Why Acoustilead works best. First, Acoustilead is limp and dense which any good sound barrier must be. Secondly, it is thinner than any other acoustic material in the same sound transmission class.
There's a big difference in the ways in which sound or unwanted noise can be controlled. Porous materials absorb sound, but allow it to pass through at only slightly reduced intensity. Dense, limp Acoustilead, on the other hand, blocks the sound (prevents it's passage) and surpasses any other material as the ideal sound barrier. Acoustilead is easy to work with. You can fold it, form it, and crimp it around pipes, wires and ducts. By hand. You can cut it with a knife or shears. Staple or nail it to other surfaces. You can readily join it with adhesives and tape. Acoustilead is as easy to install as it is effective. What's more, installation costs are much lower with conventional, stiff materials.
