4 Ways Reflective Material Improves Cooler Performance

Focus on reflective material, not bulky insulation Adding foam or fiberglass inside a cooler eats up space for drinks. Reflecting heat away before it enters is more effective than slowing it down after it gets inside.

Line the lid with reflective bubble wrap Cut a piece of Reflectix or an emergency blanket to fit the underside of the lid and tape it on. This blocks radiant heat from the sun or hot air.

Fix the lid seal with weatherstripping Most heat loss happens at the lid gap, not through the walls. A strip of foam weatherstripping does more than extra insulation ever will.

Wrap the outside if the cooler sits in direct sun A shiny exterior reflects heat away, keeping the inside colder longer. This works best if you don’t care about looks.
