a.R-values are minimums-1,Lfactors and SF1GC are tnasimums.When insulation is installed in a cavity which is less than the Zabel or design
thickness of the
insulation,the installed R-value of the insulation shall not be Tess than the R-value specified in the table.
b.The fenestration U-Factor column excludes sl yhghts The Sl1GC column applies to all glazed fenestration.Cxcepnoty Skylights rna% be
excluded from glazed
fenestration S1IGC requirements in climate zones I through 3 where the SI-IGC for such skylights does not exceed 0,30.
e."1 i/19'means R-15 continuous insulation on the interior or exterior of the home or R-19 cavity insulation at the interior of tlic basement wall.
