Product is US certified after passing the strictest acoustic tests (6” concrete slab without ceiling assembly), it reduces sound transmission and improves acoustics. Natural and sustainable sound proof padding (no emissions, no VOCs, no glue, recyclable) enhances safety and value of the property. The Steico Wood Underlayment is a product for multiple needs.

It is made using Binder-Lignin (Wood- Tar), can absorb moisture up to 20% of its weight and dry after without loss of properties, it is called “Water Vapor Open System” and it allows air to circulate! The product is easy and fast to install. Steico Underlayment is produced in Europe.

    • INCREDIBLE Underlay material.

I was about to lay 3/8" Engineered Hardwood (Flooret Silvan) directly over tile, considered the Steico product and wondering whether I would need to pre-fill the grout lines (~1/4" wide by 1mm deep - tile is 20 x 20). Sunco (whose support has been fantastic!) of course gave a, honestly not unexpected reply, that their std recommendation would be filling the grout lines (not unreasonable). But while not endorsing per se, they had knowledge of users who had not and it appeared to be working out. I decided to go for it and have done a double layer (staggered pattern) over a 1/8" lower tile level and single level 1/8" (3mm) over the main area tile as per the image above. I did a test - with the 3mm product (only, no plank yet) I aggressively pounded /stamped / jumped/ beat on it above the grout lines and could NOT get them to telegraph even to the bottom side let alone through to the top! So I may get some disagreement from the community here on pre-filling but with my test and the fact that the engineered wood flooring in itself is quite rigid, I had no qualms about going straight over as-is. Image shows an area that had a tile field that was exactly 1/8" below the main tile level: I believe house originally had carpet section there and previous owners filled with a different tile, but not fully flush up to the other tile. So for this section I put one layer of 3mm in to exactly fill that section to its perimeter with the other tile, then a complete layer of additional 3mm over everything. I was careful to stagger the joints so they did not overlap between first and second Steico layers, nor the planking joints. (for the plank it's easy - fraction over 7" wide which is not a factor of 24 or 36, so it will naturally not create any joints over underlayment seams.) It is SUPER easy to work - cuts easily. I personally found scissors a better tool than a Blade. And I wondered if it would be more work than 'roll' type underlay which I have used previously. Actually I found it to be convenient - one row of 2' panels would accommodate 3 rows of plank and I could just lay as much underlayment as I chose to work my way across room (while juggling furniture around) The result underfoot is that it feels great - indeed quiet and comfortable, and that is also borne out when witnessing from level below. I am absolutely delighted by this product and would not hesitate to recommend this product to anyone. ... show more

    • Nice product
Size: 6mm(1/4in) Thickness Style: 180 Sq Ft
This is easy to work with. Simply lay down and I like to tape them together, but it is not required. The product is soft and breaks easily, so you just have to work with it carefully. My base boards were so high that i needed to raise my new flooring by 1/4 inch. This did it perfectly.

    • Great floor underlayment, very dusty
Size: 6mm(1/4in) Thickness Style: 90 Sq Ft
I used this floor underlayment on a 360 sq ft floating floor. It worked great, installed very easily. You can cut it with a simple swipe of a utility knife and then a bend and the product will break on your line. It WILL make a ton of green dust everywhere while you are installing. After installation our floor was solid and it does seem to have a sound dampening property because it is noticeably quieter in our basement under this floor than previously. ... show more

    • Good stuff, and easy to use
Size: 3mm(1/8in) Thickness Style: 90 Sq Ft
Excellent product!! Installed myself with a friend under 5mm LVT click-lock planks. I am very happy with this choice. First, underlay comes in sheets and it is so much less headache than rolls. Second, I really loved the sturdiness of the boards, floor feels very stable. A few years ago I used somewhat “foamy” underlayment and it was so annoying how locks slightly but noticeably bended and squeaked while walking, so now I decided to choose something else and it worked as advertised. Third, I did not do any leveling of the concrete and that saved me both money and time. At the beginning I was little skeptical because the concrete was a bit uneven, so we tried it on a small area. It worked great and we decided to go ahead and install it all. This fiber material absorbs the bumps from the downside and keeps it straight from the top level. For the sound transmission we have noticed that running steps of our boys sound softer, but it was not an issue from the beginning. Overall, installation took one day and it was easy, recommend! ... show more

    • Good product but buy elsewhere.
Size: 3mm(1/8in) Thickness Style: 90 Sq Ft
I'm just going to start out by saying that I am a DIYer, not a professional of any kind! Ioriginally purchased this from Lowes in the 6mm thickness, and have installed it in 2 bedrooms and a hallway so far. I find it very easy to install and it works really well over my slightly uneven floors (my house is 91 years old so there's only so much that can be done!). It does make a lot of green dust when you cut it and walk on it, and I really detest the way it feels on my feet, but once you install your flooring over top that isn't an issue anymore. I will definitely update this review if I run into any future problems! I needed one more package of this and decided to purchase from Amazon because I thought it would be faster. It probably was, but shipping did not do my underlayment any favors. The box was partially open, and I'm not sure if it was just damaged in shipping or if they sort of wrapped the package in cardboard and sent her out. Anyways, the plastic covering the underlayment was torn open, the ends are all chipped off and the box was basically falling apart when I received it. It's usable, but I will definitely not be purchasing this from Amazon when I get around to redoing my downstairs office. ... show more
