1/8 in MagPanel MgO Board

MagPanel® is a strong, high quality, fireproof, mineral-based building material used to replace regular MgO boards, plywood, fiber cement panels, OSB and gypsum wallboards. It is an extremely versatile product for use with interior and exterior construction. It is made from bonding certain elements (including magnesium and oxygen) which results in an extremely strong cement-like material.

Expansive deposits of magnesium oxide can be found in China, Europe, and Canada. The great White Mountains in China have so much natural MgO, it is estimated there is enough to last another 800 years at today's rate of consumption. Thus, MagPanel® is an incredible building material with seemingly unlimited uses. It can be used in place of drywall, and some of the many applications include sub-flooring and tile backer, ceilings, walls, exteriors, soffits, sheathing, coding substrates, shaft-liner, bathtub enclosures, and exterior siding. When used for exterior projects it must be coated or protected from the elements.

MgO board is harder and stronger than drywall, and it is resistant to fire, insects, mold, mildew, and rot. It is sound and impact resistant, and has good insulating characteristics. It's noncombustible and non-toxic, has a receptive bonding surface, and contains no dangerous toxins like some other building materials. One exciting characteristic about Magnesium board is that it's lightweight while still being very, very strong. Therefore, a smaller amount of MgO board can do the same job (or better) as a greater amount of another material, such as sheetrock. And don't forget, because MgO board is so moisture-resistant, it lasts a very long time. The Great Wall of China is a perfect example of that!

Magpanel® can be sawed, drilled, router-shaped, scored and snapped, nailed, and painted. It's many uses in the construction field include fireproof materials for ceilings and walls in every type of construction including apartment complexes, theaters, airports, hospitals, and much more.

This amazingly versatile product also happens to be very green (environmentally friendly – not the color green). It has no ammonia, formaldehyde, benzene, silica, or asbestos, and it is completely safe for humans. It's a natural product that can be completely recycled, so it leaves a very small carbon footprint, and has no negative impact on landfills.

MagPanel® is available in a variety of sizes and thicknesses, it comes in a choice of basic colors and textures, and there are different grades and strengths to choose from, depending on the application. Because it is so hard, there is no need to place joints on a stud. And because it is so stiff, thin boards can be used in place of thicker boards of another material.

Absolutely. Magpanel is exceptionally fire-resistant, offering robust protection against fire hazards, making it ideal for use in areas prone to fire risks.

Magpanel holds an A1 Fire Rating, demonstrating its superior fire resistance. It has been rigorously tested to withstand temperatures exceeding 750°C (1,382°F) for over 30 minutes without any discoloration. This exceptional performance has earned Magpanel the esteemed classification of A1 fire rating in accordance with EN 13501-1+A1:2010, clause 12.

Magpanel is also certified under EN ISO 1716 and EN 13501, ensuring compliance with stringent fire safety standards and providing customers with peace of mind regarding its fire-resistant properties. You can review our fire rating test results on our combined testing document.

Understanding the Base:

Both MagPanel and standard MGO boards start with magnesium oxide (MgO) as their core ingredient. Here's how it's made:

• Magnesium carbonate is heated, removing carbon and leaving MgO behind.
• This MgO is formed into a strong, stone-like material, ideal for construction.

The Key Difference: Magpanel contains magnesium sulfate, regular MGO Boards contain magnesium chloride

• MagPanel:

  • Magnesium Sulfate is the primary secondary ingredient, prevents moisture issues and is eco-friendly.
  • Minor Components: Perlite, wood fiber, and fiberglass mesh for additional strength and stability.

• Regular MGO Boards:

  • Magnesium Chloride is the primary secondary ingredient; functional but can lead to moisture and corrosion concerns over time, may result in "weeping boards", a result of corrosion that occurs as a result of the magnesium chloride interacting with metal fasteners and structural components.

Composition and Safety

Here's a simplified breakdown of MagPanel composition from the MSDS:

• Magnesium Oxide: ~50% (main structural component)
• Magnesium Sulfate: ~40% (key advantage of MagPanel)
• Other: Perlite, Wood Fiber, Fiberglass Mesh (~10% total)

Historical Context: MgO-based compounds enjoy a long history in construction, seen in structures like the Great Wall of China all the up to modern masterpieces like Taipei 101. MgO itself is non-flammable and often used in fireproofing.

Magnesium sulfate (MgSO4) MgO boards (MagPanel) and magnesium chloride (MgCl2) MgO boards differ primarily in the type of magnesium salt used in their manufacture. Magnesium sulfate boards use magnesium sulfate as the bonding agent, which is known for being less corrosive and more stable, thereby reducing the risk of moisture absorption and subsequent damage. Magnesium chloride boards, on the other hand, utilize magnesium chloride, which is more cost-effective but can be more susceptible to moisture, leading to a phenomenon known as "weeping" or "halo effect," where the chloride ions attract moisture, potentially causing corrosion of metal components in contact with the board.

While Magpanel might have a slightly higher initial cost per sheet compared to regular drywall, it offers several long-term cost benefits:

• Durability: MagPanel's strength and resistance to moisture, mold, and fire increase the lifespan of your structure, saving you money on future repairs or replacements.
• Versatility: MagPanel can be used in various applications, sometimes replacing the need for multiple specialized products. This can lead to overall project cost savings.
• Added Functionality: MagPanel's strength allows you to hang light shelves, pictures, and other items directly on it, potentially eliminating the need for additional wall reinforcement.

In Summary: Think of MagPanel as an investment. You pay a bit more upfront but gain significant value in terms of durability, versatility, and reduced maintenance costs over time.

Magpanel (magnesium sulfate boards) and magnesium oxide (MgO) boards are often used as substitutes for traditional drywall, offering several advantages:

Fire Resistance: One of the most significant advantages of Magpanel is it's exceptional fire resistance. Magpanel is non-combustible and can withstand extremely high temperatures without burning or emitting toxic gases. This property makes it suitable for use in fire-rated walls and ceilings, providing enhanced safety and protection compared to traditional drywall.

Moisture Resistance: Magpanel is highly resistant to moisture, mold, and mildew, making it ideal for use in damp or humid environments such as bathrooms, kitchens, and basements. Unlike gypsum-based drywall, Magpanel does not degrade or lose structural integrity when exposed to moisture, reducing the risk of water damage and mold growth.

Durability: Magpanel is known for its durability and resistance to impact, abrasion, and insect damage. Its less prone to denting, scratching, or crumbling compared to traditional drywall, making it suitable for high-traffic areas or commercial applications where durability is essential.

Dimensional Stability: Magpanel exhibits excellent dimensional stability, meaning it is less susceptible to expansion, contraction, or warping due to temperature and humidity changes. This property helps maintain the integrity of the wall or ceiling over time, reducing the need for repairs or replacements.

Environmental Considerations: Magpanel is considered environmentally friendly as they are composed of natural materials, including magnesium oxide and magnesium chloride/sulfate. It does not contain harmful chemicals or volatile organic compounds (VOCs), contributing to healthier indoor air quality. Additionally, Magpanel is recyclable and has a low carbon footprint compared to some other building materials.

Installation: While Magpanel is similar in appearance and installation to traditional drywall, it may require specialized cutting tools due to it's density. However, it is lightweight and easy to handle, simplifying the installation process for contractors and DIY enthusiasts alike. You can score MgO boards with a carbide-tipped scoring knife or a utility knife, but this process can be more labor-intensive.

Weight: Magpanel and Magnesium Oxide (MgO) boards are generally lighter than traditional cement boards, although their weight can vary based on thickness and density. Typically, a 12mm (approximately 0.5 inch) thick MgO board weighs between 1.5 to 2.0 pounds per square foot (psf). In comparison, standard drywall of the same thickness (1/2 inch) has a weight range of approximately 1.6 to 2.2 psf.

Flexural Strength: Magpanel and MgO boards are recognized for their superior flexural strength, typically falling between 7 to 15 MPa (megapascals) depending on the specific product and manufacturer. In contrast, standard drywall exhibits a lower flexural strength, generally ranging from 3 to 5 MPa. Although there are enhanced drywall products designed for higher impact resistance, their flexural strength usually remains below that of MgO boards, even if marginally improved.

Overall, Magpanel offers superior fire resistance, moisture resistance, durability, and environmental benefits compared to traditional drywall. While Magpanel may have a slightly higher upfront cost, its long-term performance and reduced maintenance requirements make it a cost-effective and reliable alternative for various construction applications.

No, MagPanel is made from safe, natural materials:

• Primary Ingredients: It's primarily composed of magnesium oxide and magnesium sulfate (Epsom salts).
• Other Components: A small amount of wood fiber, perlite or vermiculite, and a glass fiber mesh backing.
• No VOCs or Toxins: MagPanel is free of volatile organic compounds and other toxic ingredients.
• Controlled Chloride Content: We strictly regulate chloride levels during manufacturing to ensure they stay below 1%.

Important Safety Note: While MagPanel itself is safe, cutting and sanding creates dust. It's essential to wear proper silica/concrete dust respirators for protection during these tasks.

They are used in a variety of applications including interior and exterior wall sheathing, ceiling applications, fireproofing, and as a substrate for flooring and tiling.

MagPanel MgO Panels are sold in standard 4 × 8 ft sheets and in multiple thickness from 1/8" up to 1" (3mm to 25mm.) We maintain stock in some thicknesses and all other thicknesses are available with a 90 day lead times (minimum order quantities may apply).

MagPanel has a density of approximately 1 gram per cubic centimeter. Here's how its weight compares to other common materials:

• 12mm (1/2 inch) MagPanel: Around 2.2 pounds per square foot.
• Gypsum Board: Generally lighter than MagPanel of the same thickness.
• Cement Board: Typically heavier than MagPanel.

Key Point: While denser than gypsum, MagPanel's superior strength often allows you to use a thinner board, reducing the overall installation weight.

MagPanel is moisture-resistant but not waterproof. During periods of extended exposure, moisture can affect it and cause hydrothermal expansion. When used outdoors, it should always be covered or coated to protect it from the elements.

MagPanel is designed for resilience, but like all building materials, it's important to understand its behavior:

• Expansion and Contraction: MagPanel, like all structural MgO boards, will experience some slight movement with significant temperature or humidity shifts. This is why expansion gaps and flexible joint compounds are recommended during installation. Magpanel must also be acclimated to it's environment before it is secured or finished, and when finished indoors, humidity must remain stable to reduce expansion and contraction issues.
• Outdoor Resilience: MagPanel stands up well under weather conditions like rain and wind, but a proper coating is essential for protection.
• Freezing: MagPanel itself is freeze-thaw resistant. However, if it absorbs moisture before a freeze, some surface damage can occur. Proper sealing and moisture management are key in freeze-prone climates.

Tips for Optimal Performance

• Follow Installation Guidelines: Refer to the manufacturer's instructions for spacing and recommended sealants or coatings.
• Consider Your Climate: In areas with extreme temperature swings or high humidity, choose joint treatments and coatings designed to handle those specific conditions.

MagPanel offers significant benefits over these common building materials:

• Fire Resistance: MagPanel boasts impressive fire ratings, making it safer for a variety of applications.
• Moisture Resistance: It won't rot, warp, or succumb to mold like gypsum or plywood, especially in wet areas.
• Strength and Impact Resistance: MagPanel is less prone to dents and damage, extending the lifespan of your structure.
• Insect and Pest Resistance: It's unattractive to termites and other pests.
• Versatility: MagPanel excels in walls, ceilings, subfloors, countertops, and even some exterior applications.

Magnesium Oxide boards may be more expensive upfront than some traditional materials like gypsum, but their durability and resistance properties can lead to cost savings over time.

For standalone subflooring, we strongly recommend 3/4-inch (19mm) MagPanel. Here's why:

• Strength and Stability: This thickness provides superior rigidity and support, minimizing deflection and creating a solid base for your final flooring.
• Durability: 3/4-inch MagPanel stands up to the wear and tear of everyday living.
• Ease of Installation: While slightly heavier than thinner options, 3/4-inch panels are still manageable for most DIYers and contractors.

Absolutely! MagPanel aligns well with green building practices for several reasons:

• Natural Ingredients: Primarily made from magnesium oxide and magnesium sulfate (Epsom salts), which are abundant minerals.
• Low-Impact Production: The manufacturing process requires less energy and produces fewer emissions than traditional cement or gypsum board production.
• Durability: MagPanel's resistance to moisture, fire, and mold means less need for replacements, reducing waste over time.
• Recyclable: It's 100% recyclable at specific facilities, making it a responsible choice at the end of its lifespan.

Magnesium Oxide boards are considered to have low to no off-gassing, making them a safer alternative in terms of indoor air quality compared to some other building materials.

Yes, their moisture-resistant properties make them ideal for use in high humidity areas, protecting against mold, mildew, and water damage. However please note that Magpanel and MGO boards are not meant to come in direct contact with water so they must be fully finished.

They offer good sound insulation properties, making them suitable for use in walls and ceilings where noise reduction is desired.

MagPanel MgO boards generally have an R value between 0.20 and 0.40 per inch of thickness. This R-value reflects the material's thermal resistance, making it slightly more insulating than typical cement-based boards. While MgO boards are not primarily used for insulation, they do offer moderate thermal resistance compared to other construction materials.

MagPanel MgO boards provide better thermal resistance than cement-based boards. Cement-based boards typically have an R-value of around 0.05 to 0.20 per inch, making MagPanel MgO boards more effective in providing insulation. However, both materials are primarily chosen for their fire resistance, durability, and moisture protection rather than for insulation purposes.

Magpanel generally offers a similar or slightly higher R-value compared to traditional magnesium oxide boards. This is due to Magpanel's enhanced moisture resistance, which can help maintain its insulating properties over time. While the R-value difference is minimal, magnesium sulfate-based boards can offer improved performance in environments prone to humidity or moisture exposure.

While MagPanel MgO boards do provide some level of thermal resistance, they are not primarily used for insulation. Their main strengths lie in fire resistance, durability, sustainability, and moisture protection. For better insulation, MgO boards are often paired with other materials like foam insulation or fiberglass.

Yes, they are resistant to termites and other pests, providing an additional benefit in termite-prone areas.
