Abstract: A rollable and drapeable green-house curtain with insulating power. The curtain comprises double fabric layers separated along their entire length and width and interconnected by means of a plurality of thin and flexible threads sparsely distributed over the surface of the curtain. In the intervals between rows of connecting threads there could be arranged strips of a heat reflecting material, e.g. metallized foil, in order to make the curtain an effective barrier against radiant heat. The curtain is manufactured on a warp knitting machine with two needle bars and the connecting threads consist of connecting stitches between the double fabric paths.
