The method includes introducing at least a portion of an unfilled stud wall between a backplate and a dam, with the sheathing against the backplate; moving the dam against the bottom portion of the open side of the stud wall; introducing foam between the backplate and the dam to fill the stud wall therebetween; moving the dam; introducing additional foam to fill a further portion of the stud wall; repeating the two preceding steps on to completion of filling; moving the dam away from the stud wall; and advancing the filled portion of the stud wall from between the backplate and dam.
