PROBLEM TO BE SOLVED: To provide a screen device for thermal insulation in which an air layer for thermal insulation is formed between inner and outer screens stackingly wound on a winding shaft and which prevents a difference in length between the screens on the inner and outer sides from affecting the attitude of a bottom bar.SOLUTION: In this screen device for thermal insulation, the screens 5a, 5b on the inner and outer sides are stackingly wound on the winding shaft 4, and the air layer 7 for thermal insulation is formed between the stacked screens by a guide tube 6. The bottom bar 10 is attached to the bottom end of each screen. Guide parts 12a for guiding the side ends of the bottom bar so that the bottom bar can be lifted in a specified attitude are attached to a rail frame 12 which closes the side end of the air layer between the suspended screens and guides the side ends of the screens. |
