Disclosed is a double-canvas insulated door that comprises: a frame (1) with pairs of vertical guides (21, 22) for simultaneously guiding two canvases (31, 32) that can, simultaneously, be moved vertically towards an open position or a closed position, an intermediate air-filled cavity (5) being defined between the canvases; and a motor element (4) that actuates drums (41, 42) for rolling and unrolling the canvases (31, 32). The double canvas insulated door is characterised in that it comprises an air ioniser (6) in the intermediate cavity (5). |
