We Environmentally Friendly Building Material for Building Healthier Homes
MgO 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.
MgO gains its strength and resistance from very strong bonds between MgO nesium and oxygen atoms that form MgO nesium oxide crystals (with the chemical formula MgO). MgO is a mineral based green building material. MgO 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.
What is MgO Boards ?
The Great Wall of China and the Roman Empire represent the first uses of magnesia mixed into mortar. By the 20th-century, the use of magnesia declined as builders turned to cheaper options such as Portland cement and other such materials.

Over the past two decades, however, magnesia has returned as a component found in sustainably produced magnesium oxide boards. Several states encourage and approve of builders using magnesium boards because they combine strength and versatility with sustainability and recyclability. High Strength non-Magnesium oxide boards offer replacements for gypsum-based panels, drywall, and other construction boards and panels. They are environmentally benign and boast a host of characteristics beneficial to the safety and health of homeowners and contractors.
Still, not all that many consumers have heard of magnesium board or understand its outstanding features and environmental attributes. It’s a bit of a mystery, and only a small number of websites have much information about magnesium oxide boards.
How Are MgO Boards Produced?
Most magnesium carbonite comes from China and Europe. The process combines magnesium and oxygen with pressure and heat to create magnesium oxide (MgO). The MgO has the characteristics of stone after heating. After being ground into powder, it gets mixed with water, chloride, and sulfate (or Epsom salts) and wood dust (cellulose), perlite, and a handful of other materials.
Install the boards horizontally (crosswise to the profiles) in staggered joints, with the rough surfaces turned outwards, then screw them to the metal framework with special highly corrosion resistant MGO Screws (Ruspert type treatment with salt spray resistance exceeding 1.000 hours) positioned at a maximum centre distance of 200 mm. Leave a space of 3-4 mm between the board edges, filling the space when the first coat of filling is applied.

The joints between the boards must be filled with the outdoor filler, MGO Filler Dry, which should also be used to finish the surface. Apply one 2-3 mm coating of filler interposing the alkali-resistant reinforcement tape; allow filler to dry then smooth off and finish.
Finish the surface with the same product MGO Filler Dry used to fill the joints, laying a coat of about 3 mm; bury the alkali-resistant glass fibre mat into the finishing coat, overlapping the edges by at least 10 cm. Wait for 24 hours, then apply the second finishing coat if necessary. Before applying any other finishing material, allow the finishing filler to dry and harden for at least 24 hours.
INSTALLING THE FINISHING PROFILES
Fix the PVC finishing profiles (edge beams, drips, expansion joint covers, cornices etc.) burying them into the mat on the finishing deck and overlapping the same over the edges of the alkali-resistant glass fibre mat. In particular cases, the profiles may be fixed to the metal sub-structure with the same screws used to fix the boards, or may be fixed to the boards with metal clips.
INSTALLING THE EXPANSION JOINTS
Expansion joints should be installed at every 6 m; joints should also be installed in the following cases:
- at the expansion joints of the building.
- at the floor division of the building.
- at points of variations of the materials of the structure or facing of the building.
The metal support framework should in any case be interrupted at the expansion joints.
