1.high strength,Minimum Shrinkage 2.Compounded aluminum films and PE films. 3.Shading rate 80% Energy saving 70%High reflective inside screen can still reflect strong sunlight when we use it in the greenhouses. In the hot summer, we use it in the daytime, and it plays the role of cooling and water-saving; can reduce the temperature about 4-7 . In winter it can reflect more than 70% formation hotline, this makes the indoor heats reflect to the surface of crops. It plays the role of warm keeping and energy-saving, can raise the temperature about 3-6 and also can reduce energy consumption costs. On the other hand, the unique structure of this product can avoid condensation of the leaves so that it reduces crop diseases as well as products diffuse reflectance can make crop growth proportionally. The endurance of inside screen is an essential indicator; in solar radiation, there is 7% of ultraviolet (spectroscopy<0.4μm), but it is very destructive to shading materials, so products must be added a certain UV additive to reach its service life.
