Abstract
A self supporting panel system used to fabricate ceilings, floors, walls, or roofs. The panel system is assembled from a plurality of panels, each having a core that is sandwiched between opposing plate members. In a preferred embodiment, the core of each panel includes a unifying material to enhance the load bearing capacity of the panel.

A method for forming a roof structure, comprising:
- providing a plurality of interconnected frame members, the frame members forming an opening;
- locating a core having first and second opposing faces within the opening, the core including a plurality of integrally formed honeycomb cells;
- filling at least a portion of each of the honeycomb cells with a unifying foam material;
- attaching a first plate to the first core face;
- attaching a second plate to the second core face;
- locating at least one wedge member adjacent the first or second plate;
- locating a plurality of rafter boards adjacent one or more of the at least one wedge members so that the rafter boards do not directly contact the first or second plate.
