Abstract: A siding panel assembly comprising includes a siding panel having a substantially planar member having an upper portion angled outwardly and a pair of first apertures proximate a lateral edge of the substantially planar member. A flange with a pair of notches extends from the substantially planar member and terminates in a lip extending downwardly from a rear edge of the flange. A recess is formed in a rear surface of the substantially planar member. A first insulating panel is secured to the siding panel. A splicing member includes a first substantially planar member, a pair of flanges, a shoulder extending inwardly from the first substantially planar member, a second substantially planar member extending downwardly, and a pair of projections. A second insulating panel is secured to a rear surface of the splicing member.

Abstract: A composite siding panel has a core including PVC resin, wood flour in an amount of about 75 to about 300 parts per hundred parts of PVC resin, a thermal stabilizer in an amount of about 1.2 parts per hundred parts of PVC resin, and a wood stabilizer in an amount of about 0.5 to about 3 parts per hundred parts of PVC resin; and a cap covering a front, a back, a bottom, and a top of the core.
