Abstract: A partition panel system, including at least two from each other spaced longitudinally extending supporting sections (1, 1', 1"), having a first end portion arranged with a supporting member (2, 2', 2"), intended to take up contact with a floor surface and to maintain the supporting sections (1, 1', 1") in a substantially vertical direction of extension. Each other adjacently located supporting sections (1, 1', 1") are arranged internally connected by means of at least one frameshaped member, formed by an upper and a lower attachment member and two side members, said frameshaped member being arranged to support one or a number of plate-shaped members and/or to be surrounded by a layer, thus forming a wall surface unit (3, 3', 3").
