Abstract

A duct flashing panel configured to provide weatherproofing for single wall ducts extending through the walls of a structure and having a terminal end extending outside of the structure. The duct flashing panel includes a panel body and an elastomeric collar sized and configured to circumferentially engage the exterior surface of the duct to form a fluid-tight seal between the duct and the collar to prevent fluid migration along the exterior of the duct. The collar includes an annular bead which provides rigidity and strength to the collar to urge the collar into compressive engagement with the exterior surface of the duct.

Claims

1. A method of installing a flashing panel over a duct, the method comprising the steps of:

placing a first sheet over the duct, with the duct extending through an opening formed in the first sheet;

advancing the flashing panel over the duct after placing the first sheet over the duct, the flashing panel comprising;

a panel body having a first surface, an opposing second surface, and a panel opening extending through the panel body between the first and second surfaces;

a resilient collar coupled to the panel body and extending radially inward into the panel opening, the collar defining a collar opening aligned with the panel opening, the collar being sized and configured to be engageable with the duct and to apply a compressive force thereto when engaged therewith; and

an annular bead coupled to the collar to enhance the compressive force applied to the duct, the resilient collar extending from the panel body in a radially inward direction relative to the panel body and terminating at the annular bead;

the duct extending through the collar opening and the collar exerting the compressive force on the duct when the flashing panel is advanced over the duct; and

placing a second sheet over the duct after the advancing step, with the duct extending through an opening formed in the second sheet,

the first sheet being disposed adjacent the first surface of the panel body, and the second sheet being disposed adjacent the second surface of the panel body.

2. The method of claim 1, further comprising the step of fastening the first sheet to a frame member.

3. The method of claim 1, wherein upon advancing the flashing panel over the duct, an outer surface of the resilient collar forms a concave configuration.

4. The method of claim 1, wherein the advancing step includes transitioning the resilient collar from a relaxed configuration toward a compressive configuration, the resilient collar defining an inner collar diameter that increases as the resilient collar transitions from the relaxed configuration toward the compressive configuration.

5. The method of claim 1, wherein the advancing step includes advancing the flashing panel over the duct along an axis about which the panel body and the resilient collar are coaxially aligned.

6. The method of claim 1, further comprising the step of securing the panel body to a frame member.

7. A method of installing a flashing panel over a duct, the method comprising the steps of:

placing a first sheet over the duct, with the duct extending through an opening formed in the first sheet;

advancing the flashing panel over the duct, the flashing panel comprising a panel body having a panel body opening and a resilient collar coupled to the panel body and extending from the panel body into the panel body opening, the collar having an annular bead extending around a collar opening coaxially aligned with the panel opening;

applying a compressive force on the duct by the resilient collar to form a seal around the duct;

placing a second sheet over the duct after the advancing step, with the duct extending through an opening formed in the second sheet,

the first sheet being disposed adjacent a first surface of the panel body, and the second sheet being disposed adjacent a second surface of the panel body.

8. The method of claim 7, wherein in the advancing step, the annular bead defines a radially inner-most portion of the resilient collar.

9. The method of claim 7, further comprising the step of fastening the first sheet to a frame member.

10. The method of claim 7, wherein upon advancing the flashing panel over the duct, an outer surface of the resilient collar forms a concave configuration.

11. The method of claim 7, wherein the advancing step includes transitioning the resilient collar from a relaxed configuration toward a compressive configuration, the resilient collar defining an inner collar diameter that increases as the resilient collar transitions from the relaxed configuration toward the compressive configuration.

12. The method of claim 7, wherein the advancing step includes advancing the flashing panel over the duct along an axis about which the panel body and the resilient collar are coaxially aligned.

13. The method of claim 7, further comprising the step of securing the panel body to a frame member.
