    Hi Lisa, You can view the IIC sound ratings here:

    Please refer to your flooring manufacturer adhesive recommendations.

    This product will not prevent moisture from concrete. Yes, you can put this product on top 6-mil vapor barrier as 6-mil vapor will block all moisture.

    No, SoundBuffer cannot be used for ceramic tile. AbsorbaSound is a great product that will work excellent for ceramic tile.

    It is approved to be used with radiant heat systems.

    Unfortunately that is not a recommended application.

    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.

    Noise Cancelling
    SoundBuffer's unique structure controls impact and airborne noise to cushion the floor, absorb sound & help make laminate sound like real wood.
    • IIC 68
    • STC 64
    • Delta IIC 22
    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.
