MagO® — The New Generation Building Material
The MagO® product line is engineered to eliminate the toughest problems faced by architects, engineers, contractors, and builders today while also making construction easier. Addressing both, magnesium-oxide ceramic-cement boards result in lower construction costs during installation and reduced maintenance expenses over the lifespan of the building.
Mago panels provide a superior alternative for healthy, affordable, durable, and energy efficient buildings. MagO board is a technologically advanced building material offering superior performance in every category when compared to traditional wood, gypsum, and cement based products.
Magnesium oxide more commonly called magnesia is a versatile mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction. MagO magnesium-oxide boards are suitable for a wide range of general building uses and for applications that require fire resistance, mold and mildew control, as well as sound control applications and many other benefits.
As an environmentally friendly building material, mago has strength and resistance due to very strong bonds between magnesium and oxygen atoms that form the magnesium oxide molecules (chemical symbol MgO).
Mago boards are used in place of fiber cement and traditional gypsum drywall as wall and ceiling covering material and sheathing, as well as in a number of other construction applications.” (description from wikipedia)
MagO boards are a mineral based green building product cast from homogeneous cement slurry, they cannot delaminate. They will have a positive impact on occupants’ health and safety while extending the life of the building investment.
What Differentiates MagO Board From other Materials?
MagO Board is virtually impervious to:
Water
In addition to the above characteristics, MagO has excellent adhesion values that are perfect for Portland stucco, acrylic stucco, wallpaper, stone, tile, brick, and much more. MagO’s adhesion values also allow it to be endorsed by most major suppliers of finishes including Imasco Minerals, Master Wall, Acrylabs, Mapei, Surecrete, Carpenter Stone, Total Wall, Stucco Flex, and Encap are part of a growing list. Since MagO Board is glass smooth on one side, a level five beautiful and durable finish can be achieved with much less work than typical gypsum board and it can be painted the same day as they are installed. For paint, it is recommended to use a specified primer suitable for alkaline substrates such as Sherwin Williams’ Loxon.
Wherever gypsum and fiber-cement products are used, MagO is a superior alternative. Applications include: interior walls, ceilings, backer board, and underlayment; exterior wall cladding, soffit, siding, and trim. MagO is also widely used in MagO Insulated Panels (MIP) and such Original Equipment Manufacture (OEM) applications as MagO Cladding System, an integral rain-screen commercial grade siding.
MagO board has different characteristics than gypsum. It can be scored and snapped but better results come from cutting with carbide saws and shaping with routers. Attachment can be done using a nail gun, which results in much faster construction time or screws that are able to self countersink. MagO boards have superior strength compared to gypsum for impact, fastener holding, and shear applications. A single #10 screw in a 12 mm board can hold over 200 lbs in shear and 160 lbs in tension. Due to its hardness, Corner and J beads are not required. Joints do not have to be on a stud and it is possible to go from board installation to painting the same day. Moreover, because of its stiffness, thinner boards can be used. Ten millimeter or three eighth inch works well for walls and eight millimeter can be used for ceilings.
