The compressed material needs time to rebound to its original thickness. The cotton insulation comes in compressed rolls or batts. How to Install Denim Insulationĭenim insulation soundproofing installs the same way stone wool and fiberglass insulation do, through compression fit. Denim insulation has an NRC average of 1.15 and an STC value of 52, making it ideal for soundproofing applications. Those that are deflected get trapped in voids or pores, which convert the frequency energy into heat. Soundwave frequencies penetrate the insulation and bounce off the different facets of the fiber, or are caught in the pores. The fiber and insulation structure work together to improve soundproofing. The manufacturing process also ensures there are voids within the compressed panels. The fibers are multi-dimensional, porous, and dense. Insulation made from blue jeans and other cotton products is good for soundproofing. Is Denim Insulation Good for Soundproofing? The cotton material is easy to work with, has no VOC off-gassing, or irritating carcinogenic filaments. It can also be used in acoustic traps, panels, and to wrap plumbing, duct, and HVAC pipes. There is more surface area within the material to interrupt and transform sound energy into heat.ĭenim sound insulation cuts sound transmission through walls, floors, and ceilings. The porosity and density of the insulation, coupled with the fiber shape, contribute to denim’s superior STC rating of 52, and NRC value of 1.15. The porous, multi-dimensional natural fibers of blue jeans insulation make for excellent sound absorbency.
