Material Basics

Magnesium Oxide Sheathing StructureWhat Is Magnesium Wall Board?

Mgo board is used in many new buildings. It is made from magnesium oxide, magnesium chloride, perlite, and vermiculite. These materials help mgo board stop fire and water. Mgo board does not burn fast. It does not soak up water. It also helps keep the air inside clean.

Each part of mgo board helps with fire resistance in a special way:

Component

Contribution to Fire Resistance

Magnesium Oxide (MgO)

Gives strong fire resistance and makes the board tough.

Magnesium Chloride (MgCl2)

Holds the board together when there is a fire.

Perlite

Keeps heat from moving through the board.

Vermiculite

Gets bigger when hot, so it blocks fire better.

There are new kinds of mgo board, like magnesium sulfate boards and magnesia cement panels. These boards can stop fire for up to 3 hours. They also keep water out. Mgo board stops mold from growing. When you pick mgo board, you help the earth. Makers use green ways and recycle extra magnesium.

What Is Fiberboard?

Fiberboard is found in furniture, floors, and wall panels. It is made from wood fibers and glue. Fiberboard is easy to cut and shape. It costs less and has a smooth surface. You can paint it or put other finishes on it.

Fiberboard is made in steps. First, wood chips are turned into pulp. Next, glue is mixed in. Then, heat and pressure press everything together. The table shows how each step changes water resistance:

Manufacturing Process

Description

Effect on Water Resistance

Defibration

Wood chips become pulp.

Good fibers help block water.

Adhesive Combination

Glue is added to the pulp.

The glue you pick changes water safety.

Thermocompression

Heat and pressure press the mix together.

This step makes the board strong and affects water soaking.

Fiberboard can get bigger or weaker if it gets wet. It works well in dry places. Mgo board is better where there is water or fire danger. Mgo board gives more safety. Fiberboard lets you make many designs.
