Q: What Johns Manville products provide the best sound control?
A: The best products for use in minimizing sound transmission through walls, floors and ceilings are Johns Manville's thermal and acoustical fiber glass batts. Another option is the use of Johns Manville's Climate Pro® fiber glass insulation installed as a Blow-in-Blanket® System (BIBS). Both products, when installed correctly, will dampen the airborne sound within the cavity reducing the amount of sound transmitted through the partition. For optimal performance the fiber glass insulation should completely fill the partition cavity.
The best products for use in applications where sound absorption within the room is required are Johns Manville's unfaced, Black matt faced and Coated Black Insul-SHIELD
® fiber glass board products. Unfaced and Black matt faced Insul-SHIELD® are offered in a variety of densities and thicknesses.
