For SI: 1 foot .= 304.& mm, ci .= conunuous insula;ion, int .= intermediate framing. ' R-values are minimums. U•factors and SHGC are maximums. �Vhen insuladon is installed in a cavity which is less than the label o� design thicknr.ss of the insulation, the compressed ,.-value of the insulation from Appendix Table A101.a shall not be less than the R-valuc specified in the tab�e. ° The fenestration U-factor column excl�des skylights. The SHGC column applies to all glazed fenestration. [xception: Skylights may be excluded from glazed fenestration SHGC requirements in Climate Zones 1 through 3 where the SHGC for such sK,:ights does not exceed 0.30. `"10/15/21.+TB" means R-10 continuous insulation on the exterior of the wall, or R-15 on the con[inuous insulation on the interior o( the wall, or R-21 cavitv insulation pius a thermal break between the slab and the basement wall at the interior of the basement wall. "10/15/2].+TB" shall be permitted to be met with R-13 cavity insulation on the interior of the basement �vail pius R-5 continuous insulation on the interior or exterior of the wall. "10/13" means R-10 continuous insulation on the interior or extericr of the home or R- l3 cavity insulation at the interior of the basement wall. "TB" means thermal break between fioor slab and basement wall. ° R-10 continuous insulation is required under heated slab on grade floors. See R402.2.9.1. � There are no SHGC requirements in the Marine Zone. � Basement wall insulation is not required in warm-humid locations as defined by Figure R301.1 and Table R301.1. e Reserved. " First value is cavity insulation, second is continuous insvlation or insulated siding, so "13.+5" means R-13 caviry in.;ula.ion pius R-5 continuous insulation or insulated siding. If sVuctural sheathing covers 40 percent or less of the exterior, continuous insulation R-value shall be pe;��utted to �e reduced by no more than R-3 in the locations where struttural sheathing is used to maintain a consistent total sheathmg thickness. ' The second R-value applies when more than half ihe insulation is on the interior of the mass wall. ' For single rafter- or joist-vaulted ceilings, the insulation may be reduced to R•38. '' Int. (intermediate framing) denotes standar�'• framing 16 inches on center with h��aders insulated with a minimum of R-10 insulation. � Log and solid timber walls with a minimum averege thickness of 3.5 inches are exempt from this insulation requirement. Non(enestration U-factors shall be obtained from measurement, cakulation or an approved source or as specified in Section R402.1.3.
