Abstract

A Stucco Composite Building Panel is disclosed, in which a sheet of exterior wall sheathing and a cement board are attached together to form an improved sheet of building material for the construction of exterior stucco walls. This composite building panel reduces the amount of individual layers required to build a conventional stucco wall by providing an exterior wall building panel that is mounted directly to the stud framing that is ready for a finish layer of stucco to be applied.

Claims

1. A composite building panel comprising:

a sheet of exterior wall sheathing and a layer of cementitious board, wherein the cement board is laminated to one side of the sheathing forming a stucco wall building material sheet with shear strength that is ready to receive a finish layer of stucco replacing the base coat of conventional stucco methods.

2. The composite building panel of claim 1, wherein a water resistant coating is applied to the sheathing to protect the wall from moisture.

3. The composite building panel of claim 1, wherein, the adhesive that bonds the cement board to the sheathing contains a water resistant acrylic.

4. The composite building panel of claim 1, wherein a sheet of black builders paper is laminated in between the cement board and the sheathing to function as a water resistant barrier.

5. The composite building panel of claim 1, wherein a sheet of black builders paper is laminated to the back of the sheathing to function as a water resistant barrier.

6. The composite building panel of claim 1, wherein a sheet of spunbond olefin fiber such as Tyvek is laminated in between the cement board and the sheathing to function as a water resistant barrier.

7. The composite building panel of claim 1, wherein a sheet of spunbond olefin fiber such as Tyvek is laminated to the back of the sheathing to function as a water resistant barrier.

8. The composite building panel of claim 1, wherein, the method of installation includes a moisture resistant sealant applied to the butt joint edges preventing water damage or other elements from damaging the wall.

9. The composite building panel of claim 1, wherein, the method of installation includes a water resistant mortar applied over mesh tape to seal the joining edges, preventing cracking and creating a sealed exterior wall ready for a final finish coat of stucco.

10. The composite building sheet of claim 1, wherein, the method of installation includes filling the seams and joints in with elastomeric joint tape and joint sealer after it is mounted, to prevent moisture penetration and cracking at the joints.

11. The composite building panel of claim 1, wherein, the method of installation includes fasteners such as screws, nails or staples with the sheathing portion of the composite panel preventing fasteners from pulling through.

12. The composite building panel of claim 1, wherein, the composite board consists of a sheet of cement board such as Durock laminated to a sheet of sheathing.

13. The composite building panel of claim 1, wherein, the composite board consists of a sheet of fiber cement board such as Hardie Backer laminated to a sheet of sheathing.

14. The composite building panel of claim 1, wherein, the composite board consists of a sheet of cement board laminated to a sheet of plywood sheathing.

15. The composite building panel of claim 1, wherein, the composite board consists of a sheet of cement board laminated to a sheet of fiberglass gypsum sheathing such as DensGlass Gold.

16. The composite building panel of claim 1, wherein, the composite board consists of a sheet of cement board laminated to a sheet of sheathing material manufactured from polymer.

17. The composite building panel of claim 1, wherein, the composite board consists of a sheet of cement board laminated to a sheet of oriented strand board sheathing.

18. The composite building panel of claim 1, wherein, the composite board consists of a sheet of fiber cement board such as Hardie Backer laminated to a sheet of plywood sheathing.

19. The composite building panel of claim 1, wherein, the composite board consists of a sheet of fiber cement board laminated to a sheet of fiberglass gypsum sheathing such as DensGlass Gold.

20. The composite building panel of claim 1, wherein, the composite board consists of a sheet of fiber cement board laminated to a sheet of sheathing material manufactured from polymer.

21. The composite building panel of claim 1, wherein, the composite board consists of a sheet of fiber cement board laminated to a sheet of sheathing material manufactured from fiberglass.

22. The composite building panel of claim 1, wherein, the layer of fiber cement board laminated together with the substrate makes cement board easier to cut with a skill saw, jigsaw, or other cutting means without the cement board crumbling.
