The invention involves an insulation device comprising of a pad defined by a length and a width suitable for fitting snuggly within a cavity of a cooler. In exemplary embodiments, the pad comprises a closed-cell polyvinyl chloride nitrile butadiene rubber foam, also known as PVC/NBR, the pad defined by dimensions including a certain thickness such that the pad may be compressed against the interior walls of the cooler cavity without collapsing or folding over. The edges of the pad may be pressed against the interior walls of the cooler cavity to form a compression seal throughout the perimetrical edge of the pad against the interior walls of the cooler cavity; the compression-sealed edge prolongs a period during which low temperatures may be maintained. The pad is preferably water resistant, lightweight, washable, sufficiently flexible and can be easily trimmed or cut to a desired size.

1. A cooler chest configured for improved insulation of perishables and cooling medium, comprising: a cover;an interior cavity formed by interior walls, the interior cavity having an interior depth, length and width; anda flexible insulating pad laying substantially planar along an entire surface of the interior cavity of the cooler chest, comprising: a rectangular prism having a planar top surface covering the entire surface of the interior cavity, a planar bottom surface, a thickness sufficient to allow compression without bowing the flexible insulating pad, and a length and a width slightly greater than a length and a width of the interior cavity of the cooler chest, anda planar edge along a perimeter of the rectangular prism that is pressed against the interior walls of the cooler chest so that the flexible insulating pad does not bow along the entire surface of the interior cavity and the planar edge conforms to the interior walls forming a compression seal throughout an entire perimetrical boundary between the flexible insulating pad and the interior walls of the cooler chest, the compression seal comprising: a first bulge along a top surface of the planar edge of the flexible insulating pad, anda second bulge along a bottom surface of the planar edge of the flexible insulating pad. 2. The cooler chest of claim 1, wherein the flexible insulating pad is a sheet of closed cell polyvinyl chloride nitrile butadiene rubber (PVC/NBR) foam. 3. The cooler chest of claim 1, wherein the flexible insulating pad separates the interior cavity of the cooler chest into a first cavity and a second cavity, the perishables and cooling medium occupying the first cavity and a space between the top surface of the flexible insulating pad and a bottom surface of the cover forming the second cavity. 4. The cooler chest of claim 1, wherein the flexible insulating pad comprises a thickness of 0.75 inches. 5. The cooler chest of claim 1, wherein the dimensions of the flexible insulating pad comprises include: a length between 35 to 45 inches; anda width between 15 and 20 inches. 6. The cooler chest of claim 1, wherein the dimensions of the flexible insulating pad comprises include: a length between 20 to 30 inches; anda width between 10 and 15 inches. 7. The cooler chest of claim 1, wherein the cooling medium comprises one or more selected from the group of: crushed ice, cubed ice and a block of ice. 8. The cooler chest of claim 1, wherein the cooling medium comprises an ice pack. 9. The cooler chest of claim 1, wherein the cooling medium comprises a refrigerant gel. 10. The cooler chest of claim 1, wherein the perishables comprise one or more selected from the group of: food items; drinking products; and medical products. 11. A method of insulating a portion of a cooler chest packed with perishables and cooling medium, comprising: cutting a single sheet of a closed cell polyvinyl chloride nitrile butadiene rubber (PVC/NBR) foam to form a pad, the pad comprising a planar top surface, a planar bottom surface and a thickness sufficient to allow compression without bowing the pad when pressed against interior walls of the cooler chest, the pad defined by a length and a width slightly greater than a length and a width of an interior cavity formed by the interior walls of the cooler chest;placing the pad over the interior cavity and below a cover of the cooler chest to conceal the perishables and cooling medium; andsealing the interior cavity of the cooler chest with a compression seal throughout an entire perimetrical boundary between the pad and the interior walls of the cooler chest, including: pressing a planar edge along a perimeter of the pad against the interior walls of the cooler chest so that the planar edge conforms to the interior walls of the cooler chest, wherein the pad remains substantially planar along an entire surface of the interior cavity of the cooler chest and the pad does not bow, andforming a bulge on a top surface and a bottom surface of the planar edge of the pad pressed against the interior walls. 12. The method of claim 11, wherein placing the pad over the interior cavity and below a cover of the cooler chest comprises: separating the interior cavity of the cooler chest into a first cavity and a second cavity with the pad, wherein the perishables and cooling medium occupy the first cavity and a space between the surface of the pad and a bottom surface of the cover forms the second cavity. 13. The method of claim 11, wherein cutting the single sheet of PVC/NBR foam to form a pad comprises cutting the single sheet to include a thickness of 0.75 inches. 14. The method of claim 11, wherein cutting the single sheet of PVC/NBR foam to form a pad comprises cutting the single sheet to include: a length between 35 to 45 inches; anda width between 15 and 20 inches. 15. The method of claim 11, wherein cutting the single sheet of PVC/NBR foam to form a pad comprises cutting the single sheet to include: a length between 20 to 30 inches; anda width between 10 and 15 inches. 16. A cooler chest configured for improved insulation of perishables and cooling medium, comprising: an interior cavity formed by interior walls, the interior cavity having an interior depth, length and width; anda flexible insulating pad laying substantially planar along a surface of the interior cavity of the cooler chest, comprising: a rectangular closed cell polyvinyl chloride nitrile butadiene rubber (PVC/NBR) foam having: planar top surface covering the entire surface of the interior cavity, a planar bottom surface, a thickness sufficient to allow compression without bowing the flexible insulating pad, and a length and a width slightly greater than a length and a width of the interior cavity of the cooler chest, anda planar edge along a perimeter of the flexible insulating pad that is pressed against the interior walls of the cooler chest so that the flexible insulating pad does not bow along the entire surface of the interior cavity and the edge conforms to the interior walls forming a compression seal throughout an entire perimetrical boundary between the flexible insulating pad and the interior walls of the cooler chest, the compression seal comprising: a first bulge along a top surface of the planar edge of the flexible insulating pad, anda second bulge along a bottom surface of the planar edge of the flexible insulating pad, wherein the dimensions of the flexible insulating pad comprises include: a thickness of 0.75 inches; a length between 20 to 45 inches; and a width between 10 and 20 inches. 17. The cooler chest of claim 16, wherein the cooling medium comprises one or more selected from the group of: crushed ice, cubed ice and a block of ice. 18. The cooler chest of claim 16, wherein the cooling medium comprises an ice pack. 19. The cooler chest of claim 16, wherein the cooling medium comprises a refrigerant gel. 20. The cooler chest of claim 16, wherein the perishables comprise one or more selected from the group of: food items; drinking products; and medical products.
