Abstract: This invention relates to the production of a shading and insulating screen for greenhouses or a protection screen in the open air for market gardening cultivation or horticulture, having a regular check pattern, using a circular loom comprising an insertion device (7) which is provided with a compensator (12).The screens which are obtained have a homogeneous air-permeability which allows the bed to respire uniformly, but they are impermeable to water. They have an increased firmness. The method allows the production of screens made of metallized polyester film capable of filtering the sun's rays.
