Interlocking Cladding Panel and Methods of Use

A cladding panel for siding construction extends preferably vertically on a structure. The panel has an outer layer and an insulting layer. The panel may have an interlocking groove structure on one longitudinal edge and a cooperating tongue structure on an opposite longitudinal edge. The interlocking groove portion and interlocking tongue portion may have cooperating geometry such that like panels may be assembled together by engaging the tongue portion of one panel with the interlocking groove portion of another panel. The panels when assembled may be generally flush to one another with generally flat faces. The insulating layers of assembled panels may have cooperating geometry to enable the panels to lie flat against a structure with only the insulating layers contacting the structure.
