Johns Manville Sound-SHIELD® batts are lightweight, sound-absorbent batts made to ﬁt standard wood frame or steel stud construction.
JM Sound-SHIELD batts are lightweight, sound-absorbent insulations made of long, resilient glass fibers. The unfaced fiberglass batts are made to fit standard spacing and thickness of steel stud construction in commercial and institutional buildings. JM Sound-SHIELD batts provide maximum sound control effectiveness by completely filling the cavity wall. These sound control batts are compatible with wood or steel studs in walls and are also used in floor/ceiling assemblies. JM sound control batts can effectively increase STC ratings by 8 to 10 points in certain assemblies. Use of resilient channels can make wall assemblies even more efficient.
