Plastic siding panel

A monolithic molded plastic siding panel comprising:

• a panel body having a top edge, a bottom edge, a front surface, and a rear surface;
• an attachment portion extending along the top edge of the panel body and defining a plurality of apertures therein, said apertures becoming more elongated with position away from a first position on the attachment portion;
• a lower interlocking mechanism extending across the length of said rear surface, said lower interlocking mechanism having a lower sidewall offset from said rear surface in the rearward direction, said lower sidewall having a free lip portion;
• an upper interlocking mechanism extending at least partially across the length of said front surface, said upper interlocking mechanism defining an upper elongated cavity adapted to accept the free lip portion of the lower sidewall, the upper interlocking mechanism having,
• an upper sidewall offset from said front surface in the frontward direction, said upper sidewall having a free bottom edge,
• a plurality of ledges, each ledge extending from the front surface to the upper sidewall and extending partially across the length of said front surface;
• and
• an aperture region offset vertically from each ledge, each aperture region having a set of apertures, the set of apertures having at least a first aperture of a first elongation and a second aperture of a second elongation differing from the first elongation.

A monolithic molded plastic siding panel comprising:

• a panel body having a top edge, a bottom edge, a front surface, and a rear surface, the panel body being made of a thermoplastic resin selected from the group consisting of a polyolefin, a polycarbonate, polyvinyl chloride, and mixtures and copolymers thereof, wherein said front surface of the body has a shake-shingle pattern molded therein;
• an attachment portion extending along the top edge of the panel body and defining a plurality of apertures therein, said apertures becoming more elongated with position away from a center position on the attachment portion;
• a top interlocking mechanism extending across the length of said front surface, said top interlocking mechanism having a plurality of top ledges extending from the front surface by some top ledge width and along the front surface by some top ledge length and defining a plurality of top ledge slots therebetween, each of the top ledges connected with a first sidewall extending downward from said top ledges, offset from the front surface and defining a recess between the front surface and the sidewall;
• an aperture region above each top ledge, each aperture region having a set of apertures having at least a first aperture of a first elongation, a second aperture of a second elongation differing from the first elongation, and a third aperture of a third elongation differing from the first elongation and the second elongation;
• and
• a bottom interlocking mechanism extending without interruption across the length of said rear surface, said bottom interlocking mechanism having a bottom ledge extending from the rear surface connected with a second sidewall extending upward from said bottom ledge.
