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.
