What is Cold Room Insulation?

Cold room insulation is a vital component that prevents energy loss in cold rooms by mitigating temperature differences with the surrounding environment. The selection and correct installation of insulation significantly affect the performance, energy efficiency, and longevity of cold room equipment. Hence, choosing the right insulation material is paramount. The construction of cold rooms incorporates diverse insulation materials, some of which are outlined below.

Types of Cold Room Insulation

Cold room insulation can be achieved through various materials. While rock wool was previously used for thermal insulation, contemporary advancements have introduced polymer materials that are now commonly employed. Here are some frequently used insulation materials:

– Polyurethane (PU)

– Polystyrene or Expanded Polystyrene (EPS)

– Extruded Polystyrene (XPS)

Polystyrene insulations are typically manufactured in block forms with varying densities, ideal for insulating the cold room floor. On the other hand, polyurethane is extensively produced as sandwich panels and finds common use in insulating cold room walls and ceilings.

Comparison of Insulation Thickness

Insulation quality is typically evaluated through the manufacturer-declared heat transfer coefficient. A lower coefficient indicates superior insulation. Below, you’ll find the recommended thicknesses for various insulation materials—polyurethane, expanded polystyrene with graphite, expanded polystyrene, extruded polystyrene, and mineral wool—in a cold room. However, selecting the appropriate insulation type depends on several factors, including cold room temperature, ambient temperature, location, and more. It’s advisable to seek expert advice for determining the suitable type and thickness based on these specific variables.

What happens if the insulation of a cold storage is not properly selected?

Heat infiltration increases, the compressor runs longer, electricity consumption rises, and as a result the service life of refrigeration equipment is reduced.

How is the thickness of cold storage insulation determined?

It depends on factors such as the design temperature of the cold room, outside ambient temperature, relative humidity, and geographic location, and should be specified by a qualified specialist.

What role does insulation play in preventing frost and internal moisture?

Proper insulation prevents moisture from entering the cold space, reducing frost buildup on the evaporator and lowering the need for defrosting.

Why is the higher initial cost of polyurethane insulation justified?

Although polyurethane is more expensive than polystyrene, it significantly reduces energy consumption and extends equipment life, making it more cost-effective in the long run.

What are the common mistakes in installing cold storage insulation?

Typical errors include unsealed panel joints, not using proper sealing tape, incorrect floor construction, and ignoring moisture resistance, all of which compromise cold room performance.
