Faced Batts & Rolls

Faced batts and rolls are lightweight, naturally white thermal and acoustical fiber glass made of long, resilient glass fibers. In all Johns Manville faced batts and rolls, the fibers are bonded with a Formaldehyde-free™ binder, to promote better indoor air quality. The facing serves as an integral vapor retarder, reducing the potential for mold and mildew growth and making faced insulation an appropriate choice for external walls. JM faced batts and rolls come in a variety of R-values from R-11 to R-38.
