Abstract
A curtain consists of a web of temperature resistant material that forms a web surface and that may be unwound from a coil that is arranged on a coil core. The curtain web has lateral edge regions on either side of the web so as to be separated by the curtain web's width and upper and lower end edge region. The curtain web includes a first outer web layer, and inner layer of fibrous material that extends over a predetermined length and that forms two opposed surfaces, one of which is adjacent to the first outer web layer. The curtain web also includes a second outer layer that is adjacent to the other surface of the inner layer. The curtain arrangement further includes a supply for a liquid fire retardant that extends with in the region of the upper end edge region and over the width of the curtain so as to supply the liquid to the fibrous material.
