Why are the windows of most houses in China open outside? Can I change it to an inner opening?

In fact, this question is completely unnecessary. According to national regulations, windows must be opened in high-rise buildings with more than seven floors, and the lower glass and glass larger than 1.5 square meters must be toughened. So it's not where you want to drive, but whether you follow the rules. Once the structure is more complicated, the operation is inconvenient, the cost is higher and the use is less. Sliding window has simple structure, convenient operation and low cost, and it still has a market in the south. Disadvantages are poor sound and heat insulation, no environmental protection, and will be gradually eliminated; There is also an American opening.

China's economic and cultural development. With the application and promotion of foreign doors and windows in China (mainly in Europe) and the continuous development of domestic door and window materials, the development of domestic doors and windows is mainly divided into tooling market and the growing market below five floors. If the podium really needs to be multi-storey, we can consider a step-by-step approach. If there is no podium on the sidewalk, you can set a flower pond with a width of more than 5 meters along the building. This can effectively prevent people from falling from tall buildings. It is strongly recommended that the Ministry of Construction be made compulsory.

Casement windows are divided into external windows and internal windows. External window refers to a casement window in which part or all of the sash protrudes outward after the sash is opened. Inner window refers to the casement window that enters the room after the sash is opened. A sliding window is neither an external window nor an internal window. I remember that "Code for High-rise Buildings" only stipulates that high-rise buildings can't use flat push windows, because there is no fixed connection between windows and window frames, and it is easy to push them off with a hard push. However, there is no restriction on opening the hinged fixed window internally or externally.

The left and right sliding windows are very simple in structure and easy to operate. At present, it is basically used in aluminum alloy and plastic steel windows, and the overall cost is very low, which is also at the low end of doors and windows. At present, this kind of door and window opening form is widely used in the south, and its disadvantage is that the windows open inward. One is safety, and the other is beauty. If the window opens outwards, strong winds can easily blow it off and hit people downstairs. Secondly, if it opens outward, the size of the opening will be different, which will affect the appearance of the whole building.
