What Customers Are Saying

Customers overwhelmingly praise this underlayment for significantly reducing footfall noise, providing moisture and mold resistance, and simplifying installation under vinyl flooring on concrete. Many highlight the cushioned comfort underfoot, especially in high-traffic areas, and appreciate how the built-in adhesive strips and overlapping edges make it easy to lay, cut, and align without additional tape. Reviewers note it remains stable and doesn't crimp or warp like thinner alternatives. A few mention concerns about pricing or unclear instructions, but most consider the quality and performance well worth the investment.

Quiet

Would Recommend

I've used several different underlayers when installing laminate flooring and I would rate this as better than average. For the price it is as good as you'll get. It is quieter than the cheapest and doesn't cost much more. I feel like it will allow for the laminate to last longer since it appears to be more durable than the cheaper underlayment.

Good product

Would Recommend

I am currently working on a whole house renovation project and I wanted to purchase the very best quality items for this home as it is for my dad who has cancer. I found the USA made product that has an R rating of 4 and is 1mm thick faom which is very good for 1mm and is easy to install. It comes in 3.3 foot section rolls style so it doesn't want to lay flat right out of the package but the small rolls make it easy to handle. This 1mm provides provides vapor/moisture barrier and is ...

Good, for the price you pay

Would Recommend

I hate to overpay for something that you're never going to see and which tends to get overpriced by the flooring industry. Underlayment is like that. You can pay big bucks for something that is more than you really need. This product is basic, like most Project Source products. It will provide minimal cushioning and moisture control, but most times that's all you really need, especially if your flooring has a pre-installed backing. Don't overbuild or overpay if something like this will be suf...

Thin but effective

This is proof of how far engineering has come, this Underlayment is thin but delivers all that is required, sound deadening attribute, moisture barrier. And a built in lip to make taping easy. This only install on way. Very durable and easy to handle.

Great padding under LVP flooring

Would Recommend

I used this under my LVP flooring even though the LVP had an attached pad. This was going over a concrete floor on our house as it is on a slab….we wanted a little extra padding with it being over the concrete. This padding goes down well and flat and you can definitely tell the difference with and without. I have one small room without the padding and I’m going to go back and pull up the flooring to put this padding under it as well. Works very well for the money! Highly recommended!!

Great underlayment for LVP

Good product

Would Recommend

Used this under the vinyl plank flooring even though it was needed. Just added an extra layer of protection. Would prefer it to stick to self at the seams but was able to do a work around.

Project Source Foam Underlayment

Would Recommend

Project Source 100-sq ft Standard 2-mm Flooring Underlayment is a foam Underlayment for laminate or wood floor. We used on a wood floor. It is very simple to install and lightweight. It is a 2mm polyethylene foam laminated with a vapor barrier. It is a quality product and very easy to remove the film and spadhere to your sub floor. It’s not fancy but does the job at a great price.

Quality Product

Would Recommend

I selected this vinyl underlayment online. The rolls were larger than expected. That is definitely a plus. It’s made from a quality material that I’m sure will cushion and insulate my new wood floors when they are installed. It can be used with flooring material that comes with or without pre-attached underpayment. The cost was less than comparable brands; however, Project Source never disappoints. I have used Project Source home improvement materials in the past, and they always remain li...

more than floor enderlament

Would Recommend

this underlayment is dense. i can see where it would stay in place when laying down your laminate floors. i do believe it would make the floor more noise proof. i can think of other uses for it also such as padding on the floor in a work shop or the deck of a boat for more cushion on the feet. its 1 mm, each roll is grey with 100 sq ft per roll

1mm Floor Unerlayment

Would Recommend

Ok, laid down easily enough, still have to do 2 bedrooms, lol. Always a plus when it has a self stick tape area as shown in pic. Just wish this stuff was cheaper.

Good product

Would Recommend

This underlayment is made of durable material and was very easy to use in the area I needed it for. Easy to cut and very easy to use with the recommended flooring or any other flooring material. I’m also planning on using this material in another non-flooring application soon, very good product and it is reasonably priced. Very satisfied
