[0029] It should be noted that most windows have multiple mutually separated sub-glasses, such as an openable part and a fixed part.

[0032] Furthermore, if Figure 2 and Figure 3 As shown, the auxiliary component 7 made of glass fiber reinforced polyester also has a cavity, which is filled with a heat insulation component 12;
[0033] Specifically, the heat-insulating component 12 is a plurality of polyurethane foams tightly arranged in the cavity, that is, a plurality of polyurethane foams are used as the heat-insulating component 12 to fill the auxiliary component 7 made of glass fiber reinforced polyester, so that the heat transfer coefficient of the window is more uniform, thereby improving its energy-saving effect;
