X-Board Hard foam board

codex X-Board is a versatile, fabric-reinforced hard foam board for renovation and refurbishment projects. It is used to create stud walls, installation panels, bath panels, washstands and shelves, as well flat surfaces, e.g. on partially tiled walls. It is also used on load-bearing substrates to support tile and natural stone using the thin-bed method, on textured plasters, smoothing filler and other materials for further surface designs.
