sealed, leading to damage over time.


5. Cutting and Installation: Cutting and installing calcium silicate boards can be more challenging than other materials. The board's hardness can wear down tools faster, and it can produce a significant amount of dust when cut.


6. Aesthetics: While this is subjective, some people find the appearance of calcium silicate board less appealing than other materials, such as natural wood.


7. Thermal Conductivity: Although calcium silicate has low thermal conductivity, it's not as good an insulator as some other materials, like polystyrene or polyurethane foam.


As with any material, it's essential to weigh these disadvantages against the advantages and the specific requirements of your project when choosing a building material.
