A double-walled curtain of pleated material, wherein at least one fold of pleated material of the one wall is connected by means of two parallel connecting strips (10,11) to one or more folds of the other wall for the forming of a module, whereas the outward facing surfaces of the connecting strips bear co-acting coupling means, said modules being adapted to be extruded, whereby the height and width of the curtain can be determined in a simple manner, due to the tubular and endless length of material.
