Magnesium Sulfate Sheathing and Other Materials

What is Magnesium Sulfate Sheathing

Magnesium sulfate sheathing is used in many new buildings. This panel is made with different materials to make strong walls. It has magnesium oxide, magnesium sulfate, wood dust, perlite, and glass fiber mesh. People mix magnesium oxide and magnesium sulfate with water to make a thick paste. They add wood dust and perlite next. Glass fiber mesh goes into the mix. Workers pour the mixture into molds and press it flat. The boards dry in special rooms. These mgo sheathing boards stop fire, water, and mold. Magnesium oxide sheathing lasts longer than most other panels. Builders pick magnesium oxide boards because they are strong and safe.

• Magnesium oxide sheathing gives you:

  • Very good fire protection

  • Does not soak up much water

  • Stops mold from growing

  • Stays strong for a long time

What is OSB

OSB is used a lot in building walls. OSB means Oriented Strand Board. This panel is made from wood strands glued together with resin. The strands are placed in certain ways to make it strong. OSB works for walls, floors, and roofs. You can see how OSB is used in the table below:

OSB is cheap and works well as a sheathing panel. It can hold heavy things and does not get ruined by water easily. Builders use OSB for many parts of buildings.

What is Plywood

Plywood is a sheathing panel you may know. Plywood is made from thin wood layers glued together. Each layer’s grain goes in a different direction. This keeps plywood from bending or twisting. Plywood’s layers make it strong. The grains going different ways help stop splitting and give even strength. Plywood is strong but not heavy. Builders use plywood for walls, floors, and roofs.

Tip: Plywood is good when you need exact sizes and strong support.

Unique Properties of Magnesium Sulfate Sheathing

Magnesium oxide boards are special because they stop fire and water. These mgo sheathing boards last longer in hard places. Magnesium oxide sheathing does not bend or rot like wood panels. You can use magnesium oxide boards where it is wet or there is a fire risk. Builders pick mgo sheathing boards for safety and strength. This panel helps keep walls safe in new buildings.

Durability and Strength of MgO Sheathing Boards

Structural Performance

You want walls that stay strong for a long time. Magnesium oxide sheathing is tough and lasts many years. These boards are stronger than wood panels in many ways. They do not lose their shape or strength when wet or under heavy things.

Here is a table that compares magnesium oxide sheathing to other panels:

Magnesium oxide boards keep a flexural strength above 14 MPa, even when wet. You can count on these boards in hard situations. OSB and plywood are not as strong, especially if they get wet.

You might wonder how these panels handle hits and heavy weight. Look at this table:

Magnesium oxide sheathing is very strong and does not wear out fast. These boards work well in busy places or where people walk a lot. Plywood does not bend or split easily, so it is good for holding up weight. OSB is strong for its weight, but water can make it weaker.

Note: Mgo sheathing boards keep their flexural strength after many wet and dry cycles. OSB loses about 40% of its strength, and plywood loses about 9%. Magnesium oxide boards almost do not change.
