Cold storage facilities are warehouses designed to house and protect refrigerated and frozen goods. Items requiring cold storage range from food, cosmetics, plants, medicine and many other products. While the exterior appearance of these facilities may look like any other warehouse, their interiors are actually very complex. Insulation and refrigeration are two of the main focus points when it comes to the design of a cold storage facility. These choices are primarily driven by the product being stored, size and height of the building and operating costs of the facility.
