Efficient thermal insulation is an important aspect in case of the floor structure of cold-storage warehouses in order to ensure maintenance of the desired permanent inside temperature, beyond saving precious energy.
The reversed flow of moisture versus the generally moderated spaces should be taken into consideration. Such flow should be construed as the flow of relatively high moisture content present in the outside medium of higher temperature towards the colder (dry) interior space of low moisture content, via diffusion through the space limiting structures.
