Polyurethane insulation panel is also called PU panel. It is a bi-metallic, single-metallic or non-metallic composite panel with rigid polyurethane foam as the thermal insulation layer. It is a highly efficient and energy-saving building envelope material with wide uses and great potential. It is also advocated and promoted by the Ministry of Construction. A new type of energy-saving panel that can be applied to a variety of different building needs.

Pu panel wall has moisture-proof and waterproof properties.


1. Pu panel has low thermal conductivity and good thermal performance.

2. Pu panel wall has moisture-proof and waterproof properties.

3. Polyurethane insulation panel is fireproof, flame retardant and high temperature resistant. Polyurethane is a flame-retardant, self-extinguishing material after adding flame retardants. In addition, when polyurethane burns, it will form carbon deposits on the surface of the foam. This layer of carbon deposits helps isolate the foam below.

4. Due to the thermal insulation properties of polyurethane sheets, under the same insulation requirements, the thickness of the building's outer envelope can be reduced, thereby increasing the indoor use area.

5. Strong resistance to deformation and not easy to crack.

6. The porosity structure of polyurethane materials is stable and basically closed-cell structure. It not only has thermal insulation performance, but also has good freeze-thaw resistance and sound absorption.

7. Low overall cost performance. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by significant reductions in heating and cooling bills.


Polyurethane panels are widely used in large industrial plants, cold storages

Application :

Polyurethane panels are widely used in large industrial plants, cold storages, garages, mobile homes, exhibition halls, stadiums, shopping malls, airports, power plants, villas, hospitals, office buildings and other fields

Cold chain transportation:

Agricultural and sideline products often need to go through a long transportation process from the field to the shelf. If the goods are not maintained at a suitable temperature, they can easily deteriorate. Polyurethane panels can be used in insulated compartments of refrigerated trucks to help maintain a constant temperature inside the vehicle, reduce losses caused by temperature differences during product transportation, and help preserve agricultural and sideline foods.

Cold storage warehouse:

As people pay more and more attention to food safety, the number of cold storages continues to increase. In recent years, due to policy support, the number of rural self-built warehouses and county-level large-scale cold storage has continued to expand. Large logistics companies have rushed to build cold chain warehousing and logistics networks. Cold storage panels with polyurethane as the main raw material have been widely used.

Industrial plants and warehouses:

Polyurethane sandwich panels have a series of advantages, such as being lightweight, fast, efficient, and flexible in layout, and have become a better solution in single-story factory buildings. For multi-story industrial plants, in addition to the use of insulation panels for the roof, polyurethane insulation panels can also be used for flexible layout of the exterior walls. The changing colors and shapes of color-coated panels can be used to beautify the appearance of the building. For industrial buildings that require constant temperature and humidity, using insulation panels with better thermal performance than brick walls as enclosure materials can greatly save operating costs after completion.

Purification project:

With the rapid development of industries such as electronics and medicine, the requirements for cleanliness in the production environment are becoming higher and higher. Because the color-coated panel on its surface is not easy to adhere to dust, is easy to clean, and has fewer joints, cleanroom puf panel is used as an interior wall and ceiling material and is widely used in production and working environments with clean requirements.
