Reinforced exterior siding
First Claim
1. An exterior finishing panel, comprising an elongated thermoplastic sheet including an outwardly-facing surface having an aesthetic appearance and an inwardly-facing surface;
- a relatively rigid rod disposed along a portion of a length of said thermoplastic sheet, said rod having a flexural modulus substantially greater than a flexural modulus of said thermoplastic sheet;
said elongated thermoplastic sheet comprising a plurality of rectangular sheathing sections having lateral marginal flanges;
wherein said rod comprises an extruded reinforced thermoplastic.

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 rigid support member has a flexural modulus which is significantly greater than the modulus of the thermoplastic sheet, so as to support the panel during handling and installation. 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.

20. The method of installing exterior siding, comprising:
-
providing an elongated, thermoplastic sheet of exterior siding material including an outwardly-facing surface having an aesthetic appearance, and an inwardly-facing surface; and
a relatively rigid reinforced thermoplastic rod disposed along a portion of a length of said thermoplastic sheet, said relatively rigid rod having a significantly greater flexural modulus than said thermoplastic sheet, andfastening said thermoplastic sheet to an exterior surface of a building, whereby said relatively rigid reinforced thermoplastic rod permits said thermoplastic sheet to float across a plurality of irregularities on said exterior surface.
