Note - we DO NOT RECOMMEND USING FIBERGLASS BATT FOR INSULATION!
However, if you are stuck with fiberglass batt for some reason, these plans are a great example of how to use it in a cooler. University of Kentucky did a great job drawing up and breaking down the detailed instructions for this cooler design. For anyone that is going to use these instructions, we recommend using at least another 3/4 inches of rigid foam insulation for a total of at least 1-1/2 inches. This can be added to the outside or inside of the cooler. Whichever way you go, make sure that you seal the seams completely to stop the moisture from getting into that fiberglass. If you’re using this plan, we strongly recommend adding a continuous sheet of polyethylene (carpenters plastic from Home Depot) installed as a vapor barrier between the fiberglass insulation and outside air.
