When insulation is installed in a cavity which is less than the la6el or design thickness of the insulation,the compressed R-value of the insulation from Appendix Ta61e AlO1A shall not 6e lessthan the R-value specified in the ta61e. °The fenestration LLfacmr column excludes skylights.The SHGC column applies to all glazed fenestration. Exception:Skylights may 6e excluded from glazed fenestration SHGC requirements in Qimate Zones 1 through 3 wherethe SHGC for such skylights does not exceed 030. `"10/15/21+T8" means R-10 continuous insulation on the exterior of the wall, or R-15 on the continuous insulation on the interiorof the wall, or R-21 cavity insulation plus a thermal 6reak 6etween the sla6 and the 6asement wall at the interior of the 6asementwall. "10/15/21.+T8" shall 6e permitted to 6e met with R-13 cavity insulation on the interior of the 6asement wall pWs R-5 continuous insulation on the interior or exterio rof the wall.'YO/13"means R-10 continuous insulation o n the interior or ewterior of the home or R- 13 cavity insulation at the interiorof the 6asement walL "Te" means thermal 6reak 6etween floor sla6 and 6asement wall. ° R-10 continuous insulation is required under heated sla6 on grade floors.5ee R4022.91. `There are no SHGC requirements in the Marine Zone. �easement wall insulation is not required in warm-humid locations as defined 6y Figure R301.1 and Ta61e R301.1. g Reserved. ° First value is cavity insulation, second is continuous insulation or insulated siding, so "13.+5" means R-13 cavity insulation plus R-5 continuous insulation or insulated siding. If struc[ural sheathing covers 40 percent or less of the exterior,continuous insulation R-value shall 6e permitted to 6e reduced 6y no more than R3 in the locations where strucmral sheathing is used to maintain a consistent mtal sheathing thickness. 'The second R-value applies when more than half the insulation is on the interior of the mass wall. ' For single rafter or joist-vaulted ceilings,the insulation may 6e reduced to R38. � Int �intermediate framing)denotes standard framing 16 inches on center with headers insulated with a minimum of R-10 insulation. � Log and solid tim6er walls with a minimum average thickness of 3.5 inches are exempt from this insulation requirement. Ta61e R402.1.3 Footnote ' Nonfenestration U-fac[ors shall 6e o6tained from measurement,calculation or an approved source or as specified in Sec[ion R402.13.
