Description

MgO subfloor board is a modern construction material made from magnesium oxide cement, a naturally occurring mineral. It is a durable, fire-resistantand water-resistant alternative to traditional subflooring materials like: plywood, OSB, glass mesh cement board, gypsum board designed to provide a stable and strong base for various finished flooring types.

Key features and benefits

  • Durability and strength: MgO board is structurally strong, often exceeding traditional materials like OSB, Plywood and can handle heavy foot traffic without cracking.
  • Fire resistance: It is non-combustible and will char rather than burn, maintaining its structural integrity during a fire.
  • Water and moisture resistance: MgO subfloor board is highly water-resistant and will not warp, swell, or delaminate when wet like wood products might, which simplifies installation in damp areas.
  • Mold and pest resistance: Its antimicrobial properties make it naturally resistant to mold, mildew, and termites, improving indoor air quality and longevity.
  • Eco-friendliness: It is made from a naturally occurring and abundant mineral and is often recyclable, making it a more sustainable choice with a lower carbon footprint than some traditional materials.
  • Easy installation: The installation process is similar to that of traditional wood subflooring, and it can be cut with standard tools
