Instructions: This single-family project will use the requirements of the Prescriptive Path below and
incorporate the minimum values listed. Based on the size of the structure, the appropriate number of
additional credits are checked as chosen by the permit applicant.

a
R-values are minimums.U-factors and SHGC are maximums. When insulation is installed in a cavity that is less
than the label or design thickness of the insulation, the compressed R-value of the insulation from Appendix
Table A101.4 shall not be less than the R-value specified in the table.
b The fenestration U-factor column excludes skylights.
c
"10/15/21 +5TB" means R-10 continuous insulation on the exterior of the wall, or R-15 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 +5TB" shall be permitted to be met with R-13 cavity insulation on
the interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the wall. "5TB"
means R-5 thermal break between floor slab and basement wall.
g For log structures developed in compliance with Standard ICC 400, log walls shall meet the requirements for
climate zone 5 of ICC 400.
h
Int. (intermediate framing) denotes framing and insulation as described in Section A103.2.2 including standard
framing 16 inches on center, 78% of the wall cavity insulated and headers insulated with a minimum of R-10
insulation.
These requirements apply to all IRC building types, including detached one- and two-family
dwellings and multiple single-family dwellings (townhouses).
Provide all information from the following tables as building permit drawings: Table R402.1 - Insulation and
Fenestration Requirements by Component, Table R406.2 - Fuel Normalization Credits and 406.3 - Energy Credits.

R-7.5 continuous insulation installed over an existing slab is deemed to be equivalent to the required perimeter
slab insulation when applied to existing slabs complying with Section R503.1.1. If foam plastic is used, it shall
meet the requirements for thermal barriers protecting foam plastics.
For single rafter- or joist-vaulted ceilings, the insulation may be reduced to R-38 if the full insulation depth
extends over the top plate of the exterior wall.
