METHOD AND APPARATUS FOR PRODUCING PREFABRICATED FOAM-INSULATED WALLS |
摘要 |
A method for producing foam-filled stud walls includes introducing at least a portion of an unfilled stud wall between a backplate, with the sheathing against the backplate, and a dam having a compressible membrane draped over one face thereof and a removable sheet draped over the compressible membrane for presenting to the studs; 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 while unrolling the removable sheet and compressible membrane; 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.
