Abstract: A sun filter for a glass louver panel is disclosed which filters out the heat, glare and the ultraviolet rays which normally penetrate through the glass. The sun filter is formed of a resilient, plastic material such that it may be easily snapped over the existing louver panel without dismantling the panel from its support structure or in any way interfering with the normal operation of the louver panel. The filter has a resilient filter panel which bears against a face of the louver panel and frictional attaching legs which frictionally engage opposite edges of the louver panel to removably affix the sun filter to the panel.

Abstract: A security clip is disclosed for use in a louver panel which prevents removal of the louver panel from its mounting brackets. The security clip extends substantially around the entire periphery of the louver panel and is substantially contained between the louver panel and the mounting bracket. A tab extending from the security clip engages a notch in the mounting bracket such that removal of the louver panel is positively prevented even if the mounting bracket is deformed. The ends of the security clip are positively locked to prevent deformation of the security clip.
