MgO Board

Magnesium oxide , more commonly called magnesia, is a versatile mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial  building construction . Some versions are suitable for a wide range of general building uses and for applications that require fire resistance, mold and mildew control, as well as sound control applications and many other benefits. As an environmentally friendly building material, magnesia board has strength and resistance due to very strong bonds between magnesium and oxygen atoms that form the magnesium oxide molecules (chemical symbol MgO).

Magnesia boards are used in place of traditional  gypsum drywall  as wall and  ceiling  covering material and sheathing. It is also used in a number of other construction applications such as fascias,  soffit , shaft-liner and area separation, wall sheathing, and as tile backing (backer board) or as substrates for coatings and insulated systems such as finish systems, EIFS, and some types of  stucco .

Magnesia cement board for building construction is available is various sizes and thickness. It is not a paperfaced material. It generally comes in a light gray, white or beige color. Numerous versions and value of grades exist including smooth face, rough texture, utility, versatile grades as well as different densities and strengths for different applications and uses.
