Abstract

A vapor barrier cover for installation to an electrical box in the rough-in phase of construction. The vapor barrier cover includes a flange with an opening having an inner periphery and a body extending from the inner periphery of the flange. The body includes walls extending to a front edge. A front wall extending from the front edge includes a front opening and a rearward extending wing. Installation of the vapor barrier cover enables inspection and testing for air-tightness around the periphery of the electrical box prior to the final phase of construction and without the need for a gasket.

First claim

What is claimed is:

1. A vapor barrier cover for reducing air infiltration around an electrical box, comprising:
a flange with an opening having an inner periphery, said flange including a rear face;
a body extending from the inner periphery of the flange;
said body including side walls and end walls extending to a front edge;
a front wall extending inward from said front edge, said front wall including a back surface;
said front wall including a front opening therein;
a wing extending from the front wall, said wing including a rear edge; and
a truncated edge on said wing, said truncated edge narrowing the wing at the rear edge.

2. The vapor barrier cover of claim 1 , comprising a channel defined by the side walls, the end walls, and the front wall of said body.

3. The vapor barrier cover of claim 1 , comprising an inner aperture and a flashed-over aperture on the front wall, said flashed-over aperture passing partially through the front wall toward the back surface.

4. The vapor barrier cover of claim 3 , comprising said a thin skin extending across the back surface of the front wall at the flashed-over aperture.

5. A vapor barrier cover for reducing air infiltration around an electrical box, comprising:
a flange with an opening having an inner periphery, said flange including a rear face;
a body extending from the inner periphery of the flange;
said body including side walls and end walls extending to a front edge;
a front wall extending inward from said front edge, said front wall including a back surface;
said front wall including a front opening therein;
an inner aperture and a flashed-over aperture on the front wall;
said flashed-over aperture passing partially through the front wall toward the back surface; and
a thin skin extending across the back surface of the front wall at the flashed-over aperture.

6. The vapor barrier cover of claim 5 , comprising:
a wing extending from the front wall, said wing including a rear edge; and
a truncated edge on said wing, said truncated edge narrowing the wing at the rear edge.
