Abstract

Horizontal supports (2) are fitted to the frame of the greenhouse at about the height of a man. A tube or roller (3), which extends the length of the greenhouse, is arranged to roll on the supports. The roller has a sheet (4) of thermally insulating material such as polythene on it. Cords (5) have free ends which pass pulleys (6) and fixed ends wound on and secured to the roller. Cords (7) are similarly fitted. When cords (7) are pulled, the roller moves across the greenhouse so sheet (4) separates the lower part of the greenhouse for economical heating. Sheet (4) is re-rolled by pulling cords (5).
