How to choose the correct thickness of refrigeration panel for a cold store

Cold rooms have high energy consumption, so choosing the right thickness of cold room panels is key to maintaining the required temperature and optimal energy use.

The most commonly used system for building cold rooms is prefabricated cold room panels. Compared to traditional insulation, it offers a series of advantages such as quick assembly, easy maintenance, and reduced installation costs. This system consists of two steel sheets injected with polyurethane foam, resulting in a homogeneous, lightweight, and highly versatile final product.

When choosing cold room panels for your cold storage, it is important to know the thermal insulation and airtightness required to select the most suitable thickness. These can range from 80 mm to 200 mm thick. The chosen thickness will depend on the budget available for the project and the refrigeration requirements.

Cold Rooms for conservation (+0 °C)

A thickness of 80 mm is recommended for the roof and facade of cold rooms intended for food storage or controlled temperatures that do not require high insulation.

Cold Rooms for freezing (-1ºC to -20 °C)

For installations that require controlled temperatures below -10ºC to -20ºC and high insulation, it is recommended to install a cold room panel with a thickness of 100 mm to 140 mm.

Freezing tunnels (-40 °C)

The ideal thickness for cold storage facilities where temperatures below -20ºC need to be maintained, such as laboratories, meat or fish ultra-freezing, among others, is between 150 mm and 200 mm.

As these are cold storage facilities that are at a temperature below ambient, it is essential to guarantee and maintain the minimum energy cost of the cold production systems. Therefore, in addition to the thickness of the cold room panel, the type of enclosures to be used for optimal thermal insulation must be considered:

Cold storage doors
High-speed doors
Other accessories (Air curtains, etc.)

Before embarking on a project, you should seek expert advice. Their job is to analyse your facilities and recommend an option that best suits your needs, as any investment in insulation will, right from the start, reduce energy consumption throughout the facility’s operational lifespan.
