A high performance light transmissive glazing panel system is provided such as for overhead roof constructions which has a wind load resistance on the order of 330 psf. The glazing panels are supported on a framework of purlins and rafters and include upstanding seam flanges for connecting adjacent panels together with a batten joining connector. Retention clips are secured to the purlins with each having a central web extending between the seam flanges and elongated top flanges which abut the tops of the seam flanges over a distance that is equal to or greater than the transverse width of the purlin for improved holding power. The preferred clip is an integral extrusion and can take on a variety of forms in accordance with the invention. In each form, the clip top flange extends continuously from one side of the web to the other so as to be resistant to being bent upward on either side of the web. The clip can be extruded with thickened portions to increase its moment of inertia and resistance to bending for improved holding power and rigidity of the glazing panel system. In addition, the base of the clip can be integral with the supporting structure therebelow to reduce the need for distinct support members of the panel supporting framework.

[ What is claimed is:] [1.] A glazing panel system for use with rafters and purlins and having light transmission to withstand forces of approximately 50 psf or 100 mph wind speeds, said glazing system comprising:a plurality of glazing panels being for being supported by a framework of rafters and purlins each of the panels having top and bottom sheets thereof;an upstanding seam flange at opposite ends of the panels extending upwardly from the top sheets of the panels and having a top side thereon, the upstanding seam flanges having exterior faces that are disposed parallel and adjacent to one another;joining connectors fitted over the tops of adjacent seams and connecting the adjacent, upstanding seam flanges together and covering a seam formed between adjacent, glazing panels;at least one retention clip disposed between adjacent, upstanding seams and having a base for being secured to the purlins to secure the glazing panels to the purlins;a central web on the retention clip positioned between adjacent seam flanges at the location of the purlin; anda top flange on the retention clip abutting the top sides of each of said adjacent seam flanges over a distance about equal to or greater than the length of the base to retain the glazing panels against said forces, the central web having side bearing surfaces that are substantially flat and extend continuously between the top flange and base of the clip with the bearing surfaces having a predetermined height sized to substantially match that of the exterior faces of the seam flanges between the top sides of the seam flanges and the bottom sheet of the panels to allow the exterior faces to bear flush against the web bearing surfaces continuously therealong between the top flange and base of the clip.
