ABSTRACT:
Foamed-in-place metal skin covered insulating panels for the walls of walk-in coolers, freezers and refrigerated warehouses having a fastening bar assembly encapsulated therein. The fastening bar assembly possesses opposite end male and female fastening means for positive and rigid coupling with like threaded means of adjacent wall panels. The male fastening means includes a lag screw and a unique retaining means for the screw which positions it for use while protecting it from contact with the foamed insulation during fabrication of the panel with the fastening bar assembly in place between jig fixtures. The less efficient, weaker and more costly cam locking means of the prior art is eliminated.
