Tumbler Insulation 101 It’s important to know the different kinds of insulation, so you can explain it clearly to your client. Below, we’ve explained each type of tumbler insulation and ranked them by good, better, best and premium. Good: Air Insulation Air between the inner and outer walls insulates the beverage inside by forcing hot or cold to transfer through a layer of air. This means it takes longer for heat or cold to escape, so your drink stays at the right temperature longer. Better: Foam Insulation Foam between the inner and outer walls slows down the transfer of hot or cold from the inner wall to the outer wall. Foam insulation helps regulate the temperature inside the tumbler. Best: Vacuum Insulation In many containers, heat or cold finds its way out through convection. Tumblers with vacuum insulation have a virtually airless space between the walls to stop the convection process and minimize temperature changes. The hot or cold can only radiate between the walls so drinks stay hotter or colder longer. Premium: Copper Vacuum Insulation A copper lining between the inner and outer walls of a tumbler can lead to even better insulation performance. Copper lining helps distribute the hot or cold air more evenly across the entire inner surface, so your drink is able to retain its temperature for even longer periods of time.
