What's the roof like in the north?

Houses in the north have a great annual temperature difference due to the climate. It's very cold in winter and windy and dusty. Most houses are built with flat roofs for thermal insulation. At the same time, most buildings in the north are built in the lee, and windows are opened in the lee. In addition, due to different geographical and climatic characteristics, the roofs in the north have different shapes, which are all built to adapt to climate change.

Turpan's earth arches and yurts on the grasslands are also quite distinctive. Turpan is called "Huoshao Island". But at night, the temperature drops sharply, and the temperature difference can reach 20 to 30 degrees Celsius overnight. In order to adapt to this climate, the earth arch houses built locally have the characteristics of thick walls, small windows and arched roofs.

In order to adapt to the cold, rainy and windy climate in the northwest grassland, thick wool felt is used on the walls and roofs to keep out the cold. Although the lighting time is short in winter, the rain is scarce, and the roof is made into a round hole, which can be opened and closed like a window. Pull it up during the day, let the sun shine into the room, warm the indoor temperature, and at the same time discharge the indoor smoke and carbon gas; At night, cover the sky cloth and leave the hot air of cooking with milk tea in the room to keep the room warm.

In snowy northern Europe, the roof slopes sharply. On snowy days, the snow will slide down the steep slope and it is not easy to accumulate on the roof. Over time, this minaret-like building has become a beautiful form and has been handed down.
