What Is Magnesium Wall Board
Composition and Sourcing
Magnesium wall board is a good choice for green building. It is made from magnesium oxide. This comes from seawater or old brine pools. Places like the Mediterranean Ridge have lots of magnesium chloride. These deposits are very pure. That makes them great for making magnesium oxide boards. Magnesium oxide is mixed with fibers like fiberglass or wood. This makes the board strong and light.
Magnesium oxide sheathing board does not have dangerous chemicals. It is safe and non-toxic for use inside buildings. Builders like it because it helps keep indoor air clean. It also lowers the amount of bad chemicals in the air.
Magnesium oxide boards help green building by using things that can be replaced. They also make less waste. Some boards use algae, which helps them stay dry. Using algae also helps use up waste from the environment. This makes the board’s structure tighter. It supports better building for the planet.
Manufacturing Process
Making magnesium oxide boards uses less energy than other materials. Workers heat magnesium carbonate or magnesium chloride to get magnesium oxide. This needs lower heat, between 550°C and 800°C. That saves energy compared to making Portland cement.
Property/Aspect | Description/Value |
|---|---|
Manufacturing Process | Exothermic reaction of MgO and water produces magnesium hydroxide as a binding matrix |
Energy Consumption | 2415 MJ/ton (MgO) vs. much higher for cement |
Carbon Capture | Absorbs CO2 during curing, forming hydrated magnesium carbonates |
Durability | Carbonation increases strength and reduces porosity |
When the board cures, it takes in carbon dioxide from the air. This helps lower greenhouse gases. It also makes the board stronger. Magnesium oxide boards last a long time and keep their good features. They do not burn easily and stop mold and mildew. This makes them a good pick for building. Magnesium oxide sheathing board also keeps heat in. This helps keep rooms warm or cool and saves energy.
Magnesium oxide boards stay safe and non-toxic as they age. They do not let out bad gases, even when they get hot. The boards are light and easy to put up. Builders like magnesium oxide sheathing board because it is strong, safe, and good for the earth.
Material Comparison
Magnesium Wall Board vs. Drywall
Magnesium wall board is a greener choice than drywall. Builders like magnesium oxide sheathing board because it uses natural materials. These materials can be recycled. Drywall uses more chemicals and is not as good for the earth. Magnesium oxide boards are better for the environment when made. They use less energy and do not give off bad gases. Drywall needs more energy and chemicals, which is worse for nature.
Feature | Magnesium Oxide Sheathing Board | Drywall (Gypsum/Cement Board) |
|---|---|---|
Composition | Natural, recyclable materials | Chemical additives, less eco-friendly |
Durability | High durability, resists impacts | Prone to cracking over time |
Fire Resistance | Excellent, up to 4 hours | Good, but less than MgO |
Moisture Resistance | Prevents mold and water damage | Absorbs water, may need sealing |
Cost | Higher upfront, lower upkeep | Cheaper, more maintenance |
Installation Ease | Lightweight, easy to install | Heavier, special tools needed |
Environmental Impact | Low, recyclable, no VOCs | Higher, some recycling efforts |
Magnesium oxide sheathing board costs more at first. But it saves money later because it lasts longer. It does not need as many repairs or replacements. Builders think magnesium oxide boards are easier to put up. They are lighter than drywall. Drywall is heavy and needs special tools, which slows down work.
Magnesium wall board is a good choice for green building. It helps the planet by using less energy and making less waste.
