Abstract: The present invention relates to a modular panel construction comprising a plurality of generally rectangular, individual panel sections. The panel sections include side coupling brackets for interconnecting the adjacent side marginal edges of adjacent panel sections. A tongue and groove arrangement is provided for coupling the lower marginal edge of an upper section with the upper marginal edge of an adjacent lower section. The plurality of sections cooperate to form a wall panel having an outer periphery defined by the arrangement of the panel sections. A pair of spaced apart hinge brackets are utilized to pivotally connect one wall panel to a second wall panel.
