Windows Blinds

Mrtina said :There are two overall types of windows blinds are ready-made blinds and made to measure. Made-to-measure blinds are made to fit a given or measured window size. Ready-made blinds are manufactured in set sizes that can be cut down to fit any window.

These windowss blinds can be classified broadly into six different categories: roller blinds (which do not have slats but consist of a single piece of material), Roman blinds, pleated blinds, Venetian blinds, vertical blinds.

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.

TZ horizontal blinds use a thin woven corded "ladder" system to suspend the slats and enable them to be closed or opened via a rotating drum to which each upper end of the woven ladder is wrapped and attached. A lift cord allows the blind to be pulled up and stack tightly to top of the window when desired.

Vertical blinds use a generally wider slat and one can pull a cord to stack the slats together, to one side, or to separate them in the centre and stack them on each end. The slats can be rotated via a rotating shaft in the upper head rail housing, which runs through independent geared carriers that convert the twisting of a tilt rail to a rotation of each individual slat in synchrony. 

In Britain, awnings and window shutters are often categorized under blinds, which are so named because they limit observation and thus “blind” the observer to the view. The main types are slat blinds which can be opened in two ways, and solid blinds, which can only be raised or lowered, and are sometimes called shades.

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.

Window blinds can be manually drawn using a cord, or automated through motorization. Controls for motorized blinds can be from a wall switch or keypad, remote control, or computer, eliminating the need for cords and allowing control of otherwise inaccessible windows.
