<p>The transparent panel (1) comprises a base (3) of transparent thermoplastic plastic sheet (4) with hollow chambers (8) enclosed in an outer frame (2). The plastic frame (2) is integrated with the base, seals the open ends of the hollow chambers and is made of a plastic with a lower melting point (m.pt) than that of the sheet (4). An Independent claim is made for manufacturing the transparent panel, in which hollow chamber plates (3) are cut to size, arranged next to each other with the open ends on opposite sides of the plate, heated to dry the chambers (8) and placed in a tool for molding the edge frame (2). The plate edges (9) are compressed during tool closure and a plastic with a lower m.pt. than the plate is injected to form the frame.</p> |
