NanaWall's new HSW50 individual panel sliding system makes traditional walls virtually unnecessary. The thermally broken aluminum-framed system lets architects create walls of glass with no visual track on the floor and, according to the manufacturer, offers the same security and wind load capabilities as a track-based system. The panels can be installed anywhere a regular wall would stand and can even be outfitted with swinging doors. NanaWall Systems, 800.873.5673;
