Duracoustic soundproof underlayment offers a simple but very effective solution for creating soundproof flooring 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 a soundproof underlayment made from 85% recycled rubber. This sound deadening floor underlayment 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 underlayment has demonstrated outstanding sound attenuation with a variety of construction assemblies and floor coverings including ceramic tile, laminate, engineered, and soundproofing hardwood floors.
