� Table R402.1.1 Footnotes For 51: 1 foot :304.8 mm, ci : continuous insulation, int =intermediate framing. 'R-ValUeS are minimUms. U-fa[tor5 and SHGC are maximums. W hen insulation is installed in a cavity which is less than the label or design thickness of the insulation,the compressed R-value of the insulation from Appendix Table A101.4 shall not be less than the R-value specified in the table. °The fenestration U-factor column excludes skylights.The SHGC column applies to all glazed fenestration. Exception:Skylights may be excluded from glazed fenestration SHGC requirements in Climate Zones 1 through 3 where the SHGCfor such skylights does not exceed 0.30. `"10/15/21.+TB" means R-10 continuous insulation on the eu[erior of the wall, or R-15 on the continuous insulation on the interior ofthe wall, or R-21 cavity insulation plus a thermal break between the slab and the basement wall atthe interior of the basementwall."10/15/21.+TB" shall be permitted to be met with R-13 cavity insulation onthe interior ofthe basement wall plus R-5 continuous insulation on the interior or exterior ofthe wall. "10/13" means R-10 continuous insulation on the interior or exterior ofthe home or R- 13 cavity insulation at the interior ofthe basement wall."TB" means thermal break between floor slab and basement wall. ° R-10 continuous insulation is required under heated slab ongrade floors.5ee R402.2.9.1. °There are no SHGC requirements inthe Marine Zone. �Basement wall insulation is not required in warm-humid locations as defined by Figure R301.1 and Table R301.1. s Reserved. ° Firstvalue 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 structural sheathing covers 40 percent or less ofthe exterior, continuous insulation R-value shall be permitted to be reduced by no more than R-3 in the locations where structural sheathing is used to maintain a consistent total sheathing thickness. 'The second R-value applies when more than half the insulation is on the interior ofthe mass wall. ' For single rafter-orjoist-vaulted ceilings,the insulation may be reduced to R-38. k Int. (intermediate framing) denotes s[andard framing 16 inches on center with headers insulated with a minimum of R-10 insulation. � Log and solid timberwalls 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 or an approved source or as specified in Section R402.1.3.
