VENETIAN BLINDS or INTERIOR BLINDS are classic sun protection, and their advantage lies in the decisive possibility of regulating light. The slats of venetian blinds can be opened and closed stepwise, thus controlling the amount of light in a room. On one hand, venetian blinds equip and beautify a space, and on the other hand, they satisfy needs, demands, and desires such as light regulation, privacy, and prevention of heat and sunlight entry.
