Building aperture cover, such as a window or door, comprising flexible gasket with sealed cavity

A method of retrofitting a building aperture cover to comprise a vacuum insulated glass unit, wherein the method comprises the steps of:

• removing an insulated glass unit of a building aperture cover from an existing frame arrangement,
• providing a vacuum insulated glass unit comprising an evacuated gap placed between a first and a second glass sheet, and wherein a plurality of support structures are arranged in the evacuated gap,
• arranging the vacuum insulated glass unit in said existing frame arrangement, and
• placing elongated flexible sealing gaskets between an outer major surface of the vacuum insulated glass unit and a frame part, so that the elongated flexible sealing gaskets extend substantially parallel to an edge of the vacuum insulated glass unit,
• wherein the elongated flexible sealing gaskets comprise
• a first flexible sealing gasket comprising an interior, sealed cavity configured to comprise a pressurized fluid, where the first flexible sealing gasket is arranged between a first frame part of the frame arrangement and an outer major surface of the vacuum insulated glass unit, and
• a second flexible sealing gasket comprising an interior, sealed cavity configured to comprise a pressurized fluid, where the second flexible sealing gasket is arranged between a second frame part of the frame arrangement and another opposite outer major surface of the vacuum insulated glass unit.

A building aperture cover, comprising:

• a frame arrangement;
• a vacuum insulated glass unit arranged in the frame arrangement and comprising an evacuated gap placed between a first and a second glass sheet, and a plurality of support structures are arranged in the evacuated gap;
• elongated flexible sealing gaskets arranged between an outer major surface of the vacuum insulated glass unit and a frame part of the frame arrangement;
• wherein the elongated flexible sealing gaskets are arranged to extend substantially parallel to an edge of the vacuum insulated glass unit,
• wherein the elongated flexible sealing gaskets comprise
• a first flexible sealing gasket comprising an interior, sealed cavity comprising a pressurized fluid, where the first flexible sealing gasket is arranged between a first frame part of the frame arrangement and an outer major surface of the vacuum insulated glass unit, and
• a second flexible sealing gasket comprising an interior, sealed cavity comprising a pressurized fluid, where the second flexible sealing gasket is arranged between a second frame part of the frame arrangement and another opposite outer major surface of the vacuum insulated glass unit, wherein the pressures in the cavities are higher than the ambient air pressure.
