Cellulose Insulation Soundproofing

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.

Cellulose insulation soundproofing.

Cellulose insulation can reduce sound traveling through walls and between floors. Cellulose insulation is composed of 75 85 recycled paper fiber with the remainder being made up of fire retardant mater. The first is that cellulose completely fills cavities leaving few air pockets for sound to travel in. What this means is cellulose insulation can absorb 80 or more of the sound it comes into contact with.

Cellulose insulation works to reduce the lateral movement of sheetrock which decreases the amount of sound that can travel through walls. The significant difference between noise reduction with cellulose and fiberglass is its density. The density of cellulose gives it an advantage over other forms of insulation such as fiberglass. Sound deadening with blown cellulose insulation.

Cellulose is approximately three times denser then fiberglass. The thermal performance sound control and fire resistance that cellulose insulation like greenfiber provides help builders create quality.
