Wood Fiber Flooring Underlayment, 6mm (1/4 Inch) Thickness - 90 Sq Ft, Natural Soundproofing Insulation, for Laminate, Vinyl, LVT, LVP, or Hardwood

Without nails or screws the installation was painlessly easy, without fasteners the only possible squeeks will be from the original subfloor too. Unlike plywood, minor imperfections are absorbed and cannot be detected or leave gaps below it as plywood would've (another source of squeeks). Definitely a huge difference walking on the floor with this underlayment, the sound deadening will reduce the impact noise from walking on any sold surface flooring installed over it.With my installation it was more cost effective (less leftover) to use two layers of the 1/8 inch product, this also allows you to "carve" out larger imperfections on the first layer and bridge it with the second.Having it delivered to my door of my winter getaway was another plus, no renting or borrowing a truck for plywood underlayment let alone the mess and extra labor of cutting, nailing/screwing to install it.Great product, I'll certainly use (and recommend) it again.

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!

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.

It is hard to write a complete review of this product because I am in an upstairs condo unit and can't really say how the neighbors below feel about the noise transmission. Let's just say that they have made no complaint. These pieces of underlayment are easy to put down (I have to confess that I didn't put them in at a 45 degree angle to the flooring). The first package gave us a lot of green dust, but later packets seemed not to. I suspect that the difference was that after box 1 (I used 8 boxes), I figured out that the best way to "cut" these pieces was by using a straightedge and scoring the piece with a chisel or screwdriver and then just folding on the scoring -- easier, cleaner and faster than using a blade.This product also had the highest Delta IIC rating I could find for an underlayment. The ratings for underlayment are very misleading. They show ratings for IIC and STC that are based on particular configurations of concrete and wood joist subfloors that may exist somewhere, but probably not in my 1980's condo. The Delta IIC, on the other hand, provides a rating that indicates how the underlayment performed in deadening impact noise when added to a subfloor. Thus it is a measure of how the product adds to a subfloor configuration. Maybe this isn't the best way to judge, but when 1/4" of cork has a Delta IIC of 24, you get a pretty good picture that perhaps this 3mm with a Delta IIC of 25 is the real deal for sound deadening.I had used some roll foam underlayment in two closets and it was a pain in the butt to roll out and get to lie down. These lie flat from the get go and it was much easier to lay down.

Overall, this is a decent product. It helps capture moisture and is a great price. I thought it would be thicker, and wished it was slightly thicker. I like that it is sustainable. It is easy to cut. However, when using it, green fibers were everywhere and irritated our throats. Some boards were also mildly with black spots, which we did not like. It is flat, but the texture is soft and we wanted harder. Overall, it is a decent product for our budget and did the trick.
