Great product!

By Grainman

from Wichita, Ks

About Me:

Pros: easy to use, Good value for the money

Cons: none

Best Uses: Laminate Underlayment

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

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: 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:
Setting Materials:
• Use Latex Portland cement mortar that conforms to test requirements found in ANSI A118.4 or 118.11.

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.
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.

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.

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?

Q: What size of gaps/ imperfections can this cover?
Asked on 4/8/2012 by Spencer from Lake Mills, IA

A: Nothing major. Subfloors need to be flat and level for any floor. Floating laminate or Quick Click Engineered subfloor needs to be very flat and level with no more than 1/4" in 8' variance.

Subfloor for solid hardwood needs to be within 3/16" in 10’ or 1/8" in 6' variance. Options are Sand high areas or joints, use wood shims wedged between joists and the subfloor to raise it. Protruding nails/staples should be ground flat. Build-up low spots with layers of 15 lb builders felt, old vinyl, plywood or shims (do not use cement leveling compounds).

When subfloor is off too much, add a layer of 5/8" CDX Plywood and correct leveling issues with shims, ripped down framing lumber.

Q: My dining room and living room are adjacent to each other. The dining room is on concrete slab - the living room is subfloor over the basement. What type of flooring could I use to run continuously in both rooms and what underlaying should I use. Thank you.
Asked on 1/31/2012 by Marg from Willoughby Hills, Ohio

A: If your concrete is flat and level and perfectly even with your old hardwood flooring; you could lay a floating plywood subfloor as described in this article -

After laying 8mil plastic sheeting as a moisture barrier over the cement, overlap seams 4” and duct taped. Lay one layer of 1/2” plywood over the plastic sheeting, lay another layer of 1/2” plywood on a diagonal over the first for stability, screw both together using a 6” screw pattern do not puncture plastic. Keep an expansion space of 1/2" from all walls. If plywood sheets are not Tongue and grooved provide a 1/8” gap between all sides of adjoining plywood panels. Install new flooring over 15 Lb roofing felt. From NOFMA

If everything is very flat you may be able to use Elastilon instead of losing height with a ply system. Elastilon is a good option for concrete or wood subfloors. You can use up to 3/4" thick or thinner solid or tongue and groove engineered flooring. Floating with Elastilon needs to have an expansion break for spans over 33' on it's width, not length.

Q: Is Eco Silent the right underlayment to go on top of radiant heat? The specs show a R value of 2.3 which is huge considering how thin the material is and considering that 1 inch of wood has an R value of 1.0. I'm concerned that it will not allow good heat transfer from the hot water tubes (in gypcrete) through the 3/8" solid bamboo floor I purchase from LL.
Asked on 12/13/2011 by I wanna know from Steamboat Springs, CO

A: Eco Silent Sound is approved radiant heat floor systems.
You will need to check with the manufacturers recommendations of the maximum R-value that you can put over the system you have.
Most Radiant floor heat system manufacturers require a non-closed cell floor covering with a total R-value less than 2.50.

Q: I'm installing unfinished 3/4" Brazilian Cherry hardwood using nail-in staples in a single story house. There's a 3 feet high crawl space below the subfloor. And the subfloor is about 1" thick. Since I'm stapling the 3/4" floor into the subfloor, it will puncture the Eco Silent Sound HD. Should I add a layer of 15 lb felt paper to serve as mositure barrier? If so, would the felt paper be under the Eco Silent Sound HD Underlayment?
Asked on 12/7/2011 by Jon from San Francisco, CA

A: I would recommend our Silicone Vapor Shield (SKU #10021412) for this application.
VENTILATED CRAWL SPACES To prevent moisture build-up homes with crawl spaces must have vents for proper cross-ventilation.
Provide year-round air circulation with multiple vents. Venting allows damp areas to dry-out. Vents must be adequately spaced so that no dead air spaces remain. Under the home in the crawlspace use black 6-mil polyethylene sheet plastic as a moisture barrier. Completely Cover 100% of the surface of the ground to guard against excessive moisture. Overlap plastic seams 6” and duct tape.
Delay installation until the above guidelines are completed.
MOISTURE TESTING
[CAUTION] Most installation failures result from moisture. All subfloors must be tested for moisture content. Know your moisture levels and document the readings. Do not deliver flooring to the jobsite until moisture problems are corrected.
Wood subfloors: Using a moisture meter, determine if conditions are dry before installing. Wood subfloor moisture reading must not exceed 12%; the ideal moisture content within new wood flooring is 6%-9%. The differential balance between new boards and subfloor must not exceed 4% or 2% for board widths over 2 1/4”. If moisture readings are too high, postpone the installation, find the moisture source and correct. Raise heat and increase ventilation, holding off installation until proper conditions are met.

Q: How do i install eco-silent underlayment? I have installed it before with nothing underneath it i have also tried staples to keep it down but it bunches up no matter what i do. I really like to use this product cause its great when the project is done. But how do i prevent it from bunching?
Asked on 12/2/2011 by anonymous

A: QUICK AND EASY INSTALLATION
requires no additional seaming tape, cuts with a knife
1. Install Eco Silent Sound HD™ with film down against concrete/subfloor
2. If double glue down installation for wood flooring, use a urethane
based adhesive with a 1/16" trowel on the subfloor. With LVT and
vinyl plank flooring, use an acrylic or pressure-sensitive adhesive
(based on flooring manufacturer’s requirement) with a 1/16" trowel
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
3. Roll out underlayment with tape strip next to wall. Roll out next row in
same manner butting underlayment close to first row (do not overlap)
and covering the moisture barrier film. Remove the tape strip and
secure the overlapping moisture barrier film
4. Install flooring according to the wood manufacturer’s installation
instructions

Gluing the underlayment down is a good way to prevent it from bunching up during your flooring installation. Gluing is an extra expense so in most cases the product is tacked down to a wood subfloor using staples or duck tape can be used to hold it in place over concrete. Friction from sliding planks may cause it to bunch up so to help prevent this picking up the plank and setting it in place can help. Try to minimize the distance you have to slide a plank to install it.

Asked on 11/28/2011 by Cher from Berwyn

A: Always test the moisture content of the slab before installing. Eco Silent Sound can be used for double stick installations but is rated for slabs that have 4 lbs of vapor emmisions or less. You may need to consider using our Insulayment with a moisture barrier and adhesive depending on the test results.
You may be fine without a transition but? (at your own risk) consider the added thickness of the extra layer of adhesive/ moisture barrier and the movement factor.

Q: Is this all i need over 3/4 plywood sub floor. using morning-star quick click bamboo. I called the 1800 number today and the tech told me i cant use this product over a wood subfloor because this product contains a vapor barrier.
Asked on 11/22/2011 by Jack of all from New Jersey

A: I apologize for the misinformation given.
New revolutionary moisture vapor film for the best bond strength, durability and moisture protection. This film is made of a breathable polyester material and NOT polyethylene plastic ( like your 6mm film ). This unique film can be used on wood joist subfloors as well as concrete subfloors. On wood joist subfloors, the film prevents moisture vapor from reaching the installed wood flooring where damage could occur, without trapping moisture on the wood subfloor. Think in terms of a winter ski jacket – moisture does not penetrate the film material, yet the polyester material is still breathable, it does not trap moisture on the wood subfloor.

Q: can you staple down the ecosilent underlayment?
Asked on 8/27/2011 by anonymous

A: It does not need to be stapled down but sometimes installers tack the ends down to prevent them from rolling back up or you can use some boards to do the same.

Q: I am installing an engineered wood floor over concrete.
Is this underlayment glued down to the concrete floor, then the wood flooring glued to the underlayment? Or what is the recommended installation?
Asked on 8/15/2011 by anonymous from Pensacola, FL

A: Always test the moisture content of the slab before installing. Eco Silent Sound can be used for double stick installations but is rated for slabs that have 4 lbs of vapor emmisions or less.
You may need to consider using our Insulayment with a moisture barrier and adhesive depending on the test results.

Q: Purchaesd 8mm laminate flooring with pad attached. Laminate is going on new construction concrete floor, but am looking for best choice underlayment for cushion & noise reduction. What do you recommend, giving the lowest cost options first?
Asked on 8/6/2011 by anonymous

A: Either Eco Silent or cork underlayment is approved for padding attached laminate flooring only.

Answered on 8/10/2011 by Tech & Install

A: Keep in mind that the pad attached to the laminate will provide sound proofing. Using additional padding is not required but if you choose to use additional padding. I suggest using Eco Silent Sound or Cork underlayment as these are dense enough to support a laminate floor that already has a pad attached. It is also very important to place 6 mil poly sheeting as a moisture barrier over the concrete first before installing the laminate floor.

Q: I am considering floating an engineered floor in my living room. One flooring expert told me that one of the drawbacks of a floating floor is that there is a "hollow" sound while walking on it. I'm not exactly sure what that means, but will this particular underlayment help reduce any such hollow feel to the floated floor? Thanks.
Asked on 7/30/2011 by Dukeblue from NY, NY

A: Yes it is designed to absorb that hollow sound which some folks complain about. Will it feel like a naildown, almost but not exactly. Will that matter? To some yes and others will have no idea.

Q: Can this underlayment be used with face-nailed flooring? I am concerned about the face-nailed nails eventually backing out due to foot-traffic compression of the material.
Asked on 7/3/2011 by pheeliques from cincinnati, oh

A: The minimal amount of flex with this underlayment product should not cause the proper flooring fastener to "back out" of an appropriate subfloor.

Q: I am looking at flooring suitable for a concrete basement floor that will handle my daughter's dance practice (including tap). After visting your showroom, we are considering 12mm laminate such as "12mo". To reduce noise and increase floor temperature, the saleperson showed us the eco-silent HD - yet the website seems to indicate only cork could be used with the laminates. Please clarify and feel free to recommend basement flooring for tap dance and options to keep it from being cold. Thanks
Asked on 6/27/2011 by Tim from Elizabethtown, PA

A: Cork is currently the only approved additional underlayment that is recommended for a laminate that has pre-attached padding.
Low gloss laminates with AC3 ratings tend to be the most durable and scratch resistant. Many people also like to use ¾” hard solid wood flooring because it can be refinished many times if the dancing were to create a lot of scratches and wear to the flooring. Natural Strand bamboo could also work because it is such a hard species of flooring.

Q: When laying down and removing the adhesive strip; Can you reposition if you make an error in alignment? Is this underlayment "free floating" on top of the subfloor? Thank you.
Asked on 6/16/2011 by WRZ

A: You should be able to reposition the strip if needed to correct your alignment. This underlayment is free floating when installing a floating floor or nail down floor over it. If you are doing a glue down installation you will have to glue down the pad first and then glue down the flooring to the pad the next day.

Asked on 6/6/2011 by billybob from pensacola. fl
