Sound Control

Cellulose Insulation is widely used for its excellent sound reduction qualities, giving industry professionals the opportunity to further enhance their projects. The high density fibers naturally absorb noise and reduce sound transmission. When used in exterior walls Fiberlite’s Cellulose Insulation, reduces outside noise entering a home or building. In addition, these products are ideal for interior areas such as bedrooms, bathrooms and between floors in 2-story and basement homes as well as between living areas in multi-unit structures. Here we explain how Fiberlite’s Cellulose Insulation controls sound:

Noise Reduction Coefficient (NRC)

The Noise Reduction Coefficient measures the build-up of noise within a space. A single number index rating is used to measure the sound absorption quality of a material. Fiberlite’s Cellulose Insulation products have an NRC rating that ranges from .75 to .82 depending on the wall, floor or ceiling design. Simply put, Fiberlite’s Cellulose Insulation will absorb 75% to 82% of the sound it comes into contact with.

Sound Transmission Class (STC)

The Sound Transmission Class measures the sound transmission between spaces. A single number rating is used to measure an assembly’s ability to impede sound transfer. The higher the STC rating, the more effectively a wall, floor or ceiling controls sound transmission. Loud speech can be understood through a wall with an STC rating of 30, but should not be audible through a wall with a rating of 60. Fiberlite’s Cellulose Insulation may be used to achieve STC ratings from 44 to 68 depending on the partition assembly.
