The sheathing board material used in residential construction has significant impact on the project’s lifespan and durability. Ideally, you want to choose a material that not only provides appropriate tensile strength to hold up against adverse weather conditions, but also offers good mold, fire and mildew resistance.

Pure magnesium is flammable; however, when combined with oxygen under extreme heat and pressure produces a stone-like material called MgO. Magnesium oxide provides high-impact resistance, flexibility and durability due to the powerful bonds between the oxygen and magnesium oxide molecules, in addition to outstanding fire resistance.

Due to these reasons, most contractors, engineers and builders today recommend MgO as an ideal sheathing board material for construction; it offers superior performance in every category when compared to cement, wood-based products and conventional gypsum.

Let’s look at some reasons why you need to opt for MgO boards when building a new home:

MgO is water-resistant

Unlike gypsum and cement boards that require replacement after an HVAC system leak or a flood, MgO’s structural integrity isn’t affected by exposure to water. Not only can it withstand standing flood water indefinitely, but it also resists mold and mildew growth once the flood has subsided. This is exactly why MgO boards are highly used in areas susceptible to floods.

Environmental friendly characteristics

MgO SIPs are 100% safe to use; they don’t contain any toxic materials like asbestos or organic solvents in their construction. The best part? They don’t release harmful gases in the environment, which makes them perfect for long-term use compared to particle boards or plywood.


What’s more is that the construction process of MgO SIPs doesn’t produce a lot of waste at job sites—eventually reducing the amount of materials that end up in a landfill.

It comes as no surprise that MgO panels are revolutionizing the residential construction arena in an ecological and green way!

MagMatrix Non-Combustible Sheathing Board

Avoid pest infestations with MgO boards

MgO sheathing boards are some of the very few building materials in the market that are 100% termite proof! This can save you hundreds of dollars that will otherwise be spent on fumigation services. With Magnesium Oxide boards, you wouldn’t have to worry about sudden structural failure!

MagMatrix is a renowned supplier of asbestos-free, non-combustible, fire and moisture-resistant Magnesium Oxide panels and boards, which can be used as sheathing boards, partitions and drywalls.
