Floor Impact Noise Reduction Underlayment

  • Cost Effective
  • Reduces Impact & Airborne Floor Noise
  • For Use with Variety of Floor Finishes
  • Recycled Materials

Features & Benefits

  • Greatly reduces impact sound; rubber is the best sound absorption material
  • Increases IIC and STC ratings
  • Does not compress and therefore holds its acoustical value over time
  • Easy installation – will not slip or break down during installation
  • Conceals minor subfloor irregularities
  • Works extremely well over radiant heated floors
  • Resists mold, mildew and fungus growth

Environmentally Friendly

  • Made with 85% recycled tire rubber and is 100% recyclable
  • Low VOCs
  • Can contribute to LEED credits

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.
