Polyurethane sandwich board is an innovative building material that consists of two metal sheets (usually galvanized steel plate, color steel plate, etc.) and a polyurethane hard foam core material sandwiched in between. This unique structure gives the polyurethane sandwich board the strength of metal sheets and the excellent performance of polyurethane core material.
The polyurethane rigid foam core material is produced by mixing isocyanate and polyol under specific conditions. The resulting material has a uniform and fine closed cell structure on the inside, which enhances the board’s insulation properties.
The production process of sandwich panels is highly advanced, which ensures that the layers are tightly combined and secured firmly together. This creates a solid and durable panel that provides high-performance results for construction purposes.
One of the most distinctive features of polyurethane sandwich panels is their excellent thermal insulation performance. The thermal conductivity of polyurethane is extremely low, typically ranging from 0.018-0.024 W/(m · K). This is significantly lower than that of other traditional insulation materials. The polyurethane's closed-cell structure is responsible for this low thermal conductivity, which effectively reduces heat conduction, convection, and radiation. This feature enables the building to maintain a warm temperature during winter and cool temperature during summer, providing an excellent opportunity for energy saving and emission reduction.
Polyurethane sandwich panels also provide excellent fire resistance. By adding the appropriate flame-retardant materials, the sandwich panels can achieve different fire ratings such as B1 (flame retardant) or even A2 (non-flammable). In case of a fire, the sandwich panels can effectively delay the spread of the fire, inhibit the spread of the flame, reduce heat release, and smoke generation. This provides valuable time for personnel evacuation and fire rescue, ultimately improving the fire safety of the building.
In terms of water and moisture resistance, polyurethane sandwich panels are equipped with two features. First, polyurethane itself is a hydrophobic material, which reduces water penetration. Second, the closed-cell structure of the sandwich panels also prevents water from entering. The sandwich panels provide excellent protection against the erosion of rain, snow, and humid air. This feature will prevent water from entering the interior of the temperature retaining core material, which avoids any problems such as thermal insulation performance decline, mold, rot, or any other issues caused by moisture. This ensures the long-term stability of the thermal insulation system.
Polyurethane sandwich panels are known for their high strength and stability. The upper and lower layers of sheet metal provide the necessary strength to withstand external forces such as wind loads, snow loads, and the weight of personnel and equipment. The polyurethane core material provides the sandwich panels with a certain elasticity and toughness, making it difficult to deform or damage them under external forces, ultimately ensuring the stability of the building structure.
Another great advantage of polyurethane sandwich panels is their excellent sound insulation effect. The sandwich panels are very effective in reducing the interference of external noise on the indoor environment, leading to a quiet and comfortable living and working space for people. The sound insulation effect depends on the thickness and density of the sandwich panels to a certain extent, and the sound insulation performance of thick and moderate density sandwich panels is better.
Finally, polyurethane sandwich panels are easy to install thanks to their standardized sizes and specifications, light weight, and easy handling. A variety of installation methods can be used on the construction site, such as splicing, anchoring, and other processes. The installation process is simple and fast, which effectively shortens the construction period and lowers the overall cost of construction. The outer metal sheet of the sandwich panels can have various colors and surface treatment methods such as galvanized or color coating. These features make the sandwich panels not only beautiful and generous but also highly durable, able to resist the erosion of natural factors such as ultraviolet light, chemical substances, and temperature changes. This durability extends the lifespan of the sandwich panels.
Polyurethane sandwich panels are versatile and can be used in various building types. Its main application fields are industrial buildings, commercial buildings, residential buildings, cold chain logistics, and agricultural facilities.
Polyurethane sandwich panels are widely used in industrial plants, warehouses, logistics centers and other buildings. In industrial plants, it can provide stable temperature and humidity conditions for the production environment and meet the requirements of industrial production on building strength and fire performance. For warehouses and logistics centres, polyurethane sandwich panels protect goods from changes in temperature and humidity, ensuring quality.
Polyurethane sandwich panels are also used in commercial buildings such as shopping malls, supermarkets, hotels, and office buildings. In shopping malls and supermarkets, it helps to maintain a comfortable indoor shopping environment and reduce energy consumption. In hotels and office buildings, it can provide good sound insulation, thermal insulation, and fire protection performance, creating a high-quality environment for customers and office workers.
In residential buildings, polyurethane sandwich panels are used for external wall insulation, roof insulation and indoor partition. The use of polyurethane sandwich panels on external walls can effectively improve the residential thermal insulation performance and reduce energy consumption. It can also protect the roof structure and extend the service life of the waterproof layer of the roof when used for roof insulation. When used for indoor partitions, it is both aesthetically pleasing and can play a certain role in sound insulation.
The construction of cold storage is one of the important application fields of polyurethane sandwich panel. Its excellent thermal insulation performance can ensure the stability of the temperature in the cold storage, reduce the energy consumption of refrigeration equipment, and ensure the storage quality of refrigerated and frozen goods. At the same time, the moisture-proof and antibacterial properties of the sandwich board are also conducive to maintaining the sanitary environment of the cold storage.
Polyurethane sandwich panels are also used in agricultural greenhouses, agricultural products warehouses and other facilities. In the greenhouse, it can adjust the indoor temperature, humidity and light to create a suitable environment for crop growth. In the agricultural products warehouse, the freshness of agricultural products can be maintained and the storage period can be extended.
