What role do insulation materials play in refrigerated containers?

Insulation materials are crucial in refrigerated containers primarily because they keep the internal temperature stable. These materials create a barrier that minimizes heat transfer between the inside and outside of the container, ensuring that the desired temperature for the storage of perishable goods is maintained. This stability is essential for preserving the quality and safety of items such as food, pharmaceuticals, and other temperature-sensitive products during transport. Proper insulation prevents external temperature changes from adversely affecting the internal environment, effectively facilitating the refrigeration process and ensuring consistent temperatures are achieved.

While weight reduction, aesthetics, and airflow are important factors in container design, they do not address the primary function of insulation in maintaining temperature control and efficiency in refrigerated containers.
