Abstract: A panel for use in constructing a wall, a frame member used for supporting panels of a wall, and a wall structure which utilizes the frame member and the panels characterized by the edge portions of the panels having interlocking shoulders and catches to enable interlocking the panels together in an assembled relationship and the frame members being metal members having integrally formed clips upstanding from a planar surface for engaging the edge and anchoring the panels on the frame members. The panels may have intermediate channel portions which extend parallel to the parallel edge portions and receive tabs which may be provided with catch means that coact with the shoulders in the intermediate channels for anchoring the panels on the frame members intermediate the edge portion.
