PHOTOMETRIC PROPERTIES OF DOUBLE WALL PLASTICS USED AS COVERING FOR GREENHOUSES

A. NISEN, S. COUTSSE
The photometric properties of some "double wall insulating" plastics used as greenhouse cover were established following the general technical card of the NBN 894.

A first approach of agronomic presentation of these data is proposed.

Sharp differences appear between the materials actually on the market, in relation with their chemical composition, their fabrication, their thickness …

The importance of the knowledge of the reflection properties of the materials and of their transmission factor in diffused light (esp. cloudy sky) is shown.
