Magnesium Oxide (MgO) is an inorganic mineral compound made from calcined magnesium. When combined with magnesium sulphate and reinforced with fiberglass mesh and natural fibres, it forms a strong, stable, non-combustible cement board.

Unlike gypsum, drywall or cement products, MgO panels are:
  • Non-combustible, They won't burn, drip, or release toxic gasses or fumes.
  • Water-resistant, no warping, swelling, or degrading when exposed to moisture.
  • Mold-resistant, They don’t support fungal or microbial growth.
  • High-strength, offering excellent impact resistance and structural stability.
​MgO boards are used as an alternative to traditional gypsum, plywood, OSB, or cement board in both interior and exterior wall assemblies.

They’re ideal for projects that need code-compliant fire protection, durability, and speed of installation—without sacrificing environmental performance or long-term reliability!
