Sound Attenuation: Treadstone™ R2


Treadstone™ R2 Sound Attenuating Mat is a cylindrical studded membrane made of a mix of UV stabilized recycled polyolephines, laminated to a polypropylene fabric. The rigid studded technology of R2 delivers superior durability and enhanced acoustic performance in the most challenging of projects.

Treadstone™R2 is loose-laid over the substrate and then covered with a uniform thickness of an approved Treadstone™ Underlayment Product. Mechanical Fastening is not required, providing a system profile thickness as thin as 1.15” (29.2 mm).
  • In conjunction with 1” of Treadstone™ Underlayment, the installed system can reduce impact noise (IIC) up to 12 dB in wood framed assemblies. Refer to Treadstone™ Acoustical Design Guide for acoustical test performance, or contact Formulated Materials for specific test data.
  • Polypropylene barrier fabric
  • Low profile; .15” or 3.8mm
  • Excellent noise control performance with a spectrum of floor covering options.
  • Industry leading compression resistance
  • Because this system is embedded, noise problems are reduced, even when floor coverings are changed or replaced
  • UL listed in over 110 designs, for specific design or data contact us at [email protected].
Treadstone™R2 Sound Attenuating Mat in conjunction with an approved Treadstone™ Underlayment, is recommended and approved in;
  • Multi-Family Construction
- Apartments
- Hotels
- Condominiums
  • Residential and Single Family
  • Commercial Office Space
