In the use of greenhouses, what is the role of polycarbonate hollow sheets in insulation?
Polycarbonate hollow sheets are mainly hollow layers, so air will not convect, and heat and cold will not be connected, thus achieving thermal insulation effects. Therefore, hollow polycarbonate sheets are better for vegetable and flower greenhouse ceiling materials.
Then, in addition to this, the advantages of using polycarbonate hollow sheets are:
① The hollow polycarbonate sheet material is light, the cost of steel structure is greatly reduced, the amount of steel used is greatly reduced, resources are saved, and pollution is reduced;
② The polycarbonate hollow sheet has good lighting effect, with a light transmittance of 85%, providing plants with higher photosynthesis and saving a lot of electricity resources;
③ Polycarbonate hollow sheets are non-toxic, pollution-free, and pollution-free high-quality products, providing an excellent environmental foundation for economic crops;
④ The spacing between the insulation layers of polycarbonate hollow sheets can be up to 4mm thick, which effectively prevents air convection, promotes the effect of heat preservation and warmth, and prevents heat loss;
⑤ The effective width of the polycarbonate panel can reach 2.2 meters, and the length can be arbitrarily long. The installation is particularly convenient, simple and practical. More than 5,000 square meters can be laid in one day.
