Blinds Facts
November 12, 2008admin No Comments »
A window blind is a window covering composed of long strips of fabric or rigid material. Examples include shutters, Venetian blinds, roller shades and curtain-like track blinds. In Britain awnings are also considered blinds. A blind limits observation and thus “blinds” the observer to the view. The main types are slat blinds which can be opened in two ways and solid blinds.
Slat blinds have long strips called slats. These can be rotated to open the blind while it is still covering the window. In track blinds the slats hang vertically from one end. In Venetian blinds and mini blinds the slats are suspended horizontally on cords. A slat blind can also be opened so it is no longer covering the window.
Solid blinds can only be raised or lowered and are often called shades. In some such as Holland blinds and woven-wood blinds there are small spaces between the slats. In others such as pleated shades there are 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 1800’s were home-made roller shades, made of cloth.
Window blinds can be manually drawn or automated through motorization, controlled from a wall switch or keypad, remote control, or a personal computer, thus eliminating the hazard of dangling cords.
