Magnesium Oxide Board

Suparna has been producing quality MgO board for over 16 years. MgO board is an upgraded product that replaces wood board and gypsum board. The service life of Suparna MgO board can reach at least 25 years for indoor application.

Highlight: Not Sweating

Since 2010 Denmark has witnessed a great loss of over EUR100 million caused by unqualified MgO “sweating board”. Different from those, Suparna MgO boards are halogenide resistant and will not sweat because of the soaking process, as shown in the video.
