Polycarbonate hollow sheets are generally divided into double-layer and multi-layer. Why is it divided like this, and what is the difference?
Comparing multiwall polycarbonate sheets with double wall polycarbonate sheets, the purpose of choosing multiwall polycarbonate sheets is to have good thermal insulation, high force or bearing strength, and not easy to damage. However, among the customers who have considered the twinwall skylight roofs that have been purchased and installed before, how many times have they reported that the polycarbonate sheets have poor thermal insulation and poor strength? So now you increase the cost area and choose multi-layer sun panels. Is it cost-effective?
Advantages and disadvantages of multiwall polycarbonate sheets and twinwall polycarbonate sheets:
1. Advantages of multi-layer polycarbonate sheets: more layers, better sound insulation, better heat insulation, and stronger support than two layers. Disadvantages of multiwall polycarbonate sheets: For canopies with arched curvatures, the more layers of the panels, the greater the impact on the service life, because it has a greater bearing force when it is bent and stressed.
2. Cost comparison: The cost of multiwall polycarbonate sheets is much higher than that of two-layer sun panels because of the large amount of materials used. If the materials are not increased according to the proportion of multi-layer panels, the wall thickness of the multi-layer structure polycarbonate sheets will not keep up but become thinner, which will further affect the quality of use. In fact, the key to the service life of the polycarbonate sheet lies in the top layer, not the number of layers, so the multiwall sheet does not bring much benefit to the service life.
3. Under what circumstances is it better to choose a multiwall pc sheet? When constructing the skylight, the density of the keel is too large, the spacing between the purlins is large, or when it is used for indoor facade partitions to increase the hardness of the plane and isolate noise, the use of multiwall polycarbonate sheets can play a very critical role in these situations.
Whether it is a multiwall or twinwall polycarbonate sheet, choosing a PC polycarbonate sheet that suits you and has a high cost performance is a necessary skill in our lives.
