Purpose and use
Magnesia is widely used primarily as wallboard alternative to conventional gypsum-based drywall. The magnesia boards can be scored and snapped, sawed, drilled, and fastened to wood or steel framing.
It can be used for interior or exterior applications.
Magnesia boards are a good example of the advances made in construction materials to meet changes in building codes for safety, durability, mold and bacterial resistance, and humidity control.
