concrete wall insulation - GreenBuildingAdvisor

Bill37| Posted in General Questions onOctober 3, 2024 12:46pmI’m renovating a home made of old concrete blocks. I’m in the insulation stage and need assistance regarding the first-floor walls; they are made of concrete blocks with 2×6 studs 1/2 inch from the concrete wall. What is the best way to insulate the walls? Do I put a vapor barrier between the concrete blocks and the 2×6 studs and add faced fiberglass batts in between the studs? Or should I not use a vapor barrier between the concrete wall and the studs and just put faced fiberglass insulation between the studs with the paper facing the drywall? The 2×6 studs are not pressure-treated. I’m in Pennsylvania, so it’s a cold climate. please see image attached Thank you!
