Understanding MgO Boards and Gypsum Boards

What Are MgO Boards?

MgO boards, or magnesium oxide boards, are strong building materials. They are made by heating magnesium and oxygen together. This forms magnesium oxide, which becomes hard like stone. To make them stronger, manufacturers mix MgO powder with water, salts, wood dust, and other materials. This special mix gives MgO boards their strength, fireproofing, and mold resistance.

MgO boards can be used for walls, ceilings, and floors. They don’t absorb water and resist mold because they are non-organic. This makes them perfect for damp areas. Unlike other materials, MgO boards stay strong even in tough conditions. They are a great choice for long-lasting construction projects.

What Are Gypsum Boards?

Gypsum boards, also called drywall, are common for walls and ceilings. They have a gypsum core covered by paper or fiberglass. These boards are light, simple to install, and affordable. This makes them popular for homes and offices.

Gypsum boards are tested to meet building standards. Here are some important tests:

Gypsum boards are treated to fight mold but have organic parts. This makes them weaker against water compared to MgO boards. They work best in dry areas where cost and easy setup matter most.

Mold Resistance: A Detailed Comparison

Why MgO Boards Are Mold Resistant

MgO boards are great at stopping mold because of their makeup. They are fully inorganic, so they don’t rot or feed mold. This makes them perfect for places with lots of moisture. MgO boards scored 0/0/0 on the ASTM G21 test, showing they block fungus growth.

Their surface barely absorbs water—only 0.34%. This stops water from getting inside and causing harm. Unlike other materials, MgO boards don’t swell, bend, or break when wet. They stay strong and mold-free, even in humid areas. Plus, they resist pests and mold, making homes safer and healthier.

Mold Resistance in Gypsum Boards

Gypsum boards are treated to resist mold but don’t do as well in wet spots. Paper-faced gypsum boards can soak up water, which helps mold grow. Over time, this can cause swelling, bending, and damage.

Fiberglass-faced gypsum boards handle moisture better since they don’t have paper. But even these boards can’t beat MgO boards in mold resistance. Tests like ASTM D3273 show that gypsum boards, especially with paper, struggle in damp places.

Here’s a simple comparison of mold resistance:

When picking one, think about the location. In wet areas, MgO boards work better and last longer.
