Abstract

Exterior finishing panels are provided which contain an elongated, thermoplastic sheet which is supported by a rigid support member disposed along a portion of the length of the sheet. The panels of this invention will be more kink-resistant, and will ride uneven walls better to present a flatter-looking finished wall surface. These panels are also capable of being worked with ordinary hand tools, such as a standard wood saw made of steel or carbide.

Claims

1. An exterior finishing panel comprising:

an elongated thermoplastic sheet including an outwardly-facing surface having an aesthetic appearance and an inwardly-facing surface, said elongated thermoplastic sheet including at least on nailing flange having a plurality of apertures therethrough for receiving plurality of fasteners for fastening said exterior finishing panel to an exterior wall of a building;

an elongated reinforcing member bonded substantially only along a portion of the exterior finishing panel by a melt bond, said panel and elongated reinforcing member capable of being cut by a saw blade.

2. The exterior finishing panel of claim 1, wherein said elongated reinforcing member comprises a flexural modulus which is relatively greater than the flexural modulus of said thermoplastic sheet.

3. The exterior finishing panel of claim 1, wherein said elongated thermoplastic sheet is configured into the shape of a piece of vertical or horizontal siding, a soffit, or siding accessory.
