For 51: 1 foot = 304 8 mm, ci .= coi�,.,�uous insulation, int .= intermediate framii��. ' k-values are minimums. U-(actors and SHGC are maximums. When 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 A101A shall not be less than the R-value specified in Ihe table. ° The fenestrelion U-factor mlumn exdudes skylights. The SHGC column applies to all glazed fenestration. [xception: Skylights may be exduded from glazed fenestration SHGC requiremen[s in Climate 2ones l through 3 where the 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 interior of Ihe wall, or R�21 cavity insulation plus a thermal break be[ween the slab and Ihe basement wall at the interior of the basement wall. "10/15/21.*TB" sha!I 6e permitted to bc met with R-13 caviry insulation on the interior of the oasement 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 [he home or R- 13 caviry insulation at the interior of the basement wall. "TB" means Ihermal break between floor slab and basement wall. R-10 continuous insulation is required under heated sla6 on grade floors. See R402.2.9.1. There are no SHGC requiremenis in the Marine Zone. Basement wall insulation is not reyuired in warm-humid locations as defined by Figure R307.1 and Table R301.1. � Reserved. " First value is cavity insulation, second is continuous insulation or insulated siding, so "13.+5" means R-13 cavity insula[ion plus R-5 continuous insulation or insulated siding. If structural sheatning covers 40 percent or Iess of the exterior, conunuous inwlation R-value shall be permitted ro be reduced by no more than R-3 in the locations vihere strudural sheathing is used to maintain a consis[ent total sheathing [hickness. � 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 ceilir��s, the insulation may be reduced to R-38. `Int. (intermediate framing) denotes standard framing 16 inches on center with headers insulared with a minimum of R-10 insulation. � Log and solid timber walls with a minimum average [hickness of 3.5 inches are exempt (rom this insulation requirement Table R402.1.3_Footnote ' Nonfenestration U facrors shall be obtained from measurement, calculation or an approved source or as specified in Section R402.13. il: ..• ) .- _.� I ` ., ,
