Sometimes called, “Mid-Wall Weep Screed”, it performs as an un-punched weep screed allowing excess moisture to escape the back of a stucco membrane. This screed also performs as an expansion (control) joint with twin grounds. It is installed where a framed stucco surface meets a masonry (concrete block) stucco surface. This condition is common between floors on 2-story homes and at the base of a gable receiving stucco. The 780-780 has a solid bottom flange for full framed construction.
The un-punched flange above must be installed extending at least one inch below the framing/ concrete joint. The weather barrier and lath should be installed over the solid upper flange to direct water to the foundation weep screed. The profile is manufactured with a 3½” nailing flange as required by code.
Locally, 7/8” thick stucco is the minimum required over wood/lath and 5/8” Stucco thickness is the minimum over Masonry Block. Notice that the Mid-Band Weep Screed transitions from 7/8” to 5/8” to accommodate these different specifications.
