Why are ancient windows made of paper and won't be broken by strong winds?

Don't worry about this. The general wind can't blow. There is a simple reason. Paper itself is made of fibers and has certain toughness. In the past, windows didn't have such large panes as they are now, and they were all composed of relatively dense small frames. A window will be divided into many small units, so there will be many supporting frames on a piece of paper, so it will not be damaged by the wind. ?

Moreover, enough paper will not get wet by the rain, because our ancestors have considered this problem and made some adjustments in the building structure, extending the eaves and high windows. The role of eaves is to prevent rain (rain falling obliquely) when it is windy and rainy. Generally, the windows made of paper will not be very low, but set in a higher position, so as to give full play to the protective role of the eaves. Even if the above measures are taken, enough paper is made of weak paper, and damage is inevitable. But after all, the cost of paper is low, and the transparency of paper that is old enough will be reduced. Irregular replacement can be a perfect solution. ?

And this paper for windows is different from the paper they usually write. The paper they usually use for writing is Xuan paper, which is easy to faint and absorb water with ink. But the paper used for windows is not like that kind of paper, it is specially treated, just like our oil-paper umbrella. It has certain waterproof function. It's all paper soaked in lard, and the last paper is very tough. The general wind is. So in ancient times, windows could be made of paper.

And in ancient times, there was no wallpaper to make windows. If windows are made of other materials, the effect may not be as good as paper. If you use that kind of cotton cloth or any other material as a window, its ventilation effect is definitely not as good as that of paper, and it can't transmit light. Light transmission is the most important point of windows. If the window can't transmit light, it will have a great impact on the indoor environment.
