Made with slats that rotate from open to closed positions allowing you to precisely control privacy and light levels. Blinds can also be pulled up so they stack at the top of the window allowing unobstructed views and even more light from the outside.
Vertical blinds operate in much the same fashion. However, as the name implies, the slats are orientated vertically and they stack to one side or the other. Most often, these are used with doors or very wide window openings.
These treatments are quite easy to maintain as they are not usually made of fabric so a quick wipe with a damp cloth is enough.
Blinds do require the most complex operating hardware usually consisting of a cord or endless loop system for pulling the stack up and down, and a separate wand control for slat rotation control.
