A method of constructing a heating chamber for an aerosol generation device includes providing a side wall of the heating chamber, providing a heater, and arranging the heater to be in thermal contact with the side wall of the heating chamber. The method may also include attaching a heat shrink layer to the outward facing side of the heater, and heating the heat shrink layer to a temperature such that the heat shrink layer contracts to compress the heater against the side wall. The heating chamber for the aerosol generation device includes a side wall defining an interior volume of the heating chamber, and a heater in thermal contact with the side wall, as well as a heat shrink layer under tension, compressing the heater against an outwardly facing surface of the side wall.
