Description
COMPOSITE BUILDING MATERIAL
FOR CEMENTITIOUS MATERIAL WALL ASSEMBLY
The present invention relates to a wall assembly having an outer finish layer including stucco, mortar, stone, masonry, concrete, plaster or like cementitious material, and more specifically to a composite building material that is used within such a wall assembly and that prevents the accumulation of moisture therein.
10 Moisture permitted to accumulate within a wall, roof or like structure of a building typically will cause premature deterioration of the structure.
Moisture accumulation can be avoided by providing ventilation/drainage passages within the wall/roof assembly. For example, see U.S. Patent Nos. 5,099,627 issued to Coupon et al. and 6,594,965 B2 and 6,786,013 B2 issued to Coupon and U.S. Patent Application 15 Publication No. 2004/0045242 A1 of Lake, which are all assigned to Benjamin Obdyke, Inc., the assignee of the present application.
Laths are known for use in mounting plaster and like substances to substrates.
For example, see U.S. Patent Nos. 5,287,673 and 5,481,843 issued to Kreikemeier and by U.S. Patent Application Publication No. 2002/0108333 Al of Clayton.
20 Various composite materials have been utilized in wall assemblies. For example, see U.S. Patent Nos. 6,131,353, 6,745,531 B1 and 6,804,922 B1 issued to Egan, 6,395,401 B1 and 6,759,135 B2 issued to Bramlett et al., 5,826,390 issued to Sacks, 6,233,890 B1 issued to Tonyan, 6,869,901 B2, 6,761,006 B2 and 6,550,212 issued to Lubker, II, 5,518,799 issued to Finestone et al., 6,794,316 B1 issued to 25 Buscher et al., and 4,315,392 issued to Sylvest and JP 1-83805 of Sato.
Although the drainage and/or ventilation products, building papers, house-wraps, laths and composite materials disclosed in the above referenced patents may function satisfactorily for their intended purpose, there remains a need for a composite building material for use in the assembly of a wall, roof or like structure having an 30 exterior finish layer including a cementitious material, such as stucco.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, FIGs. 1 and lA illustrate a wall assembly 10 of a building structure. Of course, the assembly can also be utilized to form roofs or 25 other structures of a building. The assembly 10 includes an inner structural component, 12 or 14. In the illustrated embodiment, the inner structural component is provided as an inner sheathing member 12 that is affixed to support posts, or studs, 14. The inner sheathing member 12 can be panels of plywood, oriented strand board, particle board, insulated concrete, or like materials permitted by local building codes.
30 Alternatively, the inner structural component can be provided by the support posts, or studs, 14, such as when open stud construction is utilized. In open stud construction, the sheathing members 12 would be eliminated.
A composite building material 16 is fastened as an integral unit to an external side of the inner sheathing member 12. Alternatively, the composite building material 5 is fastened directly to the studs 14 when open stud construction is utilized. The composite building material l 6 provides a support for cementitious material applied thereto. The cementitious material 18 can be stucco, mortar, plaster, concrete or the like. The cementitious material 18 itself can form an exterior finish 20 of the assembly 10, or it can be utilized to secure other building elements, such as masonry 10 materials, natural or synthetic stones, or the like to the assembly 10.
The composite material 16 includes three separately-formed components including a membrane 22, a spacer material 24, and a lath 26. The membrane 22 is preferably a building paper; however, it can also be tar paper, roofing felt, polymeric house-wrap material, or any other type of weather-resistive sheet material.
The 15 membrane 22 can be a single layer or multilayer membrane and more than one membranes 22 can be utilized. For instance, several like or different membranes can be secured together to form a multilayer membrane.
The membrane 22 has opposite faces, 28 and 30, and is sandwiched between the spacer material 24 and lath 26. Preferably, the spacer material 24 is bonded to one 20 face 28 of the membrane 22, while the lath 26 is bonded to the other face 30. As an example, the spacer material 24 and lath 26 can be bonded to the membrane 22 with adhesives or via thernial, ultrasonic, mechanical, chemical or like bonding techniques.
The composite material 16 can be provided in a spiral roll 32 as illustrated in FIG. 3 or in sheets 34 as illustrated in FIG. 4.
25 The lath 26 is preferably a plastic or metal mesh material that provides a base for the application of cementitious material. Thus, after the composite building material 16 is fastened to the inner structural component, 12 or 14, with the lath 26 facing outwardly, cementitious material 18 can be applied directly on the lath 26 to form an exterior finish 20 of the assembly 10.
The spacer material 24 provides open ventilation and drainage passages 36 adjacent the inner sheathing member 12 and/or studs 14. Thus, any condensation, liquid moisture or moisture vapor that collects between the exterior finish 20 and inner structural components, 12 or 14, will be directed downwardly and outwardly of 5 the assembly 10 or will be evaporated and removed via air flow through the passages 36. To achieve this purpose, the spacer material 24 can be a corrugated material as illustrated in the drawings or can be provided as an openwork mat, a plastic sheet material thermoformed or vacuum-stamped with outwardly projecting spacer elements from one or both faces thereof, or a plurality of separate spacer discs or elements 10 secured to the membrane 22. For example, a corrugated plastic sheet of material 38 with perforations 40 provides the spacer material 24 in the assembly 10 of FIG. 1. In contrast, the spacer material 24 in FIG. lA is provided as a corrugated web 42 of randomly convoluted polymeric filaments.
If inner sheathing members 12 are utilized in the assembly 10, the members 12 15 are secured with nails 44 or like fasteners to posts 14. As an option, a weather-resistive membrane (not shown) can be applied directly over the inner sheathing member 12. Alternatively, the inner sheathing members 12 can remain exposed.
If utilized, the weather-resistive membrane on the sheathing members 12 can be a building paper, tar paper, roofing felt or a polymeric house-wrap material that permits 20 moisture vapor to exit outwardly therethrough.
The composite building material 16 can then be fastened to the inner sheathing members 12 with fasteners 46. Alternatively, if open stud construction is utilized, the composite building material 16 is fastened directly to the studs 14. The fasteners 46 can be nails with relatively large nailheads, nails utilized with relatively-large 25 diameter washers, or staples. Thus, all layers 22, 24 and 26 of the composite building material 16 are connected simultaneously with the fastener 46 to the inner sheathing member 12, or studs 14. If the composite building material 16 is provided in a spiral roll, it is unrolled before or as the fasteners 46 are applied. The composite building material 16 can also be provided and applied in sheet form.
After the composite building material 16 is fastened to and covers the imier sheathing member 12 or open studs, cementitious material 18, such as stucco, is applied with a trowel or like tool to the outwardly facing lath 26 of the composite building material 16. The membrane 22 prevents ingress of the cementitious material 18 into the passages 36 provided by the spacer material 24.
While preferred composite building materials, wall assemblies, and methods of assembling wall structures have been described in detail, various modifications, alterations, and changes may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
If inner sheathing members 12 are utilized in the assembly 10, the members 12 15 are secured with nails 44 or like fasteners to posts 14. As an option, a weather-resistive membrane (not shown) can be applied directly over the inner sheathing member 12. Alternatively, the inner sheathing members 12 can remain exposed.
If utilized, the weather-resistive membrane on the sheathing members 12 can be a building paper, tar paper, roofing felt or a polymeric house-wrap material that permits 20 moisture vapor to exit outwardly therethrough.
The composite building material 16 can then be fastened to the inner sheathing members 12 with fasteners 46. Alternatively, if open stud construction is utilized, the composite building material 16 is fastened directly to the studs 14. The fasteners 46 can be nails with relatively large nailheads, nails utilized with relatively-large 25 diameter washers, or staples. Thus, all layers 22, 24 and 26 of the composite building material 16 are connected simultaneously with the fastener 46 to the inner sheathing member 12, or studs 14. If the composite building material 16 is provided in a spiral roll, it is unrolled before or as the fasteners 46 are applied. The composite building material 16 can also be provided and applied in sheet form.
After the composite building material 16 is fastened to and covers the imier sheathing member 12 or open studs, cementitious material 18, such as stucco, is applied with a trowel or like tool to the outwardly facing lath 26 of the composite building material 16. The membrane 22 prevents ingress of the cementitious material 18 into the passages 36 provided by the spacer material 24.
While preferred composite building materials, wall assemblies, and methods of assembling wall structures have been described in detail, various modifications, alterations, and changes may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
