Frequently Bought Together

Product Overview

Best Acoustical Underlayment irons out little subfloor imperfections while quieting impact sounds and floor-to-ceiling noise. Not only does it dampen ambient sound in the room it's installed in, but it also inhibits sound from traveling into the room below. Although it is promoted as an upgrade underlayment taking the place of poly foam, it doesn't carry a heavy upgrade price when compared with cork or rubber. In recent head-to-head Sound Transmission Loss tests, Best Acoustical Underlayment outperformed both cork and rubber in the majority of test band frequencies. Certified field sound tests were performed on an installation over a standard 6 in. concrete sub floor, and received an FIIC score of 71.

  • Environmentally friendly, utilizing over 89% recycled fibers; green product in contrast to petroleum-based underlayment
  • Synthetic fiber pads are fast becoming the most specified underlayment for floating wood and laminate floors by architects and designers because of their acoustical and moisture protection qualities
  • Superior acoustical test scores that generally meet or exceed the requirements for sound barriers between floors in multiple housing construction set forth by most municipality or condominium association building codes
  • Roll measures 400 in. x 36 in. x 1/8 in.
  • Designed to draw sound in and help deaden it, not deflect, helping make laminate floors sound more like real wood
  • It has an Impact Insulation Class (IIC) rating of 60 and a Sound Transmission Class (STC) rating of 54
  • Offers great moisture protection
  • Can be installed over wood or concrete subfloors

Can this be used on a wall?

This question is from Best 400 in. x 36 in. x 1/8 in. Acoustical Recycled Fiber Underlayment with Film for Laminate Wood

April 8, 2015
I live in a condo and my bedroom abuts my neighbor's unit. They are loud partiers and have a very yippy dog. I would like to do a bit of sound dampening on the wall behind my bed. I was thinking that I could use this product and then use rolls of cork on top for further sound insulation and to provide a smooth surface to paint.

Does anyone know if this would work? If not, is there a similar product for walls? I don't want to have to remove the drywall, since this will be a truly do-it-myself project.

My condo is a loft with 12' ceilings that are concrete and I was actually thinking of using the cork on the bedroom ceiling too, to dampen sound and provide more insulation.

Thanks

Answer: 
If you don't want to remove the drywall, I believed you could use this product to dampen sound and provide insulation; it has a film as heat barrier. I can barely hear my daughter steps now that I have this underlayment in my bedroom that is in top of the garage. Good luck.

Hello rpoppins,
The underlayment will help to muffle the sound a bit with the cork board pushing that further.
There are a couple of products that may work better for you in the case of this project. I've listed brief descriptions and links below.
First is the dB-3 acoustical barrier roll. The material is very similar to that used for soundproofing in motor vehicles.

Next are acoustic panels. These are 12 x 12 panels of sound dampening material. A benefit of the panels is that they can be hung as independent units to add a bit of design. The material composition is similar to that of the dB3.

I hope this is helpful.

I bought this product to install in my living room under some laminate flooring. Is this ok on top of a concrete floor? will moisture be an issue on the bottom felt side? Just seems like the felt could potentially hold in moisture itself.

Answer: 
You will have to use a moisture barrier. Concrete always sweat. I am using it on 3/4 inch osb sub-floors. This underlayment has a plastic film for heat barrier. In my opinion with concrete you will need something like 6 ml plastic before installing this underlayment. Sold in The Home Depot painting section. Good luck.

Answer: 
It has two sides, one side is felt, the other side is a plastic material. Per the manufacturer, it is a moisture barrier. I probably did a little bit of overkill since I installed a thermal barrier that doubled as a moisture barrier underneath this underlayment, but I figured it would be better to make sure the floor isn't cold before installing all the flooring!

If you need to 'build up' the wall to match the field tile, there are 2 ways you can approach doing it.
First, and this is the more time-consuming way, is to remove drywall (tile should never be installed over drywall unless it an item like SimpleMat is placed over it) and install tile backerboard, in more than 1 sheet to make the wall flush.
The 2nd option would be to do what tile installers call 'buttering' or adding copious amounts of tile mortar.
In your case, you'll need to make sure you use a mortar that is rated to be applied vertical surfaces. One we carry is a Granite and Marble thin-set mortar that can work on your accent tiles nicely.
This thin-set is sold at your local Home Depot in the tile aisle, and is one of the best tile adhesives we sell to successfully adhere tile to a wall.

We have a Dricore subfloor over concrete in a section of our garage (being used as a mudroom) and the Dricore instructions say we should use an underlayment if putting linoleum on it. Would this be okay to use as an underlayment between the subfloor and the linoleum?
Thank you!

Use ¾" flooring fasteners that do not penetrate the moisture barrier on the underside of the DRIcore® panels.
Do not glue the plywood underlayment to DRIcore® panels. Do not glue adhesive-backed vinyl tiles directly to DRIcore® panels.
Glue the vinyl floor to the plywood underlayment according to the vinyl manufacturer's installation instructions. Only remove the ¼" wall spacers after the vinyl floor has been installed."

Rated 4.5 out of 5 by 45 reviewers.
Rated 5.0 out of 5.0 by Worth the price. I am a 64 years old lady and I have never done anything like this before but I wanted to try. I bought a very inexpensive laminate floor with very good reviews hence I was able to go for a more expensive underlayment. I saw this one at the store and I decided to go with this one. No other would have worked for me. It does not have a seam tape attached but I bought a mesh one used for sheet rock. Perfect match. I am in the process of buying more of the 40 boxes of laminate that I bought and I will continue with this underlayment. Not need to experiment with others. Very easy to spread it and tape it and I did it without help. Buy a good sharp blade. My no expensive laminate sounds like a high end wood floor, it sounds solid to walk on it. Very happy with the results. October 20, 2015
Rated 5.0 out of 5.0 by worked well This was very easy to use in a loft area of a cabin. June 21, 2016
Rated 5.0 out of 5.0 by Excellent underlayment After researching several types of underlayment for my wood flooring project i chose the MP Global Best. The project is an engineered wood floor installed over a concrete slab (floating) and the results have been very good. What I like most is the floor has a more solid sound when walking on it, compared to the hollow, clicking sound some underlayments have. Easy to install, reasonably priced, and free delivery. June 7, 2016
Rated 5.0 out of 5.0 by Easy to work with and install We just completed installing engineered wood floors (HomeLegends) and used the recommended BEST UNDERLAYMENT, it was very easy to install and helped "even out" the little flaws in the cement slab we were installing on. It is comfortable to walk on and seems to block out noise. June 2, 2015
Rated 5.0 out of 5.0 by love it! Worked great! One side has tape so when you get one section done you don't have to worry about it sliding. Easy to use! April 7, 2016
Rated 2.0 out of 5.0 by I Recommend Eco Cork Instead I recommend Eco Cork instead of MP Best. We installed a 12 mm laminate over the Best product and were immediately disappointed with the echoic sound. Very cheap sounding. We pulled up the floor and replaced the underlayment with Eco Cork and the difference was dramatic. The hollow sound was replaced with a solid sound. maybe not like real wood but definitely a quality sound. That being said, the MP Best was much easier to install than the Eco Cork. January 18, 2016
Rated 5.0 out of 5.0 by Orange is the new Blue I was about to special order MP Global's Quiet Walk when I spotted this. Called them and it is the same thing, only with orange film. It is much like the recycled fiber wall insulation or carpet padding, in a dense 1/8" layer. No nasty smells, no toxic outgassing. It does have antimicrobial protection, called Aegis Microbe Shield, but that adds no detectable odor. Several competing products were so bad even their samples were intolerable. They say to put the vapor barrier film side up, and leave a large gap around all edges. The thinking is that if water is spilled near the edge of the floor, it will run down to the subfloor and under the vapor barrier - which will protect the finish flooring from the damp fiber. Since I'm doing a bedroom with no water sources, I put the vapor barrier down and extended it over the foam seal at the bottom of the wallboard. The room is now 100% vapor sealed from the ancient wood of the framing and subfloor. The finish flooring is extra hard strand woven bamboo. The fiber makes a huge reduction in the noise level compared to hard flooring directly on the subfloor - worth the cost! February 10, 2016
Rated 4.0 out of 5.0 by Great Product Installing this product before laying down my new floor made a big difference in my apartment - where the store downstairs plays loud music - cutting down the sound transmission and restoring my sense of privacy. Major improvement. January 13, 2016
