Thermal insulation comprising a boundary comprising a first boundary section, a second boundary section and a third boundary section which connects the first and second boundary sections together; and an internal insulating region inside the boundary and configured to thermally insulate the first boundary section from the second boundary section; wherein the third boundary section follows an indirect path between the first and second boundary sections. An apparatus configured to volatilize components of smokeable material, comprising the insulation, is also described.

一种绝热构件，其包括：边界，该边界包括第一边界部分、第二边界部分和将第一边界部分和第二边界部分连接到一起的第三边界部分；以及内部绝热区域，其在所述边界内并且被配置为使第一边界部分与第二边界部分绝热；其中，第三边界部分沿着第一边界部分和第二边界部分之间的迂回路径延伸。本申请还描述了一种设备，其被配置为使可抽吸材料的成分挥发并且包括绝热构件。
