Comparison with Traditional Boards

You may ask how mgo sheathing board is different from gypsum or cement boards. Mgo sheathing board does not burn and stays strong in heat. Gypsum can break and let out bad stuff when hot. Cement boards do well in fire but are heavy and hard to move.

Let’s look at these boards:

Material

Fire Resistance Characteristics

Structural Integrity During Fire Exposure

MgO Boards

Non-combustible, high fire ratings, maintains integrity under high temperatures

Excellent resistance to bending, cracking, and collapsing

Gypsum

Limited fire resistance, may degrade under heat

May lose strength and emit harmful substances

Cement

Non-combustible, highly fire-resistant, maintains integrity for up to 2 hours

Strong performance under fire exposure

Mgo sheathing board also stops mold and damage better than gypsum. You can use mgo sheathing board in bathrooms, kitchens, and busy places. Gypsum works best in dry rooms. Cement boards are good for wet places but are harder to install than mgo sheathing board.
