Product Details

Pad glued-down and nailed-down hardwood or engineered wood floors with Insulayment to dampen sounds and conserve warmth. Simply glue the pad to a structurally solid concrete or wood subfloor and then adhere the planks directly to it. For ceramic tile, use latex-modified thinset mortar both below and above the Insulayment. The subfloor and installation materials must be in accordance with industry standards as outlined by the National Wood Flooring Association for wood floor applications, the Tile Council of America for ceramic and porcelain tile and natural stone applications.
  • Ideal for glue-down or nail-down wood flooring as well as ceramic tile
  • Can be used in conjunction with heated underlayment to fill in small non-heated areas for installations beneath glue-down wood flooring or ceramic tile
  • Impact Insulation Class (FIIC) rating of 60, Sound Transmission Class (STC) rating of 53, perfect for condominiums and apartment buildings
  • No attached vapor barrier, allows excellent adhesion with wood-flooring adhesives and thinset mortars
  • Suitable for commercial or residential use

Q:I have OSB subfloor and going to put down floor heating mat and then tile. Can I use this product between the heating mat and the osb?
by|Feb 1, 2023
1 Answer
Answer This Question

A:  Thank you for reaching out. The correct layer organization would be to put the QuietWarmth down on the substrate, install the insulayment over the QuietWarmth, then install the tile.

    A:  Thank you for reaching out. We have heard about customers using it in this manner and have had good luck. However, that is not an approved application and we have no testing data to back anything up.

          A dream to fit
          We've laid wood floor from 2 manufacturers in 4 rooms using 3 different underlays and this was the best of all for ease of fitting. The room we used it in had the most obviously imperfect floor. With some subfloor boards being obviously out of line. This covered the imperfections brilliantly and the floor went down so quick. We used nail down 2-1/4 and managed ~150sqft in about 17 hours. I just wish we'd used this from the start. Will be buying again as we replace the remaining floors.

            This doesn't seem to have much thermal insulation value. The goal was for both acoustic and thermal insulation. This seems more lik thin carpet pad than insulation. But it will help in decoupling for expansion differential concerns.

            10 Stars!
            [This review was collected as part of a promotion.] We ordered this about a month ago as we were doing some renovations. This came in so handy and came highly recommended by some friends of ours. This definitely helps with the sound control and insulates.

              This is a very nice product, and was easy to install and work with. My hardwood flooring manufacturer (3/4 inch oak hardwood nail down) specified a felt type underlayment that "does not" have a vapor barrier and this product fits that category. It gives some sound proofing qualities and a little cushion to the floor, it's very nice to walk on the finished floor. We have had it down for just a few weeks now and we are real pleased with the results. I ordered 6 rolls of this product from the home depot website (its not a regular stocked item in the stores) on a Monday and it was at the store and ready for pickup on wed. morning! Very Fast Free Shipping.....

              This product is supposed to be compression resistant, but please consider what you are installing. Although it says not to use with hardwood under 3 inches, I am using 3.6 inch boards and finding that it is difficult to install subsequent boards. This is due to the fact that when I nail into the tongue of the first board, it is compressing into the underlayment. Also, this product is quite dirty and easy to rip as you are moving around on it. The soundproofing seems to be pretty good. I hope I don’t have any problems after the install.

              Wanted to try something other than rosin paper and settled on this. Used with 3/4 in hickory hardwood & 2 inch staples. This underlayment worked well, easy to work with.
