Foam forms for use in making a concrete wall are disclosed together with a method of making the forms. The forms are stackable to form a cavity that receives the concrete. Each form has two identical panels. The panels are molded separately by first placing a structure, consisting of backing plates that will be along one side of the mold, connecting members that will be along the opposite side of the mold and an apparatus that connects the backing plates to the connecting members, in the mold. The mold is then filled with foam which cures and produces a panel with the backing plates, connecting members and apparatus molded into the panel. The molded panels are then shipped to the job site where the forms are assembled. Each form is assembled as follows: The connecting members on one panel are interconnected, by tieing means, to the connecting members on a second panel to provide a form.
