Abstract: A welded wire lathing material for mounting stucco plaster and the like onto a building frame. This lathing material comprises intersecting transverse and primary longitudinal strands substantially located in a first plane. It also comprises secondary longitudinal strands also substantially placed in first plane and closely spaced with, some of primary longitudinal strands, thus forming longitudinal slots located at predetermined spaced intervals extending across the lathing material. The slots are wider than the shaft, but narrower than the head, of fasteners predetermined for attaching the lath to building frames. The longitudinal and transverse strands are welded together where they intersect to form a rectangular mesh approximately located in the first plane.

Abstract: A shear wall system comprises stucco fasteners consisting of an elongated first portion that is driven into a wood frame wall, and an elongated second portion that is completely embedded in a stucco wall panel. In one embodiment, the fasteners consist of an assembly having a first element that is driven into the wood frame wall, and a second annular element receiving a portion of the first element and that is embedded rigidly into the cement stucco wall. Ductile movement of the fastener components with respect to wood frame wall and the stucco wall provides energy dissipation.

Abstract: The invention relates to metal wire mesh having a plurality of longitudinal wires and a plurality of transverse wires. The longitudinal wires of the mesh are provided with shaped areas wherein the moment of inertia of said shaped areas about the neutral axis parallel to the plane of the mesh is 90 percent or less of the moment of inertia of said shaped areas about the neutral axis vertical to the plane of the mesh. This substantially reduces the problem of curvature set when metal wire mesh is rolled for packaging or transport and attempts are made to unroll prior to use.

Abstract: A vapor permeable prefabricated membrane for use in an exterior wall or party wall of a building, which has passageways formed when the membrane is in place in the wall extending from a region near a top of the wall to a bottom thereof. The passageways permit the escape of trapped moisture.
