NICHT KAUFEN, ich habe lediglich 8qm erhalten - leider wurden nur ca 8,5 qm geliefert anstatt der wie beschriebenen 90qm, das liegt vermutlich daran das die einheiten falsch bzw gar nicht umgerechnet wurden ich habe wie schon beschrieben 90sqft erhalten. ALLE PRODUKTE VON STEICO KANN ICH NUR EMPFEHLEN.... Review: Good stuff, and easy to use - 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! ## Features - Increased room comfort: Room comfort is enhanced by The High-performance sound control and acoustic improving properties of the underlayment. - Highest rated sound proofing: US tested and certified after passing the strictest acoustic tests (6” concrete slab without ceiling assembly) which guarantees optimal sound proofing. - Enhances safety: Absence of VOC and other emissions makes the living space safer and more valuable. Natural product made of pure wood fiber material without any glue additives. Easy to handle and install using commonly available household tools. - Squeak-free floor: High compression strength protects the "click-lock" system of floors, ensures that the floor will not squeak, prevents "springy" effect when walking and increase floor longevity. - Breathable product: “Vapor Open” technology prevents accumulation of moisture under the floor. Being a natural and porous material, it can absorb 20% of its weight in water and thus prevent a minor leak from spreading. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LD0RC24 | | Brand | STEICO | | Brand Name | STEICO | | Coverage | 90 square feet | | Customer Reviews | 4.3 out of 5 stars 202 Reviews | | Global Trade Identification Number | 05901115306375 | | Item Thickness | 3 Millimeters | | Item Weight | 5.9 kg | | Item thickness | 3 Millimeters | | Manufacturer | STEICO | | Manufacturer Part Number | PR16005955 | | Material | wood fiber | | Material Type | wood fiber | | Model Number | PR16005955 | | Number of Items | 90 | | Recommended Uses For Product | Sound Insulation, Floor Protection, Leveling, Radiant Heating Compatibility | | Recommended uses for product | Sound Insulation, Floor Protection, Leveling, Radiant Heating Compatibility | | Unit Count | 90 Square Feet | ## Product Details - **Brand:** STEICO - **Global Trade Identification Number:** 05901115306375 - **Item thickness:** 3 Millimeters - **Material:** wood fiber - **Recommended uses for product:** Sound Insulation, Floor Protection, Leveling, Radiant Heating Compatibility ## Images ![STEICO 3 mm 1/8 Inch Wood Fiber Flooring Underlayment for Laminate Vinyl LVT LVP Hardwood Floor 90 SqFt Natural Sound Insulation Barrier - Image 1](https://m.media-amazon.com/images/I/81ANy80y5DS.jpg) ## Questions & Answers **Q: Do you have to use a seperate vapor barrier over concrete floors when installing engineered wood floors** A: Dear rwm925,Thank you for your question! Vapor barrier should be installed ONLY if the the installation is in a basement that is very damp and humid, or a first floor of a house without a basement and also with the same moist conditions. If the floor you are working on is in upper floors, or not in a dry humid environment, vapor barrier is not needed. Also, vapor barrier might be needed if the concrete slab is newly poured, and it did not have enough time to cure and dry. Otherwise, by all means, use without any barrier. It will benefit your microclimate in the house. We hope this helps you and please feel free to let us know if you have any further questions.The SunCo America Team **Q: I am installing evp or lvp flooring, will this underlayment be ok?** A: Since vinyl isn't rigid like laminate or other wood type flooring I find out that cork maybe better option because of higher PSI sq ft especially when you use 1/4 option or more. Being this say manufacturer recommend this underlayment and I would use 1/8 version without blink of an eye. Simply I love it after I done laminate floor. **Q: Can you put down vinyl planks with peel off back (adhesive) on this?** A: I do not recommend doing that as these are made out of compressed material. So if you glue any thing to it it will just fall apart **Q: Do I need to adhere this to the current brick paver floor or just lay it on top? If it needs to be adhered, what should I use?** A: There is no need to to use an adhesive. You can simply lay our product on top of the existing floor and lay the finishing floor on top of it. For more comfort of installation, you can use small pieces of adhesive tape to connect the wood underlayment sheets with each other. However, if the gaps between bricks in your current brick paver floor are deeper than the thickness of the underlayment you want to use, we suggest you to level the existing floor first. Also, in order to avoid matching of gaps between bricks in your current brick paver floor with lock system of finishing floor, we suggest to lay down the underlayment with an angle against the gaps between bricks in the existing floor as it is written in our installation instructions (you can find a downloadable copy in our listing). We hope this helps you and feel free to reach out again with any other questions you might have. SunCo America Team ## Customer Reviews ### ⭐ 90sqft sind nicht 90qm !
