<；P>；PROBLEM TO BE SOLVED: To provide a structure of a hot-house lining film enabling high heat-insulation effect to be expected and aiming at cutting heating costs. <；P>；SOLUTION: The structure of a hot-house lining film is formed as follows: hanging down a first lining film 10 to be supported with an upper-end supporting member 40 followed by fixing a spacer member 30 to a framework material 110 via the first lining film 10； and supporting a second lining film 20 with the upper-end supporting member 40 to make the film hang down so that the second lining film 20 is disposed at the inside of the spacer member 30 because the spacer member 30 having a prescribed thickness lies at the inner surface of the first lining film 10. Such a structure makes an air layer between the first lining film 10 and the second lining film 20 so as to improve heat-insulating effect relative to that by a conventional means using a single lining film. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
