Demountable wall system having a seamless covered wall

A demountable wall system having seamless wall panels adapted to be mounted between a ceiling and floor structure comprising:

• a) an elongated floor railing adapted to be disposed adjacent to the floor structure;
• b) an elongated ceiling railing adapted to be disposed under and adjacent to the ceiling;
• c) a series of disconnectable fasteners interconnecting the ceiling railing to the ceiling structure in order that the fasteners can be removed and disconnected such that the ceiling railing and the demountable wall system can be moved from one location to another with respect to the ceiling;
• d) a series of spaced apart upright wall studs mounted between the floor and ceiling railings;
• e) a series of wall panels secured between the ceiling and floor railings;
• f) each wall panel including a front face area, a back face, opposed side edges, a pre-applied exterior wall covering disposed over a central portion of the face area of the panel so as to define a pair of uncovered areas on each side thereof;
• g) the wall panels being mounted side edge to side edge within the demountable wall system such that a seam is defined along the interface between the respective side edges and wherein the uncovered areas about the face of the wall panels are disposed on opposite sides of the defined seam;
• and
• h) a wall covering seam filler strip extending vertically over respective defined seams so as to cover the same and extend over to the uncovered areas of the adjacent wall panels so as to cover the same and to form, in combination with the preapplied exterior covering, a continuous and seamless wall covering.

A method of erecting a demountable and movable wall system between ceiling and a floor structures comprising:

• a) disposing a floor railing adjacent to the floor structure;
• b) detachably securing a ceiling railing to the ceiling;
• c) interconnecting a series of spaced apart wall studs between the floor railing and the ceiling railing;
• d) forming a series of wall panels with each wall panel having a front face, back, opposite side edges, and a pre-applied wall covering that is disposed on a central portion of the face of the wall panel, leaving two uncovered areas on each side thereof with each uncovered area lying between one side edge of the wall panel and an edge of the preapplied wall covering;
• e) after forming the wall panels, mounting the wall panels within the demountable wall system such that the wall panels are disposed side edge to side edge and extend generally between the floor railing and the ceiling railing and wherein there is formed a seam that is defined at the interface between the respective wall panels;
• and
• f) after the wall panels have been mounted within the demountable wall system, applying a wall covering seam filler strip over the defined seam extending at the interface of the respective panels and spreading the wall covering seam filler strip outwardly to where it covers the adjacent uncovered areas that exist on the two panels disposed opposite the seam and interface.
