• INFORMATIVE APPENDIXE
    BUILDING ENVELOPE TABLES

    (This appendix is not part of this code. It is merely informative and does not contain requirements necessary for conformance to the code. It has not been processed according to the ANSI requirements for a code and may contain material that has not been subject to public review or a consensus process. Unresolved objectors on informative material are not offered the right to appeal at ASHRAE or ANSI.)

    The first nine tables are in I-P units, followed by nine tables in SI units. U-factors, C-factors, F-factors, and SHGC in these tables meet the requirements of Section 701.4.2.1 (7.4.2.1), although the R-values in most cases provide more insulation than is required in Section 701.4.2.1 (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 701.4.2.1 (7.4.2.1) when they meet the appropriate U-factor, C-factor, or F-factor criteria.

    2. **The insulation minimum R-value criteria in this table meet the criteria in Section 701.4.2.1 (7.4.2.1), but it is possible that some assemblies with slightly less insulation minimum R-value will also meet the criteria of Section 701.4.2.1 (7.4.2.1).

    3. a.When using the R-value compliance method for metal building roofs, a thermal spacer block is required (see ANSI/ASHRAE/IES Standard 90.1, Section 3.2).
