In this article, I will guide you through the most important points about applying MgO boards.
Application of MgO Boards
MgO boards are used for interior and exterior walls, ceilings, flooring substrates, trim, fascia, and structural panels. They provide fire resistance, moisture resistance, sound insulation, and durability. This makes them ideal for kitchens, bathrooms, bedrooms, and areas with high traffic or extreme weather conditions.
Interior Applications
Like plywood or drywall, MgO boards can be used for interior and exterior applications. In the interior, construction professionals use them for walls and ceilings. They are also excellent as flooring substrates in kitchens, bathrooms, bedrooms, and living rooms.
MgO boards are durable and provide sound insulation. That is one of many reasons people use them for regular interior walls.
You can use them in bedrooms for a quieter and more fire-resistant environment. They also have many advantages, one of which is moisture resistance. That is why you may find them in bathrooms and kitchens.
MgO boards can also improve sound insulation within a building. They reduce noise transmission between rooms and floors. That is why they are suitable for use in residential and commercial buildings’ walls, floors, and ceilings.
Exterior Applications
Because of their versatile nature and numerous benefits, MgO boards are often used for exterior wall sheathing. Construction professionals also use MgO boards as an underlayment for exterior siding materials. The reasons are many!
MgO boards add structural strength and impact resistance to exterior walls. They can also be applied as an underlayment for roofing materials. The reason- they provide fire resistance and extra structural support.
MgO boards are very strong, making them great for use as structural panels in walls, floors, and roofs. In load-bearing walls, MgO boards can replace traditional materials, such as plywood or OSB. In such locations, MgO boards provide superior fire resistance and durability. That is why they are great for constructing exterior walls in residential and commercial buildings.
They are especially great in areas prone to extreme weather conditions or requiring high fire safety standards.
Versatile MgO Boards

MgO Boards for Trim
That’s not all! You can use MgO boards for trim and fascia. They are also used to finish edges and create decorative elements around the building’s windows, doors, and corners. This use takes advantage of MgO boards’ weather-resistant qualities. They don’t rot, warp, or get damaged by insects, ensuring they last a long time.Furthermore, MgO boards used as trim need less maintenance than traditional wood trim. This makes them an attractive and practical choice for exterior detailing.
MgO Boards as Fascia
When installed along the roof’s edges, MgO boards serve as fascia boards covering the rafters’ ends. In this role, MgO boards withstand exposure to the elements. And all that without deteriorating, ensuring durability and longevity, Additionally, they give the roof a neat, polished look, improving the building’s appearance. Using MgO boards for fascia, homeowners can achieve a durable and appealing exterior finish. Plus, it requires minimal maintenance.
MgO Boards as Flooring Substrate
Are you tired of worrying about water damage in your bathroom or kitchen? I have some good news. MgO boards are your moisture-fighting champions! Highly effective in wet areas, they can be used as a substrate for tiles in bathrooms, showers, and kitchens.
They are excellent flooring substrates, either under tiles or hardwood floors. They can be used instead of ceramic tiles in bathrooms or to provide a stable base for hardwood or laminate flooring.
MgO Boards for Ceilings
MgO boards offer several advantages that make them a suitable choice for ceilings. Bathrooms and kitchens are common sources of moisture that can rise and affect ceilings. As they are moisture-proof, this feature prevents them from warping and sagging. It is harder for mold to grow and develop on materials such as magnesium oxide. This is especially beneficial in areas with high humidity or potential leaks.
MgO Boards as Exterior Cladding
Beyond their sheathing, MgO boards can also serve as exterior cladding material. They provide a durable and fire-resistant exterior finish. On top of all that, MgO boards enhance a building’s aesthetic appeal. Also, it provides robust protection against the elements.
MgO Boards in Fire-Rated Walls
MgO boards are often used in fire-rated wall assemblies to enhance fire resistance. Their fireproof nature makes them perfect for creating fire-resistant walls. That is particularly helpful between different parts of a building.
This application is crucial for meeting building codes and safety regulations. This is especially important in multi-family and commercial buildings.
