Mar 20, 2023

LathNet is a metal lath and drainage plane system that provides a continuous drainage plane between the lath and weather resistant barrier. Now available with a NEW structured strand polymer mesh that significantly increases ventilation behind the veneer.

The Masonry Advisory Council recommends that in exterior adhered masonry wall systems, a drainage mat be installed to drain any water that has penetrated to the flashing. A galvanized expanded metal lath, or diamond mesh, should be attached atop the drainage mat.

Features

• Factory-assembled combination of mesh drainage plane and metal lath
• Metal lath: Self-furring 2.5 lb. G-60 galvanized expanded steel.
• L: 97″ +1.5 -0 W: 27″ +/-0.375 T: 0.25″
• Drainage mesh: NEW structured strand polymer drainage mesh offers up to 5 times greater airflow to allow for better ventilation
• L: 95.5″ +/-0.5 W: 25.5″ +/- 0.25 T: 0.25″
• Shipped in banded bundles of 10 sheets

Available Options

• 3.4 lb., self-furring dimpled steel mesh
• 0.4″ (10 mm) drainage mesh thickness

Available Accessories

• Weep sill screed
• 10′ length, 26 gauge G60 galvanized steel
• Expanded corner bead
• 10′ length
• Double-V control joint
• 10′ length

Benefits

• Faster, easier installation than installing a drainage plane and lath separately
• Installs like standard metal lath, no new installation skills or tools necessary
• Combines proven components in an engineered and tested system
• Clearly shows 1” minimum lath overlap
• Promotes full lath encapsulation without clogging the drainage plane
