Reply to comment by hoppyending in Add additional insulation to walkout basement wall cavity. Good idea? Bad idea? by hoppyending

The issue they are pointing out is that the air gap in the wall is connected to the concealed space in the floor assembly. If you fill the studs with insulation, you are excepted from the fireblocking requirement.

Otherwise, you can block the space between the framing with lumber or plywood or drywall.

Yeah. I understand what they were saying now. In my jurisdiction Sheetrock is an acceptable fire block, so there’s nothing wrong with my “framing”. I haven’t even ordered any drywall yet, so that’s why that space is open right now.
