Treadstone™ M3 Sound Attenuating Mat is a three dimensional mesh of Polypropylene Synthetic Monofilaments, UV stabilized, tangled and welded where they cross laminate to the Polypropylene Barrier Fabric. With its “cuspated” geometry, Treadstone™ M3 delivers the highest level of sound control between floor levels, with long term performance due to its excellent mechanical compression resistance.

Treadstone™ M3 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 7/8” (47.6 mm).

  • In conjunction with 1.5” of Treadstone™ Underlayment, the installed system can reduce impact noise (IIC) up to 16 dB in wood framed and 20 dB in concrete assemblies. Refer to Treadstone™ Acoustical Design Guide for acoustical test performance, or contact Formulated Materials for specific test data.
  • Polypropylene barrier fabric
  • Low profile; .3/8” or 8.5mm
  • Excellent noise control performance with a spectrum of floor covering options.
  • Flexible and resilient, while maintaining excellent 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 info@formulatedmaterials.com.

Treadstone™ M3 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

SURFACE PREPARATION

Clean, remove all foreign matter from surface. Surface must be dry.

APPLICATION

Treadstone™ M3 Sound Attenuating Mat is to be installed by a licensed Treadstone™ Dealer. The building must be closed in with a minimum of 50 degrees F, maintained for a period of 5-7 days during and after the installation of Treadstone™ M3 and Treadstone™ Underlayment. M3 is loose laid on the subfloor with seams tightly joined and fastened by peeling plastic film from butyl strip of overlap flap, and pressing firmly to the adjoining M3. The perimeter of rooms, adjoining walls, all fixed objects, and mechanical penetrations must be isolated with Treadstone™ Perimeter Isolation Strip.

STORAGE

Store in dry conditions.

  • Treadstone™ M3 is only one component of the floor ceiling assembly and overall noise reduction strategy. While using Treadstone™ M2 will improve the overall acoustics performance of the assembly, the exact amount or minimum performance cannot be guaranteed. Formulated Materials recommends contacting an acoustical consultant for recommendations regarding the acoustical performance of any and all projects.
  • To minimize risk of damage to the Treadstone™ Underlayment, installation of M3 and underlayment is recommended after drywall. For installation prior to drywall, contact Formulated Materials for recommendations.
  • Treadstone™ Underlayment thickness/compressive strength recommendations
    • Residential/Multifamily Construction: 1” (25.4mm) at 2,000 psi minimum
    • Light Commercial: 1” (25.4mm) at 3,000psi minimum
