AN INFLATED PLASTICS ROOF FOR A MULTISPAN GREENHOUSE |
| Author: | G.E. Bowman |
| Abstract:
A greenhouse incorporating a double-layer inflated roof offers thepossibility of worthwhile fuel saving, minimum loss of light due to structural members, easy access and such a building is readily fan ventilated. Against these advantages must be set the problem of large static forces in the structural members, loss of light reflected by the second plastics film and the difficulty of handling large areas of film plastic during construction or re-cladding. Consideration is given to the forces existing in curved films and in the supporting structure, in relation to weather and crop loads. Experimental forms of inflated-roof greenhouse are described and some results quoted for heat loss and light transmission. | |
