J-Weep Low-Back is nail, screw, or staple-attached to the frame or sheathing, then foam insulation, cement board or metal lath can be installed over it. In any case, the protruding ridge of the metal must extend beyond the plane of overlaid materials to serve as a ground for the stucco or E.I.F.S. application. Installed in conjunction with 1" rigid insulation associated with one-coat plaster stucco systems, the 1-3/8" ground provides proper depth for plaster keying. The 2” (Nominal) J-Weep has an attachment flange that measures 1-7/8”. Galvanized for corrosion protection, it also is available with weep holes.
2" (Nominal) J-Weep should not be used as a foundation weep screed for three-coat stucco applications. This casing or plaster stop bead should only be used on approved one-coat systems.
The International Building Code (IBC)* requires that all weep screeds have a 3-1/2" nailing flange, weep holes and a minimum thickness of 26-gauge steel. This product does not conform to code-required work if used as a foundation weep.
