Cellulose Insulation For Sound Reduction

Homeowners who choose cellulose insulation get the added value of effective sound control.
Cellulose insulation for sound reduction. Cellulose insulation works to reduce the lateral movement of sheetrock which decreases the amount of sound that can travel through walls. Cellulose s density produces less voids giving sound very limited space in which to travel. 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.
There are various soundproofing materials that do a great job at reducing noise. On a standardized basis foam and fiberglass provide an stc sound transmission class rating of 37 to 39. Installing cellulose insulation is one of the best methods available for sound abatement. Posted on 15 02 2020 12 04 2020 by liam.
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. Nrc values generally range between 0 and 1. The higher the number the better sound absorption. What is the best soundproofing insulation for noise reduction.
Nrc stands for noise reduction coefficient and is used to find out how much any product can absorb sound. Best soundproofing insulation for noise reduction. It s a question commonly asked but very rarely answered correctly. 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.
This type is typically. 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. Cellulose provides a higher rating of 44 resulting in less sound infiltration.
Cellulose insulation provides very effective sound control to minimize outside noises and between rooms if the interior walls are insulated. 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. In this article i will break down options. 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.
It is widely used to help limit exterior noise intrusions as well as for limiting noise between rooms. 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.
