MR Faced Batt insulation was specifically created to control moisture. The lightweight thermal and acoustical fiberglass insulation is made of long, resilient glass fibers bonded with an acrylic thermosetting binder. The facing reportedly serves as an integral vapor retarder and is additionally protected against potential fungi growth. MR Faced Batts are available in a variety of R-values up to R-38, and in pre-cut batts to fit standard wall cavities. www.jm.com
