Magnesium Oxide Boards are the most eco-friendly multi-purpose building panels. This 3mm / 1/8" inch thick sheet is most commonly used as walls and ceilings.

We do not provide installation services but have no fear as there are many high-quality contractors in your state and the majority will be eager to provide a free estimate over the phone or in the comfort of your own home.  We recommend that you check out our helpful article titled 7 Tips For Choosing A Floor Installer.

If our website lets you add your desired quantity into the shopping cart without showing a "this item is back-ordered" pop up notification, that means the product is in stock and ready to ship!

We highly recommend reading our Shipping Policy for a comprehensive explanation of our shipping processes.

We ship most freight orders (over 125 lbs) out within 4 business days of purchase, the average being 2 business days. For faster shipment of freight orders, we offer an Expedited Shipping option at checkout however please note that this simply means that we will ship the order out the next business day - it does not shorten the transit time once shipped. For small parcel orders we offer express UPS shipping options at checkout as well; please note that for express shipping services the order must be placed by 2pm EST in order to ship out that same day, otherwise we will process the shipment the next business day.  We do not ship out orders, nor do the shipping companies deliver them, on weekends. 

For residential lift-gate freight order deliveries, once the flooring order arrives at the local freight terminal, they will call you to schedule your delivery appointment, which is usually a 2-6 hour window on the day of your choosing (weekdays only) when possible. All deliveries are curbside as the freight companies do not offer inside delivery.

MagPanel® is a strong, high quality, fire-proof, 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: 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.

Magboard 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.

Magboard 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.

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, use a thicker board at 20mm.

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.

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.

Pure magnesium, in its raw form, burns. MgO, however, is completely nonflammable and is used for fireproofing.

MagPanel® offers many cost benefits. Due to its strength and durability, MagPanel® increases the lifespan of structures such as homes and buildings. The cost per sheet of MagPanel® MgO Panels for the same thickness is greater than regular gypsum, but its the same-or-less than specialty types and generally less than cement products.

With MagPanel® you pay a small premium for a huge increase in versatility and applications of MagPanel®. 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 Panels are strong enough to support light shelving, pictures, etc. - meaning no need to pre-install backing supports or use more expensive anchors.

MagPanel® MgO Panels are completely recyclable and can 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.

We highly recommend you review our Shipping Policy, which has a lot of great information and a short video about the shipping process.  When your order ships out we’ll send you a notification email with all of your shipping information.  Once the shipment arrives at the local freight terminal near your delivery location, the terminal staff will call you to schedule a delivery appointment* (weekdays, usually a 2-6 hour window).  Make sure you don’t miss the delivery appointment or the freight company may charge a hefty re-delivery fee. *if you have selected commercial/freight dock delivery, freight may be delivered without needing an appointment

Once the order arrives, ensure you mark any damages you see on the driver’s bill of lading (they’ll then usually give you a copy).  You don’t have to open and inspect every item, just look at the outside of the pallet – that is where the shipping damage will be. Ensure you write the number of damaged items and detailed notes, then take photos of the damaged items and email all of this information to your Ambient representative to ensure we can ship out free replacements.

Important note: If your delivery location is located on a road that cannot be accessed by a semi-trailer truck, you may be required to pick the freight up at the local terminal or meet the driver at an intermediary location.

We accept the following payments:

1. All major credit and debit cards.

2. Personal and bank checks (please note there may be a 14-day shipping delay).

3. ACH payments. (contact your Ambient representative for bank account details)

4. Paypal. In fact, PayPal Credit offers financing. *During checkout select the PayPal option to log in and then select PayPal Credit

MagPanel® MgO Panels 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. The chloride content of our magboard 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%.

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® MgO Panels are sold in standard 4 × 8 ft sheets and in multiple thickness from 6mm to 20mm.

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 Panels 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.

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: 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 acclimate 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.

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.

None of our products are brought inside the delivery location by the driver.  All small parcel shipments are at the discretion and policy of the shipping company.  All freight shipments are curbside delivery with lift-gate unless you specifically request freight dock delivery.  Curbside delivery means they lower the pallet on the street at the end of the driveway. The drivers are not required to enter the property boundaries, although if not hazardous sometimes they’ll back up the driveway (if it’s flat and short) and drop the pallet on the driveway. 

Someone must be on-site to receive the delivery and inspect it for exterior damage, and then note any damage on the driver’s bill of lading (otherwise we can’t send free replacements). We highly recommend that you do not pay laborers to sit around and wait for the delivery, as the freight companies do sometimes miss appointments and they do not reimburse for such lapses. In some cases at the time of checkout, our website will allow you to add "Garage Delivery" for an additional fee, but this includes rolling the materials pallet into a carport or garage only, and terms and conditions apply.

No. MagPanel® is considered mmoisture resistant; however, during periods of extended exposure, moisture can affect it and cause hydrothermal expansion. When used outdoors, Magboard should be covered or coated to protect it from the elements.

The possibility of expansion for MagPanel® is low, but 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.

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 Panels can have moisture, but they will eventually equalize with the structure.

MagPanel® MgO Panels bond well to itself, metal, expanded polystyrene, wood, and laminates using ChemLink M1 or another moisture cured urethane adhesive.

While it can be a bummer if your shipment arrives damaged – it is not the end of the world! We can easily send you free replacements for anything that was damaged in transit - all we ask is that you do not refuse the shipment and mark any damages on the receipt provided by the driver. After that, please take a few photos of product while it is still on the pallet and email them to [email protected] so we can make a record on your account. Then, please examine the items further once you've brought them inside to determine the extent of the damage, and take photos of affected areas if you require replacements. Once we receive the details and photos we will send out the replacements right away. Most of the time, installers will be able to work around the damage instead of waiting to get replacements. For more information please see our Shipping Policy page.

Occasionally you will have an item with a visible defect either in the stain, finish, or milling. Like most building materials suppliers our effective defect rate is under the industry-standard 3%. However, if you are finding that more than 3% of the product you have ordered has defects, please let us know as soon as possible so we can resolve the matter quickly.

MagPanel® MgO Panels 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.

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.

We recommend that you review our handy Return Shipping Guide to see the detailed steps to return your order.

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.

Yes, we may be able to accommodate this, but please note that we may still apply a small shipping and handling fee to your order.  Please reach out to your sales representative for details.
