1. A building panel comprising:

  • a first sheet intended to provide an inner building surface, the first sheet being corrugated to define a plurality of generally parallel channels that extend along the length of the panel;

    a second sheet arranged generally parallel to the first sheet and intended to provide an outer building surface;

    the longer dimension of each of the first and second sheets defining the length of the panel, and the shorter dimension of each of the first and second sheets defining the width of the panel;

    an insulating foam core sandwiched between the first and second sheets extending substantially the entire length and width of the panel, such that the foam core occupies the entirety of the space defined by the first sheet and the second sheet, including the space defined by the second sheet and the corrugations of the first sheet;

    the panel also having edges defined by the surfaces of the foam core between the sheets running the length of the panel;

    the first and second sheets being in spaced apart relationship for substantially the entire length and width of the panel apart from along at least one edge of the panel; and

    a discreet load bearing rib separate from the first and second sheets, the rib extending along one edge of the panel and being connected to the first sheet and to the second sheet,wherein the channels each have side walls that define intermediate ledges extending inwardly at a depth to accommodate within the respective channel an electrical box of a first size and also have a bottom at a depth to accommodate within the respective channel an electrical box of a second size, said first size being different from said second size.
