Spec sheets

  • Hardie® Soffit Panels — Specification Sheet 06 (Available Sizes table, performance properties) — James Hardie Building Products, Inc., syndicated via BuildSite · dated 2024-02-01 · PDF
    Two pages. Corroborates the evaluation report at 1/4 inch and carries the dimensional tolerance (thickness ± 0.04 in, ASTM C1185). Its widths (12, 16, 24, 48) and lengths (96, 144) are OPTION SETS and panelWidthIn / panelLengthIn are stated-only tiers, so neither was written — see the tier gap in the lane log.

Evaluation reports

  • ICC-ES ESR-2273 — HardieSoffit® and CemSoffit® Exterior Soffit Panel — ICC Evaluation Service, LLC · PDF
    Seven pages. THE ONLY CODE-EVALUATION REPORT IN THE EAVES CATEGORY, and therefore the only eaves record where source precedence has a top tier to fire from. Section 3.0 states the panel thickness in prose and Tables 2 and 3 head a column PRODUCT THICKNESS (inch) — neither qualified as nominal. Table 1 IS headed STANDARD NOMINAL SOFFIT DIMENSIONS and its widths and lengths were not ingested for that reason.
