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.

 

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.

    Beneficial Insulation has completed evaluation and insulation of three residential homes for us. Two of these homes are in Wisconsin and one is in northern Illinois where my mother lives.

    We have a cape cod that was had a lot of air leakage and extremely uncomfortable in the upstairs bedrooms due to poor insulation in the attic. With air sealing and insulating the side walls our home is much more comfortable. The crew was very professional.

    Thank you very much for all your hard work. After hearing and thinking bad things about insulating contractors, it was a pleasure to do business with Beneficial Insulation Solutions. I have known for a long time that I needed more insulation in my attic.

    A little over a year ago, you installed quite a bit of additional insulation in our home. This note is just to say thank you for your excellent work and solid recommendations.

    In November we hired Beneficial Insulation Solutions, LLC to fully insulate our home. Owner Cliff Wakefield thoroughly explained the various options and procedures to us.

    Thank you Cliff for saving our gutters and a possible head trauma.
