What is MgO Board and Why It’s Gaining Popularity
MgO boards are among the most revolutionary building materials we've seen in recent years. Anyone researching building materials has probably come across these versatile panels that builders use in both homes and commercial buildings.
What is MgO board made of?
We make MgO boards mainly from magnesium oxide, magnesium sulfate (in the newest versions), and various reinforcing materials. The process combines calcined magnesium oxide with magnesium sulfate brine and reinforcing materials like fiberglass mesh, perlite, and wood fibers. These ingredients mix into a slurry that forms panels and then cures.
The board's main ingredient—magnesium oxide—comes from natural minerals like magnesite. We heat these minerals to high temperatures to create a reactive powder. This powder establishes the board's structure and gives it incredible strength and durability.
New chloride-free formulas now use binding agents like magnesium sulfate instead of magnesium chloride. These changes make the boards last longer and eliminate any worries about corrosion.
Key differences from traditional drywall
MgO boards work better than regular gypsum-based drywall in several ways:
Superior moisture resistance - MgO boards stay strong even when wet, unlike drywall that falls apart with water exposure.
Enhanced fire resistance - These boards don't burn and can handle much higher temperatures than gypsum products.
Greater impact resistance - The reinforced structure makes MgO boards much more challenging against impacts and daily wear.
Mold and pest resistance - Magnesium oxide's alkaline properties naturally stop mold growth and keep insects and rodents away.
Environmental benefits - Most MgO boards don't need toxic additives, and you can recycle them completely, unlike most drywall.
Regular drywall has paper facing that lets mold grow. MgO boards create conditions where biological contaminants can't survive. This makes them perfect for wet areas like bathrooms and kitchens, where normal drywall would fail quickly.
Why chloride-free matters in 2025
The building industry has moved toward chloride-free MgO formulas for several key reasons:
Corrosion prevention leads the list of reasons for this change. Old-style MgO boards with magnesium chloride can release chloride ions when they get wet. These ions might corrode metal fasteners, framing, and electrical parts nearby as time passes.
Longevity concerns showed up in early MgO board installations. Some boards with chloride started breaking down after a few years. Chloride-free formulas fix these problems and last much longer.
Evolving regulations now look more closely at chloride in building materials. Building codes keep getting stricter about how durable materials must be. Chloride-free options help builders meet these rules now and in the future.
Climate resilience matters more as extreme weather becomes common. Chloride-free boards work well even in humid places and coastal areas where salt in the air makes traditional boards corrode faster.
Many manufacturers now market their chloride-free formulas as top-tier products. Some have stopped making chloride-containing products altogether. This change shows more than just a trend—it points to a fundamental shift in building material science that focuses on lasting performance and sustainability.
Performance and Safety Benefits of Chloride-Free MgO Boards
Chloride-free MgO boards are becoming a top choice in residential and commercial construction. These boards outperform traditional building materials in many ways, which explains their growing popularity in the market.
Fire resistance and certifications
Fire safety stands out as one of the most significant advantages of chloride-free MgO boards. These panels won't burn and have earned Class A fire ratings through strict testing. Premium boards can withstand temperatures up to 2200°F without burning.
Notable certifications include:
ASTM E119: One and two-hour fire ratings
ASTM E84: Zero flame spread and minimal smoke development
ASTM E136: Meeting acceptance criteria as a non-combustible material per IBC 2021
These boards don't need extra tapes, sealants, or treatments to achieve their fire ratings, unlike gypsum products. The boards char instead of burning during fires. They absorb heat and slow down fire spread. This natural fire resistance makes them perfect for shared walls, exterior uses, and areas where safety comes first.
Moisture and mold resistance
Chloride-free MgO boards work great in wet environments where regular materials would break down faster. These boards keep their shape and strength even after getting wet multiple times. Tests show that high-quality MgO boards barely lost any flexural strength after 25 wetting-drying cycles. OSB lost 40%, plywood 9%, and gypsum between 36% and 52%.
These boards are completely inorganic, so they create an environment where mold, mildew, and fungi can't grow. This makes them an excellent choice for bathrooms, kitchens, basements, and places with high humidity.
Durability and structural integrity
Chloride-free MgO boards are incredibly strong because of their unique makeup. They resist scratches, punctures, and impacts better, which makes them perfect for high-traffic areas.
Quality chloride-free boards kept their strength even after 60 weeks in 90% humidity. Without chloride, these boards avoid the corrosion problems that affect regular MgO boards, and they last much longer. The boards might cost more than drywall at first, but you'll save money over time because they need fewer repairs and replacements.
Environmental impact and recyclability
Chloride-free MgO boards are better for the environment. Making MgO cement panels produces about 37.3 kg CO2 eq/m², which is 22% less than Portland cement concrete. Using natural gas instead of coal cuts carbon emissions by another 18%.
You can recycle these boards completely when they're done being used. The magnesium can be extracted and used again in other industrial applications. You can also crush the boards and use them to improve soil quality without harming the environment.
These boards create healthier indoor spaces because they don't contain formaldehyde, asbestos, silica, or other harmful substances. This is especially helpful if you have allergies, asthma, or chemical sensitivities.
