The object of this research is the sun protection devices for translucent enclosing structures such as blinds. The goal of this research lies in examination of the historical experience and modern practice of using sun protection devices. The author conducts retrospective research of the evolution of blinds in order to determine the key stages in the development of structures that regulate the luminous flux. The historical discourse of the evolution of the system of blinds is based on the retrospective analysis of blinds according to the main characteristics, such as materials used, their location (indoors or building facades), and gear options. The author determines three main periods can in the evolution of blinds. The first period started in 1841, when John Hampton patented dentition blinds and lasted until 1936 (the design and materials used did not change throughout this period).The second period lasts from 1936 to 1960, and marks the emergence of the facade constructs "sun-cutter blinds", as well as the use of aluminum for the production of fins. The third period covers 1960s-1970s, is characterized by progressive automatic control, implementation of PVC, and improvement of energy efficiency of blinds using photovoltaic fins.
