a, R-values are minimums. U-factors and SHGC are maximums. R-19 shall be permitted to be compressed into a 2 x 6 cavity.
b. The fenestration U-factor column excludes skylights. The SHGC column applies to all glazed fenestration.
C, R-5 shall be added to the required slab edge R-values for heated slabs.
d. The total R-value may be achieved with a combination of cavity insulation and insulating sheathing that covers 100%of the exterior
wall.
e„ The wall insulation may be the sum of the two values where the first value is the cavity insulation and the second value is insulating
sheathing. The combination of cavity insulation plus insulating sheathing may be used where structural sheathing covers not more
than 25%of the exterior wall area and insulating sheathing is not required where structural sheathing is used. If structural sheathing
covers more than 25%of exterior wall area then the wall insulation requirement may only be satisfied with the single insulation value.
