Young Brunette Girl In The Glass Room With Blinds

In the late 19th and early 20th centuries, Venetian blinds were widely adopted in office buildings to regulate light and air. A large modern complex in the US that adopted Venetian blinds was Rockefeller Center’s RCA Building (better known as the Radio City building) in New York City, completed in the 1930s. One of the largest orders for Venetian blinds ever placed was to the Burlington Venetian Blind Co., of Burlington, Vt., which supplied blinds for the windows of the Empire State Building in New York City.
• Vertical‎
Unlike horizontal blinds, vertical blinds are less likely to be damaged in strong winds and to hold dirt, but are more likely to break down. Generally they require less muscle strength, and are faster to operate.
Stationary vertical blinds are hung in the doorways of some homes and businesses which generally leave the door open. Movement of the blind may signal a change in air flow, or someone entering the doorway. More commonly however, these vertical blinds are made of thick plastic. In the cold rooms of food businesses, this slows the heat leakage into the cold room. In warmer climates, vertical blinds discourage flies and some other insects from entering the building.
