30 Aug How Thick is a Magnesium Oxide Board?
Table of Contents
Looking for a building material that is strong, durable, and elegant? Who wants to compromise on aesthetics, especially when building a home? It’s non-negotiable, and we agree with you.
MgO boards are a simple option as they come in multiple thicknesses. You can pick the thickness that best suits your requirements. Different MgO boards are used for ceilings, wall sheaths, and separators.
We will explore the thickness options for MgO boards and how different options assist in building a home. So, pick your notebook to note all the necessary details and get into the topic!
What are MgO Boards?
MgO is a popular and eco-friendly substitute for traditional building materials. It’s an inorganic product known for its extraordinary abilities. Here are a few of them;
- Heat resistance
- Fire resistance
- Moisture resistance
- Mold resistance
- High strength and weight-bearing capacity
- Noise resistance
- Eco-friendly material
Based on their characteristics, MgO boards are widely used in construction and finishing.
But what makes them a rival of cement and other construction materials? Let’s find the magical substituents that hold them back.
What are MgO Boards Made Of?
As the name indicates, MgO boards are made of magnesium and oxygen. The material is 100% natural and abundant in oceans and seas. In addition to magnesium and oxygen, certain additives are added to give the material strength and durability.
However, the production process is cleaner and doesn’t harm the environment. That’s why it’s our favorite, too!
Now that you know what makes MgO boards a versatile material, it’s time to talk about its thickness.
Thickness Options for MgO Boards
You can get MgO boards of different thickness options, from ¼ to 1 inch. But it’s more than just the thickness. It’s about durability, strength, and usage. The common thickness options available for MgO boards are:
- 1/4 inch (6 mm)
- 1/2 inch (12 mm)
- 5/8 inch (15 mm)
- 3/4 inch (18 mm)
- 1 inch (25 mm)
Based on their applications, you can pick the boards that best suit your requirements.
Factors Affecting the Choice of Thickness
Before choosing the MgO board thickness, consider where you’re using it. MgO boards have multiple applications in the construction industry, including:
- Walls sheathing
- Ceiling lining
- Subflooring
- Tile backer boards
- Firewalls and partitions
- Fascias and soffits
- Shaft liners
- Structural panels
Choose the MgO boards depending on where you’re using them.
Different factors influence the choice of thickness, such as:
- Geographical area
- The purpose of use
- Durability and strength
- Weight
- Fire resistance
- Water resistance
- Thermal resistance
- Sound insulation
- Budget
For example, a thin MgO board suits partitions and ceilings. A thick one would be preferable for subflooring.
Thickness Variation of MgO Boards
Now that we know all MgO boards are ready, we have chosen the one that matches our needs. Let’s jump into the thickness variation and their applications;
But first, repeat the general rule of thumb:
Thick boards are used for structural applications, and thin boards are more suitable for ceilings and wall sheathing.
Since MgO boards have way more applications than we can imagine, they’re used in different construction projects.
Thin MgO Boards
The thin MgO boards (¼ inch or 6mm) have usual applications in ceilings and wall linings. They are;
- Lightweight
- Easy to install
- Provides good fire resistance
- Good moisture resistance
However, thin boards have low structural strength.
Thick MgO Boards
On the contrary, thick MgO boards (¾ inch or 18 mm and 1 inch or 25 mm) have structural application. Thick MgO boards have;
- High impact resistance
- High bending strength
- Exceptional weight-bearing capacity
Medium Thickness
There’s also a category of MgO boards with medium thickness (½ inch or 12 mm and ⅝ inch or 15 mm). These boards have versatile structural and finishing applications. These boards offer;
- Dimensional stability
- Moisture resistance
All clear for now? Let’s head toward some technicalities that come with thickness variation.

Advantages of Varying Thickness
Thick MgO boards directly impact the durability and structural performance. Here are the benefits of using thick MgO boards;
1. Durability and Performance
Thickness directly influences the durability of MgO boards. Thick MgO boards have high structural strength and can bear the weight. The increased thickness provides;
- High bending strength
- Better weight-bearing capacity
- Great moisture resistance
Research showed that MgO boards with around 20 mm thick fiber-reinforced polymer (FRP) strips have extraordinary bending strength and overall structural performance.
2. Fire Resistance
MgO boards got a lot of praise for their excellent fire-resistance properties. The thickness of MgO boards results in high structural integrity and thermal insulation that allows them to withstand high temperatures.
3. Thermal Insulation
The more thick material you use, the better results you’ll get. Thick MgO boards are a visual example of this. A high thickness results in high thermal resistance and lower thermal conductivity.
At room temperature, the thermal conductivity of MgO boards is 0.45 W/m/°C. This reduces to 0.12 W/m/°C when temperature rises. The low thermal conductivity makes thick MgO boards a good thermal insulator.
4. Sound Insulation
Thick MgO boards are excellent sound absorbers and effectively reduce sound transmission. The substituents like chloride, oxides, and wood chips make it an insulating building material. Moreover, density and structural integrity are also added.
5. Moisture Resistance
The thick magnesium oxide boards have high hygroscopic thresholds. This means that the material can absorb water without swelling.
The high moisture resistance of thick MgO boards makes them reliable for structural construction.
Cost Implications
Your cost can also increase depending on the thickness of the MgO boards. The thicker the board, the more material is required; eventually, the cost increases. The estimated prices are as follows:
| Thickness of MgO boards | Dimension | Price |
| 1/4 inch (6 mm) MgO boards | 4 ft x 8 ft sheet | $30-40 |
| 1/2 inch (12 mm) MgO boards | 4 ft x 8 ft sheet | $45-55 |
| 3/4 inch (18 mm) MgO boards | 4 ft x 8 ft sheet | $50-60 |
| 1 inch (25 mm) MgO boards | 4 ft x 8 ft sheet | $60-70 |
