Both processes proved effective however, the United States found that their engineering did a better job of holding up to the rugged and extreme temperature changes that took place during Westward Expansion. In North America (the United States and Canada), the laths were typically sawn however, the United Kingdom usually used split or riven hardwood laths. Metal laths were usually provided in bigger sheets. Then, the laths were spaced about a half of an inch apart. A wooden lath was usually about one inch thick and four feet long. The laths were tacked in place at the studs. In order to use this process, the wall or ceiling was built using either wood or metal strips, which went into the lath. Eventually, lath and plaster fell out of favor as drywall became more popular. There are countless builders that leaned on lath and plaster for many years because it was strong, soundproof, and able to resist fires. Then, the entire structure was coated in plaster, which provided the structure with its integrity. The structure uses narrow strips of wood, called laths, which were nailed horizontally across the joists or wall studs. Lath and plaster is a traditional building process that was once used as the standard to finish ceilings and interior dividing walls. Paper backed lath is often used in this type of application as a bond breaker.First, it is important to learn more about lath and plaster. Self-Furred Metal Lath is secured to masonry surfaces with hardened concrete nails and power driven fasteners at the furring dimples Self furring rib lath used over solid surfaces shall be furred approximately ¼ inch away from the wall to allow for the proper stucco keying behind Slope protection, earth embankment engineering, etc.įastener placement should be arranged for ideal furring Landscape sculpture, and other special engineering Plaster and cement in the construction of buildings Sidings, partitions and ceilings to eliminate channels Rib lathing products are now popularly used in following: Optimization of process,increase the shear inerface. Light weight, easy to transport and install Good mechanical performance, with less lateral pressure Ĭoncrete pouring process is easy seen and under control Metal ribbed lath remains strong in bonding and shearing and other forming The mesh lath becomes embedded easily with the concrete in buildings Minimum stress cracks by maintaining consistent material depth. Square ends and smooth parallel edges on the sides for fast and easy handling Rigid and flat sheets, bendable for box and contour design The uniform diamond opening and large open area provide a superior substrate for bonding of cementitious fireproof materials For over 80 years, throughout the world.ĭiamond metal lathing is ideal for fireproofing structure constructions: High ribbed metal lath is primarily used in construction joint applications but it is also used to form wall, beam & column surfaces and slabs soffits, where the formed surface will not be seen. The products are made from a single plate of steel. High rib mesh products are a derivative of the "wings" used in the patented Kahn System of reinforced concrete, invented by Julius Kahn in 1903. The steel sheet form would be embedded with plaster or cement directly and would flow into the lath surface to attach itself to the reinforcing steel and harden to secure the material into the steel. Metal rib lath makes idea plaster base and reinforcement for all types of walls,ceilings, partitions and fireproofing of steel beam,and columns. Ribbed mesh lath is a high tensile metal lath stiffened by the longitudinal V ribs.
