What is an acceptable air barrier separating showers and tubs as referenced in the 2009 IECC Section 402.4.2.2?
I live in Zone 5 (No.NV) and it has been the local custom to place unfaced batt insulation in outside walls between showers and tubs in new construction. Line item 13 of the referenced Inspection process under the 2009 IECC specifies an air barrier to be used. I'm a certified HERS Rater performing these inspections, but having much resistance to this item.
