The four-layer polycarbonate sheet is made of  virgin bayer materials. Its grid structure combines engineering structural mechanics and optics. It has the advantages of light weight, good rigidity, heat preservation, durable use, and beautiful appearance. It is an ideal choice for building lighting materials.

The hollow structure improves the material carrying capacity. For example, the thickness of the multiwall polycarbonate sheet can reach 20mm, which is 3.5 times higher than the carrying capacity of the 10mm twin wall polycarbonate sheet. In the design, the multiwall polycarbonate sheet can use a larger span than the double wall polycarbonate sheet, which not only saves the structure cost, but also makes the field of vision wider and improves the visual grade of the building. It is very suitable for stadiums, exhibition centers, industrial plants, stations, etc. The application of large-scale public buildings is more transparent and energy-efficient.

A comfortable thermal environment is one of the important goals of successful architectural design. In order to maintain the stability of the indoor thermal environment, it is necessary to limit the heat exchange between the building and the surrounding environment and reduce the transfer of heat energy.

The energy-saving characteristics of the multiwall polycarbonate panels are shown in the following aspects:

The thermal conductivity of polycarbonate raw materials is 0.2W/m.K, which is better than glass, etc. ( 0.8W/m.K for flat glass and 40W/m.K for construction steel );

The grid structure of the four-layer solar panel forms the upper and lower air compartments, and the thermal conductivity of the air is extremely small, which can improve the overall thermal insulation performance of the material, which is extremely beneficial for applications that require thermal insulation such as agricultural greenhouses.
