Abstract

1. Product in sheet form for the filtration of the illumination in greenhouses, composed of a layer of metal such as aluminium inserted between two transparent plastic sheets (1 and 4), characterized in that the metal layer comprises regularly distributed gaps (3), leaving therebetween metal zones (2), of which the total surface is such that the product allows an illumination of between about 1 and 50% of that which it receives, to pass through the gaps (3).
