<p>A greenhouse, with cross-members in its framework to separate the plants from the roof space, is internally thermally insulated with insulating plastic films on a carrier film. The carrier film is fastened in the cultivation space, with its insulating layer it covers over the plants and the walls of the greenhouse and can be fully or partly drawn across over the cultivation area. Arrangement minimises heat loss without interfering with plant care; heated vol. of air is minimised and hence is easily raised to desired temp. with normal ventilation available.</p> |
