    adhesive; cement plaster; casing bead; cold-rolled channel furring; control joint; corner reinforcement; drainage screed; expansion joint; fastener; furring accessory; lathing accessory; nail; screw; staple; weep screed;;


    Rationale: Current Table 3 minimum fastener lengths indicated are for stucco assemblies without additional components such as foam plastic insulation and drainage mats. Table 3 does not state requirements for the additional fastener lengths needed to accommodate these additional components. 1.Adds new Footnote A wording: When additional components such as CI and drainmat are included in the stucco assembly, proposed additional wording is broad enough to require use of either prescriptive fasteners compliant with the local code (such as in IBC Chapter 26 CI fastener tables), or engineering evaluation and approval of Authority Having Jursisdiction.
