The present invention provides ultrathin polycarbonate panels for use in security isolation cells to provide a transparent and secure barrier between a prisoner and a guard, where the barrier passes flammability test ASTM E-84 Class A. The panel comprises at least one polycarbonate sheet having a thickness between 0.25 mm and 1 mm. Panels may optionally include a metal support and a frame, and the frame may overbite (edge bite) a portion of the polycarbonate panel, and all points of the polycarbonate panel may be located within four frame widths of the frame. La présente invention concerne des panneaux de polycarbonate ultraminces destinés à être utilisés dans des cellules d'isolement de sécurité pour fournir une barrière transparente et sûre entre un prisonnier et un garde, où la barrière passe l'essai d'inflammabilité ASTM E -84 Class A. Le panneau comprend au moins une feuille de polycarbonate ayant une épaisseur comprise entre 0,25 mm et 1 mm. Les panneaux peuvent éventuellement comprendre un support métallique et un cadre, et le cadre peut dépasser (morsure de bord) une partie du panneau de polycarbonate, et tous les points du panneau de polycarbonate peuvent être situés à l'intérieur de quatre largeurs de cadre du cadre.
