Self Furred Lath

TILATH – DIAMOND MESH OR SELF-FURRED LATH is diamond mesh lath, regular or self-furred, to which offset asphalt saturated kraft building paper has been applied. The grade D paper typically used is water-resistant, yet highly vapor permeable, and meets federal specification UU-B-790a, type 1, grade D, style 2. Tilath reduces moisture penetration while allowing for the dissipation of moisture vapor from within the structure. Foundation weep screed at the bottom of all framed walls aids in the elimination of moisture that might reach the surface of the building paper.

3/8 Inch Rib Lath

3/8” RIB LATH (HIGH RIB)
Due to its heavy construction with seven longitudinal ribs, each 3/8” deep and eight small flat ribs it is used almost exclusively for ceiling and soffit applications. The herringbone mesh pattern allows excellent keying of the stucco to the lath for horizontal or ceiling installations spanning up to 24” o.c. Rib lath is not generally recommended for vertical or wall installations.

Spray 3/8 Inch Rib Lath

Spray lath is used primarily on the West coast, where stucco is spray applied to the surface of the lath to build stucco thickness. Rib Lath is often attached directly to the vertical framing members without a solid board substrate included. Spray products are categorized as follows:

Spray Rib Lath – High (3/8”) Rib is a more rigid lath product than Diamond Mesh, and like Spray Lath, has strips of kraft paper attached between the ribs. The additional rigidity is well suited for horizontal applications such as soffits. The High Rib allows for (up to) 24” spans.
