Also, as shown in the same figure, the empty grid body 93 is eliminated and the first additional vertical frame is used as the external frame,
The appearance is made to look solid, and the lattice body 93 can be attached at a later date as required. Furthermore, in the figure, the same effect can be obtained by omitting the lattice body 93.

As is clear from Fig. 6, even as a single-glazed window, the bulging portion 59 makes the window frame look solid and luxurious, which is desirable, and as a double-glazed or triple-glazed window, it is possible to easily enjoy changes by retrofitting it, and there is a great advantage in that no damage is done to the exterior wall or the building frame. And as a multiple-glazed window, a window with excellent soundproofing and heat insulation properties is obtained.

As described above, in the present invention, the vertical frame 58 of the basic window frame 1, which is directly fitted into the opening 3, is integrally formed with the bulge 59 that extends outside in the shape of a frame, so that it can be used as a single-pane window. A window frame that has a solid appearance and is desirable in terms of design as well as being lightweight and strong can be obtained. Furthermore, since the vertical frame 77 of the additional window frame 2, which has the fitting recess 78 opened indoors, can be retrofitted by fitting it onto the bulge 59 of the basic vertical frame 58, the connection strength is high.
It also allows for reliable retrofitting, and allows for easy and quick work without damaging the exterior walls or building blocks. Furthermore, it is easy and convenient to add side grilles and handrails later. In addition, a window with excellent soundproofing properties as a double- or triple-pane window and contributing to energy saving can be obtained, and a window with a three-dimensional effect and a variety of designs can be obtained.
