One year after installation, the problem net looks like this:

    Aluminum foil is an important guarantee for the realization of the screen function. The oxidation or corrosion of aluminum foil in the air will cause the loss of the screen function (cooling and heat preservation function); insufficient reflection in summer forces poor cooling effect; in winter or night, rely on aluminum foil reflection The desire for long-wave radiation to increase the temperature of the ground and crops cannot be achieved, and energy-saving and heat preservation cannot be discussed.

     The shrinkage of the curtain means that the insulation screen starts to lose its shading and heat preservation functions and can no longer be used, otherwise the problem will be more

     The shrinkage of the curtain will not only affect the shading effect and energy-saving sealing of the curtain, but also damage the curtain system and the greenhouse itself.
