Cellulose Beats Fiberglass In Sound Proofing Demonstration

Dayton, OH (June 15, 2011)–The benefits of having a home properly insulated are readily obvious when it comes to saving energy and reducing home heating and cooling costs. Most everyone knows that having higher R-Value insulation and tighter seals makes a big difference in the efficiency of operating a home.

What you may not know is how much quieter your house can be depending on which type of insulation is used in the attic and walls. CIMA recently compared the sound proofing properties of cellulose and fiberglass insulation. The results were astounding.

“We knew cellulose insulation, with it’s density, had very strong sound proofing characteristics, “says CIMA Executive Director Dan Lea. “We set up and video taped this demonstration to show consumers just how much better cellulose is than fiberglass at cutting sound transmission–the results were quite impressive.”

The demonstration was independently produced on behalf of CIMA by Black Dog Productions in Joplin Missouri. The staff from CIMA producer member company Fiberlite Technologies assisted in setting up the demonstration.

Two heavy cardboard buckets and lids were used: one lined with three and a half inches of cellulose insulation and the other with three and a half inches of fiberglass insulation. While not exact, it replicates the typical drywall and insulation in a home. A 105 decibel(db) siren was placed in each bucket and a high quality decibel sound meter was used to compare the sound levels.

“Both cut the sound level but cellulose insulation reduced it at almost twice the level of fiberglass,“said Lea. “Cellulose insulation cut the 105db siren down to 40db versus fiberglass at 74db. A loud cocktail party is about 75db so you can clearly see how much quieter an environment encased by cellulose insulation can be.”
