Made of semitransparent architectural glass and aluminum, the Siparium system of sliding panels adds an elegant, graceful element to any residential or contract space.  Customizable to up to 60-by-10 feet, the panels slide on ceiling- or wall-mounted tracks, with no need for floor tracks; as many as four rails can be combined.  Stiles and rails come in a satin aluminum finish; wrapped in cherry, walnut, oak, or wengé veneers; or stained in various colors.  Glass colors include more than 20 choices.
