PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermal insulation extrusion and a thermal insulation extrusion capable of shortening time necessary for injecting a foaming resin material.SOLUTION: A thermal insulation extrusion 1 comprises an aluminum extrusion 10 including a first extrusion part 20, a second extrusion part 30, and a cavity forming part 40. The cavity forming part 40 has an injection opening 43 along the longitudinal direction of the first extrusion part 20 and the second extrusion part 30. The cavity forming part 40 also has a cavity 40A, coupled to the injection opening 43, between the first extrusion part 20 and the second extrusion part 30. The cavity forming part 40 comprises a first extrusion part 20 side portion and a second extrusion part 30 side portion disposed with a space 44 therebetween. A thermal insulation material 50, consisting of a foaming resin material, is disposed in the cavity 40A.SELECTED DRAWING: Figure 1 【課題】発泡樹脂材の注入に要する時間を短縮できる断熱形材の製造方法および断熱形材を提供すること。【解決手段】断熱形材１は、第一形材部２０と、第二形材部３０と、第一形材部２０および第二形材部３０の長手方向に沿った注入口４３を形成しているとともに注入口４３につながったキャビティ４０Ａを第一形材部２０および第二形材部３０間に形成したキャビティ形成部４０とを有したアルミ製形材１０を備える。キャビティ形成部４０は、隙間４４を隔てて配置された第一形材部２０側部分と第二形材部３０側部分とによって構成される。キャビティ４０Ａには、発泡樹脂材によって形成された断熱材５０が配置されている。【選択図】図１
