Abstract

A backed paneling unit comprised of a backing portion that includes at least one of a depth portion and an elevated portion. An elevated portion and/or a depth portion may be formed using any suitable method including, but not limited to, molding, machining and heat stamping. Optionally, a backing portion may comprise a hydrophobic material. Such features may enable fluid flow (e.g., ventilation or liquid drainage) behind the backing portion.

Claims

1. A siding panel unit adapted to be installed on an underlying structure, said siding panel unit comprising:

a vinyl facing portion; and

a foamed plastic backing portion secured to said facing portion, said backing portion comprising a primary rear surface that is substantially planar, a plurality of elevated portions relative to said primary rear surface, and a plurality of depth portions relative to said primary rear surface;

wherein at least one of said depth portions is situated between said elevated portions.

2. The siding panel unit of claim 1 wherein said elevated portions are substantially parallel to each other.

3. The siding panel unit of claim 1 wherein said depth portions are substantially parallel to each other.

4. The siding panel unit of claim 1 wherein said elevated portions are substantially parallel to said depth portions.

5. The paneling unit of claim 1 wherein said at least one of said depth portions has a depth between about 0.0625 inches and about 0.1000 inches and a width of about 0.1875 inches.

6. The siding panel unit of claim 1 wherein said depth portions are spaced about every 3.25 inches.

7. The siding panel unit of claim 1 wherein said elevated portions and said depth portions are comprised of shapes selected from the group consisting of straight portions, diamonds, circles, spheres, squares, cubes, rectangles, ovals, ellipses, triangles, cones, cylinders, parallelograms, curves, and other polygons.

8. A siding panel unit adapted to be installed on an underlying structure, said siding panel unit comprising:

a vinyl facing portion; and

a foamed plastic backing portion secured to said facing portion, said backing portion comprising a primary rear surface that is substantially planar, a plurality of elevated portions relative to said primary rear surface, and a plurality of depth portions relative to said primary rear surface;

wherein at least one of said elevated portions is situated between said depth portions.

9. The siding panel unit of claim 8 wherein said elevated portions are substantially parallel to each other.

10. The siding panel unit of claim 8 wherein said depth portions are substantially parallel to each other.

11. The siding panel unit of claim 8 wherein said elevated portions are substantially parallel to said depth portions.

12. The siding panel unit of claim 8 wherein said at least one of said elevated portions has a height of about 0.045 inches and a width of about 0.500 inches.

13. The siding panel unit of claim 8 wherein said elevated portions are spaced about every 3.25 inches.

14. The siding panel unit of claim 8 wherein said elevated portions and said depth portions are comprised of shapes selected from the group consisting of straight portions, diamonds, circles, spheres, squares, cubes, rectangles, ovals, ellipses, triangles, cones, cylinders, parallelograms, curves, and other polygons.

15. A siding panel unit adapted to be installed on an underlying structure, said siding panel unit comprising:

a vinyl facing portion; and

a foamed plastic backing portion secured to said facing portion, said backing portion comprising a primary rear surface that is substantially planar, a plurality of elevated portions relative to said primary rear surface, and a plurality of depth portions relative to said primary rear surface;

wherein at least one of said depth portions is situated between said elevated portions; and

wherein at least one of said elevated portions is situated between said depth portions.

16. The siding panel unit of claim 15 wherein said elevated portions are substantially parallel to each other.

17. The siding panel unit of claim 15 wherein said depth portions are substantially parallel to each other.

18. The siding panel unit of claim 15 wherein said elevated portions are substantially parallel to said depth portions.

19. The siding panel unit of claim 15 wherein said elevated portions and said depth portions alternate across a length of said backing portion.

20. The siding panel unit of claim 15 wherein said elevated portions and said depth portions are at an angle of about 60 degrees relative to horizontal.
