The Multiboard eXBound 17mm – 3D is a magnesium-oxide (MgO) high performance external boundary wall cladding system allowing 3-dimensional architectural designs (or signage) to be routed into the top surface of the material. The location of the fibreglass mesh in the board is drawn towards the centre, preventing its exposure at the surface while still providing a high-impact resistant, external cladding system for commercial (and residential) applications.
