A cold room is a different construction of other industrial buildings as it is meant for conservation (storage) products for a long time maintaining a low temperature.
Depending on the temperature we find two types of cold rooms:
- The positive cold rooms.
- The negative cold rooms.
But according to the construction there are three categories:
1) removable prefabricated cold rooms:
These are isolated local where all surfaces are made of sandwich panels prefabricated in the factory and can be assembled and disassembled repeatedly. Often the panels are equipped with eccentric system of locks operable by key close and clamp the two panels to each other with the addition of a seal between the two

demountable prefabricated cold rooms:
These are rooms where at least one wall is made of prefabricated sandwich panels at the factory then assembled on site permanently without metal frames and locks system.

the walls are built of masonry, insulation is then a dubbing for decreasing the heat transfer. Except that provision requires the establishment of a screen to protect the insulation steam in addition to a system for fixing the latter on the walls.A] The insulation of Cold Rooms:
Isolation is the main element that enters the construction of cold rooms, whatever their nature, since it promotes resistance against heat transfer heat from the hot environment to a cold environment. Thus a good insulator must have the following characteristics:
- Conductivity coefficient (λ) small.
- Low dimensional variation.
- Impermeability to water vapor.
- Low Cost.
- Flammable or with a low reaction to fire.
- Easy to work and carry.
- Not alterable by microorganisms (fungi, insects, pests ...).
