Abstract: Self-furring, welded wire lathing includes a flexible paper support material disposed substantially in a vertical plane and having horizontally spaced-apart openings cut therethrough. The openings are arranged in parallel horizontal rows, with the spacing between adjacent openings in each horizontal row defining intervening webs of support paper therebetween. A metal reinforcing grid is interwoven with the support material, and includes a regular array of horizontal and vertical wires which are welded together at their intersections, with each such weld in registry with one of the openings. The vertical wires are arranged across the front face of the support material, while the horizontal wires are arranged in two wire courses; a first horizontal wire course arranged across the front face of the support material and a second horizontal wire course arranged across the back face of the support material.
