ABSTRACT:
A generally planar structural panel includes first and second opposed outer facings with an insulating foam core disposed therebetween. Prior to attachment to the two outer facings, which may be of virtually any of the more common building materials, cuts are made in the foam core extending the length and width thereof. These cuts are in the form of linear elongated slots or channels and are made in the foam so as to form a plurality of thin elongated foam strips within each channel. The cuts may be made using a hot wire in a conventional manner during manufacture without removing the thus formed foam strips. The outer facings are then attached to opposed surfaces of the foam core. Each group of adjacent foam strips may be accessed by cutting a hole in an outer facing of the panel and into the foam to the depth of the strips. The thin foam strips may then be pulled out of the foam core through the thus cut hole to form an elongated, linear slot in the panel extending the length or width thereof which may be used as an electrical wiring chase. In another embodiment, the thin foam strips are removed during manufacture and the thus formed wiring chase is filled with loose filled foam with the ends of the chase sealed with tape. In the field at a job site, the tape may be removed and the loose fill foam vacuumed from the foam core in forming a wiring chase.
