sections and the principal plane of the lath mesh the barrier layer material has apertures that coincide with the intersections only at the bent sections to enable mesh size reduction without compromising the barrier layer but still allow the fabrication of the lath the lath provides good embedment in the stucco reduces cracking and wastage of stucco while remaining easy to work with application_number US 93582104 A description throughout the following description specific details are set forth in order to provide a more thorough understanding of the invention however the invention may be practiced without some of these particulars in other instances well known elements have not been shown or described in detail to avoid unnecessarily obscuring the invention accordingly the specification and drawings are to be regarded in an illustrative rather than a restrictive sense referring to fig2 and fig3 lath 10 according to a currently preferred embodiment of the invention comprises a plurality of first generally parallel longitudinal wires 12 which intersect with a plurality of generally parallel transverse wires 14 wires 12 lie substantially in a first plane pi best appreciated by reference to fig3 similarly wires 14 lie substantially in plane pi save that wires 14 are bent out of plane p 1 at truss locations 15 wires 12 and 14 are welded together at their intersections 11 wires 12 and 14 preferably extend generally perpendicularly to one another the spacing of wires 12 and 14 can be such that square or rectangular grid openings are created a set of second longitudinal wires 13 is also welded to transverse wires 14 as described below wires 12 13 and 14 may be made of any suitable materials such as steel aluminum or the like if made of steel the wires are preferably galvanized wires 12 13 and.
