Magnesium oxide boards are available in many surface finishes depending on the intended application. One of the most popular options is the non-recessed MGO boards.
In this article, we shall explore fundamental aspects about non-recessed MGO boards.
What is Non-recessed Magnesium Oxide Board?

Non-recessed magnesium oxide board is a building material type made mainly from magnesium oxide but strengthened with other materials like cellulose or fiberglass fibers. Usually, non-recessed MGO boards are known for their square-cut edge.
That is, they don’t have any form of indentationor grooved on their edges like for the case of recessed MGO boards.
Advantages of Non-recessed MGO Board
Non-recessed MGO boards will offer you countless benefits. These include:
· Highly Resistant to Fire
MGO boards mostly emit 30 lbs. maximum water as vapor when there is a fire outbreak. This helps to cool off as well as contain fire. Also, these boards come with up to 2 hours of protection against fire.
· Resist Water and Moisture
MGO boards will never disintegrate when you have them immersed in water for shorter time periods. Since they do not absorb water or moisture, these boards do not swell, warp, delaminate, etc.
· Versatile
You can use these boards perfectly both for exterior and interior uses. This makes it versatile for different types of applications.
· Come with High Level of Strength
Since MGO boards have fewer grooves, their structural integrity is always in place, and they are always strong.
· Durable
MGO boards are resistant to wear, besides, this board is also very tough as well. This makes them perfect for areas with high traffic.

· Smooth Surface
Due to their smooth surface, they are easy to install and handle as well. So, you do not waste too much time when using them.
· Eco-friendly
Magnesium oxide naturally doesn’t release any dangerous or harmful chemicals into the environment. This makes its contribution to the environment the best. Generally, it is non-toxic which means it doesn’t contain ammonia, benzene, and asbestos and is safe.
· Soundproof
MGO boards have the very best sound absorbing features. This makes them perfect when you want to create noise-dampening partitions.
· Termite Proof
Magnesium oxide in MGO boards acts as deterrent to termites. Due to this chemical compound in the boards, they are inorganic, don’t attract termites, carpenter ants, etc.
Applications of Non-recessed MGO Board
When it comes to applications, you can use non-recessed MGO boards in many areas. In fact, non-recessed MGO boards are versatile construction materials that fit many applications:
- Used for interior walls
- Perfect for flooring
- Ceiling works
- Exterior cladding
- For insulation and fireproofing
FAQs
1. What is MGO Board?
Non-recessed magnesium oxide board is a building material type made mainly from magnesium oxide but strengthened with other materials like cellulose or fiberglass fibers.
2. What is the difference between Fiber Cement Board and MGO Board?
Although both are resistant to fire and durable, MGO boards have a higher level of moisture resistance compared to fiber cement board.
3. How does Non-recessed and Recessed MGO Boards Compare?
| Features | Non-recessed | Recessed |
| Surface Texture | Smooth surface | Indentations or grooves |
