Magnesium Oxide Board / SUPERTEC Magboard
What is Magnesium Oxide Board?Magnesium oxide (MgO) has been used dating back thousands of years. It has been found that magnesium oxide was used in the Great Wall of China as a cement form. China has the world’s largest deposits of magnesium oxide, which is sufficient to resupply the world with cement fibre, gypsum and wood partitioning and ceilings every year for the next 800 years. Magnesium oxide board (MgO board) is a factory-made, non-insulating sheathing board product. It is made primarily of magnesium oxide, and is commonly called simply (MgO) (pronounced emm-gee-oh) due to its chemical composition of magnesium and oxygen. MgO board is similar to gypsum board or cement fibre board – however with several improved characteristics such as fire resistance, weather ability, strength, resistance to mould and mildew, flexibility, adherence advantages and so on.
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 fibre board. 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.
