The exterior soffit panels are identified as Hardiesoffit® (Cemsoffit®) panels and may be vented or unvented. The fiber-cement sheets comply with ASTM C1186 as Type A, Grade II, and have a flame-spread index of 0 and a smoke developed index of 5 when tested in accordance with ASTM E84. The sheets are classified as noncombustible when tested in accordance with ASTM E136. Thermal conductivity (K) and thermal resistance (R) values for the unvented products are shown in Table 2 based on ASTM C177 tests. When tested in accordance with ASTM E96, unvented products with a thickness of ¼ inch (6.4 mm) have demonstrated the permeance value given in Table 3 of this report. Soffit panels are available with either a woodgrain texture or a smooth unsanded surface. The exterior soffit products may be supplied unprimed or primed for subsequent application of a compatible primer and/or exterior-grade topcoat(s). Nominal soffit dimensions are noted in Table 1. 4.0 DESIGN AND INSTALLATION 4.1 Design: The maximum wind speeds, building heights and exposure categories applicable for Hardiesoffit® and Cemsoffit® panels are noted in Table 5. Vented soffit panels provide net free ventilation area as presented in Table 4 of this report. 4.2 Installation: Installation shall comply with this report and the manufacturer’s published installation instructions. A copy of the manufacturer’s published installation instructions this report must be available at the job site during installation. All panel edges must be supported be framing members. Panels must be attached with corrosion-resistant fasteners installed with a minimum 3/8 inch (9.5 mm) edge distance and minimum 2-inch (51 mm) clearance from corners. The panels must be installed with the long edge of the panel perpendicular to the joist framing and must be attached with fastener types, lengths, and spacings described in Table 5. Framing must include a subfascia, blocking, and/or ledger board to provide a nailing base along the dimension of the soffit. 5.0 CONDITIONS OF USE The Hardiesoffit® and Cemsoffit® exterior soffit panels described in this report comply with, or are suitable alternatives to what is specified in those codes listed in Section 1.0 of his report, subject to the following conditions: ESR-2273 | Most Widely Accepted and Trusted Page 2 of 3 5.1 The Hardiesoffit® and Cemsoffit® panels must be installed in accordance with this report and the manufacturer’s published installation instructions. In the event of a conflict between this report and the manufacturer’s published installation instructions, this report governs. 5.2 The Hardiesoffit® and Cemsoffit® soffit panel are manufactured under a quality control program with inspections by ICC-ES at the following locations: 5.2.1 Pulaski, Virginia 5.2.2 Tacoma, Washington 5.2.3 Waxahachie,Texas 6.0 EVIDENCE SUBMITTED 6.1 Data in accordance with the ICC-ES Acceptance Criteria for Fiber Cement Siding Used as Exterior Wall Siding (AC90), dated June 2012 (editorially revised September 2015). 7.0 IDENTIFICATION Hardiesoffit® and Cemsoffit® panels shall be identified by a stamp or label on the board bearing the name and address of the report holder (James Hardie Building Products), the product name (Hardiesoffit® or Cemsoffit®), and the evaluation report number (ESR-2273).
