ABSTRACT:
An inflatable movable ceiling or partition is installed in a greenhouse to limit the interior volume of the greenhouse which must be heated by artificial means. The tubes are inflatable transparent plastic tubes, which are arranged longitudinally in the greenhouse, and when inflated form a complete false ceiling partition. When the tubes are deflated, they may be pushed back to lie against the sides of the greenhouse. The ceiling or partition is formed of adjacent cylindrical inflatable tubes which are in fluid communication by means of an inventive jumper system which forms an airtight seal between adjacent members. The jumpers may be installed at the time the system is installed in the greenhouse and the ends of the cylinders sealed by wire ties or they may be taped.
