YES YES !! You are all correct, The problem is that One Inspection Firm reads the code in a different view. Air Tight is Can only - No Trims, But I want to challange them about this ruling ( AJH ). Other Firms & Building inspectors all aprove both types. This firm feels they are correct & everybody is wrong. I am stuck with an open inspection & can not switch at this time, but others have inspected the site in respect to this issue, and find nothing wrong. Who has the final word ??
