Additional details

Whisper Step is the most versatile acoustical underlayment available today. Not only does it help reduce in-room and between-story noise but also acts as a breathable moisture barrier. Whisper Step is guaranteed to perform over the life of the floor. It offers different installation methods making any project worry free. Always consult with the flooring and adhesive manufacturers for their product conditioning and installation recommendations and requirements. Vinyl Composition Tile is specifically excluded.

  • Excellent choice for Radiant-Heated flooring
  • Reduces impact and airborne noise in room and between floors. Reduces up to 10 decibels of in room noise and an overall improvement between floors of 25%
  • Prevents spills from getting into subfloor and allows moisture vapor to escape from beneath
  • Fresh Dimension antimicrobial works to inhibit the growth of mold, mildew, and odor-causing bacteria
  • Makes hard-surface flooring more enjoyable
  • The class leading extreme density not only resists compression but will perform for the life of the floor
  • Lays flat and helps mask minor subfloor irregularities; can be used above and below grade
  • Whisper Step is semi-permeable, which means vapor can pass up through it
