Claim:
A composite panel comprising: a foam backer having a front side, a back side, a top edge, and a bottom edge; and a siding panel consisting of a planar front face, a rear face, a top edge, a bottom edge, and a lip extending perpendicularly from the rear face of the siding panel at the bottom edge of the siding panel, wherein the bottom edge of the siding panel extends beyond the bottom edge of the foam backer so that a portion of the rear face of the siding panel does not contact the foam backer; wherein the rear face of the siding panel is attached to the front side of the foam backer; wherein the top edge of the foam backer is angled downward from a first height at the front side of the foam backer to a second height at the back side of the foam backer, with the top edge of the foam backer at the front side being aligned with the top edge of the siding panel; wherein the bottom edge of the foam backer consists of a rear angled portion complementary to the top edge of the foam backer and a front level portion complementary to the shape of the top edge of the siding panel; and wherein the lip is spaced apart from the bottom edge of the foam backer such that when composite panels are stacked upon each other, an overlap region containing no foam is formed.
