PROBLEM TO BE SOLVED: To enhance heat insulation performance of a stile, by restraining the thermal expansion of the stile, in a sash frame.SOLUTION: A panel 102 (a triple glass) is fixed by a stile (a glass fixing frame) formed of a stile 108 and a transverse stile. In the stile 108, a core material 138 is inserted into a central space 154 formed in a side surface part of the panel 102, and an outer space 152 as a heat insulation layer to the central space 154 is formed on an outdoor side more than the central space 154. The stile sandwiches the panel 102 by an outdoor side outer joining part 148 and an indoor side inner joining part 150. The outer space 152 is formed in a side surface part of the outer joining part 148, and a thickness of the outer space 152 is a thickness or more of the outer joining part 148. An inner space 156 is also formed on the indoor side more than the central space 154.SELECTED DRAWING: Figure 5 |
