Magnesium Oxide Board
What is a magnesium oxide board?
The creation of a magnesium oxide board takes many steps. First and foremost, the raw materials must be prepared. These materials are then mixed thoroughly and a board is created. In order for the board to be created, non-woven fabric, fiberglass mesh, and slurry must be added in and mixed together. Magnesium oxide is often referred to as “magnesia”, and it is used in countless residential and commercial projects all over the world.
The boards must then be cured, demolded, and soaked. The “soaking” of MgO boards helps to prevent MgO boards from “sweating.” MgO boards are water-resistant, but this sweating can eventually cause discoloration, warping, and other kinds of damage.

There’s a range of advantages when it comes to using magnesium oxide boards as building materials. First, it is fire-resistant, which is particularly relevant for projects that are building in an area known for fires, or simply concerned about a potential fire at some point.
The material is also water-resistant, which is vital for those concerned about flooding or any other potential water disasters. It’s also incredibly energy efficient. It’s easy to see why more projects are using magnesium oxide boards than ever before, and that trend isn’t likely to change anytime soon. The material is also impact-resistant and silica/asbestos free. It can be used for other applications, such as cement-based siding.
Magnesium oxide is also mold-proof and great for sound insulation. Other building materials might also be prone to asbestos or formaldehyde. This isn’t the case with the magnesium oxide boards supplied by EverythingMgO, and its service life of 25 years is a huge plus for builders who are thinking about longevity.
