PROBLEM TO BE SOLVED: To provide a simple-structured greenhouse curtain made of double films, which can keep a greenhouse at appropriate temperature and can be smoothly folded without dew condensation when the curtain is cooled.SOLUTION: An upper film constituting the curtain is composed of an agricultural polyolefin special film, and a lower film of the curtain is formed as a fabric processed like a fiber sheet by splitting polyvinyl alcohol resin. The end edges of the curtain spread over the surfaces of front and rear gables of the greenhouse are formed as openings. The ends of the curtain are hung downward while closely in contact with beams near the surfaces of the gables. Ledge lines are attached at regular intervals to the upper surface of the upper film, and ledge lines are attached at narrower intervals than on the upper film to the lower surface of the lower film.
