Abstract
A self-furring wire lath has stiffening trusses. In a preferred embodiment the lath comprises a grid of intersecting transverse and longitudinal wires welded at their intersections. Stiffening trusses are formed at bent sections in the transverse wires by first longitudinal wires affixed at the shoulders of the bent sections and second longitudinal wires affixed on the bent sections. A barrier layer is disposed between the first and second longitudinal wires. A building paper backing may be affixed to the barrier layer. The lath reduces cracking and wastage of stucco while remaining easy to work with.
Claims3
A welded wire lath comprising:
- a) a plurality of generally parallel transverse wires lying primarily in a first plane and each departing from the first plane in a plurality of spaced-apart bent sections, each bent section defined between first and second shoulder regions;
- b) a plurality of generally parallel first longitudinal wires lying generally in the first plane and intersecting with and attached to the transverse wires, the first longitudinal wires including, for each of the plurality of bent sections, a pair of longitudinal wires, one of the pair of longitudinal wires attached to each of the transverse wires in a first one of the shoulder regions corresponding to the bent section and another one of the pair of longitudinal wires attached to each of the transverse wires in a second one of the shoulder regions corresponding to the bent section;
- c) a plurality of generally parallel second longitudinal wires lying generally in a second plane parallel to and spaced apart from the first plane, the second longitudinal wires attached to the bent sections of the transverse wires,
- (d) a barrier layer disposed between the first and second planes;
- and
- c) a plurality of spaced apart furring spacers on the transverse wires.
