Abstract

A generally flat structural panel includes a center foam core and opposed outer facings, or sheets, with a metal insert disposed about and attached to the edges of the core and at least one of the outer facings. The metal edge insert provides high strength for the insulated foam panel, eliminates the need for structural members such as studs which act as thermal conductors, and facilitates coupling between adjacent panels, ceilings and floors using various connection arrangements. The structural insulated panels also form the basis of a modular construction system that allows for the use of standard size inside and outside panels of the same size which form a grid in which the outside panels always enclose an area that is a multiple of the module. In one embodiment, a lateral surface of the foam core is provided with a linear array of recesses, or grooves, and a facing is attached to that surface in the field to permit electrical wire routing in the recesses, as required, at the construction site. In another embodiment, metal strips attached to the surface of the core and adapted for secure attachment to a facing such as of drywall provide a space between the foam core and drywall sheet for wire routing.
