Why were concrete visors placed on the windows of some Soviet buildings?

Soviet architecture is a complex and ambiguous phenomenon. For the period 1917-1991, it reflected a wide range of architectural styles from around the world: rationalism, art deco, constructivism, empire and brutalism. Of course, typical buildings did not differ in any artistic delights. However, from the point of view of architecture, its “engineering component” also contained many interesting solutions. For example, the mysterious concrete canopies, which will be discussed today.

The strange concrete structure on the windows of some buildings built during the years of the Soviet Union will cause a slight bewilderment for many modern people. However, even in this case, it becomes quite obvious that the unusual concrete canopies were not installed for beauty at all (typical building cannot boast of it for sure!). In general, in the Soviet Union they were "turned" to ensure that most things were practical. So these visors are made with one single purpose - to improve the ventilation of the room.

The mysterious contraption is called - a lamellar visor. Today it is difficult to say whether it was invented in the USSR. Most often, these could be seen on buildings built for large crowds of people. For example, visors were placed on the windows of some dormitories, clinics and hospitals, buildings of educational institutions. Due to their shape, canopies work in the same way as aircraft flaps - they accelerate the movement of hot air up and cold air down. In other words, they organize traction.

It is believed that hitting such a flap, the warm air leaving the room is greatly accelerated and accumulates less in the path of cold air. This design was especially relevant for those buildings, the premises of which have to be ventilated on a regular basis several times a day. As a result, the lamellar visor made it possible to significantly speed up ventilation. It was also good that the people who were in the room spent less time in a potentially dangerous draft.
