Climate Zone 3-strategy for venting or not venting a small attic kneewall space?
Climate Zone 3. I have a Finished Room of the Garage (FROG) with kneewalls that has wood paneling on the finished side. The paneling started to show signs of moisture issues. I removed the paneling and found no mold in the space but elevated moisture (22%). R13 insulation with vapor retarder on warm on winter side is present. There is not much room between the kneewall and the exterior wall of the reverse A. Essentially a double 2×4 wall is it. This area is closed off to the rest of the vented attic due to the sloped ceiling of the finished room being tight to the roof rafters (insulation present but not room to vent to ridge vent). There is one 16×8 soffit vent in the closed off kneewall space. The question is…should I close of the soffit vent and pack the space with insulation? Or add a couple more soffit vents to hopefully better circulate air? In the humid climate if feel closing it off is the better solution since its such a small space but unsure. Right not it seems to just be letting hot humid air in through the one soffit vent.
