Abstract: A demountable wall system that is adapted to be interposed between a floor and ceiling structure and including a series of wall panels that include a continuous and seamless wall covering. More particularly, the demountable wall system includes a floor railing disposed adjacent to the floor structure and a ceiling railing detachably connected to the ceiling structure. Longitudinally spaced between the ceiling and floor railings are a series of upright wall studs. Secured generally between the ceiling and floor railings and connected to the wall studs is a series of wall panels that are disposed edge to edge to form a continuous wall along one or both sides of the demountable wall system. Each wall panel includes a face area and there is applied to the central portion of the face area a wall covering. However, this pre-applied wall covering is not applied to the entire face. Outer areas on each side of the pre-applied wall covering are left uncovered.
