A window blind is for covering and protection of windows. There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind. Window blinds can be either manual or electrical. The term window blinds can also be used to describe window coverings generically—in this context window blinds include almost every type of window covering, i.e. roller blinds, combi blinds, vertical blinds, venetian blinds & roman blinds.
