Cellulose Insulation For Sound Reduction

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.

Cellulose insulation for sound reduction.

A real improvement for every home whether your home is in the planning stages or built 100 years ago cellulose will help keep it quiet a real improvement. Loose filled is blown into wall and ceiling floor cavities under a lighter pressure while the dense pack is blown in under higher pressure creating a solid 3 5 lb ft of density. The density of cellulose gives it an advantage over other forms of insulation such as fiberglass. Cellulose completely fills the spaces in walls and ceilings that help carry sound because it is sprayed in and provides a custom fit around wiring plumbing and other obstacles.

Cellulose is the other type of insulation. Cellulose provides a higher rating of 44 resulting in less sound infiltration. The higher the number the better sound absorption. Homeowners who choose cellulose insulation get the added value of effective sound control.

It is widely used to help limit exterior noise intrusions as well as for limiting noise between rooms. Best soundproofing insulation for noise reduction. Cellulose insulation provides very effective sound control to minimize outside noises and between rooms if the interior walls are insulated. Posted on 15 02 2020 12 04 2020 by liam.

Cellulose is the loose fluffy insulation that is blown into place. On a standardized basis foam and fiberglass provide an stc sound transmission class rating of 37 to 39. Nrc stands for noise reduction coefficient and is used to find out how much any product can absorb sound. What is the best soundproofing insulation for noise reduction.

In that regard this product is better than the ones i ve previously reviewed. Available in loose fill wet or dense pack cellulose not only provides a sound reduction but it is also an excellent thermal insulator. Sound insulation cellulose insulation can reduce sound traveling through walls and between floors. Cellulose s density produces less voids giving sound very limited space in which to travel.

Installing cellulose insulation is one of the best methods available for sound abatement. Many people only focus on the energy savings that can be achieved with cellulose insulation but overlook the benefits that come from improved sound insulation. As usual its efficacy dips toward the lower end of the sound range with an nrc of 0 39 0 51 in the 125 200 hz range. And in case you were wondering about the fire resistance of cellulose based insulation batts there seems to be no cause for concern.

Nrc values generally range between 0 and 1. Cellulose insulation works to reduce the lateral movement of sheetrock which decreases the amount of sound that can travel through walls. There are various soundproofing materials that do a great job at reducing noise.
