LathNet™ | The Patented Drainage Plane and Metal Lath System for Adhered Masonry Veneers

2015 Architectural Record Products Winner

LathNet is a metal lath and drainage plane system that provides a continuous drainage plane between the lath and weather resistant barrier.

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″

• Faster installation and fewer wall penetrations than installing a drainage plane and lath separately
• Combines proven components in an engineered and tested system
• Factory assembly ensures consistent quality
• Clearly shows 1” minimum lath overlap to comply with ASTM C847
• Promotes full lath encapsulation without clogging the drainage plane
