An inflatable or gas-filled insulation panel comprises an envelope having two outer sheets sealed together along edges of the sheets and at least one of the sheets has an outer reflective surface. The envelope encases a plurality of internal films that include a polymeric film having a plurality of reflective stripes disposed thereon and spaced apart on the films. Seals are formed along the gaps or areas between the reflective stripes on the films by application of heat and pressure, which causes the films to seal to each other and the outer sheets at spaced apart intervals. A channel is formed between the outer edges of the films and the outer sheets, and a valve, disposed at an end of the panel, is in fluid communication with the channel for the injection of a fluid, such as an inert gas or air, to inflate panel.

1. A system for assembling an inflatable insulation panel having an envelope with an outer reflective surface and a plurality of internal films, each film being of a polymeric material and having a plurality of reflective surfaces thereon and spaced apart, comprising: at least one heating platen for supporting a first and second sheet of laminated material, at least one of which includes the outer reflective surface and an inner polymeric surface, and the internal films positioned between the first and second sheet, said heating platen for providing heat to seal the films to one another and to the first and second sheets;an insulating layer positioned on the platen disposed between the platen and the first and second sheets of laminated material; and,a die press for applying pressure against the two sheets and films while the platen provides a source of heat wherein the die includes a plurality of ribs having a plurality of internal ribs aligned with gaps in the films between the spaced apart reflective surfaces and two external ribs positioned outside the internal ribs along the die press, parallel to the internal films, disposed at corresponding ends thereof for forming lateral seals extending the width of the panel at lateral ends of the panel. 2. The system of claim 1, wherein the die applies a pressure of about 25 lb/in2 to about 40 lb/in2 and the platen is heated to a temperature of about 250° F., both for a dwell time of about 4.75 seconds. 3. The system of claim 1, wherein the heating platen includes a plurality of quadrants the temperature of each quadrant can be controlled independent of one another. 4. The system of claim 1, wherein a width of the first and the second sheet is greater than a width of the internal films based on lateral edges of the first and second sheets being positioned outside lateral edges of the internal films. 5. The system of claim 4, wherein the internal ribs form lateral seals along the insulation panel between the lateral edges of the internal films and that the external ribs form lateral seals along the insulation panel between the lateral edge of the internal film and the lateral edge of the first or second sheet. 6. The system of claim 1, wherein the insulating layer comprises: a first silicone rubber layer disposed between the platen and the first and second sheets of laminated material; anda second silicone rubber layer disposed between the first silicone rubber layer and the first and second sheets. 7. The system of claim 6, wherein the first silicone rubber layer is a high temperature silicone sponge rubber layer with a thickness in a range between ⅛″ and ¼″, and wherein the second silicone rubber layer is an ethylene propylene diene monomer rubber with a thickness of ¼″. 8. The system of claim 7, wherein a diameter measurement of the ethylene propylene diene monomer rubber of the second silicone rubber layer is 50 A. 9. A platen assembly for assembling an inflatable insulation panel having an envelope with an outer reflective surface and a plurality of internal films, each film being of a polymeric material and having a plurality of reflective surfaces thereon and spaced apart, said platen assembly comprising: at least one heating platen for supporting a first and second sheet of laminated material, at least one of which includes the outer reflective surface and an inner polymeric surface, and the internal films positioned between the first and second sheet, said heating platen for providing heat to seal the films to one another and to the first and second sheets;a first insulating layer positioned on the platen disposed between the platen and the first or second sheets wherein the first insulating layer comprises a first silicone rubber layer disposed between the platen and the first or second sheets and a second silicone rubber layer disposed between the first silicone rubber layer and the first or second sheets;a second insulating layer positioned between the heating platen and a support table below the heating platen; anda die press for applying pressure against the two sheets and films while the platen provides a source of heat wherein the die includes a plurality of ribs having a plurality of internal ribs aligned with gaps in the films between the spaced apart reflective surfaces and two external ribs positioned outside the internal ribs along the die press, parallel to the internal films, disposed at corresponding ends thereof for forming lateral seals extending the width of the panel at lateral ends of the panel. 10. The system of claim 9, wherein the die applies a pressure of about 25 lb/in2 to about 40 lb/in2 and the platen is heated to a temperature of about 250° F., both for a dwell time of about 4.75 seconds. 11. The system of claim 9, wherein the heating platen includes a plurality of quadrants the temperature of each quadrant can be controlled independent of one another. 12. The system of claim 9, wherein a width of the first and the second sheet is greater than a width of the internal films based on lateral edges of the first and second sheets being positioned outside lateral edges of the internal films. 13. The system of claim 12, wherein the internal ribs form lateral seals along the insulation panel between the lateral edges of the internal films and that the external ribs form lateral seals along the insulation panel between the lateral edge of the internal film and the lateral edge of the first or second sheet. 14. The system of claim 9, wherein the heating platen comprises a flexible heat tube configured to provide the source of heat at a controlled temperature such that the application of pressure from the die press is applied at a uniform temperature during repetitive impressions. 15. The system of claim 9, wherein the heating platen comprises a pair of heating tubes on an underside of the platen, said heating tubes connected to a respective thermocouple. 16. The system of claim 9, wherein the first silicone rubber layer is a high temperature silicone sponge rubber layer with a thickness in a range between ⅛″ and ¼″, and wherein the second silicone rubber layer is an ethylene propylene lene monomer rubber with a. thickness of ¼″. 17. The system of claim 16, wherein a durometer measurement of the ethylene propylene diene monomer rubber of the second silicone rubber layer is 50 A.
