MGO board, also known as magnesium oxide board, is gaining in popularity as an interior wall material due to its fire-resistance, moisture-resistance, and sound-proofing properties. But is there any exterior mgo board?

MGO board is an ideal material for interior walls because it is impact-resistant and lightweight, making it easier to install. However, it is not recommended to use MGO board for external walls due to its lack of durability. While it is more fire-resistant than drywall, it is not as strong as other materials such as cement board and is not suitable for use in high-traffic areas.

MGO board is also not recommended for external walls because of its limited weather-resistance. It is not waterproof, so it is not suitable for areas that are exposed to the elements. Additionally, MGO board is not UV-resistant, so it may fade or discolor over time if exposed to direct sunlight.

Despite its limitations, exterior mgo board can be used in certain external applications, such as a non-load-bearing siding or a decorative facade. It can also be used in combination with other materials, such as brick or stone, to create a more weather-resistant external wall.

In conclusion, while MGO board has some advantages, such as being fire-resistant and lightweight, it is not recommended for external walls due to its lack of durability and weather-resistance. However, it can be used in certain applications if combined with other materials.
