Component of a Magnesium Oxide Board

The first MgO boards were utilized in Asia and Europe. In 2003, this relatively new building material was introduced to the American market. Despite this, until recently, many builders have not employed it. It was first utilized in coastal structures because it could resist hurricane-like weather and would not rust from the sea breeze.


More variations of this product were then developed to meet the needs of builders. So, how is the unique product made, and what exactly does it contain? Let's take a look at it in this blog.

What are the main components of a MgO Board?

Magnesium Oxide

Goes without saying, magnesium oxide is a vital component of a MgO board. Magnesium is a solid at ambient temperature and, like aluminum, is lightweight in its purest form. Because of its strength and lightweight, magnesium is employed in sports cars and airplanes. This chemical stabilizes and becomes non-flammable when coupled with oxygen, making it perfect for home construction and furnace lining.

These boards may be made sustainably because magnesium deposits can be found all over the world. In comparison to other building materials, they have a longer life cycle, which means less waste.




Additives (Magnesium Cement/Wood Flour)

Wood flour, magnesium cement, and other additives, in addition to the base materials used in the making of MgO boards, are added to the mixture, depending on the grade of MgO boards being produced. Because MgO boards come in a variety of textures, thicknesses, and quality, the additions in each type vary slightly.

Fibers (Fine Screed, Glass Mesh)

For further strength, durability, and flexibility, MgO boards are reinforced with some form of fiber. To reinforce the boards, fine screed, glass mesh, or other fibers are frequently employed, either within the board or on its surface.

MgO boards are handcrafted one at a time. When they're poured into a casting tray, they're trimmed to length. After allowing the trays to set horizontally, they are cured vertically. The temperature at which the MgO boards are cured varies depending on the type of MgO board being made.

Multi-Support Sulfate Magnesium Oxide Boards, for instance, is a low-density board with two layers of high-tensile glass fiber mesh inserted in it. This enhances the mechanical qualities as well as the fire resistance. These boards are eco-friendly and available in a variety of finishes and colors.
