Polyurethane insulation panels in cold stores

Insulating panels in high quality designs find their wide application. Whether for building facades, roofs, ceiling systems, partition walls or spaces that require special requirements. In this article, we will look at the advantages and technical properties of polyurethane panels, which are commonly used in cold stores, and consider how they contribute to reducing energy costs and improving the operating parameters of cooling systems.

Polyurethane insulation panels are an effective solution for cold stores that require reliable thermal insulation and energy efficiency. Thanks to their excellent insulation properties and low weight, they have become the ideal material for ensuring optimum temperatures in various types of refrigeration facilities, whether they are food warehouses, pharmaceutical storage areas, distribution centres, logistics buildings and many other industries.

What are polyurethane insulation panels?

Polyurethane cold board is a form of insulation that uses lightweight polyurethane as the inner material. The advantage of this material is excellent thermal insulation. It prevents the heat from spreading, which is caused by the temperature difference inside and outside the cold store or box. The outer parts of the panels are made up of sheet metal.

Some models of insulation panels use a concave convex groove structure to improve insulation and airtightness of joints. This structure is specifically designed for cold storage.

Where are polyurethane insulation panels used?

Polyurethane panel is widely used in various sectors, especially for walls, partitions ceilings and roofing. But if we think of polyurethane panels in terms of cooling, they are commonly used in hotels, supermarkets, pharmaceutical, biological, chemical, industrial or mining companies. Of course, the panels are usually tailored to the customer’s specific requirements.

These panels are widely used in the food industry. For example, in cold stores to maintain and regulate temperatures to meet operating standards, typically in the range of -25 °C to +10 °C. This temperature control extends the shelf life of perishable products and ensures that they stay fresh for longer.

Composition of polyurethane insulation panels

Classic polyurethane, so-called PUR, panels consist of two sheets with a filler between them. This is an insulating polyurethane filler. In addition to this filling, PIR foam is also used as an alternative, which has slightly better fire resistance. However, the most fire resistant panels are filled with mineral wool. Depending on the thickness of the insulation, the resistance also varies. This ranges from 15 minutes (EI15, EW15) to 120 minutes (EI120).

Special refrigerated polyurethane panels are designed primarily for the food industry. They are designed with their intended use in mind and therefore the manufacturers take great care to ensure that they comply with demanding hygiene requirements and standards.

Surface of insulation panels in cold stores

The final finish, material and overall design can be adapted to individual requirements. Panel sheets are most often made of aluminium, stainless steel, steel, but it is possible to coat their surface with protective plastic or foil. It is also possible to choose from a variety of sheet metal finishes in terms of visual aspect, from flat surface, fine wave profiling to larger waves. The standard surface material is high galvanised coloured steel sheet with thickness options including 0.4mm, 0.5mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm and up to 1.0mm. All materials are waterproof, corrosion resistant with a long service life.

Health standards

Double-sided antibacterial panels provide an effective solution for food safety. They are resistant to most oils as well as some chemicals and solvents, making them the most cost-effective method for reducing cross-contamination and inhibiting bacterial growth. Among other things, in special cases these insulation panels are coated with an organic coating, the latest in antibacterial technology that offers comprehensive protection for items stored in cold rooms and boxes.

Polyurethane insulation panels and the environment

The use of pentane in the panel manufacturing process. Compared to traditional polyurethane foam methods, it provides higher heat resistance and represents a significant step forward in environmental protection.

The robust tongue-and-groove connection system of the cooler’s sandwich panel ensures a tight connection, minimizing thermal bridging. The result is optimised energy efficiency and thermal management in chiller plant, providing an excellent solution for maintaining energy savings.

Conclusion

Polyurethane insulation panels are proving to be the ideal solution for cold storage cabinets where efficiency, long life and low operating costs are key. Their excellent insulating properties ensure optimum temperature and save energy, which is essential for the efficient operation of refrigerated plants.
