Abstract

Glass lite retention systems and related methods are described herein. The glass lite retention systems and methods of resisting water penetration through the junctions between the glass lites and the openings in the fenestration panels when the fenestration panels are subjected to extreme weather events.

First claim

The invention claimed is:

1. A glass lite retention system comprising:
a fenestration panel comprising an opening formed through the fenestration panel, the opening extending through the fenestration panel from a first major side of the fenestration panel to a second major side of the fenestration panel, the opening comprising an opening perimeter defining a shape of the opening;
a glass lite positioned in the opening;
a first frame positioned on the first major side of the fenestration panel, the first frame comprising one or more first frame members defining a shape of the first frame, wherein the first frame is positioned over a junction between a lite perimeter of the glass lite and the opening perimeter on the first major side of the fenestration panel; and
a second frame positioned on the second major side of the fenestration panel, the second frame comprising one or more second frame members defining a shape of the second frame, wherein the second frame is positioned over the junction between the lite perimeter and the opening perimeter on the second major side of the fenestration panel;
wherein a first frame-panel junction between the first frame and the first major side of the fenestration panel comprises an airtight panel seal between the first frame and the first major side of the fenestration panel;
wherein a first frame-lite junction between the first frame and a first major surface of the glass lite comprises an airtight lite seal between the first frame and the first major surface of the glass lite; and
wherein a second frame-panel junction between the second frame and the second major side of the fenestration panel comprises a vent between the second frame and the second major side of the fenestration panel at a selected location along the second frame-panel junction, and wherein the vent is configured to pass liquid water through the second frame-panel junction.

2. The glass lite retention system according to claim 1 , wherein the vent is configured to pass liquid water through the second frame-panel junction under the force of gravity.

3. The glass lite retention system according to claim 1 , wherein the vent comprises a channel formed in the second frame, wherein the channel extends across the second frame-panel junction.

4. The glass lite retention system according to claim 1 , wherein the vent comprises a first vent of a plurality of vents between the second frame and the second major side of the fenestration panel, wherein each vent of the plurality of vents is positioned at a selected location along the second frame-panel junction and is configured to pass liquid water through the second frame-panel junction.

5. The glass lite retention system according to claim 1 , wherein the first frame is attached to the second frame through the junction between the lite perimeter and the opening perimeter.

6. The glass lite retention system according to claim 1 , wherein the second frame-panel junction comprises a panel seal between the second frame and the second major side of the fenestration panel, wherein the vent comprises a gap in the panel seal of the second frame-panel junction.

7. The glass lite according to claim 6 , wherein the panel seal between the second frame and the second major side of the fenestration panel comprises a gasket.

8. The glass lite according to claim 1 , further comprising a lite seal between the second frame and a second major surface of the glass lite.

9. The glass lite according to claim 8 , wherein the lite seal between the second frame and the second major surface of the glass lite comprises a continuous seal located inward from and extending continuously around the lite perimeter.

10. The glass lite retention system according to claim 1 , wherein the first frame-lite junction comprises a first lite seal located between the first frame and the first major surface of the glass lite, wherein the first lite seal extends continuously around a perimeter of the first frame; and
wherein the first frame-panel junction comprises a first panel seal located between the first frame and the first major side of the fenestration panel, wherein the first panel seal extends continuously around the perimeter of the first frame outside of the opening perimeter.

11. The glass lite retention system according to claim 10 , wherein the first lite seal comprises a first lite gasket located between the first frame and the first major surface of the glass lite; and wherein the first panel seal comprises a first panel gasket located between the first frame and the first major side of the fenestration panel.

12. The glass lite retention system according to claim 10 , wherein the first lite seal comprises a first lite gasket located between the first frame and the first major surface of the glass lite.

13. The glass lite retention system according to claim 10 , wherein the first lite seal comprises a first wet lite seal located between the first frame and the first major surface of the glass lite; and
wherein the first panel seal comprises a first wet panel seal located between the first frame and the first major side of the fenestration panel.

14. The glass lite retention system according to claim 10 , wherein the first lite seal comprises a first wet lite seal located between the first frame and the first major surface of the glass lite.

15. The glass lite retention system according to claim 10 , wherein the first frame-lite junction comprises a first auxiliary lite seal located between the first frame and the first major surface of the glass lite, wherein the first auxiliary lite seal extends continuously around a perimeter of the first frame.

16. The glass lite retention system according to claim 15 , wherein the first auxiliary lite seal is located inward of the first lite seal such that the first auxiliary lite seal is located between the first lite seal and a lite edge when moving around the perimeter of the first frame.

17. The glass lite retention system according to claim 10 , wherein the first frame-panel junction comprises a first auxiliary panel seal located between the first frame and the first major side of the fenestration panel, wherein the first auxiliary panel seal extends continuously around a perimeter of the first frame.

18. The glass lite retention system according to claim 17 , wherein the first auxiliary panel seal is located inward of the first panel seal such that the first auxiliary panel seal is located between the first panel seal and the opening perimeter when moving around the perimeter of the first frame.

19. A method of retaining a glass lite in an opening of a fenestration panel utilizing the glass lite retention system of claim 1 , the method comprising:
locating a glass lite in an opening of a fenestration panel;
positioning a first frame on a first major side of the fenestration panel, wherein an inner portion of the first frame is positioned over a portion of a first major surface of the glass lite;
positioning a second frame on a second major side of the fenestration panel, wherein an inner portion of the second frame is positioned over a portion of a second major surface of the glass lite such that the glass lite is located between the first frame member and the second frame member;
forming an airtight lite seal between the first frame and the first major surface of the glass lite; forming an airtight panel seal between the first frame and the first major side of the fenestration panel; and
providing a vent at a selected location in a second frame-panel junction between the se
