![]() ![]() Again you can get a good sized roll of Reflectix for a good price here at Amazon. To do this use a roll of reflectix/bubble foil that you can pick up for your local hardware store. Instead of lining the inside of your cooler with extra insulation or bubble foil you can create an external cooler cover that can slide on and off your cooler and provide extra protection from the sun's heat. How To Insulate The Lid of Your Cooler With Spray FoamĪnother way to increase the insulation of your cooler is to make a cooler cover. A lot of people use “Great Stuff” but from the research I've done that doesn't seem to work as well. I recommend this Loctite Big Gaps spray foam which is designed to fill large areas and has a high densisty insulating structure. Buying the wrong foam can decrease the performance of your cooler. You want to make sure your get a closed-cell polyurethane insulating foam as these insulate the best. Much expanding foam is designed to fill gaps and create seals not to insulate. IMPORTANT! Not all foams are created equal. The using the wrong foam might not insulate your cooler but provide dense material for heat to easily move through, getting into your cooler and melting your ice. However, don't incorrectly it can actually decrease the ice retention of your cooler. So in some cases your cooler could hold ice up to twice as long. When done correctly it can increase the ice retention capabilities of your cooler by 50-100%. So insulating the lid of your cooler is a great way to add extra insulation and keep ice longer. It may surprise you but the lids of cheaper coolers are generally completely empty and don't contain any insulation at all, only air! Optional: Use a food safe vinyl or plastic to line the inside of the cooler so it becomes leak proof and food safe.Optional: Paint interior with flex seal to seal it up.Fill in the gaps where the pieces connect with duct tape, silicone or hot glue.Place inside the cooler sticking it to the walls and floor using an all purpose glue if you wish to connect the pieces together as well as to each other.Cut out the floor and side pieces from your foam board.Measure the inside dimensions of your cooler making sure to measure and cut the bottom piece first. ![]() Here are the steps of add extra insulation to the walls of your cooler: ![]() Polyurethane foam is the same foam they use in a Yeti cooler and is the most effective insulator. Polyiso is also good and often comes with a reflective layer which adds more insulation. XPS is more effective and can be purchased from any local hardware store as it's often used in building insulation. The first two videos were successful and the hacks helped their regular 1-day coolers hold ice for around 2.5 days in the summer heat. There is no point spending time and money on adding insulation and hacks to your cooler if it isn't going to hold ice any longer.īelow you can see 2 different videos of people using cooler hacks to try and improve the performance of their coolers. Do Cooler Hacks Actually Work?įirst I want to look at whether or not these cooler hacks actually work. To insulate a cooler so it hold ice longer add insulation to the walls using polystyrene board, fill the lid with insulation and add a reflectix cover and you'll get superior ice retention performance. So how do you insulate a cooler and what are the most effective methods of doing it? Rather than going out there and spending hundreds of dollar on an expensive cooler like Yeti there are simple, easy and affordable ways to insulate a cooler so it holds ice for longer.īy using these tips you can turn a cheap cooler that struggles to hold ice for a day into a cooler that can hold ice for multiple days at a time and even rival the performance of some of the high-end coolers. ![]()
