Cold room panels are mainly used to build the body of cold storage facilities. According to the installation location, it produces cold room wall panels, floor panels and roof panels.
Cold room panels are an important component of the cold storage body. The core function of cold storage panels is to lower the thermal conductivity of the body, isolate heat transfer, and reduce the impact of external temperatures on stored items.

Modern cold storage facilities are relatively complex systems. In addition to the body, cold storage facilities also need to install equipment such as compressors, evaporators, condensers, and throttling devices. Only when all parts cooperate effectively can the cold storage achieve optimal refrigeration performance. People often focus on devices like compressors while neglecting the quality of the storage body, which is a mistake.
If the thermal conductivity of cold storage panels is too high, or if there are gaps in the assembly of the panels, this will affect the insulation performance of the cold storage. Items stored in cold room can easily spoil or deteriorate due to the influence of external temperatures. Devices like compressors need to work frequently, leading to higher electricity bills and even damage to components. Therefore, good cold room panels can not only ensure refrigeration effectiveness but also save energy consumption for users.

Currently, the mainstream cold room panels are polyurethane sandwich panels. Polyurethane materials have strong insulation properties. The higher the cooling demand, the thicker the cold storage panels need to be. For high and medium temperature cold storage, the thickness of the cold storage panels is generally 10 cm, while for low temperature cold storage panels, the thickness is generally 12-15 cm.
The secret of cold room panels
The core indicator that determines the insulation performance of cold storage panels is the foam density of the polyurethane.If the density of the cold storage panels is too large, it will not only increase the amount of polyurethane used, raising costs, but also increase the thermal conductivity of the panels, reducing insulation effectiveness. Conversely, if the density is too low, it will reduce the load-bearing performance of the panels and decrease the structural strength of the body.

After a long period of exploration and experimentation, it has been found that the optimal foam density for polyurethane cold storage panels is between 35 to 43 kgs. Cold storage panels with foam densities in this range can achieve a balance between structural strength and insulation performance.
