MGO board can handle much higher temperatures than OSB or plywood. It does not catch fire or give off toxic smoke. You get a safer building when you use it. Gypsum and cement board also resist fire, but MGO board often lasts longer in extreme heat. This makes it a smart choice for anyone who wants extra protection.

Tip: If you want to meet strict fire codes, MGO board helps you do that with less worry.

Fire Applications

You need strong fire resistance in many places. MGO board works well for:

  • Firewalls between rooms or units

  • Exterior sheathing on homes and offices

  • Ceilings in garages or basements

  • Stairwells and corridors in apartment buildings

You can use MGO board in places where fire safety is the top concern. Builders often pick it for schools, hospitals, and high-rise buildings. You can also use it in homes, especially near kitchens or garages. When you want to protect people and property, MGO board gives you peace of mind.

2. Moisture & Mold Defense

Moisture Resistance

You want your building to stay strong, even when it gets wet. Many sheathing boards soak up water and lose their strength. Gypsum and OSB can absorb moisture quickly. When this happens, they swell, warp, or break down. You do not want that in your walls.

MGO board stands out because it resists water. It does not soak up moisture like gypsum or OSB. You can use it in places where water is a problem. For example, bathrooms, kitchens, and basements often have high humidity. MGO board keeps its shape and strength, even in these damp spaces.

Here is a quick comparison:

Tip: You can use MGO board for exterior walls or as a tile backer in showers. It will not break down when exposed to water.

Mold & Insect Protection

Mold and insects can damage your building and harm your health. Some boards, like OSB and gypsum, give mold a place to grow. Insects, such as termites, can eat wood-based boards. You want to avoid these problems.

MGO board helps you do that. It does not support mold growth. Its mineral makeup keeps insects away. You can use it in basements, crawl spaces, or anywhere you worry about mold or bugs.

  • You get better air quality.

  • You protect your building from hidden damage.

  • You make your space safer for everyone.

MGO board also supports a healthier environment. It does not release harmful chemicals. You can feel good about using it in homes, schools, and hospitals.

3. Strength & Versatility

Plywood and OSB can bend or break if they get wet or face heavy loads. Cement board is strong, but it can be heavy and hard to handle.
