Drywall has been the go-to construction material for decades– it can be used to construct ceilings and walls, and even several designs feature like arches and eaves. This material has been a staple in the industry because it is relatively durable and relatively easy to install and repair. Run by effective project management tools, many building projects that use drywall have succeeded. However, several disadvantages come with it, such as its susceptibility to water damage and recycling difficulty.

Modern innovations have once again solved a few of construction’s problems. Around the early 2000s, MgO boards, or Magnesium Oxide boards, have been getting attention in the industry. Many take advantage of its potential and have dubbed it “a greener alternative to drywall.”

What are MgO Boards?

MgO boards are construction panels that are made by combining magnesium and oxygen through heat and pressure to create MgO, or magnesium oxide. Once the heating process is done, the product shares the same characteristics as stone.

To turn them into panels, the stone-like material is crushed and ground into a fine powder. It is then mixed with water, perlite, chloride, sulfate or Epsom salts, and wood dust (cellulose), among other materials.

Uses of MgO Boards

MgO boards are similar to drywall in the sense that they can be used almost everywhere in constructing buildings. Specifically, they can be applied for houses as firewalls, wall panels, tile backers, ceiling boards in the interior, and sheathing, trim, siding, and fascia on the exterior. 

Friendly to the environment

One of the most significant benefits of magnesium oxide boards is its positive impact on the environment. As previously mentioned, MgO boards do not contain chemicals like benzene, ammonia, and asbestos, which also have negative environmental effects. 

Aside from the direct effects, MgO board production has additional long-term environmental benefits. First is its extended lifespan. Because of MgO boards’ incredible strength and resistance to several factors, buildings will tend to stand longer and thus won’t need significant repairs or renovations.

One other long-term effect MgO board manufacturing has is a reduced carbon footprint. It consumes only about 25% to 50% of the energy needed to produce calcium hydroxide or Portland cement. Additionally, the extreme green curing phase allows the material to capture CO2 carbon dioxide.

Magnesium oxide boards are recyclable and are also considered “nutritional waste.” This means that their lack of toxic substances does not compromise landfills or water sources. They can even be ground up and sprinkled into the soil as a nutrient.
