# A1.1 Precalculated Assembly U-Factors, C-Factors, F-Factors, or Heat Capacities

JUMP TO FULL CODE CHAPTER

*U-factors, C-factors, F-factors*, and *heat capacities* for typical *construction* assemblies are included in Sections A2 through A8. These values shall be used for all calculations unless otherwise allowed by Section A1.2. Interpolation between values in a particular table in Normative Appendix A is allowed for rated *R-values* of insulation, including insulated sheathing. Extrapolation beyond values in a table in Normative Appendix A is not allowed.
