SMOKING ARTICLE WITH IMPROVED WRAPPER ABSTRACT OF THE DISCLOSURE The present invention relates to an improved wrapper for a smoking article having a combustible fuel element encircled by an insulating layer and a physically separate aerosol generating means as well as to smoking articles employing such wrappers. The wrapper encircles at least a portion of the insulating layer for the fuel element and comprises a permeable sheet material which during burning of the fuel provides a coherent layer to assist in controlling the amount of peripheral air to the fuel element during smoking. Preferred smoking articles which employ the wrapper of the present invention have a short fuel element, a physically separate aerosol generating means including an aerosol forming material, an insulating material around the fuel element, a relatively long mouthend piece, and a combination of sheet materials as the wrapper comprising an innerwrap which after lighting of the fuel element burns away to a high permeability non-coherent ash and an outerwrap which upon lighting fuses to form a coherent ash which assists in controlling the amount of peripheral air to the fuel element during smoking.
