    Compression Resistant

    Dense material will minimize the amount of denting and telescoping conformity the planks or tile can have to the subfloor.

    When installing SoundBuffer underneath a floating floor, please use a high quality duct tape at the seams. If you are using the double-glue or nail-down installation method, that is not required.

    SoundBuffer will help reduce minor subfloor imperfections, however it is not a substitute for proper subfloor preparation. Please ensure your subfloor is within tolerances of your flooring manufacturer prior to installing SoundBuffer.

    If you are looking for a test report please send an email to [email protected] and specify the product and type of report you are needing. We would be more than happy to email you a copy of any testing data that we have.

    It is not recommended to use any underlayment beneath peel and stick tile.

    SoundBuffer has an IIC rating of 68. To view specific test reports on all of our products, please visit our Knowledge Center and click on Underlayment Sound Test Tool.

    SoundBuffer is suitable for use with most flooring adhesives. We defer to your flooring manufacturer’s guidance on selecting a specific product.

    SoundBuffer does not prevent or protect from moisture in your concrete slab. We recommend selecting an underlayment from our QuietWalk family of underlayments. The QuietWalk products have a recycled fiber construction that wicks harmful moisture from the slab and allows it to safely evaporate, while protecting your new flooring with the bonded vapor barrier.

    No, SoundBuffer is not approved for use with ceramic tile. We recommend Insulayment for a ceramic tile application.

    SoundBuffer is approved for use with radiant heat systems. We recommend pairing with our QuietWarmth Radiant Heat Systems.

    SoundBuffer is not approved for use under sheet vinyl. Sheet vinyl is very thin and pliable; you could see issues with damage, wear, telegraphing, etc. SoundBuffer is approved for luxury vinyl tile or plank, laminate, and hardwood.

    SoundBuffer is not recommended for use on walls.

    Super workable and easily installable. Superb quality. I’m definitely loving the feel of walking across my new floor with this underlayment compared to when I was a flooring installer using the cheap stuff.

    I cannot speak for the sound deadening qualities as my installation was needed to isolate my floating LVP floor from residual adhesive from the previous vinyl tile floor, so I did not rate it the full 5 stars. The product was easy to work with and to tape the seams together. It laid out flat and the new flooring easily laid over it.

    amazing MP Global phone conversation and support

    I’m waiting for my Sound Buffer underlayment to be delivered. Had some questions about the installation. I’m able to call MP Global directly in one call, 3 rings, a live person on. She connects me with their product expert, no message, a live person again. My questions were answered clearly. I’m just amazed they are able to support customers in this personal way. I can’t wait to install my floor with their product.

    Smooths Imperfections
    SoundBuffer's dense rubber construction is firm enough to support the overlaying floor, but flexible enough to form around sub-floor surface roughness that may otherwise cause laminate panels to "rock" or lay unevely.
