Identify a major disadvantage of using shipping containers for storage.

Limited insulation compared to buildings is indeed a significant disadvantage when using shipping containers for storage. While shipping containers are robust and durable structures suitable for transporting goods, they are typically made of steel, which provides minimal insulation against temperature fluctuations. This can lead to extreme cold or heat inside the container, depending on the external climate. Therefore, items sensitive to temperature and humidity may not be adequately protected without additional insulation measures.

In contrast, purpose-built storage facilities are designed with climate control options, making them more suitable for sensitive items. Consequently, while shipping containers can be efficient for many storage needs, the lack of thermal regulation is a crucial factor to consider. This is particularly important for long-term storage or for items that require specific environmental conditions to preserve their integrity.
