? The function of tiger window is introduced in detail.

When it comes to tiger windows, Suzhou people have the most say. This kind of tiger window specially opened on the roof can still be seen in Pingjiang Road, Suzhou. Pingjiang Road is an old street that can best reflect the old characteristics of Suzhou ancient city, and it has serenity, elegance and simplicity that are rare in other streets. Next, I will take the vast number of consumers and friends to have a good understanding of this tiger window.

The ancients in China paid great attention to orientation when building houses, that is to say, houses must face south and face the sun, and only when facing the sun will the interior be bright. However, although the old house faces south, the internal light may not be enough, because the windows were small and the panes were too dense, which affected the lighting. People will install skylights on the sloping roofs facing south to increase the lighting. Skylight was invented only when glass appeared in the late Qing Dynasty, with a short history. The earliest skylight was just a newspaper-sized square hole on the roof, covered with a piece of glass and sealed with putty. It's just that this skylight is also defective, and it can only light but not ventilate.

The clever craftsman later opened a square or rectangular hole on the roof larger than the skylight, and then built a small house on the square hole. The roof of the small house is tilted to the north, in the shape of a large roof tilted to the south, with walls built on both sides. On the side facing the south eaves, one or two windows are vertically installed. This can not only light the room, but also open the window for ventilation. People look from a distance, this sudden window is like an open tiger's mouth, and it is dark inside, so it is called "tiger window". Because the tiger window is the evolution of skylight, it is also called "tiger window".

The interior height of a house with tiger windows is relatively low, and it is generally opened in the insulation layer of the attic or bungalow. There are many bungalows in traditional buildings in Suzhou. In the past, the upper floors or attics of bungalows were generally uninhabited and only used for ventilation and heat insulation, or for stacking sundries. Therefore, there will be a transom inside to prevent the upper floor from being hot and humid, leading to moldy piles and rotten roofs. In the late Qing Dynasty and the early Republic of China, the situation was chaotic. Some large families in Suzhou began to evacuate, but the gathering of foreign population increased. The living conditions in Suzhou City tend to be tense, and people begin to share these big families. Some people live in the upper space of low-rise bungalows, and tiger windows come in handy at this time. Because of the low room with tiger windows, people can't stand up straight. There are three forms of window opening on the roof. The simplest one is called patio. Only a piece of newspaper-sized glass is used for lighting. Usually, the outer wall is convenient for rooms with small windows to ventilate on the side, and the room sandwiched in the middle will generally open transoms, which can not only light but also ventilate the windows. Households with good conditions can open a tiger window. The purpose of opening transoms or tiger windows is to prevent the upper floors from being damp and sultry, resulting in moldy wooden stakes and rotten roofs. This kind of bungalow still existed in rural areas before the 1990s.

At the beginning of last century, with the increase of industrial population in Shanghai, living conditions became more and more tense. Someone came up with the idea of using the thermal insulation space on the upper part of the bungalow. The method is to enlarge the skylight above and build walls on both sides to make the window surface perpendicular to the normal window, so that people can not only stand straight in the middle, but also stand on the side, expanding the living area.

Tiger window is the homonym of roof in Polish. In some two-story Shikumen houses, the skylight on the roof is designed as a tiger window. So the room with the tiger window in the south is called the three-story pavilion, and the room on the kitchen under the balcony of the North Annex is called the two-story pavilion. The three-story pavilion is too hot in summer. Shanghainese once laughed at the shirtless people who lived in the three-story pavilion in their early years.

After the opening of Shanghai, many British people came to live in Shanghai, and they brought English architecture. In northern Europe, the climate in Britain is cold and snowy. In order to avoid the pressure of snow on buildings, most of their houses are in the style of high slopes and spires. In order to increase lighting and ventilation, many roof windows have been opened on the roof. Roof in English is "roof", which sounds very similar to "tiger" in Shanghai dialect, so this kind of window opened on the roof is pronounced "tiger window" by Yang Jingbin in English. After the 1920s, with the aggravation of housing difficulties in Shanghai, Shanghainese used the high space and sloping roof on the second floor of Shikumen residence to build an attic between the second floor and the roof. In order to increase the lighting and ventilation in the attic, they also opened windows on the roof, also called "tiger windows". So "tiger window" generally refers to the roof window in Shanghai Shikumen dwellings.
