A corrosion-resistant lath is provided for use in exterior finishing systems, such as stucco systems and exterior insulation and finish systems (“EIFS”). The lath includes in a first embodiment an open, woven fabric comprising weft and warp yarns containing non-metallic fibers, such as glass fibers.
A corrosion-resistant lath is provided for use in exterior finishing systems, such as stucco systems and exterior insulation and finish systems (“EIFS”). The lath includes in a first embodiment an open, woven fabric comprising weft and warp yarns containing non-metallic fibers, such as glass fibers. A portion of the weft yarns are undulated, resulting in an increased thickness for the fabric. The fabric is coated with a polymeric resin for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making an exterior finish system and building wall including an exterior finish system using such a lath.

1. A building wall comprising: a building wall substrate;a corrosion-resistant woven lath attached to said substrate, said lath comprising warp and weft yarns comprising non-metallic fibers, wherein a portion of said warp yarns are heavier than a portion of said weft yarns and said warp yarns are fewer in number than said weft yarns, and wherein at least a portion of said weft yarns are undulated when viewed in the plane of the lath; anda stucco matrix applied to said lath. 2. A building wall comprising: a building wall substrate;an insulation board attached to the substrate;a base coat applied to the insulation board;a reinforcing mesh comprising warp and weft yarns comprising non-metallic fibers, wherein a portion of said warp yarns are heavier than a portion of said weft yarns and said warp yarns are fewer in number than said weft yarns and wherein at least a portion of said weft yarns are undulated when viewed in the plane of the mesh; anda finish coat applied to said reinforcing mesh, wherein the reinforcing mesh is substantially embedded within the base coat and the finish coat. 3. The building wall of claim 1, wherein the non-metallic fibers are selected from the group consisting of polymeric fibers, glass fibers, and combinations thereof. 4. The building wall of claim 3, wherein said non-metallic fibers comprise glass fibers. 5. The building wall of claim 4, wherein said glass fibers are selected from the group consisting of E-glass fibers, A-glass fibers, ECR-glass fibers, S-glass fibers, AR-glass fibers and combinations thereof. 6. The building wall of claim 5, wherein said glass fiber comprise AR-glass fibers. 7. The building wall of claim 6, wherein said fabric comprises a leno weave. 8. The building wall of claim 7, wherein said weft yarns are fixed in said undulated condition when viewed in the plane of the lath by a polymeric coating. 9. The building wall of claim 8, wherein at least a portion of said weft yarns are fixed in a substantially sinusoidal pattern when view in the plane of the lath. 10. The building wall of claim 8, wherein said polymeric coating comprises an alkaline resistant coating. 11. The building wall of claim 2, wherein the non-metallic fibers are selected from the group consisting of polymeric fibers, glass fibers, and combinations thereof. 12. The building wall of claim 11, wherein said non-metallic fibers comprise glass fibers. 13. The building wall of claim 12, wherein said glass fibers are selected from the group consisting of E-glass fibers, A-glass fibers, ECR-glass fibers, S-glass fibers, AR-glass fibers and combinations thereof. 14. The building wall of claim 13, wherein said glass fiber comprise AR-glass fibers. 15. The building wall of claim 14, wherein said fabric comprises a leno weave. 16. The building wall of claim 15, wherein said weft yarns are fixed in said undulated condition when viewed in the plane of the lath by a polymeric coating. 17. The building wall of claim 16, wherein at least a portion of said weft yarns are fixed in a substantially sinusoidal pattern when view in the plane of the lath. 18. The building wall of claim 16, wherein said polymeric coating comprises an alkaline resistant coating.
