Magnesium Oxide board "MgO board" is a factory-made, non-insulating sheathing board product. It can be used for a number of applications including wall and ceiling linings, fascias, soffits, tile backing and underlayment. MgO as a type of sheathing board (sort of like drywall or cement board) but with much-improved characteristics such as fire resistance, weather ability, strength, resistance to mold, mildew, and so on.

Features of magnesium oxid board:
1. Normal MgO board: one smooth, one rough surface;
2. Pasted with wall paper;
3. Coated with latex paint;
4. Glued with ceramic tile;
5. With a design of wood or water or other grain.
Appilications for mgo boad:
In many applications, MgO boards can be used in the same ways as gypsum and Portland cement sheathings. The substitution is not fully direct in terms of sheet thicknesses, fastening methods and joint treatments, but is very similar.This makes MgO board an easy product to use.The possible uses of MgO board are vast,and some of them include:Firewalls.Partitions.Structural sheathing for wood or metal stud walls.Shower stall tile backer board.Facings for structural panels engineered to use MgO as the facing.Shaft liners.Ceilings.Soffits.Fascia.Substrates for coatings and insulated systems (such as Direct-Applied Finish Systems, EIFS, and stucco).
