Panels having foam cores covered by metal skins are interlocked along their respective sides by forming bent parts in the metal skins that interlock with one another. A first interconnecting member is generally hook-shaped and projects outwardly. Its counterpart is also generally hook-shaped and extends inwardly. The counterpart slideably receives the first interconnecting member, transiently deforming as the first interconnecting member enters it, and returns to its position of repose when the first interconnecting member is fully received therewithin. The foam cores of abutting panels are also sculpted to interlock with one another. An elongate, channel-shaped stiffener member has a flat base and upstanding side walls, at opposite sides of the base, that are received within the area bounded by the hook-shaped outwardly projecting part of the first interconnecting member. This enables construction of modular panels of up to forty feet in length. An elongate bead of caulking compound is positioned between the first and second interconnecting members, below the surface of the panels, and spreads out into interstitial spaces between the first and second interconnecting members when contiguous panels are interconnected to one another.
