AEROSOL GENERATION SYSTEM

A non-combustible aerosol provision device for heating aerosol-generating material to volatize at least one component of the aerosol-generating material. One such device includes a heating element at least partially defining a heating zone for receiving at least a portion of a consumable including the aerosol-generating material. The device has a thermal insulator having an inner wall; an outer wall; an insulation region bound by the inner wall and the outer wall, wherein the insulation region is evacuated to a lower pressure than an exterior of the insulation region; and at least one reinforcement to strengthen the thermal insulator, wherein the reinforcement is an internal reinforcement arranged within the insulation region, or is an external reinforcement arranged on a surface of at least one of the inner wall and outer wall outside of the insulation region. The thermal insulator is arranged to extend around at least part of the heating element.
