Abstract: A structural, insulating, insect resistant, dimensionally stable composite wall panel for building construction comprising a regular tetragonal body of polymer foam having two opposing primary wall surfaces bounded on its sides by two parallel side walls and on its ends by two parallel end walls; and at least one light metal gauge hollow stud in the body, each light metal gauge stud extending at least from one end wall to the other end wall and parallel to the side walls of said body, the polymer foam extending into the center of the stud to secure the stud to the body, at least one side wall of each stud forming a portion of the same primary wall surface of said body.
