1. An apparatus for manufacturing unitary insulated wall panels, the apparatus comprising: a) bending means configured to form an individual panel from a single sheet of metal, the panel having: an enclosed and open-faced cavity comprising four sidewalls and a bottom wall for receiving and containing insulation, the four sidewalls defining four sides around a perimeter of the open-faced cavity of the panel, andpanel attachment means, formed by the bending means to comprise at least one lateral flange extending from and integral to at least one of the sidewalls, for affixing the panel to a wall, andb) insulation application means for applying expandable foam insulation to the open-faced cavity, the application means having an applicator head configured to dispense the foam insulation at a pre-determined rate and pressure, and in a pre-determined pattern, and configured to reduce usage of an excess volume of the foam insulation and to provide a predetermined amount of air within the foam insulation, andpress means for receiving and pressing the panel while the foam cures, the press means being configured to prevent overflow of foam outside of the panel and to provide a flat finish to an insulation surface. 2. The apparatus of claim 1, wherein the panel attachment means correspond to wall attachment means on a wall, to an adjacent panel or both. 3. The apparatus of claim 1, wherein the foam insulation is a polyurethane foam insulation. 4. The apparatus of claim 3, wherein the polyurethane foam insulation is an open-cell spray foam insulation. 5. The apparatus of claim 1, wherein the applicator head comprises a nozzle. 6. The apparatus of claim 5, wherein the apparatus further comprises press means for receiving and pressing the panel while the foam cures. 7. An apparatus for manufacturing unitary insulated wall panels, the apparatus comprising: a) bending means configured to form an individual panel from a single sheet of metal, the panel having: an enclosed and open-faced cavity comprising four sidewalls and a bottom wall for receiving and containing insulation, the four sidewalls defining four sides around a perimeter of the open-faced cavity of the panel, andpanel attachment means, formed by the bending means to comprise at least one lateral flange extending from and integral to at least one of the sidewalls, for affixing the panel to a wall, andb) insulation application means for applying expandable foam insulation to the open-faced cavity, the application means having an applicator head configured to dispense the foam insulation at a pre-determined rate and pressure, and in a pre-determined pattern, and configured to reduce usage of an excess volume of the foam insulation and to provide a predetermined amount of air within the foam insulation, andan oven for heating the panel before the insulation is applied. 8. The apparatus of claim 7, wherein the oven heats the panel to a temperature of approximately 80-100° F. 9. The apparatus of claim 8, wherein the panel is heated to a temperature of 95° F. 10. The apparatus of claim 1, wherein the panel is manufactured of steel or aluminum. 11. The apparatus of claim 1, wherein the panel is an exterior wall panel or a curtain wall back panel. 12. The apparatus of claim 1, wherein some or all of the apparatus is automated. 13. The apparatus of claim 1, wherein some or all of the apparatus is manually operated.
