Abstract
Abstract A louver having clear transparent C-shaped holding flanges for holding decorative panels. The transparent holding flange on each longitudinal edge of each louver in a vertical louver system is held vertical by a louver track system. The louvers are moveable from an overlapped closed position to an open position. Each louver has a main body portion of opaque material. The C-shaped holding flanges or edge portions include two transparent longitudinal edge portions, one on each longitudinal edge of the long louver. The transparent edge portion is equal in width to a transparent inwardly facing flange portion positioned over each longitudinal edge portion. The transparent edge portion and transparent inwardly facing portion are connected together and separated by a transparent mid portion of a width generally equal to the thickness of a decorative member. The transparent material allows the edges of an inserted piece of decorative material to be viewed through the transparent, inwardly facing portions.
