Abstract:
A structural building panel, comprising:(a) a first facing sheet having opposing first and second side edges and opposing top and bottom edges; (b) a second facing sheet having a size and configuration corresponding to that of the first facing sheet, said second facing sheet having opposing first and second side edges and opposing top and bottom edges and being disposed in opposing, spaced-apart relationship to said first facing sheet; (c) a core of cured foam resin disposed between and adhered to said first and second facing sheets to define an insulation barrier between the first and second facing sheets; (d) a first elongate recess formed in and defined by exposed surfaces of the core of cured foam resin adjacent to and co-extensive with the first side edge of said first facing sheet for receiving a spline of a first abutting building panel; (e) a second elongate recess formed in and defined by exposed surfaces of the core of cured foam resin adjacent to and co-extensive with the second side edge of said second facing sheet for receiving a spline of a second abutting building panel; (f) a first rigid structural spline member positioned adjacent to and co-extensive with the first side edge of said second facing sheet for being matingly fitted into the complementary recess defined by exposed surfaces of the core of cured foam resin of the first abutting building panel, said first rigid structural spline member providing a form into which foam resin is molded to provide re-enforced support to the foam underlying the spline member; (g) a second rigid structural spline member positioned adjacent to and co-extensive with the second side edge of said first facing sheet for being matingly fitted into the complementary recess defined by exposed surfaces of a core of cured foam resin of the second abutting building panel, said first rigid structural spline member providing a form into which foam resin is molded to provide re-enforced support to the foam underlying the spline member; (h) said first structural spline member and second structural spline member each being spaced-apart from at least one of the first and second facing sheets for reducing thermal transfer between the first and second spacing sheets.
