    摘要: The present disclosure relates to a building aperture cover (1) such as a window or a door. The building aperture cover comprises a frame arrangement (2) and a vacuum insulated glass unit (3), wherein the vacuum insulated glass unit (3) comprises an evacuated gap (4) placed between a first and a second glass sheet (3a, 3b), and wherein a plurality of support structures (5) are arranged in the evacuated gap (4). The vacuum insulated glass unit (3) is arranged in the frame arrangement (2, 6). The building aperture cover (1) comprises one or more elongated flexible sealing gaskets (21, 22) arranged between an outer major surface (S1, S2) of the vacuum insulated glass unit (3) and a frame part (13a, 13c, 23a, 23c) of the frame arrangement (2, 6). The one or more elongated flexible sealing gaskets (21, 22) is arranged to extend substantially parallel to an edge (7, 50a-50d) of the vacuum insulated glass unit (3). One or more of the one or more elongated flexible sealing gaskets (21, 22) comprises an interior, sealed cavity (21a, 22a) configured to comprise a pressurized fluid.
