Acoustical Product Information

accoustical propertiesCellulose fibre, compared to other insulation products, has superior properties for improving noise suppression in wall, floor or ceiling construction.

There are four performance factors to consider; mass, damping, absorption and sealing.

 

Mass (Density)DampingAbsorptionSealing
Increased mass per unit thickness of cellulose fibre compared to other fibrous or foam insulation adds to the overall effectiveness of a wall, floor or ceiling assembly by reducing the transmission of lower octave sounds Unlike fibrous batts or foam boards, cellulose fibre incorporates itself as an integral part of a wall, roof or ceiling assembly. The natural ability for cellulose fibre to fill crevices and gaps produces a significant improvement in the sound damping characteristics of the assembly Cellulose fibre, because of the unique porosity of its interwoven fibres, will exhibit a NRC (Noise Reduction Coefficient) of 0.75 at a 25 mm (1 inch) thickness. Increased attenuation in both low and high frequency range is achieved due to absorption within an enclosed wall or ceiling cavity. Field reliability of cellulose fibre natural noise reduction capabilities is realized through its natural ability to fill crevices and voids normally occurring in wall, floor, ceiling or attic construction. Cellulose fibre will completely seal around complex shapes such as pipes, conduit and electrical boxes thereby ensuring its ability to minimize sound transmission through such interruptions
