Many window blinds are made with slats of fabric, metal, plastic, or wood that are adjusted by being rotated from an open position (in which the slats do not overlap) to a closed position (in which they do). Metal window blinds are often used outside of a home or business to protect against theft, temperature, onlookers, glare, bad weather, or fire (in fire-prone areas); often, these blinds are machine-operated, rather than hand-operated.
Some types of blinds, such as Holland blinds and woven-wood blinds, have small spaces between the slats. Others, such as pleated shades, have no spaces, because the slats are sewn inside fabric. Window blinds reduce the heat from sunlight. Ancient Egyptian pharaohs had blinds made of reeds. The most inexpensive blinds in the 19th century were home-made roller blinds, made of cloth.
The term window blinds is also sometimes used, somewhat inaccurately, to describe window coverings generically—in this context window blinds include almost every type of window covering, including both curtains and blinds for homes and commercial premises, such as bars/pubs, offices, and shops, e.g., Plantation Shutters/Jigsaw Shutters, Roman blinds, roller blinds, and of course, vertical and horizontal blinds.
