Soundproof Underlayment for Sound Deadening

DURACOUSTIC S.T.O.P.™

Floor soundproofing is often overlooked when building a space, and can be some of the most distracting and reflective places on a project. Duracoustic S.T.O.P.™ floor impact noise reduction underlayment is designed to help with that problem. This underlayment is durable and resistant to ripping and bunching, making the installation easy. Additionally, the Duracoustic S.T.O.P.™ material resists mold and mildew, as well as compression, for longer performance and continued acoustical noise reduction year after year. This underlayment additionally is environmentally friendly and is a high-performance acoustic material. Find out more, and see product specs, below.

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 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.
