Questions & Answers

I plan on installing Vinyl Plank Flooring in my basement. Currently has cement floors. If I lay this down, can I install the planks directly on top or do I need to also install a subfloor on top of this before putting the planks down?
ByNov 4, 2025
1 Answer | 
Answer This Question

Yes, you may install LVP directly on top of Eco Cork Foam underlayment. When installing over concrete subfloors, you will need to use additional tape to seal off the perimeters of the room/s. For installation instructions: please visit our website ecfunderlayment.com, click on "RESOURCES", and select the language desired from the "INSTALL INSTRUCTIONS" to download the steps. Feel free to call us at 855-810-8922 for additional questions. Good luck with your project!

        Can this be installed directly over deck boards on a screen covered porch?
        ByOct 19, 2025
        1 Answer | 
        Answer This Question

        Thank you for your interest in Eco Cork Foam underlayment! ECF was created for interior use with wood, laminate and LVP flooring over a wood or concrete subfloor. ECF has never been formally tested for exterior installation. That being said, ECF is waterproof and has a 6 mil vapor barrier pre-attached so you should not have any challenges but we cannot recommend as 3rd party testing has not been completed. We hear of so many interesting and innovative uses of ECF every day from happy consumers who share their projects with us so please share pictures if you use it for your intended application and good luck with your project!

          Can this be used under 24 x 48 porcelain tiles?
          ByOct 18, 2025
          1 Answer | 
          Answer This Question

          Eco Cork Foam underlayment is not rigid and has some cushion (3.2mm) that allows for a small amount of movement. Therefore, it is not an ideal underlayment for stone or tile applications. Please visit our website at www.ecfunderlayment.com for more technical information.

            Answer This Question

            Thank you for your interest in Eco Cork Foam. ECF is NOT approved for use with any glues or adhesives as they could affect the integrity of the product.

              Is this underlayment great for Malibu Wide Plank Rigid Core Designer Vinyl Flooring with ArmorCore Technology in 7 mm total thickness with 30 mil wear layer and a 1 mm thick pre-attached underlayment to each plank?
              BySep 17, 2025
              1 Answer | 
              Answer This Question

              Eco Cork Foam underlayment is applicable with vinyl floorings that are 5mm or greater in thickness. Your vinyl flooring wear layer of 30-mil thickness is equivalent to approx. 0.76mm, coupled with a 1mm pre-attached pad, so as long as the floor itself is at the required thickness of 5mm or greater, it should indeed be great!

                How well does this work on cold concrete floors
                BySep 17, 2025
                1 Answer | 
                Answer This Question

                ECF will work perfectly! Eco Cork Foam is the #1 Rated underlayment at The Home Depot and we have the receipts to prove it; just check out customers 4.8-star rating reviews! ECF is 3.2mm thick with a patented built-in 6-mil vapor barrier that helps reduce the absorption of warmth that concrete pulls from rooms while protecting your new floors from vapor mists that concrete naturally releases over time. ECF has an R-value of 0.48, acts as a natural insulator, and diminishes drafts resulting in less heat loss to concrete. ECF is easy to install and saves time.

                  Adhesive strip flawed
                  I bought this the other day to lay under my luxury vinyl flooring. When I went to use the adhesive strip the plastic from the strip next to it wasn’t even long enough to reach it. I had to use waterproof duct tape to attach the rows together.

                    Good Product!
                    I bought this to go under LVP flooring and it has worked well! It has a bit of a squishy feel to it which helps the flooring feel softer under our feet. It was easy to cut with a utility knife, but it does tend to curl up. Overall, would recommend, even though it’s a little pricey.

                      The product worked well, we bought two rolls and both had areas which were ripped in manufacturing and had to be cut out and patched. A printed grid pattern on the top side would help with measuring and cutting if that could be added to future production. Otherwise the product worked very well.

                      I used this under garage floor tile. It was successful in helping to reduce the noise from walking on the plastic tile against a cement floor. It was strong material but easy to cut for corners and walls.

                      Do not recommend: packaging material tore underlay
                      Bought 200sqft worth of this material and had really high hopes. Which were quickly crushed when I tried to open the underlayment. Whoever packaged it, had no regards for the type of material. The tape was so strong that it tore away parts of the underlayment. I am not confident it can fulfill its purpose anymore. Do not recommend.

                        Very Easy Installation / Good Quality
                        I found this product to be very easy to install; the thickness covered up tons of broken tile spots, I have not put down the flooring just yet but from walking on it, you could not feel the cracks and imperfections underneath on the subfloor.

                          It is good stuff. But each roll is diffrent and inconsistent product. 1 roll has a nice flap with a black line that go over the tape on next roll. The next one has diffrent laying over it and the plastic seams a lot weaker.

                          Adhesive Strips did not line up!
                          So there’s a white pull strip that had adhesive on one side and plastic fold over on the other. I used 3 different rolls and the plastic fold was almost 1 inche short then the other and would not properly seal. For the price of this stuff is should have Atleast alligned correctly. Really disappointed in it and quality wasn’t all that great. Wouldn’t purchase again. Honest review
