Abstract

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 ( 3 a, 3 b ), 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 (S 1 , S 2 ) of the vacuum insulated glass unit ( 3 ) and a frame part ( 13 a, 13 c, 23 a, 23 c ) 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, 50 a - 50 d ) 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 ( 21 a, 22 a ) configured to comprise a pressurized fluid.

First claim

The invention claimed is:

1. 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 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 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.

2. The building aperture cover according to claim 1 , wherein the edges of the vacuum insulated glass unit are configured to deflect when subjected to a temperature difference between the first and the second glass sheet, and wherein said flexible sealing gasket is configured to follow the movement of the vacuum insulated glass unit when the edges of the vacuum insulated glass unit deflects due to said temperature difference.

3. The building aperture cover according to claim 1 , wherein said fluid in the cavity is a gas.

4. The building aperture cover according to claim 1 , wherein the flexible sealing gasket abuts an outer surface of the vacuum insulated glass unit.

5. The building aperture cover according to claim 1 , wherein the cavities of the first and second said flexible sealing gaskets are configured to be in fluid communication with each other.

6. The building aperture cover according to claim 1 , wherein the pressure in the cavity is higher than the ambient air pressure.

7. The building aperture cover according to claim 1 , wherein the wall material of the one or more flexible sealing gaskets comprises an elastomer.

8. The building aperture cover according to claim 1 , wherein an adhesive is arranged to fixate the vacuum insulated glass unit to the frame arrangement and wherein the flexible sealing gasket is arranged at the same side of the vacuum insulated glass unit as said adhesive.

9. The building aperture cover according to claim 1 , wherein the flexible sealing gasket comprises an inlet to the cavity and is configured to be inflated by means of a pumping arrangement arranged to be in fluid communication with the inlet.

10. The building aperture cover according to claim 1 , wherein two or more edges of the vacuum insulated glass unit has a length that is at least one 0.8 meter.

11. The building aperture cover according to claim 1 , wherein the pressure in the cavity at a temperature of 20° C. is between 0.5% and 50% larger than the ambient atmospheric pressure.

12. The building aperture cover according to claim 1 , wherein the evacuated gap has a thickness/width below 1 mm wherein a Uglazing value of the vacuum insulated glass unit is below 0.9 W/(m{circumflex over ( )}2 k), wherein an edge seal seals the evacuated gap between the first and second glass sheets, and wherein said edge seal is or comprises a fused edge seal.

13. The building aperture cover according to claim 1 , wherein said one or more elongated flexible sealing gaskets is/are configured to displace with a displacement distance of at least the thickness of one of said glass sheets of the vacuum insulated glass unit due to a deflection of the vacuum insulated glass unit caused by a temperature difference between the first and the second glass sheet, and wherein said temperature difference is at least 30° C.

14. The building aperture cover according to claim 1 , wherein said one or more elongated flexible sealing gaskets is/are configured to displace with a displacement distance corresponding to at least 20% of the thickness of the vacuum insulated glass unit due to a deflection of the vacuum insulated glass unit caused by a temperature difference between the first and the second glass sheet and wherein said temperature difference is at least 30° C.

15. 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
