High-density materials absorb sound better than lower density materials. With an installed density of greater than 3.0 lbs./cu. ft., cellulose insulation effectively absorbs sound by dampening vibration and blocking the pathways of air-born sound. Good sound absorbers are impervious and dense.
Rooms are noticeably quieter with Nu-Wool. Nu-Wool Cellulose Insulation deadens the transfer of sound from one room to another. Hotels, motels, apartments, hospitals, schools, churches, and multi-unit complexes use Nu-Wool WALLSEAL in their walls and Nu-Wool Insulation in their floors and attics for sound control. Even sound studios use Nu-Wool WALLSEAL for its superior acoustic properties.
Nu-Wool WALLSEAL is used to reduce the noise from outside a home, as well as noise from room to room, keeping music practice and other noises from interfering with activities in other rooms of the house.
