Magnesium Oxide Wallboard Application: Interior Uses

Walls and Partition Systems

Magnesium oxide wallboard application works for many inside walls. Builders pick it for office, school, and hospital partitions. It keeps people safe because it does not burn. It also stops fire better than other boards. This board does not soak up water like gypsum board. Your walls will not get bigger or moldy in wet places. The table below shows how magnesium oxide wallboard and gypsum board are different for inside walls:

You need special screws and tools to put up magnesium oxide boards. Use screws that do not rust and a saw with a carbide blade. This helps you cut the board clean and finish strong. Keep the boards dry and use glue for corners. These steps help your walls last longer and stay tough.

Ceilings and Subflooring

Magnesium oxide board is good for ceilings and subfloors inside. Its dense structure keeps out water. You do not have to worry about mold or water damage. Gypsum boards can get wet and moldy, but magnesium oxide boards stay strong. This gives you a safer and cleaner room.

Magnesium oxide wallboard application is great for subfloors because it holds heavy weight. It does not crack or bend like plywood. Cement boards are strong but heavy and hard to use. Magnesium oxide board has high compressive strength, up to 25 MPa. This helps floors stay steady. This is important for tall buildings that need strong floors.

Wet Areas and Bathtub Enclosures

Magnesium oxide wallboard application is good for wet rooms like bathrooms and kitchens. It does not take in much water, so it stays strong. The table below shows why it works well in wet places:

In bathtub spaces, magnesium oxide board only takes in 0.34% water. This stops swelling and damage. Cement board can take in more water, up to 1.58% after soaking. Magnesium oxide boards protect your wet rooms better.

• Magnesium oxide wallboard takes in only 0.34% water, so it does not swell or break.

• Cement board can swell up to 1.58% after soaking for 504 hours.

Soundproofing with Magnesium Oxide Boards

Magnesium oxide wallboard application helps block noise in rooms. It stops sound better than regular gypsum board. Its dense structure gives higher sound ratings. You can see the difference in the table below:

Regular gypsum board has a sound rating near 30. Special soundproof gypsum boards reach 40 to 42. Magnesium oxide board can go even higher, so it blocks more noise. It also resists hits and fire very well. Magnesium oxide boards keep their shape in wet rooms, so your quiet walls last longer.

Tip: Use magnesium oxide wallboard application in bedrooms, offices, and classrooms to make rooms quieter and more peaceful.

Magnesium Oxide Board Application: Exterior Uses

Facades and Exterior Siding

Magnesium oxide boards are good for outside walls and siding. People use them on homes, stores, and public buildings. These boards protect against rain, wind, and sun. They do not rust or break in bad weather. They stay strong and keep their shape, even near the ocean or in wet places.

If you pick magnesium oxide boards for siding, you get many good things:

• Energy efficiency: These boards help keep heat in or out. This can make your heating and cooling bills lower.

• Cost-effectiveness: You save money because you fix less and pay less for energy.

• Moisture resistance: The boards stop water from getting inside. This keeps your walls dry and safe.

• Mold prevention: You do not have to worry about mold growing behind the siding.

• Durability in harsh conditions: These boards last a long time, even in storms or very hot or cold weather.

• Exceptional fire resistance: The boards can stop fire for up to four hours. This helps keep your building safe.

• Stability in wet conditions: The boards do not bend or swell. Your siding stays flat and strong.

You can use these boards for new buildings or when fixing old ones. Many big projects and public places use magnesium oxide boards. They are waterproof and last longer than fiber cement siding. Fiber cement can soak up water if you do not seal it well. Magnesium oxide boards stay strong in heat and wet air.

Note: Always put a special coating or paint on magnesium oxide boards outside. This makes them last longer and look nice.

Sheathing and Soffits

Magnesium oxide boards are great for sheathing and soffits under roofs. You can use them in schools, stores, and other big buildings. These boards give you a strong, waterproof layer for your walls.

“MgO sheathing is classified as an A1 fire-rated material, which means it can withstand direct exposure to flames and extremely high temperatures without igniting, emitting toxic smoke, or compromising its structure.”

You can feel safe because your building has extra fire protection. These boards also stop bugs and do not rot. This makes them smart for soffits and roof edges. You can put them up with normal tools. They do not crack or split like wood.

If you want walls that are waterproof and safe from fire, magnesium oxide boards are a top pick for sheathing and soffits. You can trust them to protect your building for many years.

Protected Outdoor Applications

You can use magnesium oxide boards in covered outdoor places. These include walkways, balconies, and outdoor ceilings. The boards do not break or get weak when the weather changes from hot to cold.

Here is how magnesium oxide boards compare to other boards in freeze-thaw tests:

You can see magnesium oxide boards work as well as fiber cement in tough weather. They do much better than gypsum plasterboard, which can crack or get weak in cold, wet weather.

If you want outdoor spaces to stay dry and strong, magnesium oxide boards are a good choice. Always use a protective finish to help the boards last longer and look good.

Performance Comparison: Magnesium Oxide Boards vs Traditional Materials

Fire and Moisture Resistance

Are magnesium oxide boards fire resistant? Yes, they are. These boards give the best fire safety in buildings. They have an A1 non-combustible fire rating. This is the highest fire safety level. You can use them for fire-rated walls in schools, hospitals, and homes. The table below shows how magnesium oxide boards, gypsum board, and cement board compare for fire safety:

Magnesium oxide boards protect from fire for up to four hours. Gypsum board lasts only one hour. Cement board lasts two hours. If you want fire resistance for a long time, magnesium oxide boards are the best.

Moisture resistance is important in buildings. Magnesium oxide boards do not swell or break in wet air. They keep their shape in bathrooms, kitchens, and outside walls. Some boards use other minerals, so they take in more water. Still, magnesium oxide boards resist water better than gypsum board.
