Abstract

Exterior trim pieces for use on exteriors of buildings. The exterior trim pieces include outside corner trim pieces, inside corner trim pieces, and framing trim pieces for providing an aesthetically pleasing appearance to an exterior of a building. Each of the trim pieces include a body and at least one flange extending from the body to define a concealing space for hiding siding ends and the like. Each of the trim pieces also includes at least one weather strip to assist in sealing the trim pieces to the exterior to prevent the intrusion of water and other elements behind the trim pieces. Each body of the trim pieces is preferably formed from co-extruded rigid cellular PVC and an acrylic-based protective layer. The rigid cellular PVC and the protective layer are formed in matching colors to yield colored-through trim pieces.

Claims

1. A trim piece for use on an exterior of a building, comprising:

a body defining a face for abutting against the exterior of the building, said body including a flange with a concealing space defined beneath said flange; and

a flexible weather strip disposed on said body in spaced relation to said flange and extending outwardly from said body, said weather strip configured for sealing to the exterior of the building.

2. A trim piece as set forth in claim 1 wherein said face of said body is flat.

3. A trim piece as set forth in claim 2 wherein said weather strip includes a second face for abutting the exterior of the building, said second face extending from said face of said body at an obtuse angle for enhancing sealing of said weather strip to the exterior of the building.

4. A trim piece as set forth in claim 1 wherein said weather strip includes a base disposed on said body and extends outwardly from said base to an end, said weather strip tapering from said base to said end.

5. A trim piece as set forth in claim 1 wherein said weather strip is formed of flexible PVC.

6. A trim piece as set forth in claim 1 wherein said weather strip is less rigid than said body.

7. A trim piece as set forth in claim 1 wherein said body is formed of rigid cellular PVC having a shore D hardness of from 50 to 90 and said weather strip is formed of flexible PVC having a shore A hardness of from 50 to 90.

8. A trim piece as set forth in claim 1 wherein said body includes a first side portion and a second side portion disposed perpendicularly to said first side portion.

9. A trim piece as set forth in claim 1 wherein said body includes a pair of abutment portions configured for abutting the exterior of the building such that an air pocket is defined between said body and the exterior of the building when said body is mounted to the exterior.

10. A trim piece for use on an exterior of a building, comprising:

a body formed of a color and defining at least one face for abutting against the exterior of the building, said body including a flange with a concealing space defined beneath said flange; and

a protective layer disposed on said body for providing weather resistance to said trim piece, wherein said protective layer is formed in said color to match said body such that wear of said protective layer is less visibly noticeable.

11. A trim piece as set forth in claim 10 wherein said protective layer is formed of acrylonitrile styrene acrylate.

12. A trim piece as set forth in claim 10 wherein said protective layer has a thickness of 0.1 inches or less.

13. A trim piece as set forth in claim 12 wherein said protective layer has a thickness of from 0.02 to 0.1 inches.
