Magnesium Oxide Board


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), among other materials.
  • Magnesium Oxide Board is a environmentally- friendly building material.
  • The production of MgO is energy efficient and produces few greenhouse gases.
