In case you haven't heard, there's a new multi-purpose building material available nationwide across the U.S. MagPanel® is a versatile, eco-friendly Magnesium Oxide Board, also called magnesium oxide panels or MgO panels, with a wide range of construction applications beginning with the inside for wall, ceiling and subflooring (for example tile backer), and outside for exterior trim, to roof decking and lap siding.
Magnesium oxide wallboards are factory-produced, non-insulating sheathing board products that are used for various construction applications.
MgO board is made from magnesium oxide. Magnesium oxide is a type of mineral cement, and contains magnesium (which has a chemical symbol of Mg) and oxygen (chemical symbol of O). Magnesium oxide panels are similar to drywall or cement board, but is stronger, fireproof, and has a higher resistance to mold, mildew, moisture, and weather.
MgO board is water-resistant but should not be directly exposed to the elements.

MagPanel® eliminates many challenges consumers, architects, builders, contractors and engineers face with residential, commercial and industrial construction. It comes in many different densities and strengths making it suitable for different applications and uses. It is used to replace a variety of other building materials including pressed board, gypsum board, oriented strand board (OSB), plywood, and cement board.
Ambient’s MagPanel® is a technologically advanced, high performance, fully recyclable board used to replace gypsum drywall, fiber cement wallboards, OSB or plywood. The board’s resistance to mold, mildew, fungus and extreme environmental exposure makes it the perfect building material for health-conscious builders and families.
MagPanel® gains its strength and resistance from very strong bonds between magnesium and oxygen atoms that form magnesium oxide crystals (with the chemical formula MgO). MagPanel® is a mineral based green building material. MagPanel® has high moisture resistance and repels mold, mildew and other fungal health hazards. This also means no warping, swelling, or rot when exposed to water or other elements. Because it is resistant to extreme cold or heat, construction can take place in virtually any environment, at any time, and in any season.
MagPanel® is a strong, high quality, fireproof, mineral-based building material used to replace plywood, fiber cement panels, OSB and gypsum wallboards. It is an extremely versatile product for use with interior and exterior construction. It is mading from bonding certain elements (including magnesium and oxygen) which results in an extremely strong cement-like material. Similar compounds have been used for construction purposes for hundreds of years in such world-famous sites such as the Great Wall of China, Rome's Pantheon, and extensively throughout one of the world's tallest buildings, Taipei 101.
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.
MagPanel® is a unique, cost-effective building material available across the U.S. The product has been engineered to resolve some of the toughest building challenges faced by architects, contractors, installers, builders and consumers.

MagPanel® offers many cost benefits. Because of its strength and durability MagPanel® increases the lifespan of structures such as homes and buildings. The cost per sheet of MagPanel® MgO Boards for the same thickness is greater than regular gypsum but the same or less than specialty types and generally less than most cement products.
With MagPanel® you pay a small premium for a huge increase in versatility and applications of magnesium oxide board. Additional cost savings are found in the installation of MagPanel® because the time to finish the boards can be much less and less product is needed in many applications. In addition, MagPanel® MgO boards are strong enough to support light shelving, pictures, etc., meaning no need to pre-install backing supports or use more expensive anchors. MagPanel® MgO boards are completely recyclable can also be disposed of easily. There are no expensive fees such as with the recycling/disposing of gypsum board scraps. Use leftover MagPanel® for a variety of indoor and outdoor projects, such as edging the landscaping, installing shelving, or excess material can be ground up and added to the soil as a nutrient.
When comparing building material costs consider the benefits and features offered by each product. This includes the upfront costs but also the savings recognized during the life of the product. MagPanel® MgO Boards provide a cheaper lifetime cost and a similar installation cost to gypsum when all the expenses are considered.Cost benefits of MagPanel®
The possibility of expansion for MagPanel® is low however there is some hydrothermal movement. You can leave smaller gaps to accommodate for lower expansion or shrinking. MagPanel® is highly resistant to extreme outdoor environmental exposure such as rain and strong winds as long as it is properly coated.
No. MagPanel® is considered mmoisture resistant, however during periods of extended exposure, moisture can affect it and it will experience hydrothermal expansion. When used outdoors, Magpanel should be covered or coated to protect it from the elements.
It is made by combining the carbon out of magnesium carbonite; commonly called “MgO” due to its chemical composition of magnesium (chemical symbol Mg) and oxygen (chemical symbol O). When oxygen is combined with magnesium under heat and pressure, it can produce a stone-like material: MgO. It is ground up into a powder, which is then combined with water to make a cement-like (adhesive) material. MagPanel® also contains other components but MgO is the primary component.
Pure magnesium, in its raw form, burns. MgO, however, is completely nonflammable and is used for fireproofing.
The chloride content of our MagPanel® is regulated during our manufacturing process and our boards average approximately 8%. Additionally, our dissolvable (free) chloride ion content is less than 5% and our sulfate content averages 0.2%. This is not to be confused with the Magnesium Chloride content, which is 40%.
MagPanel® MgO boards are made from natural minerals: magnesium oxide, chloride, and sulphate (otherwise known as Epsom salts) along with wood dust, (cellulose) perlite or vermiculite, and a glass fiber mesh. There are no volatile organic compounds or toxic ingredients. Caution: while the materials used are not harmful, it is strongly recommended everyone wear proper silica/concrete dust respirators when using MagPanel® due to the dust created while cutting and sanding.
MagPanel® can be stored easily indoors. It is highly resistant to moisture, and humidity making it easy to store. MagPanel® should be stored inside in a cool dry place as with any sheet building material. To protect the edges and corners, carry boards on their side. Stack boards flat on dunnage, loose wood, matting or other material and not directly on the ground. Do not allow MagPanel® to bow. Do not stack any other materials on top of MagPanel®. Before installing MagPanel® acclimate the panels for 48 hours in the room where they will be installed.
Finish MagPanel® with most products such as paint, stucco, synthetic stucco, wallpaper, plaster, stone, tile, brick and much more. The strong adhesion properties of MagPanel® also make it a perfect product for Structural Insulated Panels (SIPS), Exterior Insulated Finish Systems (EIFS) and interior wall systems using fabrics.
To finish MagPanel® MgO boards after installation, begin with a primer. This is required because MagPanel® panels are alkaline in nature. We recommend using a primer that is suitable for concrete or masonry. There are a few popular brands of paint which react molecularly with the cement in MagPanel® forming a UV highly resistant coating that will last for years. Acrylic stucco topcoats or polymer modified cement base coats can also be used and individually applied to the board. Test the topcoats and paints prior to completing the entire project. To properly test the bonding capability of the topcoat, brush on or spray a small area of the MagPanel® with paint, let the board dry and cure. Then make an X with a sharp razor knife, apply masking tape over the cut and press firmly and rip it off like a band-aid. If the paint stays on the board, this indicates the paint and board have a successful bond.
When installing panels, leave a 3 to 6mm wide gap between the panels. Control the depth of the gap using polyethylene backer rods to the point where the width is greater than the joint depth. Use non shrinking paintable caulk applied with a caulk gun, then smooth off excess caulk using a little water and your finger or a caulk smoothing tool. Add a coat of primer when the caulk is cured. After priming, apply a thin coat of spackle or gypsum mud to remove any joint telegraphing. The outside corners of the boards can be glued, sanded or routed smooth and flush and filled with caulk, plaster or grout. Use glue on the inside corners of the boards or butt joint with a bead of painter’s caulk.
The outside corners of the joints can be butted together and then sanded smooth. For a bull nose finish, corners can be routed or mitered. Adding a corner bead of caulk is optional. MgO bonds well to itself, metal, wood and other materials. Apply adhesive to the corner board joints using using ChemLink M1 or a moisture cure urethane adhesive. Review the caulking chart for other tested products.
Ceilings: For ceilings where the board will be fastened by screw to light gauge steel or wood use 8mm or thicker. Use a thicker board if planning to countersink the screw head. For drop down ceilings using MgO as panels, use 2mm or 6mm.
Walls: For most walls a board that is 10mm to 12mm is common. For walls requiring greater fire and impact resistance use a board that is 15mm to 20mm thick.
For walls that have continuous backing, cement or rigid insulation, a thinner board can be used. This is important when weight is a concern. For example, trailer homes have used 6mm as fully supported wall covering boards.
For applications where more strength is needed such as sports courts, or where sound reduction is needed, or for use to support bar countertops, use a thicker board at 20mm.
A few things can cause micro cracking in magnesium oxide boards such as structure movement caused by force from wind or earthquake. Or the structure may expand caused by thermo graphic or hydrometric expansion. The frame used under the boards may change as wood will shrink when dried and metal expands when heated. MagPanel®s shrink during curing and drying to ambient humidity and will have some movement due to thermal or moisture changes. Micro cracking becomes a negligible issue because most interiors maintain relatively even temperatures.
To address and or prevent micro cracking follow a few precautionary steps. First, before installation, allow the boards to acclimatize in the structure where they will be used. Leave a small space between boards and apply a non-shrinking caulking followed by a primer coat of paint. Apply spackle or plaster to hide any imperfections. Finish by using a paint designed to prevent moisture absorption. Isolate joints from the structure by splicing with strips of scrap MgO Board or metal clips to keep the joints between studs.
To fasten MagPanel® panels, use corrosion resistant fasteners. Add extra support by applying a barrier coat of epoxy, ceramic or a similar adhesive. Drywall screws that have a stainless steel or phosphoric coating also work well with MagPanel® panels. For easiest installation, choose screws with self-counter boring heads. Alternatively, use gun nails when applying to both wood and light gauge steel framing with the appropriate pins or nails.
To finish MagPanel® joints, use any top-quality joint compound. Check with the manufacturer of the product to ensure it is compatible with MagPanel®. Use finely ground hydraulic cement fillers such as RapidSet One Pass to establish industrial strength joints. Additionally, urethanes bond well to MagPanel® panels. If using tape and mud is a preference, choose a self-adhesive fiberglass tape and a mud or plaster suitable for moist environments. Most lightweight pre-mixed mud does not like moisture and MagPanel® MgO Boards can have moisture, but they will eventually equalize with the structure.
MagPanel® MgO Boards bond well to itself, metal, expanded polystyrene, wood, and laminates using ChemLink M1 or another moisture cured urethane adhesive.
The density of MagPanel® is around 1 gram per cubic centimeter or just over 2.2 pounds per square foot for 12mm (1/2 inch) board – They are typically heavier than gypsum and lighter than ordinary cement boards.
For optimal results cutting MagPanel® panels, use a thin carbide circular saw or worm drive saw. Rout the edges using carbide tooling. If the construction project is a large project, consider using a diamond bit. MagPanel® panels can be scored with a razor blade and snapped apart from the smooth side. This method does not provide as clean an edge and will require more finishing work. To prevent micro cracking with cuts, glue all corners together.
MagPanel® MgO Boards are ideal for use as a sub floor. Additionally, boards are available in the correct thickness and strength for use as structural sheathing. To determine the proper board grade depends on the design of the floor, joist span, spacing and size, dead load and live loading factors.
When it comes to fireproof magnesium oxide boards, there are two types: MgSo4 (magnesium sulfate) and MgCl (magnesium oxide). To understand the differences between the two, take a look at what each kind of board is composed of:
There are two things to take note of when it comes to the composition of these two panels. First, the presence of magnesium sulfate vs. magnesium chloride and second, the level of dissolvable chloride content.
As you can see in MgSo4, magnesium sulfate replaces the magnesium chloride in MgCl. So, if you're not a chemist like us, you're probably wondering what that means. Simply put, the magnesium sulfate makes the MgSo4 panels incredibly water-resistant, by preventing moisture from absorbing back to the halogen in the board.
This contrasts with how magnesium oxide (MgCl) boards were produced in the past, which resulted in “weeping boards” and corrosion of metal fasteners. The next evolution of magnesium oxide boards is magnesium sulfate (MgSo4 aka MagPanel) boards. Due to these advances in manufacturing, when you purchase MagPanel, you don’t have to worry about "weeping boards."
Despite having a few compositional disparities, MgSO4 and MgCl panels generally share similar characteristics, which primarily include:
Magpanel® has a wide variety of uses, and both MgSO4 and MgCl can be used for the following applications:
Although MagPanel® is heat and moisture resistant, it should be stored inside in a cool dry place as with any sheet building material. To protect the edges and corners, carry boards on their side. Stack boards flat on dunnage, loose wood, matting or other material and not directly on the ground. Do not allow MagPanel® to bow. Do not stack any other materials on top of MagPanel®.
MagPanel® is a multipurpose board used inside for walls, floor, ceiling, tile backer board and also outside for sheathing, roof decking and lap siding. Depending on how the board is used and the thickness of the board being used, will dictate what tools may be needed.
Remove the packaging and allow the MagPanel® panels to acclimate to the room temperature and humidity for 48 hours. Ideally, the boards should acclimate in the room where they will be used with the temperature replicating the planned temperature of the room.
Placement varies depending on the application of the boards. When attaching to cold-formed steel framing (CFS), stagger panels with a 1/16” (1/5mm) gap between boards. When attaching to wood allow 1/8” gap.
MagPanel® is constructed with one side smooth finish and one side rough finish. The rough finish can be used as a backer board for tile and other applications.
When laying resilient flooring such as Luxury Vinyl Plank, Bamboo Flooring, Eucalyptus Flooring, Vinyl plank or Linoleum over MagPanel®, fill with a polyurea or modified epoxy seam filler and shave or sand until flush. This helps create a smooth surface and avoids “telegraphing” which is uneven joints to on the wear surface.
MgO board is a non-toxic board material and certain types of fasteners may corrode the board. Because all projects and locations are different, consult a local fastener expert for your location and project. Ambient recommends using a 316-stainless steel material for all fasteners. Alternatively, a ceramic coated fastener designed specifically for cement board products may also be acceptable.
MagPanel® does not contain any carcinogenic material. We do recommend that installers wear a dust mask and safety glasses during routing, cutting and sanding operations. Never dry sweep MagPanel®, instead use a wet suppression or HEPA vacuum.
If you are using galvanized steel framing, the chlorides in some MgO sheathing, used to ward off insects and prevent the feeding of mold and mildew, may experience a reaction. There have been no reports of such reactions. If using MagPanel® as a sheathing, we recommend installing a barrier of some type to eliminate direct contact between the board and the framing.
Be sure to always follow local, state and national building codes with your construction projects.
