Abstract

The present disclosure relates to an aperture covering, such as a building aperture covering. The aperture covering comprises a VIG unit 3 and a frame. The frame (2) comprises elongated fixation profiles (6) each of which are fixed to and arranged parallel to an elongated structural frame member (8). The fixation profile (6) comprises a fixation wall (6a) which extends opposite to an exterior major surface (S1) of the vacuum insulated glass unit (3) and is fixed to the exterior major surface (S1) of the vacuum insulated glass unit (3) by means of a bonding seal (9). The fixation profile (6) comprises a connection member (6b) extending from the fixation wall (6a), wherein the connection member (6b) is fixed to the elongated, structural frame member (8). The elongated structural member (8) faces the opposite interior major surface (S2) of the vacuum insulated glass unit (3) placed opposite to the exterior major surface (S1) of the vacuum insulated glass unit.

First claim

The invention claimed is:

1. An aperture covering, wherein said aperture covering comprises:
a vacuum insulated glass unit comprising a first glass sheet and a second glass sheet, wherein an evacuated gap is placed between the first and second glass sheets, and wherein a plurality of support structures are distributed in the evacuated gap, and wherein a rigid, fused edge seal seals the evacuated gap,
a frame enclosing a frame opening,
elongated fixation profiles each of which are fixed to and arranged parallel to an elongated structural frame member,
wherein each elongated fixation profile comprises a fixation wall which extends opposite to an exterior major surface of the vacuum insulated glass unit and is fixed to the exterior major surface of the vacuum insulated glass unit by means of a bonding seal,
wherein the fixation profile comprises a connection member extending from said fixation wall wherein the connection member is fixed to the elongated, structural frame member,
wherein the elongated structural member faces the opposite interior major surface of the vacuum insulated glass unit placed opposite to the exterior major surface of the vacuum insulated glass unit,
wherein the evacuated gap overlaps the elongated structural member, and
wherein the edges of the vacuum insulated glass unit extends into a receiving slot provided by the frame, and wherein the receiving slot has a width which is larger than 1.5 times the thickness of the part of the vacuum insulated glass unit which extends into the receiving slot.

2. An aperture covering according to claim 1 , wherein the bonding seal is a flexible, elongated adhesive sealing stripe bonding to the exterior major surface of the vacuum insulated glass unit and to a surface of the fixation wall facing the exterior major surface, wherein said bonding seal includes or is a structural adhesive.

3. An aperture covering according to claim 2 , wherein the structural adhesive is a silicon adhesive, a silane-terminated polyurethane adhesive or a Modified-Silyl Polymer adhesive, wherein at least said fixation wall of the fixation profile comprises a metal surface, and wherein said bonding seal is attached to said metal surface.

4. An aperture covering according to claim 3 , wherein said fixation profile is a metal profile.

5. An aperture covering according to claim 1 , wherein the bonding seal has a thickness above 4 mm, wherein the thickness is determined in a direction perpendicular to the exterior major surface at a temperature difference between the glass sheets of the VIG unit of substantially 0° C.

6. An aperture covering according to claim 1 , wherein said bonding seal is arranged to bond to the exterior major surface so that the bonding seal material is terminated before and does not extend to the edge surface of the vacuum insulated glass unit.

7. An aperture covering according to claim 1 , wherein the bonding seal is located to partly or fully lap over an edge seal of the vacuum insulated glass unit.

8. An aperture covering according to claim 1 , wherein the evacuated gap overlaps the elongated structural member by between 15 mm and 100 mm, where the distance is determined parallel to a plane defined by an outer major surface of the vacuum insulated glass unit and is determined from the inner surface of the edge seal facing the evacuated gap, and to a line of sight through the vacuum insulated glass unit and the frame opening.

9. An aperture covering according to claim 1 , wherein the fixation wall and/or the connection member of the fixation profile is a substantially solid, single walled construction.

10. An aperture covering according to claim 1 , wherein the elongated structural member overlaps the opposite interior major surface of the vacuum insulated glass unit with a larger overlapping distance than the overlapping distance with which the fixation wall overlaps the exterior major surface.

11. An aperture covering according to claim 1 , wherein the elongated structural member overlaps the opposite interior major surface of the vacuum insulated glass unit with an overlapping distance, wherein said overlapping distance is at least 25 mm.

12. An aperture covering according to claim 1 , wherein the connection member and the fixation wall together substantially provides an angle bracket shape, when seen in a plane which extends perpendicular to the longitudinal direction of the fixation profile.

13. An aperture covering according to claim 1 , wherein the vacuum insulated glass unit overlaps at least 60% of the largest width of the elongated, structural frame member, wherein said width is measured in a direction parallel to a major surface of the VIG unit, and in a direction perpendicular to the longitudinal direction of the elongated, structural frame member.

14. An aperture covering according to claim 1 , wherein a gasket strip is arranged between the elongated structural member and the interior major surface, wherein the gasket strip has a height which is above 4 mm at a temperature difference between the two glass sheets of substantially 0° C., and wherein said height is measured in a direction substantially perpendicular to the interior major surface.

15. An aperture covering according to claim 1 , wherein the vacuum insulated glass unit is a laminated vacuum insulated glass unit comprising a lamination glass attached to the vacuum insulated glass unit by means of an interlayer, wherein said aperture covering is a window for covering an aperture in a building.

16. An aperture covering according to claim 1 , wherein said frame is a movable sash which is connected to a fixation frame by means of a displacement mechanism configured to allow the sash to move relative to the fixed frame, wherein said fixation frame comprises elongated fixation frame members, wherein the connection member of the fixation profile is configured to extend between the overlapped elongated structural member and an elongated fixation frame member, at least when the sash is in a closed position.

17. An aperture covering according to claim 1 , wherein the edge seal extends around the periphery of the vacuum insulated glass unit and seals the evacuated gap, and wherein said edge seal comprises a glass material or a metal solder edge seal material, wherein said bonding seal and/or said fixation profile is/are configured to allow edges of the vacuum insulated glass unit to describe an edge deflection curve between corners of the vacuum insulated glass unit due to a thermal deflection of the vacuum insulated glass unit, where the edge deflection curve is provided in a direction perpendicular to a plane defined by an outer major surface of the vacuum insulated glass unit when the temperature difference between the glass sheets of the vacuum insulated glass unit is substantially 0° C.

18. An aperture covering according to claim 1 , wherein a further adhesive material, is placed between the fixation wall and the exterior major surface, and wherein the further adhesive material is fixed to at least one of the fixation wall and the exterior major surface of the vacuum insulated glass unit.

19. An aperture covering according to claim 1 , wherein the receiving slot has a width which is no more than 4 times the thickness of the part of the vacuum insulated glass unit which extends into the receiving slot, wherein the receiving slot provides a space of at least 3 mm at one or both sides of the vacuum insulated glass unit, determined in a direction normal to the outer surfaces of the vacuum insulated glass unit at a temperature differe
