Cutting DragonBoard Structural Panels

How DragonBoard is Made

Dragonboard is made by combining MgO (calcined crushed magnesite) with what is commonly known as Epsom salts (MgSO4), proprietary fibers, and a water slurry then laid out in molds with multiple layers of fiberglass mesh. Boards are air dried for 3 days before being cut to precise dimensions then conveyed to quality control for inspection.

While seemingly straightforward, it is as much artform as science to maintain consistently excellent quality boards. We like to think of the process as similar to a distiller of fine whiskey, and we are equally proud of our production. Our boards contain none of the hazardous materials associated with Portland cement, Plywoods, OSB and other alternatives. Indeed, you could literally eat DragonBoard… though we do not vouch for any of its’ culinary qualities.

Sustainability and Green Building

Unlike Portland Cement based boards and pours, DragonBoard contains no hazardous components such as crystalline silica and hexavalent chromium, and the dust is not an irritant. In contrast cases of extreme exposure to Portland-based products, the results can lead to adverse health outcomes and worse.

Unlike Portland cement-based boards, there are no environmental concerns from extremely high energy consumption in manufacturing cement, and the related air pollution, such as the release of dioxin, NOx, SO2, and particulates. In contrast, the production of Portland cement contributes to about 10 % of world carbon dioxide emission and is the most energy-intensive industry in the world.

Unlike Plywoods and OSBs, DragonBoard does not contain any formaldehyde or adhesives, nor mold or termite abatement chemicals. DragonBoard is also naturally mold and termite resistant.

DragonBoard can be recycled for agriculture uses and is landfill friendly.
