Abstract

A method for manufacturing an insulating material is disclosed. One such method comprises the steps of: providing an inner wall configured to at least partially define a heating zone for accommodating an aerosol-generating material—the inner wall comprises a heating material capable of being heated by penetration by a changing magnetic field—and providing an outer wall—the outer wall at least partially surrounds the inner wall along its length, and an insulating region is formed between the inner wall and the outer wall comprising different materials. The method also comprises the steps of: attaching a portion of a first bonding material to the inner wall under atmospheric pressure; attaching a portion of a second bonding material to the outer wall under atmospheric pressure; exhausting the insulating region to a pressure lower than atmospheric pressure; and closing the insulating region by bonding the first bonding material and the second bonding material together.
