Weather barrier for a building penetration with a removable collar

1. A weather barrier for a building penetration, the building penetration comprising an opening in a wall of a building and a utility extending through the opening, the weather barrier comprising:

a sheet made from a precipitation and wind resistant material, the sheet comprising a utility receiving chamber surrounded by a planar, building engaging section, the utility receiving chamber comprising a sidewall that extends perpendicularly to a plane defined by the building engaging section and terminates at a remote end; and

a structural collar that is friction fit within the sidewall of the utility receiving chamber, the structural collar having a first end face, a second end face, and a constant outer circumference between the first end face and the second end face, the structural collar being movable along the sidewall upon application of a sliding force between a first position in which the first end face is immediately adjacent to the remote end of the utility receiving chamber and a second position in which the first end face extends past the remote end of the utility receiving chamber, the structural collar having an inner circumference that receives an outer circumference of the utility.

2. The weather barrier of claim 1 , wherein at least the utility receiving chamber is resilient.

3. The weather barrier of claim 1 , wherein the utility receiving chamber and the building engaging section are integrally formed.

4. The weather barrier of claim 1 , wherein the sidewall has a rectangular or a rounded cross-section.

5. The weather barrier of claim 1 , wherein the inner circumference of the structural collar comprises a seal surface that, in use, sealingly engages the outer circumference of the utility.

6. A weather barrier for a building penetration, the building penetration comprising an opening in a wall of a building and a utility extending through the opening, the weather barrier comprising:

a sheet made from a precipitation and wind resistant material, the sheet comprising a utility receiving chamber surrounded by a planar, building engaging section, the utility receiving chamber comprising a sidewall that extends perpendicularly to a plane defined by the building engaging section; and

a structural collar that is friction fit within the sidewall of the utility receiving chamber, the structural collar being movable along the sidewall upon application of a sliding force, the structural collar having an inner circumference that receives an outer circumference of the utility;

wherein the sidewall of the sheet or the structural collar comprises a closed end that is spaced from the plane of the building engaging section of the sheet.

7. A method of protecting a penetration in a wall of a building against weather, the method comprising the step of:

inserting a utility through an opening in the wall of the building;

providing a weather barrier, comprising:

a sheet of precipitation and wind resistant material, the sheet comprising a utility receiving chamber surrounded by a planar, building engaging section, the utility receiving chamber comprising a sidewall that extends perpendicularly to a plane defined by the building engaging section; and

a structural collar that is sized and shaped to be friction fit within the sidewall of the utility receiving chamber, the structural collar being movable along the sidewall upon application of a sliding force, the structural collar having an inner circumference that is the same as or greater than an outer circumference of the utility;

placing the weather barrier over the utility such that the utility is received within the utility receiving chamber and the building engaging section is immediately adjacent to the wall;

after placing the weather barrier over the utility, moving the structural collar within the sidewall and relative to the utility; and

applying a finishing material to the wall of the building, the finishing material overlying at least a portion of the building engaging section of the sheet.

8. The method of claim 7 , wherein the utility receiving chamber comprises a closed end wall that is spaced from the plane of the building engaging section.

9. The method of claim 8 , further comprising the step of removing at least a portion of the end wall of the utility receiving chamber to provide access to the utility.

10. The method of claim 9 , wherein removing at least a portion of the end wall comprises removing a portion of the sidewall.

11. The method of claim 7 , wherein the structural collar comprises a closed end that is spaced outward from the sheet in the direction of the sidewall.

12. The method of claim 11 , further comprising the step of removing at least a portion of the closed end of the structural collar to provide access to the utility.

13. The method of claim 12 , wherein removing at least a portion of the closed end comprises removing a portion of the sidewall of the structural collar.

14. The method of claim 7 , further comprising the step of removing the structural collar from the utility receiving chamber.

15. The method of claim 7 , wherein at least the utility receiving chamber is resilient.

16. The method of claim 7 , wherein the utility receiving chamber and the building engaging section are integrally formed.

17. The method of claim 7 , wherein the sidewall has a rectangular or a rounded cross-section.

18. The method of claim 7 , wherein placing the weather barrier over the utility comprises sealingly engaging the inner circumference of the structural collar and the outer circumference of the utility.

19. The method of claim 7 , wherein the structural collar extends from the utility receiving chamber to traverse the plane defined by the building engaging section.
