First Thing’s First: Subfloors Made from Concrete If you were to rip up your floorboards, you’d see a subfloor made of either concrete
Worth the extra cost to use Eco Cork Foam! This underlayment is easy to work with and feels AMAZING. I used this under some engineered bamboo click-lock flooring and it softens your footsteps beautifully while not feeling squishy or making any kind of noise. My living room also has several very large (600-800 lb) arcade machines, and the weight distribution properties of this product help a lot with keeping the floor planks perfectly level.
This is a great product. Easy to put down. Exactly what I was looking for to be able to provide sound absorption in a room with high ceilings. A much more solid sound. A side note, it also made it easier on my knees during the installation.
Fantastic stuff, worth the money. Soft and comfortable underfoot, easy to install.
Made It Easier to Lay Flooring
So far made it easier to lay the floor, knees aren't damaged! Waiting for winter to see what it does to insulate the concrete subfloor. Yay!
Reduced Sound + Comfortable
Cork form was easy to install and feels great when walking on the flooring. Reduced the sound and is very comfortable.
Peace of Mind
Installed in a finished basement with 14mm laminate (2mm pad attached). Added underlayment gives real peace of mind for a basement install. Also has a much more comfortable feel than same flooring installed on 1st floor of home (plywood base). Easy install - chose to run underlayment perpendicular to finished flooring. No issues with the install.
Great for Rigid Core LVT on Concrete Slab
An absolute necessity when installing LVT on concrete slab. Added a good amount of height to my bathroom floor, and the insulation factor will pay off big time in the winter! Only downfall is the $$ and it’s somewhat of a pain to keep flat during install, since it’s rolled up. But it’s a no brainer and total investment when compared to the competition. Buy this!!
Easy to work with
Easy to work with. Used over concrete foundation, under vinyl plank adhesive flooring. Provides a nice cushion.
Easy to Install
Easy to install. High quality, firm padding. Floor does not squeak when walking on it.
Perfect underlayment for flooring. Easy to work with.
Great quality, worth its price.
Excellent result. Easy to use, and accomplished the result I’d hoped for. Glad that I spent the small additional price for a superior product.
Worked great to dampen sound
I am so happy that the sales associate recommended ECF underlayment for my vinyl plank floor. I used this over a concrete slab and placed my vinyl plank flooring over it. It was so easy to install and the built in vapor barrier saved me a step in the installation. The adhesive flaps were easy to use and now I can rest easy that my floor is 100% waterproof from the top and the bottom. I recommend this product to anyone who wants the piece of mind that ECF gave me.

Very Affordable + It’s Waterproof
Love this stuff, easy to lay down, very affordable plus it’s waterproof.
“Very Happy with Company, Product and Support”
Shortage during shipping, went to local store and customer service contacted company for me. Quickly sent replacement roll to fill shortage. Very happy with company, product and support.
“Worth the Money”
True to it’s description, after laying the laminate it felt very soft to walk on. Worth the money.
“Working Well Under My Vinyl Planking”
This underlayment is working well under my vinyl planking. Waited a month for the shipping but it's a quality product.
“It Worked Good”
Used for sound reduction on 2nd floor, it worked good.
“Worked Great, Easy to Use with Built In Tape”
Worked great, easy to use with built in tape. Love the soundproof quality.
“May As Well Use the Best”
Top quality product, no doubt a lifetime and then some durability. A little more money than other underlayment but well worth the extra. My installation was engineered wood, glued T&G. Easy to work with, cuts nicely with scissors or knife but extremely tough at the same time. Very happy with the end result. Floor is quiet under any footwear. I will definitely use this on future projects.
Worked perfectly on top of my plywood subfloor under my hardwood engineered planking. It does make it seem a bit softer and cushionier.
“The Product was Easy to Cut and Piece Together”
The product was easy to cut and piece together with the adhesive attached to the underlayment. It also improved the feel of the laminate when standing on it as well as reducing the echo sound in my room.
“Very Easy to Use”
Very easy to use. I have used it in two rooms so far and have not have any issues. It appears durable. Thank you Home Depot
Would recommend good quality.
“Really Nice Product”
Really nice product. Lays down easy and very durable. Made my hardwood floors soft to walk on and quiet. I would recommend for sure.
“Makes the Flooring Comfortable to Walk On”
Excellent product, really makes the flooring comfortable to walk on. We have a concrete slab and it tends to be cold but this product added a bit of warmth.
“This Product is Awesome”
The underlayment is critical to a good vinyl plank flooring install and this product is awesome! You can cut with a regular scissor and the ceiling tape is already on it. Vapor barrier is durable. You just have to put some weights down to keep it from curling up when you unroll it.
“Very Easy to Work With”
Very easy to work with, nice tape system, feels great.
“Totally Transformed the House”
The ‘dampness’ feel and associated odor is totally gone now. Basement is as fresh feeling and smelling as the main and 3rd level of the home. Totally transformed the house. Will use this for all new flooring going forward regardless of location in our home.
“We Are Impressed”
We are impressed with its extra cushioning, sound dampening qualities and added insulation on our concrete slab floor.
Excellent quality! I installed on the second floor above the master bedroom and EcoFoam provides superb sound installation. I plan to use it in another room, proof that this product performs to its sound insulation specs.
“Buy This Underlayment”
If you want an underlayment that lays dead flat, is firm and supporting, yet forgiving with subfloor imperfections and will make your new flooring feel awesome to walk on then don't hesitate. BUY THIS UNDERLAYMENT!!! You won't be sorry.
I was really impressed with this product. I have used other underlayment that was supposed to absorb sound but didn't work. My mom lives below me and she can't hear me exercising above her any more. I have a recumbent bike. She can't hear the vibrations or the mechanical noise from it. It was very easy to work with. I will be using it again when I do the other two bedrooms.
This was the perfect product for my application. Quick delivery, too!
“Very Quiet and Soft”
Had this stuff installed for a few weeks...very quiet and soft. I replaced carpet with vinyl flooring and this underlayment...feels very good!
“Quiet and Easy to Lay”
Quiet and easy to lay. The customer service lady returned my call promptly and answered all my questions. Highly recommend.
It was easy to assemble and light to carry also absorbs the sounds when you walk on. It’s really good.
“Easy to Install”
This product was easy to install! When completed, our floors were quiet and warm. The vapor barrier film worked well and sealing it was just pulling off the tape strip and overlap the film flap. Very fast very simple. The product lays flat and smooth. We had no trouble installing our plank flooring over it.
Very good quality, easy to lay down. Also very durable and doesn’t tear. Used with 1200 sq ft of Laminate flooring. Provided good sound dampening. Highly recommend!
“Will Use This Again”
This product is far better than what I used in past reflooring jobs. No hollow noise when walking on flooring, nice sealing of moisture barrier, ease of install. Will use this again. A little pricey, but well worth the slight extra cost.
“By Far the Best”
I have laid down many laminate floors in our entire home and in other homes for family members, and this underlayment is by far the best. Very easy to work with, cut, and laydown. After completing the floor, walking on it seems alot quieter, softer, and warmer. I decided to pay a little more for top quality underlayment, and a little less expensive of flooring, and I am real glad I did. Very happy indeed.
I used this product under engineered click flooring. It is very stable, yet has more cushioning and is thicker than other underlayment material I compared it with.
“Feels and Looks Great”
It’s very easy to install. The sealing strip works well. It feels and looks great!
“Glad I Chose this Product”
Great product. Does exactly what it advertises and I am glad I chose this product.
This stuff is the best underlayment I have ever used. Installation was a breeze and I really liked how the 6mil poly was attached to the cork and had a flap on one side and adhesive on the other, it really made install easier. I will continue to use this product in the future.
“Very Fast, Very Simple”
This product was easy to install! When completed our floors were quiet and warm. The vapor barrier film worked well and sealing it was just pulling off the tape strip and overlap the film flap. Very fast very simple. The product lays flat and smooth.
Superior product! Very pleased with the quality. It surpasses the previous product we used by far in thickness and sound absorption. Very easy to use, did not have to worry about it moving out of place. Would definitely recommend and buy again.
“Made in the USA”
Eco is the way to go! Super easy and just so happy to use a product that is well made and made in the USA.
Do you have to go up the sides of the walls on a basement concrete floor?
ECF is not intended to be installed on the walls approved for use on wood or concrete subfloors. If you have cracks in the foundation or are aware of high moisture and PH levels, then ensure these are addressed prior to flooring installation.
My concrete slab is not perfectly level, even after I had some areas dealt with. Will this help to reduce some of these slight dips?
ECF is 3.2mm thick and will help with minor leveling and imperfections in your subfloor. If the floor is not level, then it is very important to ensure you have a level subfloor before installing ECF and your flooring. When your subfloor is not level, the tongue-and-groove connections of your flooring will separate. Not only does the floor look sloppy when this happens, you tend to get uneven wear and tear.
What is the FIIC rating of Eco Cork Foam?
FIIC refers to a "field" test done outside of a lab. This "test" is only accurate in the place it was tested. If you were to perform a test the same way in a different location, the results will not be the same. FIIC rating sounds good, but this is not an accurate measure for the consumer. The industry standard tests are STC (used to determine airborne sound transmission loss), IIC (used to determine the amount of impact noise isolation) and Delta IIC (shows what the product adds to the assembly in terms of impact sound isolation). Delta IIC may be a helpful measure to the consumer as it explains the sound isolation for the product alone. Eco Cork Foam was tested by an independent, third-party laboratory, and the results were as follows: IIC is 73, STC is 66 and the Delta IIC is 23.
Can ECF be used on top of a DRICORE subfloor and under an engineered laminate hardwood floor?
ECF is the best choice when installing laminate, engineered and hardwood floating floors on a wood subfloor. Speaking in terms of order of installation, you would lay the DRICORE first as your subfloor, then ECF and followed up by your engineered laminate hardwood floor.
What kind of tape do you use with Eco Cork Foam?
It is recommended you use heavy-duty duct tape, preferably waterproof to seal the perimeters (concrete subfloors ONLY).
Is the amount of cork vs. poly blend of this product a food source to subterranean termites?
Our product is made from polyethylene foam and cork. While the foam is likely not interesting to termites, we do not have any testing or reports in regards to insects. Of note, we have never received any complaints regarding insect issues as a result of using Eco Cork Foam as the underlayment. (Over 80 million square feet sold!)
Can I use ECF on my walls to reduce noise transfer from room to room?
ECF has never been sound tested for wall installations, and is approved for concrete or wood subfloors. That being said, ECF was third-party tested and recorded best-in-class results for STC (66), IIC (73) and Delta IIC (23) for flooring systems. As ECF has a 6 mil vapor barrier pre-attached, there is no logical reason it could not be used underneath drywall in place of the simple vapor barrier approved for use in the IBC (International Building Code).
Can I install this Eco Cork Foam direct to the basement floor, or do I need a subfloor?
ECF is the best choice when installing laminate, engineered and hardwood floating floors on a concrete subfloor. Assuming you have a solid subfloor that is free of moisture and debris, the installation of ECF is fast directly on the concrete. The great news is that there is a 6 mil vapor barrier already attached!
I have concrete floor in the basement, and I want to install cork underlay as vapor barrier on the concrete floor with laminate floor on the top. Will it stop damp/coldness of the concrete floor from getting through? In the past, I had good-quality underpadding with thin commercial-quality carpet, and it worked.
ECF is the only underlayment available with an attached 6 mil vapor barrier. This vapor barrier is laminated across the entire surface with a 4” overlap that is utilized for installation on concrete subfloors. Not only is ECF waterproof, but it is also a superior thermal barrier and helps to retain warmth in your space.
What is the STC, IIC and Delta IIC of Eco Cork Foam?
ECF was tested by an independent, third-party laboratory. ECF performed excellently, and the results were an STC of 66, an IIC of 73 and the Delta IIC of 23. For both STC and IIC, a rating of 50 or above will satisfy the minimum requirements of the International Building Codes (IBC). The test reports can be found on www.ecfunderlayment.com.
Can this product be used with carpets in a basement?
ECF was designed specifically to be used with laminate, engineered, and hardwood flooring and is manufactured to 3.2mm thickness for this purpose. It is not the ideal underlayment for use with carpet. Speaking in terms of foot-fall comfort, we recommend the LifeProof Carpet Cushion. It is completely waterproof and will provide excellent thermal R-value, which only adds to the total comfort of your flooring system.
Is Eco Cork Foam (ECF) waterproof?
Yes, ECF is made from polyethylene foam that is inherently waterproof. Add to this a pre-attached 6 mil vapor barrier, and you can see why Eco Cork Foam is completely waterproof and top of its class.
I’m thinking of using the Eco Cork Foam as an insulation inside a fiberglass camping trailer. What is the R-value of it? Can it be glued to fiberglass? Can it be painted over?
While not the intended application, we feel ECF could be of benefit as thermal insulation as it has an R-value of 0.48. ECF is completely waterproof and is the only underlayment available with an attached 6 mil vapor barrier.
Can we use two layers of Eco Cork Foam to improve the acoustic performance?
We do not recommend using two layers of underlayment. You could actually create more moisture between the layers, providing an ideal environment for the growth of odor-causing mold, mildew and bacteria.
Should I tape the foam pieces together? I’m installing on a basement cement floor, should I duct tape them together?
ECF is the best choice when installing laminate, engineered and hardwood floating floors on a concrete subfloor. ECF Underlayment is easy to install as you simply lay flat on subfloor, fold the flap over, and peel and stick as directed. Tape can be used to seal the perimeter of the underlayment down to the concrete.
Can Eco Cork Foam be glued down on a concrete subfloor?
ECF is not compatible with any glues or adhesives as they could affect the integrity of the product. The approved installation methods are a floating or nail-down application.
Can Eco Cork Foam Underlayment be used with radiant flooring?
Eco Cork Foam Underlayment is approved for use with radiant flooring systems. We recommend that the temperature does not exceed 81 degrees F or 27 degrees C. Please follow the manufacturer’s guidelines for the order of installation and floor heat temperatures as excess floor heat can cause warping, cupping, shrinkage and sometimes splitting of laminate, engineered or solid wood floors.
Can ECF Underlayment be used under tile?
ECF was designed specifically to be used with laminate, engineered/hardwood and vinyl flooring that is 5mm or greater in thickness. ECF has some cushion and is not a rigid product, therefore, it is not an ideal underlayment for stone or tile applications.
Can Eco Cork Foam be used with vinyl flooring?
Yes, Eco Cork Foam can be used with vinyl. ECF was specifically manufactured to be used with engineered/hardwood, laminate and vinyl that is 5mm or greater in thickness. Be sure to follow the flooring manufacturer’s installation guidelines.
Can Eco Cork Foam Underlayment be used with flooring that already has attached underlay?
Yes, ECF can be used with flooring that has an attached underpad. It is recommended to follow the flooring manufacturer’s installation guidelines as requirements can change from brand to brand.
May ECF be used on a 6” concrete floor with no subfloor as is requested by my association?
The concrete floor is actually your subfloor. ECF is the only underlayment available with a built-in 6 mil vapor barrier which makes it the best solution for concrete subfloors. No other materials are needed to complete your project to protect your floors from moisture. ECF has a Class 1 rating for water vapor transmission and best-in-class acoustical ratings.
How thick is Eco Cork Foam?
Eco Cork Foam has a thickness of 3.2mm or 1/8", which helps establish a solid foundation and provides stability for solid tongue-and-groove connections.
