ABSTRACT OF THE DISCLOSURE The invention discloses a method and apparatus For producing foam-filled stud walls. The apparatus has a main frame, including a substantially vertical backplate against which the sheathing bears, a carrier unit moveable vertically on the main frame, and a dam carried on the carrier unit parallel to the backplate, moveable towards and away from the backplate. Hydraulic actuators are located between the carrier unit and main frame, and between the dam and the carrier unit, to hold the dam against the stud wall when the stud wall is positioned with its sheathing against the backplate, and to move the carrier unit and thus the dam vertically while it is so held against the stud wall. The method includes introducing at least a portion of an unfilled stud wall between a substantially vertical backplate and a substantially vertical 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 upwardly; introducing additional foam to fill a higher 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.
