Abstract: A construction panel for installation on a construction surface and interlocking connection to a another construction panel comprises a moisture barrier base to inhibit migration of moisture from the construction surface. The base has a pair of opposed first connector edges comprising a first pair of releasable mating elements, and a pair of opposed second connector edges comprising a second pair of releasable mating elements. A plurality of projections extend from the underside of the base for support and to permit air circulation and drainage of water between the base and the construction surface. In one embodiment, an upper panel having selected physical characteristics is attached to the base. The positioning of the first and second pairs of mating elements on the first and second pairs of connector edges enables the interconnection of entire or partial construction panels.
