A composite wall panel is provided. The composite wall panel comprises a first layer of molded structural material and a second layer of molded structural material. An insulating foam layer is disposed between the first and second molded structural layers. The foam layer includes a first major side in contact with the first layer of molded structural material and a second major side in contact with the second layer of molded structural material. The first and second major sides of the insulating foam layer each have at least one groove. Each groove has at least one groove shoulder. At least one connector is configured to anchor the first and second layers of structural material to the insulating foam layer. The first and second layers of molded structural material extend into the grooves and under the groove shoulders to form a mechanical engagement between the insulating foam layer and the first and second layers of molded structural material.
