What is RB Silent-Tread Sound Reduction Underlayment?

RB Silent-Tread is an acoustical underlayment designed to dramatically reduce room-to-room and in-room ambient noise. RB Silent-Tread exceeds national building code and property association sound reduction requirements. RB Silent-Tread is the superior choice for High-Rises, Office Buildings, Hotels, Multi-Family Homes or just for the personal comfort of the homeowner.

Easy and fast to install, not only does RB Silent-Tread help reduce minor sub-floor imperfections, it lies flat. Versatile to use with most floor constructions, concrete or wood, and surfaces of laminate, hardwood, engineered wood and tile. RB Silent-Tread provides a 20-year Limited Lifetime Warranty - regardless of flooring brand or type of floor* when installed correctly.

In head-to-head sound testing, RB Silent-Tread outperformed the competition. RB Silent-Tread’s dense recycled rubber granules provide superior compression resistance so you can enjoy its benefits much longer than with most other underlayments.

Product Specifications

Why is Underlayment So Important?

“Your floor is only as good as the surface it is installed over.” Recent innovations in laminate, hardwood, engineered wood and tile continue to exhibit the “hollow” or “pingy” sound with foot traffic, voices, radio, TV, etc. When RB Silent-Tread is the underlayment of choice, RB Silent-Tread absorbs the sound waves inside the room and blocks other sound transmission to the room below.

RB Silent-Tread incorporates antimicrobial additive to inhibit the growth of mold, bacteria and algae. RB Silent-Tread XL (with vapor barrier) dissipates moisture, reducing potential harm to the flooring above and the subfloor below*.

RB Silent-Tread is fabricated from thousands of small rubber granules and offers superior underfoot comfort for standing, walking or exercising. The weight and durability of RB Silent-Tread allows RB Rubber to provide a limited warranty for the life of the floor. Other underlayments fail to provide the firmness necessary to resist compression from foot traffic and/or heavy furniture.

* Always follow flooring manufacturer’s written installation instructions. RB Silent-Tread XL (with vapor barrier) or other waterproof membrane should be used when installing over new concrete or concrete at or below grade level and wherever the flooring manufacturer recommends a vapor barrier. Waterproof membranes, if any, should be facing up toward the flooring surface. If moisture exceeds flooring manufacturer’s specifications, follow their installation procedures for moisture control.

Floating Floor

Check for subfloor moisture content. Always consult the flooring manufacturer’s written installation instructions, particularly with regard to moisture protection practices*. In most instances RB Silent-Tread XL (with vapor barrier) will meet the flooring manufacturer’s requirements.
Be certain the subfloor is clean, dry, smooth, level and structurally sound. Ensure that any nail heads are flush, smooth out any other sharp subfloor protrusions and fill any holes, gaps or indentions.
Starting in a corner, unroll RB Silent-Tread over the subfloor. RB Silent-Tread should be laid out perpendicular to the finished surface flooring to reduce seams.
Fit the perimeter edge at least ¼” from the wall by cutting to size. Roll out the next underlayment row in the same manner while butting each roll seam together tightly. Do not allow peaking or overlapping of seams.
Make certain there are no attachments or penetrations through RB Silent-Tread. If any, seal all tears or penetrations using duct tape or other utility grade, poly-coated cloth backed tape with an aggressive adhesive.
With RB Silent-Tread XL (with vapor barrier), tape all underlayment seams, tears, or penetrations using duct tape or other utility grade, poly-coated cloth backed tape with an aggressive adhesive.
Install the surface flooring according to the flooring manufacturer’s written installation instructions.

Glue-Down Floor

Consult the flooring manufacturer’s written installation instructions*. Be certain the subfloor is clean, dry, smooth, level and structurally sound. Ensure that any nail heads are flush, smooth out any other sharp subfloor protrusions and fill any holes, gaps or indentions.
Starting in a corner, unroll RB Silent-Tread over the subfloor. RB Silent-Tread should be laid out perpendicular to the finished surface flooring to reduce seams.
Fit the perimeter edge at least 1/8” from the wall by cutting to size. Roll out the next underlayment row in the same manner while butting each roll seam together tightly. Do not allow peaking or overlapping of seams.
Remove fitted sections making sure to note their location in the installation.
Starting in the farthest corner of the room, apply adhesive using a 1/8” x 1/16” x 1/8” V-notch trowel, making sure there is full coverage of the adhesive over the subfloor. Spread the adhesive at right angles to the seams in order to prevent oozing. Approved adhesive for gluing RB Silent-Tread must be polyurethane based, do not use petroleum based adhesives.
Follow immediately with RB Silent-Tread underlayment making sure the adhesive is still open, and apply even and full pressure to assure a full bond between the adhesive and RB Silent-Tread. Use a 50+ pound roller to ensure proper adhesive transfer rolling the width and then the length.
Make certain there are no attachments or penetrations through RB Silent-Tread. If any, seal all tears or penetrations using duct tape or other utility grade, poly-coated cloth backed tape with an aggressive adhesive.
Allow to dry per adhesive manufacturer’s instructions and install the surface flooring according to the flooring manufacturer’s written installation instructions.
