Horizontal blinds are window coverings made of long, flat slats that can be adjusted to control light and privacy. These slats are typically made from materials like aluminum, wood, or vinyl and are arranged horizontally. Users can tilt the slats to allow light in while maintaining privacy or completely raise the blinds to open up the window. The design of horizontal blinds makes them easy to operate, often using a pull cord or a wand. They are popular in homes and offices due to their versatility and ability to fit various window sizes. Additionally, they come in a range of colors and styles to match different decor.
