When designing and specifying, check the appropriate reference for complete details on a particular assembly. A change in details may affect the fire resistance of the assembly. 1. LOAD -BEARING EXTERIOR WALL SYSTEM Generic, nonproprietary assembly based on GA File No. WP8105 in Gypsum Association (G.A.) Fire Resistance Design Manual; applicable references in 1997 Uniform Building Code (Table No. 7-B), and 1997 Standard Building Code (Sec. 701.5.2) (b) APA Rated Siding Exterior 5/8' Type X gypsum sheathing Mineral wool or glass fiber insulation (optional) 5/8' Type X gypsum wallboard Min. 2x4 studs @ 16' or 24' o.c. 2. LOAD -BEARING EXTERIOR WALL SYSTEM Generic, nonproprietary assembly based on combining Item No. 18-1.2 and 18-1.3 and Footnote 17 or Table 7-B in the 7997 Uniform Building Code. Also see Sec. II-D of ICBO Evaluation Service Inc. Report No. 1952.

(a) Wall systems exposed to fire an both exterior and interior faces, except where indicated by "Fire Side" (tested from interior face only). (b) For a two-hour load -bearing exterior wall of similar construction, see GA File No. WP 8415 (requires two layers of 5/8' Type X gypsum sheathing on exterior side of wall, and two layers of 5/8' Type X gypsum wallboard on interior side). (c) See APA Design Construction Guide: Residential and Commercial (Form E30) for installation recommendations when stuxo exterior finish is used. Building paper is required where sWao is applied over structural wood panel sheathing (check local building code and applicator for specific require- ments). Uniform Building Code requires two layers of waterproof building paper (per Federal specification UU-B-790. Type 1. Grade D) over wood - based sheathing. FIRE SIDE (d) Footnote 17 of Table No. 7-13 in the 1997 Uniform Building Code permits Installation of mod structural panel sheathing directly over studs, beneath Fire protective membrane, for added racking resistance or shear wall applications, in certain generic, nonpropnetary fire -rated wall assemblies. Also see ICBO Evaluation Service Inc. Report No. 1952 for wood structural panels used for wall sheathing in these assemblies. (a) For proprietary names see latest U.L.
