Abstract

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a fenestration unit. In certain instances, the fenestration units, and methods of re-glazing the fenestration units, described herein may be re-glazed from an interior space.

First claim

What is claimed is:

1. A fenestration unit comprising:
a glazing unit having a peripheral edge region, a first side and a second side;
a frame defining a head, a sill, a first jamb and a second jamb, the frame having a frame profile defining a first coupling element and an engagement face to which the first side of the glazing unit is releasably coupled;
a glazing stop including a first coupling element and a first engagement face, wherein the first coupling element includes an opening extending along an axis, wherein the first coupling element of the glazing stop is releasably coupled to the first coupling element of the frame and when releasable coupled to the first coupling element of the frame, a majority of the first coupling element of the glazing stop is parallel with the axis of the opening of the glazing stop, wherein the first engagement face of the glazing stop is releasably coupled to the second side of the glazing unit;
a cover distinct from and removably coupled to the glazing stop;
a first sealing member disposed between the first side of the glazing unit and the engagement face of the frame; and
a second sealing member disposed between the second side of the glazing unit and the first engagement face of the glazing stop.

2. The fenestration unit of claim 1 , wherein the glazing stop includes a second coupling element and the cover is coupled to the second coupling element of the glazing stop.

3. The fenestration unit of claim 2 , further including a joining member configured to couple the glazing stop to the cover.

4. The fenestration unit of claim 3 , wherein the joining member is configured to frictionally engage the glazing stop to the cover and maintain coupling between the glazing stop to the cover.

5. The fenestration unit of claim 4 , wherein the joining member includes a first barbed portion configured to engage a channel in the glazing stop and a second barbed portion configured to engage a channel in the cover.

6. The fenestration unit of claim 2 , further including a fastener configured to engage the glazing stop with the frame.

7. The fenestration unit of claim 1 , wherein the first sealing member is adhesively coupled to the engagement surface of the frame and non-adhesively coupled to the first side of the glazing unit.

8. The fenestration unit of claim 7 , wherein the second sealing member is adhesively coupled to the second side of the glazing unit and the first engagement face of the glazing stop.

9. The fenestration unit of claim 8 , wherein the first sealing member and the second sealing member comprise foam and are at least one of air-permeable and moisture-blocking.

10. The fenestration unit of claim 9 , further including a third sealing member disposed between the frame and the glazing stop.

11. The fenestration unit of claim 10 , wherein the third sealing member is adhesively coupled to the glazing stop and non-adhesively coupled to the frame.

12. The fenestration unit of claim 1 , wherein the frame defines one or more weep holes configured to guide fluid within the fenestration unit from the fenestration unit to the exterior space.

13. A fenestration unit defining a boundary between an interior space and an exterior space, the fenestration unit comprising:
a glazing unit having a peripheral edge region, a first side and a second side;
a frame defining a head, a sill, a first jamb and a second jamb, the frame having a frame profile defining a first coupling element and an engagement face to which the first side of the glazing unit is releasably coupled, wherein the first coupling element of the frame includes an opening extending along a lateral axis;
a glazing stop including a first coupling element and a first engagement face, wherein the first coupling element of the glazing stop is releasably coupled to the first coupling element of the frame, wherein the first engagement face of the glazing stop is releasably coupled to the second side of the glazing unit and removable from the interior space;
a cover distinct from and removably coupled to the glazing stop;
a first sealing member disposed between the first side of the glazing unit and the engagement face of the frame; and
a second sealing member disposed between the second side of the glazing unit and the first engagement face of the glazing stop and removable from the interior space.

14. The fenestration unit of claim 13 , further comprising a fastener configured to couple the glazing stop with the frame, wherein the cover, the fastener, the second sealing member, the glazing stop and the glazing unit are removable from the interior space.

15. A method of re-glazing a fenestration unit defining a boundary between an interior space and an exterior space, the method comprising:
accessing a glazing unit arranged within a frame by removing a cover coupled to the frame, the glazing unit having a peripheral edge region, a first side and a second side and the frame defining a head, a sill, a first jamb and a second jamb, the frame having a frame profile defining a first coupling element and an engagement face to which the first side of the glazing unit is releasably coupled and a first sealing member disposed between the first side of the glazing unit and the engagement face of the frame, wherein the first coupling element of the frame includes an opening extending along a lateral axis;
removing a glazing stop from the interior space, the glazing stop including a first coupling element and a first engagement face, wherein the first coupling element of the glazing stop is releasably coupled to the first coupling element of the frame, wherein the first engagement face of the glazing stop is releasably coupled to the second side of the glazing unit; and
removing a second sealing member from the interior space, the second sealing member being disposed between the second side of the glazing unit and the first engagement face of the glazing stop and from the interior space.

16. The method of claim 15 , further comprising a fastener configured to couple the glazing stop to the frame, wherein the cover, the fastener, the second sealing member, the glazing stop, and the glazing unit are removable from the interior space.
