Base Wall System 1 and 2(See Note 2).
3. Full wall stud cavity depth or less of Corbond III CC SPF applied using exterior
gypsum sheathing of Base Wall System 3 as the substrate and covering the width
of the cavity ad the inside of the steel wall stud framing flange.
4. Fiberglass batt insulation(faced or unfaced)
5. Mineral wool insulation(faced or unfaced)
6. Hybrid Systems:spray foam and/or fiberglass insulation or mineral wool insulation
(flash and bat insulation systems)
Exterior Sheathing 1. None(for Base Wall Systems 1 or 2 above)
(Use either 1, 2 or 3) 2. %-inch thick glass mat exterior gypsum sheathing complying with ASTM C1177
(for Base Wall System 3 above)
3. 5/8-inch thick Type X exterior gypsum sheathing(for Base Wall System 3 above)

2. Stucco— Minimum %-inch thick, exterior cement plaster and lath. A secondary
water-resistive barrier(WRB)can be installed between the exterior insulation and
the lath. The secondary WRB shall not be full-coverage asphalt or butyl-based
self-adhered membranes.
3. Minimum 2-inch thick natural stone(granite, limestone, marble, sandstone). Any
standard non-open jointed installation technique can be used.
4. Minimum 1%-inch thick concrete masonry unit (CMU), precast concrete, or
artificial cast stone. Any standard non-open jointed installation technique can be
used.
5. Minimum 1'/,-inch thick Terra Cotta non-opened jointed. Any standard non-open
jointed installation technique can be used.
Window Closure Minimum 1-gauge steel flashing, or equivalent
