Claim 0:
1. An aerosol-generating apparatus comprising:
a mouthpiece having an inhalation outlet; and
an aerosolizing thermal reactor having an air inlet upstream of an aerosol outlet, wherein the aerosol outlet is upstream of the inhalation outlet, the aerosolizing thermal reactor comprising
an aerosolizable substance chamber having a chamber outer wall surrounding a chamber inner volume, the chamber inner volume located upstream of the aerosol outlet,
a thermal distribution casing surrounding the aerosolizable substance chamber, the thermal distribution casing comprising a multi-layer construction including a first metal layer and a second metal layer,
the first metal layer composed of a first metal material having a first thermal conductivity, the second metal layer composed of a second metal material having a second thermal conductivity, and the first thermal conductivity being at least double the second thermal conductivity, and

an air preheating passage located downstream of the air inlet and upstream of the aerosolizable substance chamber, the air preheating passage surrounding the aerosolizable substance chamber, and the air preheating passage being defined by an air gap between the chamber outer wall and the thermal distribution casing.
