Termination girts and related systems and methods
Termination girts, systems incorporating termination girts, and methods of using termination girts are disclosed. The termination girts are configured to abut adjacent building systems such as windows, doors, interconnected walls and the like with a clearance close to zero, which allows exterior cladding on a structure to be hung in a seamless, smooth design without added gaps or reveals. In some embodiments, the termination girts are used, either with other types of girts or exclusively, to produce a continuous horizontal or vertical rail system on the exterior of a structure to support cladding covering the structure and, optionally, insulation mounted on the exterior of the structure. The termination girts have a high mechanical strength, are easily manufactured, allow for water drainage and air circulation, can be mounted in both horizontal and vertical orientations, and are especially useful near the intersection of perpendicular surfaces.
1. A termination girt comprising:
a box girt having a body comprising a front wall, a back wall, a first side wall connecting the front wall and the back wall, and a second side wall extending from the front wall toward the back wall, wherein the back wall and the second side wall are separated by a longitudinal gap, wherein the front wall and the back wall comprise at least partially aligned holes; and
a flange that is coplanar with the back wall, wherein the flange extends from an edge of the second side wall away from the body of the box girt.
2. The termination girt of claim 1 , wherein the box girt is a rectangular box girt.
3. The termination girt of claim 1 , wherein the front wall and the back wall are substantially parallel to one another.
4. The termination girt of claim 1 , wherein the first side wall and the second side wall are substantially parallel to one another.
5. The termination girt of claim 1 , wherein the first side wall and the second side wall are substantially parallel to one another and substantially perpendicular to the front wall and the back wall.
6. The termination girt of claim 1 , wherein the back wall is shorter than the front wall.
7. The termination girt of claim 1 , wherein the longitudinal gap extends the entire length of the termination girt.
8. The termination girt of claim 1 further comprising holes within the front wall that extend into the first side wall.
9. The termination girt of claim 1 further comprising elongated holes within the back wall.
10. The termination girt of claim 1 , wherein the first side wall and the second side wall comprise at least partially aligned holes.
11. The termination girt of claim 1 , wherein the flange comprises a plurality of holes.
12. The termination girt of claim 11 , wherein the holes are elongated holes.
13. The termination girt of claim 1 , wherein a terminal edge of the flange is bent toward a center line of the girt body.
14. A system for cladding an exterior wall of a structure and insulating the structure wall, the system comprising:
plural girts fastened to the structure wall in spaced array;
thermally insulating material positionally maintained adjacent the structure wall by the plural girts; and
exterior cladding for the structure supported by the plural girts;
wherein at least one of the plural girts is the termination girt of claim 1 .
15. The system of claim 14 , wherein the plural girts are horizontal girts.
16. The system of claim 15 further comprising plural vertical girts in spaced vertical array disposed between the thermally insulating material and the plural horizontal girts.
17. The system of claim 16 , wherein at least one of the plural vertical girts is the termination girt of claim 1 .
18. The system of claim 14 , wherein the system provides a continuously insulated wall assembly such that only fasteners attaching the plural girts to the exterior wall penetrate the thermally insulating material.
19. A method of using a termination girt, comprising:
placing the termination girt of claim 1 with the back wall and the first side wall of the termination girt abutting substantially perpendicular surfaces; and
applying fasteners through holes of the flange and/or the back wall into one of the substantially perpendicular surfaces.
