Exterior insulated finish wall assembly

1. An exterior insulated finish wall assembly comprising:

an exterior panel member comprising a rigid insulative substrate and a base coat selectively disposed on the rigid insulative substrate, the rigid insulative substrate comprising a body portion and a tail portion extending from the body portion, the body portion having a first thickness extending between a first surface and a second surface, and the tail portion having a second thickness less than the first thickness, the second thickness of the tail portion extending between the first surface and a recessed surface, the recessed surface defining a recessed portion extending along a length of a lower edge; and

an insert member configured to be disposed within the recessed portion, the insert member sized and shaped to correspond to the recessed portion, the insert member having a bottom face substantially aligned with the lower edge when disposed within the recessed portion, the insert member having a thickness corresponding to the first thickness minus the second thickness, the insert member comprising the rigid insulative substrate and the base coat selectively disposed on the rigid insulative substrate,

wherein a drainage channel is defined between the tail portion and the insert member when assembled.

2. The assembly of claim 1 , wherein the insert member has a front face, a back face, a top face, and a bottom face, and wherein the top face is sloped from the back face to the front face.

3. The assembly of claim 2 , wherein the base coat is disposed on the front face, the back face and the top face.

4. The assembly of claim 1 , wherein the body portion defines a top edge of the exterior panel member and the tail portion defines a bottom edge of the exterior panel member.

5. The assembly of claim 1 , wherein the base coat is disposed along the recessed surface of the tail portion.

6. The assembly of claim 1 , wherein the tail portion includes a sloped surface extending from the second surface to the recessed surface, the sloped surface corresponding to a sloped top surface of the insert member.

7. The system of claim 1 , wherein the base coat includes a reinforcing mesh.

8. The assembly of claim 2 , wherein the drainage channel extends between the top and front faces of the insert member and the recessed surface of the exterior panel member.

9. An exterior wall panel system comprising:

a frame;

a substrate layer disposed along an exterior side of the frame;

an exterior insulated finish wall assembly disposed along an exterior side of the substrate layer, the exterior insulated finish wall assembly including an exterior wall panel and an insert member, wherein the exterior wall panel comprises a tail portion extending from a body portion and terminating at a lower edge, wherein the body portion has a first thickness and the tail portion has a second thickness less than the first thickness, wherein the insert member has a bottom surface, wherein the insert member is disposed within a recess defined by an interior surface of the tail portion of the exterior wall panel, wherein the bottom surface is substantially aligned with the lower edge, wherein the insert member has a thickness corresponding to the first thickness minus the second thickness, wherein a drainage channel is formed between the exterior wall panel and the insert member, and wherein the exterior wall panel and the insert member each comprise a rigid insulative substrate and a base coat selectively applied to the rigid insulative substrate; and

a flashing disposed within the drainage channel between the exterior wall panel and the insert member.

10. The system of claim 9 ,

wherein the flashing extends above the insert member along a second surface of the exterior wall panel.

11. The system of claim 9 , wherein the drainage channel is configured to direct flow of moisture to an exterior of the exterior insulated finish wall assembly.

12. The system of claim 9 , further comprising:

a moisture barrier disposed between the substrate layer and the exterior insulated finish wall assembly.

13. The system of claim 9 , further comprising:

a second coating disposed along an exterior surface of the rigid insulative substrate.

14. The system of claim 9 , further comprising:

a sealant extending along a bottom edge of the insert member, wherein the drainage channel terminates exterior of the sealant.

15. The system of claim 9 , wherein the base coat includes a reinforcing mesh.

16. The system of claim 9 , wherein the base coat is disposed on the exterior wall panel and the insert member adjacent to the drainage channel.

17. The system of claim 9 , wherein the drainage channel extends along a top face and a front face of the insert member, between the insert member and the exterior panel member.
