Efficient thermal insulation is an important aspect of any cold-storage facility’s floor structure, helping to maintain the correct internal temperature, as well as saving precious energy.
The reversal of usual flow of heat and moisture inside to outside through a building structure needs to be taken into account in the case of cold storage i.e. the flow of heat and relatively high moisture levels present in the sub-soil and external environment where the temperature is relatively higher, is towards the colder (low moisture content) cold store interior, via diffusion through the cold store floor and enclosure.
