Abstract

A window wall system includes a first glazing unit arranged adjacent a first vertical wall substrate, a second glazing unit arranged adjacent a second vertical wall substrate opposite the first vertical wall substrate, one or more third glazing units extending laterally between the first and second glazing units, and a jamb filler operatively coupled to the second glazing unit and interposing the second glazing unit and the second vertical wall substrate.

First claim

What is claimed is:

1 . A window wall system, comprising:
a first glazing unit arranged adjacent a first vertical wall substrate; a second glazing unit arranged adjacent a second vertical wall substrate opposite the first vertical wall substrate; one or more third glazing units extending laterally between the first and second glazing units; and a jamb filler operatively coupled to the second glazing unit and interposing the second glazing unit and the second vertical wall substrate.

2 . The window wall system of claim 1 , wherein the jamb filler is operatively coupled to the second glazing unit via one or more mating features and without mechanical fasteners.

3 . The window wall system of claim 1 , further comprising one or more backer rods interposing the jamb filler and the second vertical wall substrate.

4 . The window wall system of claim 1 , wherein the one or more third glazing units include:
a left glazing unit that includes a right vertical mullion half; and a right glazing unit that includes a left vertical mullion half, wherein the left and right glazing units are secured together by mating the right and left vertical mullion halves.

5 . The window wall system of claim 4 , wherein the right and left vertical mullion halves are mated by laterally shifting the right glazing unit toward the left glazing unit until the left vertical mullion half locates and mates to the right vertical mullion half.

6 . The window wall system of claim 5 , wherein the right and left vertical mullion halves are mated via a snap-in engagement.

7 . The window wall system of claim 1 , wherein the second glazing unit comprises a vertical jamb member and one or more panels received by and extending from the vertical jamb member, and wherein the jamb filler lacks a panel.

8 . A window wall system, comprising:
a glazing unit arranged adjacent a vertical wall substrate to define a gap therebetween, the glazing unit comprising a vertical jamb member and one or more panels received by and extending from the vertical jamb member; and a jamb filler operatively coupled to the glazing unit and positioned within the gap, wherein the jamb filler lacks a panel.

9 . The window wall system of claim 8 , wherein the jamb filler is operatively coupled to the glazing unit without mechanical fasteners.

10 . The window wall system of claim 8 , wherein the jamb filler provides a first hook extending in a first horizontal direction and the vertical jamb member provides a second hook extending in a second horizontal direction opposite the first horizontal direction.

11 . The window wall system of claim 8 , wherein a second gap of about ½ inch is defined between the jamb filler and the vertical wall substrate.

12 . The window wall system of claim 11 , further comprising one or more backer rods positioned in the second gap.

13 . The window wall system of claim 8 , wherein the glazing unit is a first glazing unit and the window wall system further comprises a plurality of additional glazing units extending from the first glazing unit, the plurality of additional glazing units comprising:
a left glazing unit that includes a right vertical mullion half; and a right glazing unit that includes a left vertical mullion half, wherein the left and right glazing units are secured together by mating the right and left vertical mullion halves.

14 . The window wall system of claim 13 , wherein the right and left vertical mullion halves are mated via a snap-in engagement.

15 . A window wall system, comprising:
a glazing unit arranged adjacent a vertical wall substrate to define a first gap therebetween; and a jamb filler operatively coupled to the glazing unit and positioned within the first gap to define a second gap between the jamb filler and the vertical wall substrate, wherein the second gap is about ½ inch.

16 . The window wall system of claim 15 , wherein the jamb filler is operatively coupled to the glazing unit without mechanical fasteners.

17 . The window wall system of claim 15 , wherein the jamb filler provides a first hook extending in a first horizontal direction and the glazing provides a second hook extending in a second horizontal direction opposite the first horizontal direction.

18 . The window wall system of claim 15 , further comprising one or more backer rods positioned in the second gap.

19 . The window wall system of claim 15 , wherein the glazing unit is a first glazing unit and the window wall system further comprises a plurality of additional glazing units extending from the first glazing unit, the plurality of additional glazing units comprising:
a left glazing unit that includes a right vertical mullion half; and a right glazing unit that includes a left vertical mullion half, wherein the left and right glazing units are secured together by mating the right and left vertical mullion halves.

20 . The window wall system of claim 19 , wherein the right and left vertical mullion halves are mated via a snap-in engagement.
