Designed for use with stucco, thin brick, stone and other types of adhered masonry

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.


  • 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


  • 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
  • Drainage mesh provides an effective mortar barrier to prevent bridging
  • Continuous drainage plane allows rapid, unrestricted moisture flow to the weep holes
  • Allows unrestricted air flow behind the lath to help promote drying
  • Assembled in the USA from 100% USA-made materials
