PROBLEM TO BE SOLVED: To change a heat insulating function by applying the constitution that either a sash having each stile of non-ferrous metal or a sash having each stile of non-ferrous metal interior and exterior members jointed via a heat insulating material is coupled to a window frame made of non-ferrous metal. SOLUTION: An exterior member 12A of aluminum and an interior member 12B of aluminum are connected to each other via a heat insulating material 12C of urethane resin, thereby forming a heat insulating window frame 1. Also, each of an aluminum upper frame, an aluminum lower frame 42 and the aluminum frames of right and left jambs are jointed to one another like a square frame, thereby forming a general window frame 2. Furthermore, single plate glass is coupled to the aluminum window frame, thereby forming a general single panel sash 5. Multilayer glass is coupled to the aluminum window frame, thereby forming a general multilayer sash 6. Also, a plurality of aluminum members are jointed to each other via heat insulating members 53C and 54C, thereby forming a heat insulating multilayer sash 7. Then, the general single panel sash 5. the general multilayer sash 6 or the heat insulating multilayer sash 7 is combined with the heat insulating window frame 1 or the general window frame 2, thereby forming sash wiradows having a different heat insulating function. |
