Composition of Magnesia board

Chloride and Magnesium Oxide
Main components that determine the characteristics of the "Ukrmagnesit" MgO board. Their mutual reaction creates a very strong crystal lattice that serves as a container for fillers.
Mineral additives
The addition of mineral components in the form of various kinds of clay, pearlite, etc., reduces thermal conductivity coefficient of magnesia board, as well as its weight, while contributing to an increase in sound insulation.
Fine wood sawdust
Give the material volume and lightness.
Fibreglass mesh
Serves for double-sided reinforcement of magnesia boards. This component gives the board strength and elasticity.
Thanks to this composition of components and unique production technology, the "Ukrmagnesit" MgO board receives high performance characteristics directly on the production line, without the use of third-party modifying substances, impregnation, etc.

Due to 100% environmental friendliness, MgO board is widely used for finishing works in children 's rooms.

Priority directions of usingf MgO board "Standard":

  • Magnesite board of this kind is recommendded for finishing works in places with increased requirements for strength and wear resistance of structures (sports centers, shopping and entertainment centers, cinema, heated warehouses, etc.);
  • It is recommended to use MgO board “Standard” in finishing works in buildings and structures with increased requirements of sanitary and epidemiological nature, namely: - medical institutions, laboratories, sanatoriums, hotels, restaurants, cafes, educational institutions, production workshops of food industry, etc.).
The MgO board “Premium” is widely used in interior finishing works with high- humidity or wet conditions. It is used in residential, administrative, public and industrial buildings for finishing walls, interior partitions, floors, suspended ceilings, etc. It can also be used for finishing works in areas without heating: basements, parking lots, warehouses, garages, balconies, etc.

Taking into account the large demand for specific construction and finishing materials, our company has tested and launched production of MgO board with fire protection function called «FireStop», and is distinguished by a high content of magnesium. Also we have the MgO board "WaterStop", a water-resistant material with addition of magnesium sulfate for premises with increased humidity. These magnesia boards are the subtypes of the «Premium» board.

Main application areas of MgO board «Premium»:

  • it is used for finishing works in industrial and manufacturing facilities with increased requirements for resistance to aggressive media: acids, alkali, oil products;
