z SP <br />table R40Z.1.1 Footnotes <br />For SI: 1 foot .=304.8 mm, ci .=continuous insulation, int .=intermediateframing. <br />a R-values are minimums. U-factors and SHGC are maximums. When insulation is installed in a cavity which is less <br />than the label or design thickness of the insulation, the compressed R-value of the insulation from Appendix Table <br />A101.4 shall not be less than the R-value specified in the table. <br />b The fenestration U-factor column excludes skylights. TheSHGC column applies to all glazed fenestration. <br />':--IO/15/21.+TB" means R-10 continuous insulation on the exterior of the wall, or R-15 on the continuous insulation <br />on the interior of the wall, or R-21 cavity insulation plus a thermal break between the slab and the basement wall at <br />the interior of the basement wall. "10/15/21.+TB" shall be permitted to be met with R-13 cavity insulation on the <br />interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the wall. "10/13" means R- <br />10 continuous insulation on the interior or exterior of the home or R-13 cavity insulation at the interior of the <br />basement wall. "TB" meansthermal break between floor slab and basement wall. <br />d R-10 continuous insulation is required under heated slab on grade floors. See 11401.2.9.1 <br />eThere are no SHGC requirements in the Marine Zone. <br />f Reserved. <br />'Reserved. <br />h Reserved. <br />'The second R-valueapplies when more than half the insuIation is on the interior of the mass walL <br />i Reserved. <br />k For single rafter - or joist -vaulted ceilings, the insulation may be reduced to R-38. <br />Reserved. <br />m Int. (intermediate framing) denotes standard framing 16 inches on center with headers insulated with a minimum <br />ofR-10 insulation. <br />Table R402.1.3 Footnote <br />I Nonfenestration U-factors shall be obtained from measurement, calculation or an approved source or as specified in <br />Section R402.1.3. <br />Permit#: <br />B1907-008 <br />Site Address: <br />2216 CHESTNUT ST <br />Owner: <br />LAIGO 1ASON R & LINDSAY F <br />Tenant: <br />[TenNamej <br />App. Date: <br />7/9/2019 <br />Proposed Use: SFR DETACHED <br />Description: ADD SECOND STORY <br />iR <br />Date:t Fire/Planning Set <br />"y <br />�red� i3 <br />2�2 <br />
