Duracoustic sound control underlayment offers a simple but very effective solution for creating floor systems which meet stringent sound ratings in multiple-story dwellings, condominiums, hotels, apartments, private homes and business applications including old building conversions into condominiums.
Duracoustic is made from 85% recycled rubber. It is a reinforced rubber mat with an open cell structure which enhances its sound deadening properties making possible the installation of cost effective sound rated floors.
The Duracoustic underlayment system acts as a decoupler by breaking the sound transmission path through the floor-ceiling assembly and prevents noise flanking room to room. Testing has demonstrated outstanding sound attenuation with a variety of construction assemblies and floor coverings including ceramic tile, hardwood, laminate and engineered wood floors.
