Table R402.1.1 Footnotes For51: 1foot .= 304.8mm, ci :mntinuousinsulation, int .= intermediateframing. ° R-values are minimums. U-factors and SHGC are maximums. When insulation is installed in a cavity which is less than the label or design thickness of the insulation, the mmpressed R-value of the insulation from Appendix Table A101.4 shal I not be less than the R-value specified in the table. °The fenestration U-factor mlumn exdudes skylights.The SHGC mlumn applies to all glazed fenestration. &ception: Skylights may be exduded from glazed fenestration SHGC requirements in Qimate Zones 1 through 3 where the SHGC forsuch skylights does not exceed 030. "'10/15/21+T6" means R-10 mntinuous insulation on the exteriorofthe wall, or R-15 on the mntinuous insulation on the interior of the wall,or R-21 cavity insulation plus a thermal break between the slab and the basement wall at the interior of the basement wall. "10/15/21+T6" shall be permitted to be met with R-13 cavity insulation on the interior of the basement wall plus R-5 mntinuous insulation on the interior or exterior ofthe wall. "10/13" means R-10 mntinuous insulation on the interiororexteriorofthe home or R- 13 cavity insulation at the interior of the basement wall. "TB" means thermal break between floor slab and basementwall. � R-10 mntinuous insulation is required under heated slab on grade floors. See R4021.9.1. eThere are no SHGC requirements in the Marine Zone. f Basement wall insulation is not required in warm-humid locations as defined by Figure R301.1 and Table R301.1. g Reserved. ° First value is cavity insulation, semnd is mntinuous insulation or insulated siding, so "13.+5" means R-13 cavity insulation plus R-5 mntinuous insulation or insulated siding. If structural sheathing mvers 40 percent or less of the exterior, mntinuous insulation R-value shall be permitted to be reduced by no more than R3 in the locations where structural sheathing is used to maintain a mnsistenttotal sheathing thickness. �The semnd R-value applies when more than half the insulation is on the interior of the mass wall. � Forsingle rafter-orjoist-vaulted ceilings, the insulation may be reduced to R-38. " Int. (intermediate framing) denotes standard framing lfi inches on center with headers insulated with a minimum of R40 insulation. � Log and solid timber walls with a minimum average thickness of 3.5 inches are exempt from this insulation requirement. Table R402.1.3 Footnote ' Nonfenestration U-factors shall be obtained from measurement, calculation oran approved source oras specified in Section R402.13.
