Abstract: A channel clip which is configured to hold glass or plastic decorative panels in front of single or dual pane windows without affecting the existing window glass and while permitting a spaced and secure relationship between the decorative panel and the inner-most window pane in the proximity of which the decorative panel is installed. In a preferred embodiment herein, the channel clip of the present invention is a transparent, injection-molded polycarbonate device having three integrated structural members including a base member and a pair of panel retaining members. The retaining members are positioned preferably in perpendicular relationship to the base member and in spaced apart parallel relation to one another. A gap formed therebetween is adapted to receive the designer panel. The base member preferably is provided with a countersunk or tapered aperture which is designed to accommodate a wood screw to secure the channel clip into the underlying surface adjacent the window pane.

Abstract: A material for use as a core in panels or structural members includes a longitudinal and transverse axis which lie in a common plane. The material includes alternating first and second strips that are interconnected at spaced intervals along the longitudinal axis by lands lying in the common plane. Each of the first strips is formed to have portions lying to one side of the common plane and each of the second strips has portions lying to the other side of the common plane. The interconnected lands define webs extending along the transverse axis to provide inherent stiffness to the material.
