Abstract

An apparatus and method for a drainage system of an exterior wall of a building comprising insulation having a rear face for contact with the exterior wall of the building and a drainage plane positioned on the rear face for removal of water from the exterior wall.

Claims

1. A siding panel for mounting on an exterior wall of a building comprising:

a siding component having a top end and a bottom end, the bottom end comprising a locking flange with a plurality of apertures defined therein; and

a foam panel backing including a main body portion having a rear face and a front face, a pocketed end, and a top end opposite the pocketed end;

wherein the rear face is mountable on the exterior wall and includes a plurality of drainage grooves over the entire rear face operable to remove water from a surface of the exterior wall;

wherein the pocketed end has a front face contiguous with the front face of the main body portion and a rear face spaced from the rear face of the main body portion to form a step with a bottom edge of the rear face, both the bottom edge of the rear face and the rear face of the pocketed end including a plurality of exit grooves positioned along the pocketed end, the exit grooves each having an origin and a terminus, the origin of each exit groove contiguous and in fluid communication with at least one drainage groove defined in the rear face of the main body portion, the terminus of each exit groove located at a bottom edge of the rear face of the pocketed end and in fluid communication with the plurality of apertures of the locking flange to facilitate the removal of water away from a surface of the exterior wall;

wherein the top end of the foam panel backing has a lip that extends over the top end of the siding component, and wherein the top end of the foam panel backing has a single smooth top surface.

2. The siding panel of claim 1, wherein the plurality of drainage grooves comprises a network of grooves positioned in a diamond grid pattern oriented at an angle of thirty degrees (30°

) from vertical.

3. The siding panel of claim 1, wherein the plurality of drainage grooves comprises a network of grooves positioned in a diagonal pattern oriented at an angle of forty-five degrees (45°

) from vertical.

4. The siding panel of claim 1, wherein the plurality of drainage grooves comprises a network of grooves positioned in a vertical pattern.

5. The siding panel of claim 1, wherein the plurality of exit grooves comprises a network of grooves positioned in a vertical pattern.

6. The siding panel of claim 1, wherein each drainage groove and each exit groove has a tapered bottom for increased water flow due to reduced surface tension.

7. The siding panel of claim 1, wherein each drainage groove and each exit groove has a rounded bottom for increased water flow due to reduced surface tension.

8. The siding panel of claim 1, wherein each drainage groove and each exit groove has a tapered edge to encourage water to flow freely.

9. The siding panel of claim 1, wherein the siding component further comprises a nail strip including a plurality of nail apertures for securing the siding panel to the exterior wall of the building.

10. The siding panel of claim 1, wherein the siding component further comprises a locking lip located proximate to a top edge of the siding panel and configured to operably engage the locking flange of an adjacent siding panel.

11. A foam panel backing for mounting on an exterior wall, comprising:

a main body portion having a rear face and a front face opposite the rear face, a pocketed end, and a top end opposite the pocketed end;

wherein the rear face is mountable on the exterior wall and includes a plurality of drainage grooves over the entire rear face operable to remove water from a surface of the exterior wall;

wherein the pocketed end has a front face contiguous with the front face of the main body portion and a rear face spaced from the rear face of the main body portion to form a step with a bottom edge of the rear face, both the bottom edge of the rear face and the rear face of the pocketed end including a plurality of exit grooves positioned along the pocketed end, the exit grooves each having an origin and a terminus, the origin of each exit groove contiguous and in fluid communication with at least one drainage groove defined in the rear face of the main body portion, the terminus of each exit groove located at a bottom edge of the rear face of the pocketed end;

wherein the top end of the foam panel backing has a lip that extends beyond the front face, and wherein the top end of the foam panel backing has a single smooth top surface.

12. The foam panel backing of claim 11, wherein the plurality of drainage grooves comprises a network of grooves positioned in a diamond grid pattern oriented at an angle of thirty degrees (30°

) from vertical.

13. The foam panel backing of claim 11, wherein the plurality of drainage grooves comprises a network of grooves positioned in a diagonal pattern oriented at an angle of forty-five degrees (45°

) from vertical.

14. The foam panel backing of claim 11, wherein the plurality of drainage grooves comprises a network of grooves positioned in a vertical pattern.

15. The foam panel backing of claim 11, wherein the plurality of exit grooves comprises a network of grooves positioned in a vertical pattern.

16. The foam panel backing of claim 11, wherein each drainage groove and each exit groove has a tapered bottom for increased water flow due to reduced surface tension.

17. The foam panel backing of claim 11, wherein each drainage groove and each exit groove has a rounded bottom for increased water flow due to reduced surface tension.

18. The foam panel backing of claim 11, wherein each drainage groove and each exit groove has a tapered edge to encourage water to flow freely.
