Abstract

Stucco support structures and stucco wall systems incorporating the stucco support structures are provided. The stucco support structure includes a structural layer of composite material. The composite material includes a homogenous matrix of a gypsum material and a polymer resin material, and wet-use chopped strand fibers that are filamentized within the homogenous matrix. The stucco support structure also includes a stucco adhesion member interfaced with the structural layer that is configured to receive and bond a stucco material to the structural layer. The stucco support structure eliminates the need for sheathing and wire mesh lath conventionally used in stucco applications.

First claim

What is claimed is:

1 . A structure for supporting a stucco material, the structure comprising:
a) a structural layer of composite material comprising:
i) a homogenous matrix of a gypsum material and a polymer resin material; and
ii) wet-use chopped strand fibers, wherein the wet-use chopped strand fibers are substantially filamentized within the homogenous matrix; and
b) a stucco adhesion member interfaced with the structural layer.

2 . The structure of claim 1 , further comprising a reinforcement layer disposed on a surface of the structural layer opposite the stucco adhesion member.

3 . The structure of claim 1 , wherein the stucco adhesion member extends from a surface of the structural layer, and wherein the stucco adhesion member comprises a stucco adhesion layer comprising at least one of strands, filaments, fibers, an unbonded woven mat, an unbonded non-woven mat, a mesh, an entangled net material, a non-woven mat held together with a binder, a woven mat held together with a binder, and combinations thereof.

4 . The structure of claim 3 , wherein the stucco adhesion layer comprises one or more of fiberglass fibers, polymer fibers, and an entangled net material.

5 . The structure of claim 1 , wherein the stucco adhesion member is attached to a surface of the structural layer, and wherein the stucco adhesion member comprises a stucco adhesion layer comprising at least one of strands, filaments, fibers, an unbonded woven mat, an unbonded non-woven mat, a mesh, an entangled net material, a non-woven mat held together with a binder, a woven mat held together with a binder, and combinations thereof.

6 . The structure of claim 5 , wherein the stucco adhesion layer comprises one or more of fiberglass fibers, polymer fibers, and an entangled net material.

7 . The structure of claim 1 , wherein the stucco adhesion member comprises one or more of grooves, undercuts, and undulations formed in the structural layer.

8 . The structure of claim 1 , wherein the stucco adhesion member is means for receiving and bonding the stucco material to the structural layer, wherein the structural layer eliminates the need for a sheathing, and wherein the stucco adhesion member eliminates the need for a wire mesh lath.

9 . The structure of claim 1 , further comprising a drainage path.

10 . The structure of claim 9 , wherein the drainage path comprises one or more of valleys of undulations formed in the structural layer, grooves formed in the structural layer, and pores formed in the structural layer.

11 . A system for forming a stucco wall on a plurality of frame members, the system comprising:
a) a stucco support structure attached to the frame members, wherein the stucco support structure comprises:
i) a structural layer of composite material comprising:
1) a homogenous matrix of a gypsum material and a polymer resin material; and
2) wet-use chopped strand fibers, wherein the wet-use chopped strand fibers are substantially filamentized within the homogenous matrix; and

ii) a stucco adhesion member interfaced with the structural layer; and
b) at least one stucco coat applied to the stucco adhesion member; wherein the stucco support structure eliminates the need for a sheathing and a wire mesh lath.

12 . The system of claim 11 , wherein the stucco adhesion member extends from a surface of the structural layer, and wherein the stucco adhesion member comprises a stucco adhesion layer comprising at least one of strands, filaments, fibers, an unbonded woven mat, an unbonded non-woven mat, a mesh, an entangled net material, a non-woven mat held together with a binder, a woven mat held together with a binder, and combinations thereof.

13 . The system of claim 11 , wherein the stucco adhesion member is attached to a surface of the structural layer, and wherein the stucco adhesion member comprises a stucco adhesion layer comprising at least one of strands, filaments, fibers, an unbonded woven mat, an unbonded non-woven mat, a mesh, an entangled net material, a non-woven mat held together with a binder, a woven mat held together with a binder, and combinations thereof.

14 . The system of claim 11 , wherein the stucco adhesion member comprises one or more of grooves, undercuts, and undulations formed in the structural layer.

15 . The system of claim 11 , further comprising a foam panel positioned between the stucco support structure and the frame members.

16 . The system of claim 15 , wherein the foam panel comprises one or more drainage structures in the foam panel configured to allow moisture to drain out of the stucco wall.

17 . A system for forming a stucco wall on a plurality of frame members, the system comprising:
a) a substrate attached to the frame members, the substrate having an interior facing surface and an exterior facing surface; b) an entangled net material extending from the exterior facing surface of the substrate; and c) at least one stucco coat on the entangled net material; wherein the at least one stucco coat partially extends through a portion of a thickness of the entangled net material to define a compliance zone comprised of the entangled net material extending from the exterior facing surface of the substrate and free of the at least one stucco coat; and wherein the compliance zone absorbs forces to reduce or prevent cracking of the at least one stucco coat.

18 . The system according to claim 17 , wherein the substrate comprises one or more of: a rigid insulation board; a panel of composite material; oriented strand board; plywood; fiberboard; and cement board.

19 . The system according to claim 17 , wherein the entangled net material comprises a polymer selected from the group consisting of polyamides, polyolefins, polyesters, polyimides, polytetrafluoroethylene, polystyrene, polyvinylchloride, and combinations thereof.

20 . The system according to claim 17 , wherein the substrate comprises an extruded polystyrene board;
wherein the entangled net material comprises a polymer; and wherein the entangled net material is attached to the exterior facing surface of the extruded polystyrene board with an adhesive.
