How to choose the thickness of the refrigeration panel for a cold storage room?

Date: 13 May 2023

It can be said that in order to maintain an adequate temperature and reduce energy consumption in cold rooms, it is important to choose the correct thickness of refrigeration panels, as these rooms tend to consume large amounts of energy.

Prefabricated refrigeration panels are the most common method used to build cold rooms. Compared to traditional insulation methods, they have several advantages, such as quick assembly, easy maintenance, and reduced installation costs. These panels consist of two steel sheets with injected polyurethane foam, resulting in a uniform, lightweight, and highly versatile end product.

When choosing a refrigeration panel for cold rooms, it is important to consider the level of thermal insulation and air tightness required to select the appropriate thickness. The thickness can range from 80mm to 200mm, and the choice will depend on the budget availability and cooling needs of the project at hand.

Cold storage rooms for chilling (+0°C)

For cold rooms that are used to store food or maintain controlled temperatures without the need for a high level of insulation, a thickness of 80mm is usually recommended for both the roof and the facade."

Cold storage rooms for freezing (-1°C to -20°C)

If controlled temperatures below -10°C to -20°C are required and a high level of insulation is needed, it is usually recommended to install refrigeration panels with a thickness ranging from 100mm to 140mm.

Freezing tunnels (-40°C)

For refrigeration systems where temperatures below -20°C need to be maintained, such as laboratories or ultra-freezing of meat or fish, a thickness of between 150mm and 200mm is usually recommended for refrigeration panels.

In refrigeration systems where the temperature is lower than the ambient temperature, it is essential to ensure and maintain minimum energy costs in the cold production systems. Therefore, in addition to choosing the appropriate thickness of the refrigeration panel, it is important to consider the type of enclosure that will be used to achieve optimal thermal insulation.

It is advisable to seek technical advice before starting a refrigeration installation project. A specialized technician can analyze the project's needs and recommend the best option in terms of insulation. 


Any investment made in insulation from the beginning can reduce energy consumption throughout the installation's lifespan. If you need more information or advice, do not hesitate to contact us.
