What is a Window Blind?
A window or door blind is a covering for a window or door, usually attached to the interior side of a window. It simply refers to some device to hide from sight (thus "blinding" the viewer) or to reduce sunlight (and therefore heat, i.e. during the summer). There are several kinds of blinds, including:
Slat blinds, which consist of many vertical, flat slats, usually of metal or vinyl, connected with string in a way that they can be rotated to allow light to pass between the slats, rotated up to about 170 degrees to hide the light, or pulled up so that the entire window is clear (so special version pulling up diagonally or even down — mostly motorised or with hand winder). The blinds can be tilted by rotating a small knob that is attached to the strings, twisting a long wand or by pulling a cord; the raising and lowering of the blinds is achieved by pulling a different string. However, there also exists version with a winding mechanisms that combine both functions into one winding rod and can mostly also be used for motorisation. Such blinds include:
Venetian blinds -
basic slatted blind made of metal or plastic; wooden slats are sometimes used but these are usually referred to as wood blinds or bamboo blinds. Venetian blinds were introduced around 1770, possibly in Venice, Italy. Slat width can be between 50-120 mm, however most common are 50 mm).
Miniblinds -
Venetian blinds with very narrow slats (usually 19 or 24 mm wide).
Vertical blinds -
or track blinds, consisting of slats of stiffened fabric, plastic, or metal hanging by one end from a track; like the horizontal versions, the slats can be rotated 90 degrees to allow light to pass through or to fold up on one side of a door or window. |
