Abstract

Disclosed herein are embodiments of foam backing panels for use with lap siding and configured for mounting on a building. Also disclosed are lap siding assemblies and products of lap sidings. One such embodiment of the foam backing panel comprises a rear face configured to contact the building, a front face configured for attachment to the lap siding, alignment means for aligning the lap siding relative to the building, means for providing a shadow line, opposing vertical side edges, a top face extending between a top edge of the front face and rear face and a bottom face extending between a bottom edge of the front face and rear face.

Claims

1. 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.

2. The composite panel of claim 1, wherein the lip has a length of from about 0.313 inches to about 0.75 inches.

3. The composite panel of claim 1, wherein the foam backer further comprises a drainage system in the back side.

4. The composite panel of claim 3, wherein the drainage system comprises intersecting channels in the back side of the foam backer.

5. The composite panel of claim 1, having an R-value of from 3.5 to 4.0.

6. The composite panel of claim 1, wherein the composite panel has a thickness of from 1 inch to 1.25 inches.

7. The composite panel of claim 1, wherein the siding panel has a thickness of less than 0.13 inches.

8. The composite panel of claim 1, wherein the foam backer is made from expanded polystyrene.

9. The composite panel of claim 1, wherein the siding panel is made of fiber cement.

10. The composite panel of claim 1, wherein the foam backer comprises a chemical additive to deter termites and carpenter ants.
