    Abstract: A multi-segment component for an aerosol-generating article is provided, the multi-segment component including: a combustible heat source; an aerosol-forming substrate downstream of the combustible heat source; and a wrapper circumscribing a rear portion of the combustible heat source and at least a front portion of the aerosol-forming substrate, a front portion of the combustible heat source extending beyond the wrapper so that the front portion of the combustible heat source is exposed during use; and an intumescent coating on all or part of the front portion of the combustible heat source, the intumescent coating being configured to form a heat insulating layer on the front portion of the combustible heat source in response to heating by the combustible heat source.

    Abstract: There is provided a heat source for a smoking article, including an upstream end and an opposed downstream end, and further including a combustible carbonaceous core and an integral, non-combustible, thermally insulating, peripheral layer. The core extends from the upstream end of the heat source the downstream end of the heat source. The peripheral layer extends from the upstream end of the heat source only part way along the length of the heat source and circumscribes an upstream portion of the core.

    Abstract: A smoking article is provided, including a combustible heat source having opposed front and rear faces; an aerosol-forming substrate downstream of the rear face of the heat source; a first heat-conducting element including one or more radially inner layers of heat-conductive material overlying a rear portion of the combustible heat source; and a second heat-conducting element including one or more radially outer layers of heat-conductive material overlying at least a portion of the aerosol-forming substrate, such that the one or more radially outer layers of heat-conductive material do not overlie the one or more radially inner layers of heat-conductive material.
