Selection of PU sandwich panel thickness in cold storage construction

During the construction of cold storage, choosing the right material is the key to ensuring the performance and service life of the cold storage. Among them, PU sandwich panels, as a common cold storage building material, have an important influence on the overall thermal insulation effect of the cold storage.

Basic characteristics of PU sandwich panels

PU sandwich panels, namely polyurethane sandwich panels, have been widely used in cold storage construction for their excellent thermal insulation performance and stable chemical properties. It uses two layers of fiberglass panels as panels, and fills the middle with hard polyurethane foam as the core material, and is made by high-pressure composite technology. This structure makes the PU sandwich panel have excellent thermal insulation performance, corrosion resistance, and anti-aging characteristics.

Principles for selecting the thickness of PU sandwich panels

In the construction of cold storage, the selection of the thickness of PU sandwich panels should follow the following principles:

• Thermal insulation performance: The thickness of the PU sandwich panel directly affects its thermal insulation performance. Generally speaking, the greater the thickness, the better the thermal insulation performance. However, too thick a sandwich panel will also increase the construction cost and installation difficulty. Therefore, when choosing the thickness of the sandwich panel, it is necessary to comprehensively consider the thermal insulation performance and cost-effectiveness.
• Load-bearing capacity: The cold storage needs to bear a certain load during use, including the weight of the goods, the activities of personnel, etc. Therefore, when choosing the thickness of the sandwich panel, it is necessary to consider its load-bearing capacity to ensure the safety and stability of the cold storage.
• Use environment: The use environment of the cold storage includes factors such as temperature, humidity, and corrosiveness. These factors will affect the performance and service life of the sandwich panel. When choosing the thickness of the sandwich panel, it is necessary to comprehensively consider the use environment and select the appropriate material and thickness.

Applicable scenarios of PU sandwich panels of different thicknesses

• 50mm-100mm thickness: suitable for general small cold storage or refrigeration equipment, such as refrigerators, freezers, etc. These equipment do not require high thermal insulation performance and are used less frequently, so thinner sandwich panels can be selected.
• 100mm-150mm thickness: suitable for medium-sized cold storage or scenarios requiring higher thermal insulation performance. These cold storages usually need to store a large amount of goods and need to maintain a constant temperature, so thicker sandwich panels need to be selected to improve thermal insulation performance.
• Thickness above 150mm: suitable for large cold storage or scenarios requiring extremely high thermal insulation performance. These cold storages usually need to store a large amount of goods and need to maintain a constant low temperature environment for a long time, so thicker sandwich panels need to be selected to ensure thermal insulation performance.

In the construction of cold storage, the selection of PU sandwich panel thickness needs to be comprehensively considered according to the specific situation. When choosing, it is necessary to fully consider factors such as thermal insulation performance, load-bearing capacity, and use environment, and select the appropriate thickness according to the actual situation. At the same time, it is also necessary to pay attention to the selection of products from regular manufacturers to ensure that the quality and performance of the sandwich panels meet the requirements. Through reasonable selection and use, the thermal insulation performance and service life of the cold storage can be improved, providing better protection for the storage and preservation of goods.
