1, beautiful: the aluminum shape of the broken bridge with inner and outer flat frames is beautiful and atmospheric. No matter standing outdoors or indoors, you won't see the fan frame, and the facade outside the window is uniform.

2, windproof: after closing the window, the gap between the inner and outer flat frames is small, and the sealing performance is good, so there is no need to worry about the phenomenon of wind running. If the gap between doors and windows is large, when people stand by the window in rainy season or winter, cold air will swish into the room, thus affecting the thermal insulation performance.

3, long life: can extend the service life of doors and windows. Because the inner and outer frames of the sealing strip are flat, it will reduce the contact with the outside world, protect the sealing strip well and reduce the possibility of water seepage in the window. For broken aluminum doors and windows, sealing strips are very important. Once the sealing strip is aged, the overall thermal insulation effect will be affected.

4. Safety: Turn on the fan outward, so that children won't bump their heads because the fan protrudes, and the anti-theft performance is better.

Disadvantages:

1. The locator cannot be installed, because the inner and outer flat frames adopt hidden hinges, and ordinary locators cannot be installed on doors and windows. If the window encounters strong wind when it is opened, it is likely to cause the window to move instantly. If the outer window is flush, the hinge is used, so there is no such phenomenon.

2. The later maintenance is inconvenient, because the broken bridge aluminum window is double-layer glass or triple-layer glass, and the glass is very heavy. If it is used for a long time, it will drop slightly, which will affect the smooth switching.

3, the price is relatively higher than ordinary doors and windows, but the service life is worth it.
