Plastics for double screen greenhouses amplify the thermal effect of the cover and in turn allow for maximum light transmission towards the greenhouse interior.
Their purpose is to create an air chamber, or insulation, between the cover plastic and the double chamber that regulates the temperature, reducing temperature variations and mitigating plant stress.
Another advantage is that the double screen protects the crop from potential dripping from the greenhouse cover, especially in “ridge and furrow” structures.
They can be manufactured with 10 or 15 mm-diameter perforations, to improve ventilation inside the greenhouse and in turn, avoid water from pooling on top of the double chamber.
