How are coolers insulated? What materials are used for cooler insulation? Is cooler insulation eco-friendly? What is the thermal efficiency of cooler insulation? What is the best cooler for ice retention?
These are some of the common questions you will find when looking into the specifics of insulated coolers and what makes them superior to conventional coolers. So what makes a great cooler? Think about it from a thermodynamics standpoint. Cold is the absence of heat, much like darkness is the absence of light. The goal of a cooler, then, is not so much to keep the “coldness” in but to keep the heat out.
