The are many Blinds available today, this article looks at some of the more popular. In the coming weeks Sensational Blinds and Flooring will add more blinds and discuss the merits of Motorised Blinds which are becoming increasingly popular.
Persian, or slat
The most common window blinds are slat blinds, which consist of many horizontal slats, usually of aluminium (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. Vertical blinds consist 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. Vertical blinds are very good at controlling how much natural or exterior light comes into a room, due to the ability of the slats to close tightly.
A Venetian blind (or venetian blind) has horizontal slats, one above another. Venetian blinds are basic slatted blinds made of metal or plastic; wooden slats are sometimes used but in the US these are now usually referred to as wood blinds or bamboo blinds. They are suspended by strips of cloth called tapes, or by cords, by which all slats in unison can be rotated through nearly 180 degrees. The slats can be rotated such that they overlap with one side facing inward and then in the opposite direction such that they overlap with the other side facing inward. Between those extremes, various degrees of separation may be effected between the slats by varying the rotation. There are also lift cords passing through slots in each slat. When these cords are pulled, the bottom of the blind moves upward causing the lowest slats to press the underside of the next highest slat as the blind is raised. A modern variation of the lift cords combines them with the rotational cords in slots on the two edges of each slat. This avoids the slots otherwise required to allow a slat to rotate despite a lift cord passing through it, thus decreasing the amount of light passing through a closed blind. Slat width can be between 16–120 mm, with 25 mm being a common width.
Unlike horizontal blinds, vertical blinds are less likely to be damaged in strong winds and to hold dirt, but are more likely to break down. Generally they require less muscle strength, and are faster to operate.
Stationary vertical blinds are hung in the doorways of some homes and businesses which generally leave the door open. Movement of the blind may signal a change in air flow, or someone entering the doorway. More commonly however, these vertical blinds are made of thick plastic. In the cold rooms of food businesses, this slows the heat leakage into the cold room. In warmer climates, vertical blinds discourage flies and some other insects from entering the building.
Other variety of window blinds include mini blinds (Venetian blinds with very narrow slats, usually 1 in (25 mm) wide), micro blinds (usually in (12 mm) wide), Louver blind, Jalousie, brise soleil, Holland blind, Pleated blind, Roman blind and the ever popular Roller blind
