Table R402.1.1 Footnotes • For SI: 1 foot .= 304.8 mm, ci = mntinuous insulation, int .= intermediate framing. ' R-values are minimums. U-facmrs and SHGC are maximums. When insulation is installed in a cavity which is lessthanthe label or design thickness of the insulation,the mmpressed R-value of the insulation from Appendix Table A1014 shall not be less than the R-value specified in the table. °The fenestration U-facmr mlumn exdudes skylights.The SHGC mlumn applies to all glared fenestration. Exception: Skylights may be exduded from glared fenestration SHGC requirements in Climate Zones 1 through 3 where the SHGC for such skylights does not exceed 030. "'10/15/21+TB" means R-10 mntinuous insulation on the exterior ofthe wall, or R-15 onthe 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.+T8"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 of the wall. "10/13" means R-10 mntinuous insulation on the interior or exterior of the home or R- 13 cavity insulation atthe interiorof the basementwall. "TB" meansthermal break betweenfloorslab and basementwall. � R-10 mntinuous insulation is required under heated slab on grade floors. See R4022.91. `There are no SHGC requirements inthe MarineZone. f Basement wall insulation is not required in warm-humid locations as defined by Figure R3011 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 strucwral sheathing mvers 40 percent or less of the exterior, mntinuous insulation R-value shall be permitted to be reduced by no more than R-3 in the locations where strucwral sheathing is used to maintain a mnsistent mtal sheathing thickness. �The semnd R-value applies when more than half the insulation is on the interior of the mass wall. � For single rafter-orjoist-vaWted ceilings, the insulation may be reduced to R38. " Int �intermediate framing) denotes standard framing 161nches on center with headers insulated with a minimum of R-10 insulation. � Log and solid timber walls with a minimum average thickness of 3.5 inches are exempt from this insulation requirement. Table R402.13 Footnote ' Nonfenestration U-facmrs shall be obtained from measurement, calculation or an approved source or as specified in Section R40213.
