Sulfate MgO Fire Board --Green Alternative to Traditional Drywalls
MagMatrix Sulfate MgO FireProof Board is made out of Sulfate MgO Formula that is chloride free and moisture-resistant and is suitable to be applied at the wet area for modern construction as the green alternative to fire-rated drywall.
Magnesium oxide (MgO) mixed into cement to create thin panels, known as MgO boards, have emerged as the greener alternative to traditional drywalls in recent years. While they are not organic, tests show that MgO boards are not damaged by water; they are resistant to mold, non-combustible and quite resilient to impact. MgO boards hold up well when frozen and thawed while being solid enough to fix nails and screws. They are also used as wind barrier boards to insulate against the cold, wind, noise, in addition to stiffening exterior walls and ceilings, render carrier board, SIP panels, etc. MgO board is available for building construction and comes in various thicknesses and sheet sizes. It also comes in various grades, such as smooth finishes, rough textures, and utility grades. It is white, beige or light gray in color, and has a «hard» sound when rapped with your knuckles-somewhat like cement fiberboard.
Like any sheathing board, the MgO board can absorb water but its performance is unaffected. Thus it can be used indoors and outdoors, and in damp locations, such as showers. Like Portland cement-based sidings, if MgO is used outdoors in an exposed location, it needs sealing in much the same way as cement. MgO is used structurally-as in bracing for walls-and also semi-structurally, such as an underlayment for flooring. Magnesium oxide board was developed many years ago as a cheap alternative to cement fiberboard. It turned out as a coincidence to be a product with many superior characteristics. MgO Board was extensively used in construction during the 2008 World Olympics buildings in Beijing…and was used in the world-famous Taipei 101 building which up until recently was the world's tallest building.
