The non-combustible Multiboard eXCom is a commercial grade, wall cladding material made from magnesium-oxide (MgO) with a high-impact resistance - three times that of CFC. The use of a light-gauge, steel sub system provides a robust, expressed-edge cladding for external commercial and industrial applications. The eXCom is also available in a greater material thickness to allow for the 3-dimensional routing of architectural designs through the top surface of the material.
