Great product!

By Grainman

from Wichita, Ks

About Me:

Pros: easy to use, Good value for the money

Cons: none

Best Uses:

Comments about Eco Silent Sound HD Underlayment: Used it under clicklock Morningstar bamboo. I did not experience any of the tearing and folded up problems some mentioned. It was installed above grade over OSB and in addition to taping the strips together with the attached tape, I stapled it about every 18" around the perimeter which allowed me to carefully walk on it with no problems of tearing. Easy to cut with scissors or sharp utility knife. Inner end of the rolls were hung over the staircase and almost all the wrinkles were out the next day.

Bottom Line: Yes, I would recommend this to a friend

Questions & Answers
Q: I am looking to glue down a click bamboo floor and would like to install an underlayment. I have talked to 5 different people at the local store and they have all given me different answers on what to do. Can someone tell me the correct way to use a sound barrior underlayment and how to install when we need to glue the bamboo floor down?

Answered on 2/23/2015 by cc-2

Q: The installation instructions for Ecosilent HD state that for floating floor over concrete the adhesive strip of the underlayment for the first row is to be laid next to the wall. Does that mean the adhesive strip is to lay flat on the floor next to the wall or that it lays vertically against the wall with the actual pad section of the underlayment running along the wall?
Asked on 2/20/2015 by Reno from St. Louis, MO

A: It sounds like you may be confusing the adhesive strip side with the moisture barrier film (flap) side, the flap will face the room (away from wall).

Q: We have 1/2" x 5" MorningStar strand carbonized bamboo and eco silent sound underlayment that we will be installing as a floating system on a concrete slab which is currently carpeted. We plan on covering the concrete with 6 mil poly sheeting, then the eco silent underlayment.
Question: We have read of several floating floor installations where the floor makes plastic crinkling noises when walked on. Are there any installation recommendations to minimize this sound?
Asked on 12/6/2014 by Tom from Beaufort, SC

A: Be certain that your underlayment and poly sheeting has no folds and your subfloor is flat and level. Subfloors must be flat and level with no more variation than 3/16" in 10' or 1/8" in a 6' radius.

Q: I'm installing a sold wood floor over a plywood subfloor and need at least a 50 sound rating to comply with local building codes? Will this product do that?
Asked on 10/20/2014 by San Fran Dan from San Francisco

A: most likely not especially if nailed down, It depends on the "floor ceiling assembly" (structure) and what sound insulation barriers are in it.
This underlayment will decrease sound transfer when installed under a floating floor by 22 db (IIC 22 db).

Q: Installing Eco Silent Sound HD underlayment under my Schön Quick Clic Engineered 7/16" x 4-3/4" Canadian Maple. The floor is going down on a concrete floor. Not a concrete subfloor. Some of the responses here recommend a vapor barrier before the Eco Silent for a concrete subfloor. Do I misunderstand the terms here? Concrete floor is a primary slab, >20 years.

Q: can I staple the underlayment down instead of using adhesive?
Asked on 9/1/2013 by ernie

A: This depends on what installation you are performing. For a floating floor you don't even need to staple except for maybe a couple to keep the Underlayment down while working. Same goes for a nail down installation. When performing a glue-down installation, the Eco Silent needs to be fully glued to subfloor and then flooring fully glued to Eco Silent.

Q: Can this product be used under porcelain tile on cememt floor for sound suppression?
Asked on 7/30/2013 by Hilary from Denver, Colorado

A: Unfortunately this underlayment is not designed for tile installation.

Our Insulayment can be used under tile flooring;
SKU: #10014403 100 SQFT ROLL $50.00/EA
Setting Materials:
• Use Latex Portland cement mortar that conforms to test requirements found in ANSI A118.4 or 118.11.
• Hydrate (mix with water) according to the bag recommendations.
• Use a slow mixer (300rpm or less) or mix by hand.
• Allow mixture to slake per manufacturers instructions and then lightly remix.
• Mix epoxy grout as per manufacturers instructions.
• Use epoxy grout as per ANSI A108.4.3.0 or ANSI A108.6.3.0 or ANSI A108.9.3.0
Trowel Size:
• Insulayment to sub-floor: 1/4”x1/4”x1/4” Square or “U” notch.
• Tile to Insulayment: Use a square or “U” notch trowel with notch size
appropriate for the size and type of tile installed and required to achieve 95% coverage.
(Minimum 1/4”x3/8”x1/4”)
Concrete Requirements:
• Maximum variation of 1/4” in 10’-0”. Deflection is not to exceed 1/360 of span.
• All cracks in excess of 1/16” must be repaired with appropriate materials.
• Surface must be clean, dry and free of contaminants and sealers.
• Lightweight concrete surfaces must comply with manufacturers specifications for ceramic tile installations including minimum compressive
strength and application of primer/sealer.
Installing Insulayment:
1. Roll the Insulayment out and trim to fit the floor using a sharp utility knife and a straight edge.
2. Be sure to run the Insulayment to the edges of the perimeter leaving no gaps.
3. Pull back the pre-cut pieces.
4. Dampen, but do not saturate, the concrete floor and the bottom side of the pre-cut Insulayment pad with a sponge or a mist sprayer.
5. Key the thin-set mortar into the sub-floor with the flat side of the trowel then comb it with the notched side using a left to right motion.
6. Apply the thin-set mortar only as far ahead as will allow installation of the Insulayment prior to the mortar beginning to set or “skin over”.
7. Unroll the Insulayment into the thin-set.
8. Immediately (within 10 minutes) roll the Insulayment with a 75lb roller in diagonal directions.
9. Do not walk on the rolled areas for at least 16hrs. Allowing traffic on the installed Insulayment prior to full set may cause indentations resulting
in weak areas and hollow spots.
10. Make sure there is at least 95% transfer of the thin-set.
11. Seams should be butted together, leaving no gaps or overlaps.
12. Allow the Insulayment to set for at least 16 hrs.can be used for this application:

9. Do not walk on the rolled areas for at least 16hrs. Allowing traffic on the installed Insulayment prior to full set may cause indentations resulting
in weak areas and hollow spots.
10. Make sure there is at least 95% transfer of the thin-set.
11. Seams should be butted together, leaving no gaps or overlaps.
12. Allow the Insulayment to set for at least 16 hrs.
Setting Tile:
1. Dampen, but do not saturate, the Insulayment with a sponge or mist sprayer prior to thin-set application.
2. Use a square or “U” notch trowel size that is appropriate for the size of tile. (Minimum 1/4” x 3/8” x 1/4”) and required to
achieve 95% coverage
3. Use Latex Portland cement mortar that conforms to test requirements found in ANSI A118.4 or 118.11.
4. Key the thin-set into the Insulayment with the flat side of the trowel and then comb it with the notched side using a left to right motion.
5. Press the tile into the thin-set using a front to back motion perpendicular to the spread of the thin-set for maximum transfer of the thinset onto
the tile.
6. Mortar average coverage per tile shall comply with ANSI A108.5.3.3.3, which requires, 1) the backbuttering of each tile, 2) at least 95%
thin-set coverage on each tile.
7. Minimum grout joint width is 3/16”.
8. Allow no traffic on the tiled surface for at least 16hrs.
9. Use epoxy grout as per manufacturers instructions

Among other things, the room will be used for dance practice by a small number of people (and the occasional party dancing), and we would like to have a floor that doesn't kill people's feet and knees. The laminate already has a cushion base (approx 3mm). Would adding a single layer of the Eco underlayment help with this? Would it create any problems with functionality or durability of the floor?
Asked on 12/10/2012 by Chuck from Indianapolis, IN

A: Eco Silent is approved for use with laminate flooring with padding attached because it is stiff enough to support the locking joints. It would not help as a cushion. You don't want any underlayment that would damage the joints.

on the subfloor. Follow the flooring/adhesive manufacturer’s instructions
for trowel size and spread rate for the flooring installation on
the underlayment. Trim off the excess overlapping film

Roll out underlayment with tape strip next to wall. Roll out next row in

Q: Dear Sir/Madam:
I am helping a friend decide on flooring for a smsll bathroom in a wood-frame house (on blocks - no slab), with a plywood sub-floor. The house was "family-built" ~ 100 yrs ago (Nothing, & I mean NOTHING, is square or level). I have advised cork flooring, & wonder if this is correct.
Also, in regards to the installation, would this eco underlayment be compatible? It sounds perfect, as far as the leveling of slight imperfections, sound & moisture barrier, etc. In addition, if this product is compatible, what would be the recommended method of installation for the underlayment (& the 11-5/8"x35-5/8" cork flooring on top of it)? Please keep in mind that the house will be shifting over time, & is already unlevel, off-square.
Please excuse any typos, as I am typing this on a smartphone, w/out my reading glasses.
Thank you for your rime and assistance.

Q: I am trying to lay my engineered hardwood floors. The floor is level and I laid the Ecosilent underlayment. Now, when I place the foor planks, some of the ends don't meet. The underlayment is buckling in spots and I can't seem to get it to lay flat. This is a large room about 25 by 18 ft. I have taped all the seams, but there is buckling. Another problem is the air vents. The air from the vents is travelling under the underlayment and it is billowing up. I tried using duct tape around the edges, but with humidity, the duct tape won't last long. How do I get this stuff to lay flat?

Q: I purchased handscraped engineered flooring for our living room. I found out that 1/3 of the floor is lenoleum, 1/3 hardwood covered with plywood, and 1/3 concrete covered with 3/8in plywood. Do I "float" the eco silent underlayment over all three surfaces and glue the engineered flooring onto the eco silent underlsayment?
Asked on 7/13/2012 by Pastor Steph from Culver City, CA

A: I would not recommend this application method.
Actually if the substrate(s) are level you can do a floating installation over the Eco SS by edge gluing the engineered flooring together.
You can find complete installation instructions on the product page by clicking on the specs tab and then clicking on - Installation Guide.pdf

Q: We have a mexican tile floor installed directly on plywood. If a nailed down wood floor is installed with eco silent, what IIC could we expect if we have a WOOD sub floor?

What IIC rating could we expect if we put a new subfloor (with eco silent on both sides of the new subflooring)?

Q: we bought a new condo about 2 months ago & the people above us are vert heavy footed & have a granddaughter that they let run around & makes loud thumping for several hours a day would u suggest this product for a ceiling & either put up cork flooring or bamboo to help with the heavy walking. Will this even work to remove some of their foot noise or would u suggest someithing else. We have custody of our 6yr old granddaughter who has truamatic brain injury & we need for the sound to be less so that it does not bother her to take her rest & nap periods... I appreciate any advice or help u can share with us. thank you so much sewfie
Asked on 7/8/2012 by sewfie from Cold Springs, Ky

A: Unfortunately there is nothing that we carry that I could recommend for your application.
Perhaps a suspended ceiling with acoustical panels would be the answer for your situation.

Q: Do you have a comparison sheet of the sound absorption between the ECO Silent Ultra vs 1/4" (6mm) cork underlayment? My condominium Home Owner's Association (HOA) requires the 1/4" cork, but from what I can find, the ECO is roughly 50% better with sound absorption. The cork spec sheet on here doesn't list the IIC or STC properties, while the ECO shows:

Also, we have 9" cement floors/ceilings. Does that mean these ratings would increase by 50% for the extra 3" of cement? Do you have figures for 9" floors?

IIC Flooring Sub-Floor
59 Hardwood 6" concrete with ceiling assembly

STC Flooring Sub-Floor
58 Hardwood 6" concrete with ceiling assembly
