What Customers Are Saying

Customers overwhelmingly praise this underlayment for its straightforward installation, effective sound dampening, and excellent value. The peel-and-stick adhesive strips, lightweight design, and self-adhesive edges make laying it simple and precise. Many report significant noise reduction from footsteps and pets, with a noticeably softer, more comfortable walking experience. Users consistently rate it as superior to cheaper foam alternatives and more expensive brands, appreciating the built-in vapor barrier and versatility. A few mention minor issues like unclear instructions or imperfect initial flatness, but most consider it reliable and worthwhile.

Little over priced

Would Recommend

I’ve done a good amount of flooring and have used different underlayments. I have an addition over my garage where I am installing flooring. There is some installation but cold air is coming up in on floor seam. I noticed this blocked the cold from coming through. There’s a good amount of overlap which makes it easy to install. Not much padding to it but it helps with sound also. Over all I would use it again.

Quality underlayment

Would Recommend

We had just been putting moisture barrier down for the majority of the LVP tile install but wanted a little more sound proofing in the laundry room. This underlayment fit the bill perfectly. Easy to lay out and install over, giving us a nice finished product!

Flooring Underlayment

Would Recommend

Having laid several floors and using a variety of underlayment products, this product is thicker, easier to use than lighter weight products. If laid appropriately, it should provide moisture and sound protection, vapor barrier and adequate cushion under laminate, LVP or on top of concrete. The built-in lip and adhesive strip makes for easier installment. The strength of this product will make it useful for other applications.

A Must Have for Do-It-Yourselfer's

Would Recommend

I found out a lot of things when putting down an underlayment and it's not that simple for concrete floors. Moisture is the key to controlling seepage from your concrete floor and should be tested first to determine what's best for your situation. A lot of things to consider and one of them is the type of flooring you're planning to use, the "R" value, and the thickness of the underlayment. Take your time and don't be in a rush to finish, this will make the floor replacement worth the effort. F...

Does the job.

Would Recommend

The underlayment was used for a barrier between cement and laminated wood flooring. So far so good. I will see how effective it is in the spring, when condensation from the thaw comes around. Then a review would be more accurate.

Underlayment

Would Recommend

I have installed this type of flooring several times and always use underlayment. This doesn't appear to be the foil type but isn't whimpy either. It's just underlayment not rocket science.

Great features

Would Recommend

This product is easy to install, and lays flat on the wood floor. The adhesive tape is a bonus to prevent movement. It provides a cushion to the wood floor which will be wonderful under the LVP flooring. However, it doesn't seem to provide as much sound barrier as I had hoped.

Flooring underlayment

Would Recommend

This looks to be a very good product. Nice and thick with overlapping plastic lining with self adhesive strips. This will make a really nice vapor barrier for you project. Very easy to cut and get it laid down where it needs to be.

Flooring underlayment

Would Recommend

Was so pleased to receive this flooring underlayment as we are replacing flooring in several rooms. It looks to be durable and high quality and easy to place. And this is the perfect amount for one small room. Unfortunately our plans have been delayed so will have to update this review when completed. in the meantime will purchase additional for the other rooms and possibly some from another brand to compare.

Looks Great!

This came at a great time. One of our daughters is planning to replace the laminate flooring in one of her rooms. This looks to be thinker than described. We are looking forward to installing it.

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.
