Cellulose Insulation Provides Better Sound Control

Homeowners who choose cellulose insulation get the added value of superior sound control. It is widely used to help limit exterior noise intrusions as well as for limiting noise between rooms. Understanding how cellulose insulation can help control sound provides insight into this important performance feature that can help to limit noise from outside or between rooms inside the home.

Watch this demonstration video on the sound control capabilities of cellulose insulation to see just how effectively Cellulose Insulation performs. Then read below for more technical information on sound control and cellulose insulation.

Noise Reduction Coefficient (NRC)

Noise Reduction Coefficient measures the build-up of noise within a space. A NRC number index rating is used to measure the sound absorption quality of a material. Cellulose Insulation products have an NRC rating that can range upwards of .80 or higher depending on the product, and the wall, floor or ceiling design where the material is installed. What this means is Cellulose Insulation can absorb 80% or more of the sound it comes into contact with.

Sound Transmission Class (STC)

Sound Transmission Class measures the sound transmission between spaces. A single number rating is used to measure a structure’s ability to impede sound transfer. The higher the STC rating, the more effectively a wall, floor or ceiling controls sound transmission. Noises can be heard through a wall with an STC rating of 30, but should much less audible through a wall with a rating of 60. Cellulose Insulation may be used to achieve STC ratings as high as 70 depending on the wall or partition assembly where the product is installed.

The added value of sound control provided by cellulose insulation is just one more way consumers can benefit from the enhanced performance and value only cellulose insulation can provide. Request it from your builder or contractor and discover the benefits of a quieter living environment.
