The batts are compatible with wood or steel studs in ceiling and walls. The sound control batts can effectively increase STC ratings by 8 to 10 points. Use of resilient channels can make wall assemblies even more efficient by increasing STC values by as much as 4 to 5 points depending on the construction: Wood frame construction – residential homes and light commercial buildings Metal frame construction – commercial buildings Manufactured homes – modular or manufactured housing Engineered wood construction – assemblies framed with 305 mm to 488 mm on-center cavities, wide-spaced wood trusses or I-joists Suspended ceiling systems – sized to fit above 0.61m x 1.22m ceiling panels Interior wall sound control – interior walls, floor and ceiling assemblies
