💡 What is the correct installation method for R thirty unfaced fiberglass batts inside open floor cavities to stop cold air leaks? You simply cut the panels slightly oversized and press them straight into the wood framing where they stay securely wedged without sliding around. It is pretty handy when you are rushing through a basement upgrade on a weekend. - Press the stiff wool strips firmly between the joists so they fill the entire void without compression or gaps around the edges - Leave a small clearance near electrical boxes and plumbing penetrations so the material never blocks necessary airflow paths - Align the cut edges flush against blocking boards to maintain continuous thermal layering across wide structural spans
