Blinds and shades had long been the preferred mode of covering windows in offices and commercial establishments because it served a purpose, which wasn't a necessity on the home front. Most commercial buildings are walled in glass or have large glass areas that might be opened periodically only for the purpose of cleaning and not for ventilation. But the home windows are usually opened or closed as needed for illuminating with sunlight and more so for the ventilation. Lately, home window designs are following commercial styles and most often come in the fixed or sliding type, because with climate controlled interiors it does not require you to open your windows for ventilation.
