Our “reflect & insulate” design works by reducing radiant heat transfer and slowing conductive heat simultaneously. This synergistic system consists of a reflective barrier and an insulation layer. The reflective barrier repels heat radiation while the insulated core slows down heat transfer from conduction and convection. Radiant barriers are primarily aluminum. However, the insulation layer varies greatly depending on use. Insulated covers can be manufactured with a variety of materials to maximize temperature stability. Cold Chain performance depends on a number of elements e.g. product density and transit time. These materials work together to provide a protective barrier far superior to either element on its own, maintaining a more stable environment without dramatic temperature spikes. According to temperature control requirement and transportation distance, appropriate coolants can be added to further enhance performance. Learn more about Heat Transfer here.
