Abstract
Siding including composite building material and an interlocking mechanism are provided. The panels, possibly in conjunction with particular fasteners, include interlocking elements and may be formed from a composite building material having a foamed substrate having a foamed inner core and a dense integral skin, wherein the foamed substrate includes a polymer matrix and a reinforcing filler, and a urethane/acrylic coating applied to the foamed substrate at the front face of the siding panel, wherein the coating includes an IR-reflective pigment, wherein the urethane/acrylic coating is chemically and/or physically bound to the substrate.
Claims10
A siding system, comprising:
- a siding panel having
- an upper portion having a plurality of apertures therethrough, and
- a lower portion having a downward protrusion adjacent an undercut;
- and
- a fastener having
- a head portion having an inner wall, an outer wall, and a channel formed between the inner wall and the outer wall, and
- an elongated driving portion extending from the head portion and configured to be driven through the apertures of the siding panel, and into an underlying structure, the inner wall of the head portion contacting the siding panel to constrain the siding panel against the underlying structure when the driving portion is driven through the aperture and into the underlying structure,
- wherein, when the fastener is received in the aperture of the siding panel, the channel of the fastener is configured to receive the downward protrusion of a like siding panel, thereby constraining the like siding panel against movement in an outward direction away from the underlying structure.
A method of forming siding panels, comprising:
- forming a composite board having a low-density, foamed inner core and a high-density integral outer skin;
- routing each of two opposite sides of the board to form an undercut;
- and
- diagonally cutting the board to form and separate the siding panels, the show surfaces of the siding panels corresponding to the surfaces formed during the diagonal cutting.
