Magnesium Oxide Board (MGO)




The technology behind Penda Magnesium Oxide Board offers superior performance versus traditional products. While Penda mgo boards were initially designed to replace asbestos panels, our research lead us to discover that this product could replace traditional components, such as gypsum, cement board and even plywood.  Penda MGO board are non -flammable, water-resistant, insect-resistant and provide superior impact protection than traditional materials. They are eco-friendly and will have a positive impact on your health given their resistance to mould.

The Penda mgo board comes in an eggshell colour with a finish that is smooth on one side, ideal for paint applications, and slightly rough on the other, suitable for ceramics. They are used worldwide as a fireproofing, non-flammable product. They are free of any trace of asbestos, formaldehyde, benzene or radioactive elements emitting toxic fumes.


Penda MGO board features the following non-toxic components: magnesium oxide, magnesium chloride, perlite, sawdust and fiberglass mesh. This makes them ideal for residential, commercial and industrial constructions, such as:

  • Single-family homes
  • Garages Schools
  • Indoor and outdoor partitions
  • Hospitals
  • Bathrooms
  • Restaurants
  • Fireproof walls
  • Office buildings
  • Basements
  • Hotels
  • Ceilings
  • Building envelope
  • Any major project

Outdoor Applications

Penda MGO board features a completely homogenous composition, thereby preventing delamination issues. They are made of inedible, tasteless materials that do not attract insects. Here are a few relevant details regarding the mgo board.

  • Density: 0.85-1.3T-M3
  • Flame resistant +2 hours (l2mm)
  • Non-flammable
  • Shrinkage: 0.3%
  • Compression: 1.52Mpa
  • Frost resistance: -40 degree Celsius

Why we use MGO Sulphate board?

For the traditional mgo board with Mgcl2, some customers will have the problems of sweating and screw rusty. In fact, these problems are not caused by MgCl2, but the free Chloride Ion that left in the boards.

Normal mgo board is formed by the reaction of Magnesium Oxide and Magnesium Chloride, but normally, the reaction cannot be 100% taken, which means that some free Chloride Ions will be still left in the board. As to the free Chloride Ions, they will be easy to absorb moisture from the air and form water drops on the board surface (sweating problem), when the circumstances are very wet (high humidity). If this mgo board used with steel, the free Chloride Ion, water and steel will take reaction, and make the product rusty. But, if this board is exported to the dry places, it won’t have the problem, since it cannot absorb water from the air. That is why some places have this problem, while other places are ok.

For our new mgo board, we use MgSO4 to replace MgCl2 to do the production, which means that it is free of chloride. So, the problems referred above won’t happen on our new boards
