    INFORMATIVE APPENDIX E
    BUILDING ENVELOPE TABLES

    The first eight tables are in I-P units, followed by eight tables in SI units. U-factors, C-factors, F-factors, and SHGC in these tables meet the requirements of Section 7.4.2.1, although the R-values in most cases provide more insulation than is required in Section 7.4.2.1. These R-values represent common assemblies in building construction. Assemblies with lower R-values are allowed to be used the meet the criteria of Section 7.4.2.1 when they meet the appropriate U-factor, Cfactor, or F-factor criteria.
