Abstract: A modular wall panel to extend between a floor and ceiling has top and bottom horizontal main runners between two vertical beams, each beam having a foot which rests on the floor, the foot being adjustable to adjust the panel height. A first pair of opposing spaced panels extend between the two vertical beams and have lower edges that rest on the bottom main runner and a lower mid-height runner is mounted on the upper edges of the first panel pair to support a horizontal I-beam extending between the vertical beams. An upper mid-height runner is supported on the upper edge of the I-beam and there are a second pair of spaced opposing panels having their lower edges mounted on the upper mid-height runner supported on the I-beam and their upper edges are held by the main runner. A cover member is provided to cover each face of the I-beam.
