le R402.1.1 Footnotes � 51: 1 foot .= 304.8 rnm, ci .= cc iuous insulation, int .= intermediate fram...;. ' R-values are minimums. U-factors and SHGC are maximums. When insulation is installed in a cavity whith is less than the lahel or design thickness of the insulation, the compressed R-value of the insulation irom Appendix Table A101.4 shall not be less than ihe R-value specified in the table. b The fenestration U-factor column exdudes skylights. The SHGC column applies t� all glazed fenestration. Exception: Skylights may be excluded from glazed fenestration SHGC requirements in Climate Zones 1 through 3 where the SHGC for suth skylights does not exceed 030. `"10/15/21.+T0" means R-10 continuous insulation on the exterior of the wall, or R-15 on the continuous 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 permitled to be met with R-13 cavity :�sulation on the interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the wall. "10/13" means R-10 continuous insulation on the interior or exterior of the home or R- ]3 cavity insulation at the interior of the basemen. wall. "TB" means thermal break between floor slab and basemen[ wall. I I" R-10 continuous insulation is required under heated slab on grade floors. Sec R402.Z.9.1. `There are no SHGC mquirements in the Marine Zone. � Dasement wall insulation is not required in warm-humid locations as de(ined by Pigure R301.1 and Table R301.1. ° Rescrved. �' 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 structural sheathing covers 40 percent or less of the exterior, tontinuous insulation R-value shall be permitled to be rrduced by no more than R-3 in the locations where structural ;heathing is used to maintain a consistent total sheathing thictiness. ' Thc second R-valur applics when more than half the insulation is on lhe interior of the mass wall. ' For single rafter or joist-vaulted ccilings, the insulation may bc reduced [o R-38. k Int. (intermediate framing) denotes standard framing 1G inches on center with headers insulated with a of R-10 insulation. log and solid timber wa!Is with a minimum average thickness of ?. i inches are exempt from this insulation equiremenl.
