For effective management of heat flow and unwanted noise, Johns Manville Unfaced batts provide heat control from the exterior while effectively controlling noise in interior walls

Johns Manville Formaldehyde-free™ Unfaced thermal and acoustical insulation offers up to RSI 7.0 (R-50), and is offered in precut batts to fit standard wall cavities. Unfaced insulation reduces sound transmission through walls, ceilings and floors, and can be used in a variety of wood frame, engineered wood and steel frame construction applications, including new construction and retrofit.

Advantages
Thermally Efficient: Effective resistance to heat transfer, with RSI/R-values up to RSI 4.9 (R-28) for wood stud and RSI 7.0 (R-50) for metal stud.
Formaldehyde-free: Will not off-gas formaldehyde in the indoor environment.
Sound Control: Reduces sound transmission through exterior and interior walls, floor and ceiling assemblies.
Fire-Resistant: Flame Spread of 10 or less and Smoke Developed of 50 or less.
Resilient Inorganic Glass: No rotting, mildew or deterioration. Also noncorrosive to pipes, wiring and metal studs.
Superior Performance: Stable bonded glass fibres will not slump within the wall cavity, settle or break down during normal applications.
