The transparent (plastic foil) insulation screen (1) is particularly intended for fitting below and parallel to the glass roof panels of the gable roof of a greenhouse (8-10 is at the ridge end, 35 below the gutter valley end). It comprises sheets (1) which are each dimensioned to cover one or more glass panels and have their opposite horizontal edges reinforced (2, e.g. by rigid rods in their edge seams) to stretch the sheets lengthwise. The two reinforced edges of each sheet are capable of engaging in securing jaws such that the sheet is stretched widthwise. |
