Silent Tread Underlayment

The sound deadening characteristics of recycled rubber are unrivaled and widely recognized, and Ultimate RB is proud to offer a complete spectrum of recycled rubber acoustical underlayment. Available in thicknesses from 2mm to 12mm for both residential and commercial applications, Ultimate RB has a sound solution for your requirements.


No other playground surfacing material offers the degree of safety assurance that rubber tiles can provide. Ultimate RB Bounce Back Playground Tiles are shock absorbing, resilient, rubber tiles that provide long-term answers to playground safety and features ADA accessibility.

Highly Compatible & Ease of Installation:

Silent Tread Commercial Underlayments are compatible with a variety of flooring materials including hardwood, engineered wood and tile. They are also compatible with a wide variety of sub-floor configurations. For use with laminate, hardwood, ceramic tile, and engineered wood floor systems, Ultimate RB’s SILENT-TREAD is designed to reduce room-to-room and in-room ambient noise. Superior density allows the product to lay flat during the installation process.

Superior Sound Reduction & Crush Proof:

Silent Tread, which is comprised of up to 86% post-consumer recycled content, contributes to sound reduction within a room, and helps block sound transmission to the room below. Ultimate RB Silent-Tread outperformed the competition in head-to-head field testing for noise reduction. It has three times the sound dampening weight of competing products. Silent-Tread’s durable rubber material will not be crushed or degraded by the flooring system. It will retain its noise reduction capabilities for the life of the floor.

Environmentally Responsible & Mold/Mildew Prevention:

Being made from recycled tires, Silent-Tread Commercial Underlayments qualify for Executive Order 13101, and their use can contribute toward LEED Green Building Council Certification. Silent-Tread incorporates an anti-microbial ingredient to help prevent the growth of harmful mold, mildew and bacteria in accordance with nationally recognized standards.


Custom Sizing & Superior Comfort:

Ultimate RB’s unique manufacturing processes allow for custom sizing options that no competitor can offer. Recycled rubber offers cushioned comfort that is unmatched by any other surfacing material. All Ultimate RB products are proudly made in the United States of America.


All products are made from 100% recycled rubber and a specially engineered polymer binder. Because of the high level of recycled material in our formulation, these products meet and exceed the requirements set forth in the U.S. Executive Order 13101, Greening the Government and can be a contributing factor towards LEED Green Building Council certification.

Manufactured for Durability:

Custom-formulated, high strength polyurethane binders, similar to those used in synthetic running tracks, are used in the construction of Ultimate RB products. When they are combined with recycled tire crumb in our unique manufacturing processes, an extremely durable material is produced.

Minimal Odor:

Ultimate RB’s unique manufacturing processes virtually eliminate the strong sulfur odor (rotten egg smell) prevalent in virtually all competing products. Our products are made from recycled rubber, but they don’t smell like they are.
