Duracoustic soundproof underlayment offers a simple but very effective solution for creating soundproof flooring systems that meet stringent sound ratings in multiple-story dwellings, condominiums, hotels, apartments, private homes, and business applications including old building conversions into condominiums.

Duracoustic is a soundproof underlayment made from 85% recycled rubber. This sound deadening acoustic underlay is a reinforced rubber mat with an open cell structure which enhances its sound deadening properties making possible the installation of cost-effective soundproof flooring.

The Duracoustic sound deadening floor 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 on this soundproof floor underlayment has demonstrated outstanding sound attenuation with a variety of construction assemblies and floor coverings including ceramic tile, laminate flooring, engineered, and soundproofing hardwood floors.
