in preparation for the tenth stage in this stage the sheeting material is conveyed under the framing assembly and pressed up and adhesively joined to the framing members in addition fastening equipment such as automated screw guns or steel nail guns mechanically fasten the sheeting material to the framing members from below the panel plane stage 11 transfer of frame with bottom sheeting to a conveyor the framing assembly with bottom sheeting attached transfers to a conveyor system stage 12 installation and pressure testing of pre assembled mechanical and utility systems in this stage the mechanical and utility systems are fed through the holes in the transverse members and along the open edge beam channel from above once connections have been made between systems the assembly is pressure tested for quality control in this stage the framing assembly with attached lower sheeting and installed mechanical and utility systems advances to a vapor control area and the void between members is insulated with expanding foam issued from nozzles mounted above the panel plane the insulation can either be a soy u201c bio based u201d formulation or a traditional foam product nozzles above the panel plane lay a bead or coating of adhesive on top of the exposed members in.
